Abstract

The utility model relates to a self-closed valve for stopping water, which is provided with a lever, a closed valve, a transparent press cover, and a sealing ring on an original water tap. The utility model has the functions that after tap water is cut off, the water tap is opened, and nobody is not on the spot, the tap water is supplied again, and the water tap can automatically close for saving the tap water, and the utility model can also effectively avoid various kinds of loss caused by the arbitrary flow of the tap water when nobody is not on the spot.

Description

Self-closed valve for stopping water

The utility model relates to a kind of water tap, the Self closing valve of cutting off the water that water tap cuts out automatically.

Employed water tap in the prior art, all be by manually turning on (or closing), make water flow out (or stopping), this water tap is running into when cutting off the water, generally speaking, people turn on water tap and wait water, but when going out, people then often forget and turn off water tap, when water comes, since indoor unmanned, then allow water-white pour off in vain.

The purpose of this utility model is to provide a kind of Self closing valve of cutting off the water that water tap is closed automatically.

To achieve these goals, the utility model has been laid the Self closing valve of cutting off the water in original water tap, promptly work as the interior flowing water of water supply pipe just often, Self closing valve floats under buoyancy function automatically, water tap after make improving is the same with ordinary faucet, and water can flow out when turning on, when cutting off the water owing to anhydrous in the water supply pipe, Self closing valve falls (under action of gravity), has blocked the water outlet of pipeline.When coming water again,, make water not flow out because Self closing valve has been blocked pipeline, and have the pressure at two ends of water end (W.E.) and no water end (W.E.) not wait this moment in the pipeline, stifled tight more of Self closing valve when current are violent more, like this with regard to having guaranteed to come water again the people not situation under, water tap is in closed condition.At this moment, water flows out again if desired, then water tap is screwed to closed condition again, make the lever in the water tap rotate, Self closing valve backed down that at this moment the water of the other end then can flow to no water end (W.E.) in the pipeline, at this moment because hydraulic pressure is equal substantially at the pipe two ends, Self closing valve floats again automatically, and when turning on water tap again, then water can flow out again.

Adopt the water tap of this band Self closing valve, can play water saving effect, supply falls short of demand at China's tap water, the outstanding area of imbalance between supply and demand, often cut off the water location, tall building and water use peak, owing to reasons such as hydraulic pressure, water source, maintenances, often run into and open valve because of cutting off the water, cutting off the water supply and forget and close, come the water people not loss of the water that causes waste at the scene again midway, also may cause the accident, make this nervous water imbalance between supply and demand aggravation.Adopt the design's structure, people can use tap water safe, relieved, frugally.The utility model also can be used for other liquid conducting pipes such as oil, chemical industry.

Be illustrated below in conjunction with specific embodiment:

Fig. 1 is the work schematic representation when in the water tap water being arranged;

Fig. 2 is the work schematic representation when cutting off the water supply in the water tap;

Fig. 3 is the A-A sectional drawing of Fig. 1;

Self closing valve as shown in the figure (3) has been floated by water when Fig. 1 position, makes water (5) can normally pass through pipeline, and Self closing valve (3) employing rubber or plastic materials are made and reached floaty purpose.Position when the Self closing valve position during Fig. 2 is anhydrous free fall reaches the purpose that when coming water again water can not be flow through.Axle (7) is installed on the body (4), passing body (4) and lever (6) seals axle (7) and body (4) then with glue, lever (6) and axle (7) are movingly, be fixed in the water tap by axle (7), lever (6) should guarantee when installing that B holds weight to hold greater than A, it is sagging to make it when free position the B end, when tightening faucet handle (9), valve (8) moves down, make lever (6) rotate around axle (7), this moment, the B end lifted slightly, made the B end contact with Self closing valve (3), because the effect of frictional force, the B end can be with the slight jack-up of Self closing valve (3), Self closing valve (3) forms the slit with pipeline, and water flows out from the slit, and at this moment Self closing valve (3) is again at buoyancy of water effect float downward; (4) be faucet body, (2) are transparent gland, and (1) is sealing cover.

Claims (2)

1, a kind of Self closing valve of cutting off the water is characterized in that: lay Self closing valve on water tap, and be stamped transparent cover, the centre accompanies seal ring; Be equipped with the starting lever in the Self closing valve front.

2, the Self closing valve of cutting off the water according to claim 1 is characterized in that the material that Self closing valve is selected rubber or foamed plastics for use or can be floated by water.
