Sister Ar'a's background

This technique generally concerns fluid flow passages within flow control devices, such as those particularly suitable for use in high-pressure oil and gas production and processing systems.

<p dir="rtl">5 One type of flow control device is a valve. In general, a valve is a flow passage and includes a container that operates selectively to open or close the flow path to control fluid flow through the valve. The sealing integrity of high pressure valves must not only perform at high fluid pressure values, currently 103421.39 kPa (15,000 psi) and higher, but must also do so with fluid flow control</p>

<p dir="rtl">10 Corrosive and/or abrasive feeding the internal components of the corrosive valve in the oil and gas industry.</p>

The embodiments herein relate to a plug valve although the embodiments are not restricted. In a valve plug, the flow path typically includes a valve body connected via fluid to two or more openings, ideally an inlet opening and an outlet opening, which form a flow path through the valve body. Plug valve and insert clips

<p dir="rtl">15 segments, one type of valve closure described here, is placed in a valve body bore between the inlet and outlet holes where the plug, insert, and hole are sealed. The valve stop defines a through-opening and is optionally rotatable to an open position where the bypass is aligned with the flow path to allow fluid to flow through the valve (from inlet to outlet), or to a closed position where the bypass is not aligned with</p>

<p dir="rtl">20 Flow path to prevent fluid from flowing through the valve. Operating the valve in difficult oilfield conditions can lead to corrosion of the valve body hole as the fitting in the fitting scrapes against the hole, often leading to leakage over a short time. Valve body repair, such as by welding and machining, represents a problem and inconvenience in the oil field.</p>

Illustrative embodiments of this technology relate to plug valves that are not restricted to said embodiments of this technology. The expert in the field will understand that in alternative embodiments this technology can be used in other types of valves that have differently configured housings. However, there are so many different types of valves that are suitable for using this technique that it is not necessary for an expert in the field to understand the perspective

<p dir="rtl">5 The subject to be protected, such that this pluralism is not guaranteed.</p>

In addition to valves, there are other types of high-pressure flow devices suitable for implementing this technique. For example, the fluid is used in many well servicing applications to contain high-pressure, often corrosive and/or abrasive, fracturing fluids in the oil and gas industry. The fluid end ideally includes a manifold body

<p dir="rtl">10 manifold body and a number of components mounted and secured to the body, such as suction and discharge plugs, suction and discharge valves, stuffing box, discharge flange, and suction manifold; With these components either singly or fitted with a bushing which are illustratively described. Like valves, operating the fluid tip in difficult oilfield conditions can cause body wear that results in leakage in a short period of time.</p>

<p dir="rtl">15 Body repair is a problem and a hindrance in the oil field.</p>

Improvements in the internal sealing of high-pressure flow devices are needed to increase life while reducing downtime and operating cost. What is needed is a solution that transfers wear (wear and abrasion) from the body of the high-pressure fluid flow device to a component that is flush with the body. There are improvements in these models related to this technology in illustrative models defined in the perspective of protection elements.

Detailed description:

In principle, this disclosure is provided as an example only, without any limitations. The 10 related explanations and methods disclosed will not be restricted for use or applications to the strictures of any particular assembly or in any particular environment. Therefore, the disclosed technology is not limited to use in sealing valves and fluid ends as described in the illustrative embodiments. Therefore, although the tools described herein are for convenience, and are illustrated and described relative to exemplary embodiments, an expert in the art will understand that the principles described herein can be equally used in sealing other types of high-pressure flow 15 devices.

Figure 1 is a cross-sectional depiction of a plug valve 100 configured according to previously implemented solutions. The obturator valve 100 includes a valve body 102 such that it has a tapered internal bore 104. Inserts 106a and 106b in these models form sections of an open hollow cone. Although two inserts 106a, 106b, 20 are depicted, said embodiments are not limited because more than two can be alternatively represented. Each insert 106a, 106b includes an outer conical surface a, 108b that tapers compatible for engagement against the hole 104 in a tight matching relationship.

