Definitions

  • the invention relates to a valve device for a sanitary valve with diaphragm valves designed as mass regulator valves.
  • Diaphragm valves are valves in which the valve closing body has a diaphragm, wherein in the present case a diaphragm valve type is used, which is controlled by a pilot valve.
  • the pilot valve By opening the pilot valve, the diaphragm valve opens under the pressure of the flowing water, and to close the diaphragm valve is also only the effort to schl plexen the pilot valve erforderl I, since the actual closing process then again by the water pressure. Therefore, diaphragm valves have the great advantage that they require a low operating cost. For this reason, they are usually applied to electrically operated valves. Usually these diaphragm valves are only used for switching on and off.
  • An electrically operated diaphragm valve is already known in which the control bore of the diaphragm valve can be opened and closed by means of an electric drive.
  • the maximum stroke of the membrane, d. H . the size of the open position is limited by a stop which can be changed independently of the switching on and off of the valve with the aid of a tool, namely a screwdriver, in its position (EP 0 253 948 B1).
  • the invention is based on the object to provide a valve device of the type mentioned, with the temperature of the regulated by the valve water flow can be adjusted by the mixing ratio between hot and cold water with very little effort.
  • the invention proposes a valve device with the features mentioned in claim 1. Further developments of the invention are the subject of dependent claims.
  • the valve device includes a water guide, which leads from a cold water inlet via a diaphragm valve to a cold water outlet. It also contains a second water supply that leads from a hot water inlet via a diaphragm valve to a hot water outlet. Both diaphragm valves are designed as volume control valves. For this purpose, the control body of an associated pilot not only move between a closed and a fully open position, but can take tincte positions between the two end positions. The membrane thus follows the movement of the control body. In this way, you can adjust a bel ble mixing ratio between the hot and the cold water.
  • the outlets of both diaphragm valves must be in a common mixing water outlet. This can be located inside or outside of a valve body of the valve device.
  • To set the mixing ratio is a control device for the pilot valves, with which the mixing ratio can be adjusted.
  • a common valve closing body is provided for both diaphragm valves, which serves as a control body for the pilot valves of both diaphragm valves.
  • it can in particular be movable in opposite directions, so that it is moved when opening the one pilot valve in the direction of the closure of the respective other pilot valve. In this way, it is possible with simple means to change the mixing ratio of the two water passages by one operation.
  • the two diaphragm valves each have their own Ventilschl intevaluation or control body, wherein the two control body dan NEN preferably be moved together by a common control device NEN.
  • the two control bodies can be held together by a device of the control device and thereby moved together.
  • control device is a mechanical control device. Because of the small amount of torque required for actuation, even very small or narrow handles can be used for this purpose.
  • the movement of the control body or in the case of two control bodies of both control bodies is in each case a straight-line movement.
  • the two diaphragm valves are symmetrical to each other angeord net, especially if they, as the invention also suggests, are identical.
  • a rotatable shaft which is provided outside of the housing of the sanitary faucet with a rotary handle, attack by means of an eccentric or a cam on a control body or possibly on two control bodies to the Versch shift.
  • the two diaphragm valves are arranged mirror-inverted and the control body is mounted reciprocatingly movable between them.
  • the control device is designed such that it can move both control bodies or optionally the two opposite ends of a multi-part control body such that a closure of both control openings of the diaphragm valves is possible.
  • the arrangement of two diaphragm valves operatively connected in parallel can also serve as a shut-off valve.
  • two parts of a control piston can be guided telescopically into one another so that they can be moved together on the one hand, but also on the other hand in different directions.
  • One movement could be effected by one eccentric while the other movement could be effected by a wedge.
  • a valve device that can be used both for switching on and off as well as Tem peraturregelu ng. This can also be done by moving a single actuator in different directions.
  • control piston or pistons can be effected via eccentrics, via a wedge slide, via a toothed wheel, a thread, a Bowden cable, via spindle, fine thread, lever or the like.
  • control device has a temperature sensor, in particular a Deh nscherlement, ie, an element which is exposed to the temperature of the mixed water and in response to the temperature of the mixed water performs a movement that dan n acts directly or indirectly on the control piston.
  • a thermostatic valve can be realized, which also has the advantage that it is very easy to serve.
  • a valve device for a sanitary valve can then be realized in which the opening or closing of the valve and a quantity regulation are carried out manually with the least expenditure of force, while the temperature adjustment is effected by a dehens element.
  • Figure 1 is a schematic section through a valve device according to the invention.
  • FIG. 2 shows the view of the valve device of FIG. 1 from below in FIG. 1; 3 shows a perspective broken view of the valve device of Figure 1.
  • FIG. 1 shows in a common body 1 of a sanitary fitting a valve device with two diaphragm valves.
  • FIG. 1 shows a water inlet 2 for cold water, which leads to a first membrane valve 3.
  • This diaphragm valve 3 has an annular valve seat 4, downstream of which an associated Wassertechnologyu ng leads to an outlet 5 for cold water.
  • This cold water supply to the outlet 5 is formed in within the annular valve seat 4.
  • an annular space 6 is formed, which is in communication with the inlet 2.
  • On the valve seat 4 is a Ventilschl inteskomati restructuring 7, which has in its resting on the valve seat 4 area a support 8 made of elastomeric material.
  • a membrane 9 which forms a U-shaped fold.
  • the outer leg of this membrane 9 is firmly and tightly connected to the body 1 of the sanitary fitting.
  • the membrane 9 takes over the seal between the Ventilschl intesuperspharmonics 7 and the body 1 of the sanitary fitting.
  • a pressure chamber 1 0 is formed on the side facing away from the valve seat 4 of the valve closing body 7. From the upstream of the diaphragm valve arranged annular space 6 performs a balancing bore 1 1 through the valve body 7 through and mü ndet on the back of Ventilschl intements 7, ie in the pressure chamber 1 0th
  • the support 8 made of elastomeric material, which is net angeord net on the front of Ventilschitzkör- 7, may be integral part of the membrane 9.
  • a control bore 1 2 leads from the pressure chamber 10 into the water supply downstream of the diaphragm valve.
  • a second diaphragm valve constructed in mirror-inverted fashion, is arranged, which is arranged in a warm water supply, which leads from an inlet 22 for warm water to an outlet 25 for warm water.
  • a control body 14 is arranged, which is l inear slidably. It is sealed in the body 1 by means of seals. Its two ends have a coating 1 5 also made of elastomeric material. These two ends are a respective mouth of the control bores 1 2 in the respective pressure chamber 1 0, 20 opposite.
  • the control body 14 together with the respective control bore 1 2 each forms a pilot valve for the two diaphragm valves. In the illustrated position, the opening into the respective pressure chamber 1 0, 20 Steuerbohru ning 1 2 are open. If water passes through the inlet 20 or 22 to the inlet side of the respective membrane diaphragm, the water enters the pressure chamber 10, 20 through the respective balancing bore 11.
  • the water flows through the open Steuererbohru ng 1 2 through to m outlet. Since there is no pressure on the downstream side of the respective valve closing body 7, the inflowing water lifts the valve closing body 7 away from the valve seat 4. The valve opens. When both cold and hot water enters, both valves are opened. The opening movement goes so far until the mouth of the respective Steuererbohru ng 1 2 is positioned so close to the end of the control body 14, that there is only a very small amount of water through the Steuerbohru ng 1 2 flows out.
  • the control body 14 has the shape of a spindle with a plurality of circumferential grooves.
  • a peripheral seal 1 6 is arranged in a further groove, which represents a further improvement of the seal.

