anik Sanitary water valve with Betätigungsiaec

D escription

The invention relates to a sanitary water valve with a panel of three superimposed control disc and a Gehiiuse enclosed Steuer¬ element, wherein the lower and upper Steuerscheibo fixed and the average control disk is movable relative to the fixed control disks over an attacking her Bctütigungsorgan wherein the tilt in the housing in two planes or ange¬ pivotally disposed actuator the cover and the upper fixed plate cam has been upheld.

A water valve with the aforementioned features is described in DE-OS 35 25 053.4; this hydrogen peroxide solution has as a special feature a valve consisting of three discs control on whose central disc relatively displaceable as a movable control disk relative to the two outer fixed control discs

is. The displacement of the middle Steuerscheibeund thereby regulating the flow of water is made through an actuating member, which engages in the central control disk and connected thereto and to both the lid of the control housing enclosing and the upper fixed control disk in each case one correspondingly positioned aperture extends through , In the beknnnlcn Wαssorvcnlil which is supported [JcläLirjuncjsorrjan lying by a trained him and refraction in the Durch¬ the upper fixed plate cam spherical expansion.

This has the disadvantage that due to the cramped dimensions of the upper fixed plate cam only a very small radius can be designed for the male of the upper control disc bearing ball. The associated narrow Fertigungs¬ tolerances are but in mass production of large quantities of water valves barely observed, and additionally available in the event a small sphere radius bearing surfaces for the actuator in the upper disk are so tight that hardly sufficient stability of the storage of the Betätigungs¬ organs results in the top pane and the leadership of the central movable plate on the actuator.

With a view to avoiding such drawbacks, it is known for example from DE-OS 34 19 208, wherein a comprehensive two discs valve in which the actuating member acts on the upper movable plate, the actuator with a bearing ball comparatively large diameter in the corresponding storing highly trained cover part of the housing. Such a solution, however, is to develop a generic water valve not applicable, because due to the zusätz¬ union third control disk and at a correspondingly thick formation of the housing cover for receiving a bearing ball of larger diameter, the height of the valve as a whole would exceed the beneficial measure.

The invention is therefore based on the object to improve a water valve with the aforementioned features such that its height 1eichzeitig simple to produce at a and is limited in its l unction wirkungs¬ full storage of the actuator.

The realization of this object, including advantageous embodiments and further developments of the content of the patent claims that this description prefixed.

The invention is based on the fundamental idea that the actuating member is mounted on the control element is arranged outside the housing enclosing bearing points such that the fulcrum of the Betätigungs¬ organ lies in the plane of the housing cover. Hereby the significant advantage, in that one part of the cover of the control housing enclosing can be kept relatively thin because it featured no bearing function, but only a Durchtritts¬ has to fulfill for the actuator; on the other hand results in an advantageous manner, a short-sized distance between the arranged in the plane of the housing cover pivot of the Betätigungs¬ organs and its connection to the movable disk, with the result that due to the so-formed short lever arm between the pivot point and point to the central disc and the longer lever arm between the pivot point and the formed at the upper end of Betätigungs¬ organs handle a larger pivoting weguπg the hand lever only to a comparatively small displacement the movable disc executes, so that a fine adjustment of the water way is possible. Therefore, this aspect is in the generic valve is of great importance, since due to the possible in two levels of water outlets of the hydrogen peroxide solution flow through the valve is very much greater than for a two-disc valve, so that even comparably small displacements of the movable control disc as large impact on the total valve have water percolating through.

According to a preferred embodiment is seen vorge that uplifting spherical segment-shaped bearing points is arranged on the housing cover, which are encompassed by a related actuator sleeve positive fit such that a bearing of the actuator on the ausge¬ him formed sleeve in interaction with the on the Gehäuse¬ cover arranged bearing points results. According to an embodiment of the invention, this Lager¬ as a semi-cylindrical bodies are filters formed, which is placed with its sectional area perpendicular to the pivoting plane of the actuating member on the lid of the housing and having an opening for the passage of Betätigungs¬ organs; this fits the sleeve has the half cylinder cross-curricular approaches, so that here verwirk¬ a sliding mounting on a cylindrical section is light. According to one embodiment of the invention, the actuating member in the plane of the housing cover a the passage opening through the housing cover filling spherical thickening which forms a zu¬ additional guiding and securing the actuator against tensile load; but these spherical thickening has no bearing function for the actuator.

After the invention may further be provided with the actuator sleeve by a set on the housing holding member to secure, so that the actuator is fixed with respect to the sleeve bearings.

In the drawing two embodiments of the invention are shown, which are described below. Show it:

FIG. 1 is a sanitary water valve on average,

FIG. 2, another embodiment of the hydrogen peroxide solution valve of Figure 1.

The water valve 10 comprises a control element 11 to an existing three individual discs disc package, which is closed by a housing 12 having a bottom 13, a side wall 14 and a lid 15 um¬. The lower disk 16 of the control element 11 is fixed against the housing bottom 12 and has openings 17 for the passage of hot and cold water on which flows via correspondingly assigned passage openings 18 in the housing floor 13 in the valve; in the figures only one opening 17, 18 is respectively recognized. Set against the top cover 15, the upper plate 19 of the control element 11, which the apertures 17, 18 assigned Um1onkknm ren 20 comprises; between the fixed disks 16, 19, the movable plate 21 with correspondingly communicating Öffnunge arranged n 22, as is apparent from the Figurendar¬ position. In the figures, the valve is located respectively in the open position, is wherein the right edge of the movable disc relative to the associated edges of the fixed disks 16, 19 ver¬ advanced so that the inflowing from below into the hydrogen peroxide solution valve 10 water over the openings 17 and the opening 22 and the deflection chamber 20 can flow into the water chamber of the valve. When the movable plate 21 is moved to the right until the disc edges reach to cover, the closed position of the water valve is reached, in which the guide chambers 20 are constantly under the pressure of pending on the valve water.

To the movement and displacement of the movable disk 21 is an actuator 23 is provided, which the housing cover 15 in an opening 24 and the upper fixed plate 19 in an associated aperture

25 and engages with a spherical guide

26 engages with the movable disc 21 which has for this purpose a bore 28 into which a sleeve 27 is inserted for receiving the ball-shaped guide 26 of the actuating member 23rd The Be¬ tätigungsorgan 23 is essential stabför ig formed with a smaller diameter in the area of ​​Be¬ Durchgriffsöffπungen 24, 25 in the located in the fixed upper plate 19 and the housing cover 15 and a larger diameter outside the housing 12 range. The upper plate 19 is against still surrounding the underside of the housing cover 15 by means of the corresponding passage opening 25

Gasket sealed 29, so that out of the water space of the valve via the interface between control