The cylindrical plug 110 includes an outer diameter surface 112 of a specified size to fill the voids between the inserts 106, compatible with an inner 25 diameter surface 114 diameter surface a, 114b of the corresponding inserts 106. The plug 110 includes a top anchor

Opposite to the trunnion 118 to contain the pressurized fluid within the valve 100 while maintaining external force to rotate the trunnion 118 and, in turn, the plug 110. In these illustrative embodiments a handle 124 is attached to the trunnion 118 to allow a user to manually rotate the plug 110. In alternative embodiments not illustrated, the trunnion 118 may be rotated by a powered actuator

<p dir="rtl">5 actuator. The seal 110 includes a bottom journal 126 which rotates in the body 102 and is sealed by the packing 128.</p>

The body 102 also forms the holes 116a, 116b intersecting the hole 104, ideally referred to as an inlet and an outlet. For illustrative purposes of this description it is specified that the fluid flows through the valve 100 from left to right, or into the orifice 116a and out of the orifice 116b. However, when

<p dir="rtl">10 Implementation: Either slot 116 may provide the input and the other slot 116 may provide the output.</p>

Each insert 106 forms corresponding openings 130a, 130b, and the inserts 106 are mounted in the valve 100 such that the openings of the inserts 130 can be aligned with the corresponding valve body opening 116. The plug 110 forms a passage hole 132 that allows the user to optionally align the hole 132 with the openings.

<p dir="rtl">15 116. Figure 1 depicts a closed position of the valve 100, where the plug 110 is rotated such that it does not</p>

Align the pass slot 132 with the slots 116.

Specifically, in the closed position of the valve 100 depicted in Figure 1, the pressurized fluid connected to the orifice 116a (inlet) impinges against the closed seal 110, sealing the back side of the seal in a metal-to-metal seal against the fitting 106b and also sealing between

<p dir="rtl">20 The sealing device 140 is installed in the insert 106b between it and the valve body hole 104. Thus, in the closed position the pressurized fluid is prevented from flowing through the valve 100. By rotating the seal 110 to the open position (not shown), the bypass orifice 132 comes into alignment with orifices 116, which allows the pressurized fluid to flow through the valve 100 through the component flow path entirely by valve body orifices 116, fitting orifices 130, and valve seal orifices</p>

25 Passage 132.

Figure 2 is similar to Figure 1 but depicts a 100' overhead entry plug valve configured according to other previously implemented solutions. The plug valve 100' includes inserts 106a, 106b' configured as sections of an open hollow cylinder in place of the inserts 106a, 106b of Figure 1 which are sections of an open hollow cone. Or 5 In other words, the conical surfaces in Figure 1 are replaced here with cylindrical surfaces. For the purpose of this description the expert in the art understands that the details of construction and use of this technology apply equally to each of these valves, as well as other types of valves that are used to control high-pressure fluid. Therefore, the domain expert understands that the perspective of the protection elements of this description is compared to the construction details of just one of the previously implemented solutions.

<p dir="rtl">10 Continuing with the previously mentioned description compared to the previously implemented solutions depicted in Figure 1,</p>

Figure 3 is an enlarged portion thereof that more specifically depicts how the high-pressure fluid within the valve 100 is partially contained by the sealing device 140 that is compressed between the outer conical surface 108b of the insert 106b and the valve body hole 104.

The insert 106b includes a surface 139 that defines the recess 144 intersecting with the outer conical surface 15 108b. The term “intersected with” for the purpose of this description means the medium it constitutes

The recess 144 has a gap in the outer surface 108b of the insert 106b. Intersecting the socket configuration 144 with the surface 108b that allows a fixed end 141 of the sealing device 140 to be installed in the socket 144, and sizing the sealing device 140 such that a distal end 143 of the socket 144 extends beyond the outer conical surface 108b for sealing against the hole 20 of the valve body. 104. Importantly, this requires that the hole 104 defines a sealing surface against which the sealing device 140 in the insert 106b applies pressure to effect the sealed engagement of the insert 106b against the hole 104. A corrosive and/or abrasive fluid can be trapped between the sealing device 140 (installed in the insert 106b) and the hole 104 which causes erosion of the hole 104. The sealing device 140 is referred to in these embodiments for axial sealing 25 due to compressive forces from the surface 108b on one side and the hole 104 acts

On the other side, in an axial direction relative to the annular seal 140.