  • the shaft 1 7 contains an eccentrically mounted eccentric pin 1 9, which engages in the groove of the control body 14.
  • the left is opened further when closing the right valve and vice versa. Therefore, with the illustrated valve, the ratio between the hot and the cold water is set, so a mixture between the two temperatures.
  • FIG. 2 shows the two inlets for cold water 2 and for warm water 22 and the two outlets 5 and 25 for the cold and warm water. Only behind these two outlet openings 5, 25 is a merging of the two water flows and thus a mixture.
  • FIG. 3 shows again the way in which the eccentric pin 19 engages in the groove of the control body 14.

Abstract

L'invention concerne un dispositif à soupapes pour valve sanitaire, comprenant deux conduits d'écoulement (2,5;22,25) de conception sensiblement identique, lesdits conduits d'écoulement reliant respectivement une entrée à une sortie. Chaque conduit d'écoulement abrite une soupape à diaphragme. La soupape à diaphragme est conçue de manière à fonctionner comme soupape régulatrice de débit. Une convergence des flux d'eau régulés en termes de débit peut avoir lieu en aval des deux conduits d'écoulement. Un dispositif de commande assure le déplacement d'un corps obturateur de soupapes pilotes (12,14) des deux soupapes à diaphragme. On peut obtenir un mitigeur en réduisant la distance entre le corps obturateur de la soupape pilote de l'une des soupapes à diaphragme et un orifice de commande associé de cette soupape à diaphragme tout en augmentant la distance correspondante de l'autre soupape à diaphragme.
