Abstract
A cartridge valve includes a fixed disk 80 and a movable disk mounted in a housing. A lever extends through a major opening axially located at one end of the valve. The lever is attached to a coupler for facilitating movement of the movable disk relative to the fixed disk to control the flow and temperature of water passing through the valve. A flexible valve is attached to the coupler and, in normal use of the valve, prevents holes formed therethrough from communicating with a passage formed through the movable disk. Air from the environment surrounding the valve can enter the major opening, and upon the occurrence of a negative pressure in the water supply, will flex the valve to allow air to enter the supply line to negate the undesirable effects thereof.
Description
The present invention relates to cartridge valve (CARTRIDGE VALVE hereinafter referred cartridge valve), the cartridge valve of using in the tap of an integrated air vacuum breaker is particularly arranged in the valve with vacuum breaker (VACUUM BREAKER).
Cartridge valve is a kind of water flow control valve, and it is by compact a pair of flat substantially hardboard or the dish that is provided with in a housing or outer cover, for example is that pottery and other assemblies form.Each hard disk has a high polish surface, docks joint with the polished surface of another dish.In cover, can move one of in the hard disk with respect to another dish fixing in cover.One bar of cartridge valve has by the outwardly directed part of cover, and reaches the part in the cover.The motion of the exterior portion of bar makes the removable dish in cover rotate and translation with respect to fixed tray.
Usually, a hot water inlet's conduit and a cold water inlet conduit are connected on the outer cover, so that selectively heat supply water and/or cold water.Heat and/or cold water are by being fed in the inlet opening of passing on the fixed tray in the mixing chamber or opening that forms on the polished surface at removable dish.Fixed tray has an outlet, and it selects the location by fixed tray and mixing chamber, to the water channeling conduct, for example, by the nozzle or a shower nozzle of the tap under this cartridge valve of this chamber to one.
Cartridge valve is designed to always, and the opening of this mixing chamber does not pass removable dish, and only is selectively to open to polished surface, the entrance and exit of fixed tray.The high polish surface of removable dish and fixed tray provides tight water-stop, and it defines the passage of water of the mixing chamber of the opening that leads to fixed tray and removable dish.
The cartridge valve of the above-mentioned type usually since its element closely overlapping and sealing is within it and volume compact in cover.Since coming out, this valve in many years, once individual component had been carried out modification.But, because the characteristic of this cartridge valve compactness and the confined space that is had in the tap of this valve is installed was seldom carried out modification to removable and fixed tray.Therefore continue to use, fixed tray is formed with through hole always, and removable dish is formed with the opening that does not pass this dish always, as previously discussed.
When tap device comprises a shower nozzle, it or with nozzle independently or among nozzle, water can selectively be guided nozzle or shower nozzle into.Usually in the kitchen in room, use shower nozzle; Do the wash items such as dish, jar, dish, cutter.These parts that will wash are put into sink, put into water and washing agent in the pond, are used for washing.Generally from being washed on the part detergent water is flushed to the sink with shower nozzle.Gradually, the water in the pond is owing to the swill under the bowl dishwashing becomes dirty.
When using the shower nozzle flushing to be washed part, do the wash the people and often shower nozzle is put into sewage when working, thereby clean water is entered in the Chi Zhongshui by shower nozzle.
It is unexpected that pressure drop might take place and be referred to as " negative pressure " sometimes in the hydraulic pressure of supplying with to valve.At this moment, the relative pressure in the pond between sewage and the water purification that enters is put upside down, so that this negative pressure is taken out sewage or siphon enters into shower nozzle.For example, because near supply mains break, perhaps this pressure drop can take place from the fire extinguishing of drawing water of local fire-prevention pipe in the fire personnel.Because this refluence, sewage is drawn into shower nozzle, can enter entry conductor and mixes with indoor potable water by valve, and these sewage can occur again when using indoor other leading.