Although the embodiments according to Figure 3 depict only a single toroidal sealing device 140 surrounding the exit 116b, according to previously implemented solutions it is not constrained. An expert in the field will understand that in alternative structures more than one sealing method may be used to provide padding. The sealing device 140 may be an elastomeric seal, or in other embodiments other types may be used.

<p dir="rtl">5 Seals, such as metal seals, spring seals, and the like.</p>

To include the valve seal 110 and the trunnion support 118, the retaining nut 120 is notched into the valve body 102. The retaining nut 120 includes means of tightening by piercing the valve body 104 with another tightening means 146. Similar to the insert 106b, the retaining nut 120 includes a surface

<p dir="rtl">10 147 which defines the socket (specifically referred to as the “gland” nut 148) intersecting with the surface of</p>

Outside diameter 121 of the retaining nut 120. The sealing device 146 is supported in the recess 148 and is sized to extend beyond the sealing surface 121 against a sealing surface formed by the valve body hole 104. The sealing device 146 is referred to in these embodiments as the radial seal because Compressive forces from the cover surface 121 on one side and the hole 104 on one side

<p dir="rtl">15 The other side is in a diagonal direction Ratio of the annular seal 146. Although a diagonal seal is depicted, in alternative embodiments an axial seal, crush seal, and the like may be used instead of or in addition to the diagonal seal.</p>

By comparison, Figure 4 is similar to Figure 3 but depicts a portion of a valve 150 configured according to embodiments of this technology. Here the insert 151 is similar in some respects but includes a sealing device installed

<p dir="rtl">20 There is no recess in the surface 153 where the recess for mounting the seal intersects. Instead, the valve body 152 defines a hole in the surface 153 where it intersects the recess for mounting the seal. The valve body 154, also including the surface 155 defining the bore 156 intersecting the hole 154. Again, the term "intersected with" for the purpose of this description and meaning includes the protective elements</p>

<p dir="rtl">25 A means included in the recess 156 is a recess in the hole 154. Specifically, the retaining end 157 of the sealing device 158 is fitted into the recess 156, and because the recess 156 intersects the hole 154, a</p>

7787

-9-

The sealing device 158 is sized to extend from the recess 156 beyond the hole 154 such that the distal end 159 of the sealing device 158 seals against a sealing surface formed by the insert 151. A corrosive and/or abrasive fluid may be trapped between the sealing device 158 (which is mounted on the body 152) and the insert 151 which causes the outer cylinder surface of the insert 151. Importantly, compare

<p dir="rtl">5 With solutions already implemented, the configuration of Figure 4 advantageously transfers corrosion wear from hole 154 (of body 152) to insert 151. When corrosion has advanced enough to permit leakage, repair or replacement of insert 151 is significantly less complex and less costly than repairing Body 152.</p>

The body 152 also includes a surface 161 that forms another recess 160 which intersects a hole in the body 10 of the valve 154. The sealing device 162 is mounted on the body 152 in the recess 160. Again,

Due to the intersection with the configuration of the recess 160 and the hole 154, the retaining device 162 can be sized to extend beyond the retaining hole 154 against a sealing surface formed by the retaining nut 164. Unlike the retaining nut 120 of FIG. 3, the retaining nut 164 does not include a retaining device mounted thereon. Alternatively, the sealing device 162 is mounted on the valve body 152 and sized

<p dir="rtl">15 To extend the recess 160 for sealing against the outside diameter surface 166 of the retaining nut 164.</p>

In the same manner as above, this technology transfers wear and tear away from the body 152 to the less complex and expensive mating component, in this case the retaining nut 164.

Figure 5 is a simplified depiction of valve 150 configured according to the present technology. 20 An expert in the field will understand that there are many different images in the composition that are included in the models

This technique is mentioned and represented in illustrative models. For example, Figure 6 depicts another valve 170 configured according to this technique with each of the seals 172, 174, 176 being installed in corresponding recesses formed in the valve body 184 and intersecting the valve body hole 178. The seals 172, 174, 176 are configured To extend away from the corresponding recesses to seal against surfaces

<p dir="rtl">25 Tightening of threads 180 and retaining nut 182, correspondingly. Unlike the solutions that have been implemented</p>

7787

In advance, this structure eliminates corrosion caused by mounting the seal on a matching component which seals against the valve body hole 178.

Figure 7 is an analog depiction of the insert 106 in the valve design of Fig. 1. In these embodiments the insert 106 defines slots 170 intersecting the outer conical surface 5 108 of the insert 106. The spring 172 is mounted on the insert 106 in each slot 170

It extends from the notch 170 to contact the valve body hole 104 (Figure 1). As shown above, the previously implemented solution configuration, by design, makes the valve body hole 104 the sacrificial member for any wear by the springs 172.

Figure 8 depicts part of the valve 150 (of this technology) in Figure 5, but at a different cross section 10 passing through the bore 170' defined by the surface 190 formed by the valve body 152'. The bore 170' intersects the valve body hole 154' so that it can Mounting the spring 172' in the bore 170' at a fixed and sized end extending from the bore 170' to engage compressively against an outer conical surface 108' of the insert 106' as described above, this technique transfers wear from the valve body hole 154' to Al-Walija 106' is the least expensive and complex.

<p dir="rtl">15 Returning to Figure 5, which depicts the plug valve 150 configured according to embodiments of this technology. An expert in the art would understand this description to mean that this technique transfers wear and tear from the body hole 152 to the outer conical surface of the insert 151. As shown, leakage can occur because the free end of the sealing means 158 wears away from the outer conical surface of the insert 151. In some illustrative embodiments, the remediation procedure may list the details of the reconciliation of estate 151</p>

<p dir="rtl">20 To provide a new sealing surface for the sealing device 158 installed in the body 152. Alternatively, the insert 151 can simply be replaced with a new insert.</p>

In alternative embodiments also a disposable wear member may be located between the outer conical surface of the insert 151 and the body hole 152. For the purpose of this description and the protective elements the disposable wear member may be a disposable liner

<p dir="rtl">25 disposable liner (not pictured) with one surface corresponding to the body hole 152 to function as effectively as the outer conical surface of the insert 151. In some embodiments the inner surface may meet</p>

7787

-11-

The liner is directly opposite the outer conical surface of the insert 151. Alternatively, a sealing device may be provided between the inner surface of the liner and the outer conical surface of the insert. This sealing device may be mounted on the insert and extend to seal against a sealing surface formed by the liner (such as using the insert 106 of FIG. 1), or the sealing device may be mounted on the inner surface

<p dir="rtl">5 of the liner and extends for sealing against a sealing surface formed by the outer surface of the insert.</p>

Returning to another type of flow device suitable for implementing this technique, Figure 9 is a simplified analogue cross-sectional depiction of hydraulic fracturing of the fluid tip 200 configured according to previously implemented solutions. The fluid tip 200 is generally a manifold used to deliver high-pressure corrosive and/or abrasive fluids, ideally used in

<p dir="rtl">10 Hydraulic fracturing processes in the oil and gas industry. There are sealing areas in the fluid end 200 that experience the type of corrosion problems described above in seal valves. Similar to the conventional plug valve 100 depicted in Figure 1, a plurality of components attaches a sealing device to the manifold body 201. Here, again, the wear member is, by design, the body 201 rather than the lower reconciliation component.</p>

<p dir="rtl">15 more complex and less expensive.</p>

For example, body 201 defines a discharge opening 202 in these sealed embodiments by inserting a discharge plug 204 and securing it by advancing a retaining nut 206 into the body 201. The discharge plug 204 supports a sealing device 208 that seals against the hole that defines Discharge port 202. Figure 10 is a simplified depiction

<p dir="rtl">20 A cross-section of the vacuum plug 204 having a surface 205 defining the recess 207 in which the sealing device 208 is mounted at an internal diagonal surface 211 of the diagonal sealing device 208.</p>

In these illustrative embodiments the cavity 207 is a square but the embodiments are not restricted. An expert in the art will understand that the bore configuration 207 is largely determined by whatever shape is required to mount the type of sealing device chosen. The cavity 207 intersects the outer surface

<p dir="rtl">25 215 of the vacuum plug 204, allowing the sealing device 208 to be of a specified size such that it extends</p>

A portion not installed in the recess 207 beyond the outer surface 215 for compressive engagement.

Opposite the hole 209 that defines the discharge hole 202. In this structure, a high-pressure corrosive and/or abrasive fluid can be injected between the sealing device 208 and the hole 209, due to wear on the surface of the sealing device formed by the hole 209. This technique transfers the wear and tear From the body piercing 209 to the less complex and expensive vacuum plug 204. .

<p dir="rtl">5 Fluid end bodies are traditionally made of heat treated carbon steel</p>

heat-treated carbon steel, such that it is not uncommon for the body 201 to crack before any further corrosion of the body to the point of creating a leakage between the vacuum plug 204 and the hole 209. However, advances in technology are introducing a stainless steel body construction body leads to longer operating life. As a result, this wear cannot be neglected but is instead a consideration

<p dir="rtl">10 To reduce wear on the fluid tip structure. A leading source of bore 209 in conventional fluid ends is a sealing device 208 that is installed in the vacuum plug 204 and extends therefrom to seal against a sealing surface formed by the body 201.</p>

Figure 11 is an enlarged cross-sectional depiction of the fluid tip 230 configured according to this technique, in several positions, to transfer wear and tear from the body to the less complex and expensive component.

<p dir="rtl">15 It is tightly fitted to the body. The body of the manifold 232 creates a plurality of interconnected bores, including a discharge hole 234 that creates a discharge hole 235 similar to the discharge hole 202 at the conventional fluid end 200 shown in Figure 9. The term “discharge hole” for the purpose of this description means a surface defining the discharge hole 235 into the discharge plug 236 and the retaining nut 238 is mounted. For clarity, although Figure 11 overlaps the discharge hole 234 that defines</p>

<p dir="rtl">20 An upper end of the discharge opening 235 where the retaining nut 238 is attached, the discharge hole 234 also refers to lower portions of the discharge opening 235 where the discharge plug 236 is secured to the body 232 and where the valve (not depicted) resting on the body 232 is located. In general, for the purpose of this Description The discharge hole 234 forms multi-dimensional diameters at different longitudinal locations of the discharge hole.</p>

<p dir="rtl">25 The discharge opening 235 is sealed closed by inserting the discharge plug 236 into an opening</p>

emptying and holding it in position by introducing the retaining nut 238. as opposed to the plug

The conventional seal 204 in Figure 9, however, does not include a sealing device mounted thereon that seals against the hole 234. Instead, the seal 236 defines the sealing surface 237 for a sealing device (not shown in Figure 11) that is installed in A cavity formed by a surface 239 of the body 232.

<p dir="rtl">5 Figure 12 is a simplified cross-sectional enlargement depicting the structure of a sealing device. Body includes 232</p>

The surface 239 that forms the recess 240 intersects with the discharge hole 234. A sealing device 242 in these embodiments is mounted in the recess 240 to include an outer diagonal surface and thus be supported by the body 232. As stated above, the square, triangular shape of the recess 240 is for illustration and is not restricted to the embodiments. mentioned. Any form necessary to install the required sealing device is stated, where it is

<p dir="rtl">10 The sealing device is flexible, spring, metal, etc. As shown above, the recess 240 intersects the hole 234 which allows the sealing device 242 to be of a specified size such that a portion of the sealing device 242 is not contained in the recess 240 and extends beyond the recess 240 and beyond the hole 234 to seal compactly against the sealing surface 237 (Figure 11) Identified by vacuum plug 236.</p>

The structure of this seal, pictured in Figure 12, transfers corrosion wear from the body to the...

<p dir="rtl">15 Discharge plug. It significantly improves fluid end operations because operations involving the vacuum plug 236 are less complex and less expensive than repairs involving the body 232, ideally including weld-repair. Furthermore, the welded repair body 232 is subjected to prior cracking in the repaired area. Also, longer operating life can be achieved by applying an erosion-resistant surface treatment to seal 236,</p>

<p dir="rtl">20 Such as high velocity oxygen fuel (HVOF) treatment, tungsten carbide coating, carburizing the material, etc. Therefore, replacing rather than repairing a perfectly corroded 236 vacuum plug is therefore beneficial, making it useful for repairing the leaking valve component. According to this technology in the field, the downtime is significantly reduced.</p>

Returning to Figure 11, the body 232 includes a surface 241 that defines the cavity intersecting with the hole

<p dir="rtl">25 234 and is prepared to install the sealing device (not pictured) that extends from the socket to seal against</p>

A sealing surface formed by a discharge valve seat (not shown). Fig

Similarly, body 232 includes a surface 243 that forms another recess intersecting the hole 234 and configured to mount another sealing device (not shown) that is sized to extend from the recess to seal against a sealing surface formed by a suction valve seat (not shown). The multiple references to the same hole 234 are for the purpose of ease of description and not to narrow down the 5 examples mentioned for this technique. Whether these recesses 241, 243 are formed in the same hole or different holes will not modify the perspective of the mentioned models relating to the cavity for installing the sealing device in the body, and the sealing device is installed in the cavity and of the sealing means against the sealing surface of the component in the sealing engagement between them.

Similarly, the suction hole 247 is sealed closed by inserting a 10 suction plug 244 that defines the sealing surface 245 and holds it in position by introducing a retaining nut 246 into the body 232. Again, the body 232 in these illustrative embodiments includes a surface 248 that forms the cavity Intersecting the hole 247 and adapted for installation of the sealing device (not shown) extending from the recess and sealing against the sealing surface 245 of the suction plug 244. This transfers wear from the body 232 to the absorbent seal 244 compared to solutions previously implemented 15 and in accordance with embodiments of this technology.

The body 232 also has a plunger opening 250 of a specified size to receive a tuffing box sleeve 254 that is held in position by providing a retaining nut 256. The opening 250 is partly formed by a hole 252 having a surface 258 defining a recess at the intersection with the hole 252, which The 20 illustrative models are fitted with a clamp (not shown). Although these illustrative models use a diagonal clamp, the models mentioned are not restricted. In alternative embodiments other types of structures using this technique are mentioned that employ axial seals, crush seals, and the like.

Figure 13 is a simplified cross-sectional depiction of the body 232 having a surface 257 on which 25 creates the recess 258. Again, the recess 258 intersects the body hole 252 which allows a portion including an outer diagonal surface for a diagonal sealing device 260 to be installed in the recess 258. The portion extends

Another of the sealing device 260 in the socket 258 of the socket 258 is compressed against the sealing surface 259 of the sleeve 254. Although in these illustrated models a diagonal clamping method is used, according to the mentioned models it is not restricted. An expert in the field will noticeably understand that there are other types of sealing methods that can be used instead of or in addition to

Figure 14 depicts a number of additional recesses in the body 232 for mounting a plurality of sealing devices to transfer wear away from the body 232 to the compatible component in accordance with embodiments of this technology. For example, body 232 includes a surface 266 that defines an intersecting recess with a hole in the body that defines a discharge orifice 235. Consistent with the entire description, this permits the installation of an axial (non-

Figure 15 is a simplified, enlarged depiction of the body 232 having a surface 267 outlining the recess 273 in which the The axial sealing device 268. In these illustrative embodiments the sealing device 268 is configured to extend beyond a hole defining the opening of the vacuum body 235 to seal against the vacuum plug 236 developed downward by means of an advance</p>

Importantly, the structure of the simplified seal depicted in Figure 15 will not be restricted depending on the embodiments mentioned and the perspective of the technology to be protected. In alternative embodiments a radial seal, crush seal, etc. may be used to transfer corrosion wear from the body 232 A crushing component refers to a sealing device structure that acts at least to a certain degree axially and radially.</p>

<p dir="rtl">20 Returning to Figure 14, the object 232 may include other surfaces that create cavities</p>

To install many other sealing devices. For example, surface 270 creates a recess for mounting a seal that is compatible with a sealing surface for a suction cup (not shown), as in Figure 15. In the same way, body 232 may include surfaces 272, 274, 276 that create recesses for mounting a seal that is compatible with sealing. Opposite the sealing surfaces of the stuffing box bushing

To install a seal configured to seal against a suction manifold (not depicted). Common in any case is the seal that creates this technology that transfers seal wear from body 232 to the less complex and costly coupling component attached to body 232.

Figure 16 depicts a stuffing box sleeve 254 (Figure 11) that is inserted into a slot

which extends from this recess and the sealing means against the sealing surface 259 defined by the stuffing box sleeve 254. With the stuffing box sleeve 254 inserted into an air pressure position that is at a specified clearance in the clearance gap between the outside diameter of the stuffing box sleeve 254 and the hole defining the body The plunger hole 235 and between the sealing device 270 and the sealing device 272 at

<p dir="rtl">10 Opposite end of the stuffing box sleeve 254. The air pressure exerts a force that pushes the stuffing box sleeve 254 out of the plunger opening 235, which complicates the manufacturing process and the tightness of the lower end of the stuffing box sleeve 254. A breather opening 274 can be created between this hole. Regulate and comb the circumference over the stuffing box bushing 254 to vent the air pressure.</p>

Figure 16 also depicts the configuration of the conventional seal 272 installed in

Said embodiments can include combinations of the conventional structure and configuration of this technique where other things can be involved. For example, without limitation, it may be advantageous to use the stuffing box bushing 254 illustrated in Figure 16 if it is manufactured or obtained less expensively than providing the in-body recess 232, and if the location of the designated sealing device is not</p>

<p dir="rtl">20 This is not necessary for the overall design to maintain the high-pressure fluid in the flow path.</p>

Figure 16 also depicts the use of a stuffing box bushing 254 that has an open cylindrical shape and is held in position by the advance of the retaining nut 256 (Figure 11). This construction will be for illustration and will not be identified as restrictive to the technique. There are other configurations that may also be used. For example, it will be understood Experts in the field say there is a traditional stuffing box which incorporates a bushing

<p dir="rtl">25 The stuffing box 254 and the retaining nut 256 are, uniformly, in a component which includes a recess to support a sealing device configured to seal against a hole defining the plunger opening body 235.</p>

Other A stuffing box without this recess is used in combination with a seal carrier insert which interfaces with the stuffing box and provides the recess for seal installation. In other embodiments mentioned, the stuffing box sleeve 254 can be modified to a structure that incorporates a cylindrical-shaped stuffing box mated to it and a surface sealing device insert that provides

Returning to Figure 11, the bushing 254 also protects the hole 252 from wear by providing an inner diameter surface 264 against which the stuffing box packing (not shown) is sealed. Where, again, by design it transfers wear from the body 232 The less complex and expensive 254 bushing.

<p dir="rtl">10 In short, this technology refers to a high-pressure fluid flow device</p>

Which is composed of a body defining a flow path, a container mounted on the body, and a means of sealing the body and the container. For the purpose of this description and safeguards, the term “container” means a component attached to the body to provide high-pressure fluid sealing between the body and the container. In some embodiments the valve "container" shown includes moving an optionally positionable component to control fluid flow

<p dir="rtl">15 During the valve, such as the plug shown and other components including but not limited to wedge, clapper pestle, ball, clip, and the like. In some embodiments such as the fluid end embodiments shown a "container" includes components attached to the body opening for sealing such as but not limited to a vacuum plug, suction plug, discharge valve seat, suction valve seat, stuffing box sleeve, discharge flange, suction manifold, and the like. The term “method of sealing” means the structures shown and Eq</p>

<p dir="rtl">20 Which mounts the sealing device to a body rather than a container that meets it to transfer wear compared to previously implemented body-to-container solutions. “Sealing device” does not explicitly include pre-implemented solutions that mount the sealing device to the container extending from it and the sealing device against the body.</p>
