Abstract
Disclosed is a valve which can automatically close when tap water is cut off. The utility model mainly comprises a corrugated tube (4), a valve rod (3), a valve clack (7), a valve seat (8), a valve body (5), a valve cover (2), and a screw nut (9) whose outer diameter is provided with a cuneate throughflow slot. During work, the corrugated tube (4) is compressed by the pressure of the tap water, the valve clack (7) is opened, and the tap water flows out. When the tap water is cut off, by means of the elastic force of the corrugated tube (4), the valve clack (7) is combined with the valve seat (8). The utility model realizes self closing when water supply is cut off, controls the phenomenon that the valve leaks, and achieves the purpose of saving water.
Description
The self-closing valve under water-supply off that the utility model relates to is a kind of water saving fixtures.Be applicable to a kind of self closing stop valve that to close the water route when water supply pipe is cut off the water automatically particularly.
At present,, the phenomenon of cutting off the water often occurs, cut off the water at every turn, make people be easy to forget to close water nozzle, when water flowing again, cause the wasting phenomena of metalling run out, cause difficulty for resident's daily life owing to many reasons cause various places water service deficiency.
The purpose of this utility model provides a kind of pressure of water that utilizes and opens and keep the normal open in water route, the self-closing valve under water-supply off of closing automatically when cutting off the water.
Be particular content of the present utility model and most preferred embodiment below: as shown in drawings, the utility model mainly is made up of by the nut (9) that flap (7), valve seat (8), external diameter have the through-flow groove of wedge shape pull-button (1), valve gap (2), valve rod (3), rubber corrugated pipe (4), steel-wire carcass (5), valve body (6), rubber.Rubber corrugated pipe (4), rubber are equipped with by flap (7) in the lower end of valve rod (3), are anchored on valve rod (3) by nut (9).Valve rod (3) upper end is equipped with valve gap (2) and is drawn and turn round (1), by the screw thread on the valve gap (2) rubber corrugated pipe (4) is anchored on valve body (6).The steel-wire carcass (5) of ring seal is housed in the rubber corrugated pipe, and rubber combines with valve seat (8) under the elastic force effect of rubber corrugated pipe (4) by flap (7), in order to throttle down.Working principle of the present utility model is:
By pull-button (1) with valve rod (3) to top offset, then rubber breaks away from valve seat (8) tap water this moment and is entered by the C place by flap (7), by the B place, is flowed out by the D place.By the hydraulics Bernoulli's therem as can be known, the kinetic pressure that produces when tap water flows, static pressure, can overcome pull-button (1), valve rod (3), rubber by flap (7), the gravity of nut (8) and the elastic force of rubber corrugated pipe (4), rubber is upwards held up by flap (7), keep the opening state of tap water pipe line.When throttle down, pull-button (1) to be pressed, rubber, combines with valve seat 8, then valve closing under the elastic force effect of elevation head and how much pressure heads of waterpower and rubber corrugated pipe (4) by flap (7).When tap water pipe line cut off the water suddenly or the anhydrous Open valve of pipeline after, then rubber ends flap (7) under the elastic force effect of rubber corrugated pipe (4), rubber combines with valve seat (8) by flap (7), then valve is closed voluntarily, thereby realized running water valve under the situation of cutting off the water, the function of closing automatically.
Shown in accompanying drawing, the external diameter of nut (9) and valve seat (8) endoporus are slidingly matched, nut (9) external diameter is arranged the through-flow groove of wedge shape that several progressively strengthen from top to bottom simultaneously, when tap water pressure becomes big, valve rod (3) upwards displacement amount strengthens automatically, nut (9) also moves up synchronously with valve rod, and the passage section of the through-flow groove of wedge shape on the nut (9) is increased, and then the flow of water also increases thereupon.On the contrary, during the tap water pressure step-down, nut (9) reduces to top offset with valve rod, and then the flow area of the through-flow groove of wedge shape on the nut (9) also reduces, and the flow of tap water also reduces thereupon.Thereby realized regulating automatically the flow of water with tap water pressure.The utility model at tap water pressure more than 0.01MPa, can normal water supply.The effect of steel-wire carcass (5) is when acting on the rubber corrugated pipe external diameter at tap water pressure, when keeping on the rubber ripple external diameter, keeps the elasticity of rubber corrugated pipe, does not produce conquassation and loses efficacy.
Advantage of the present utility model: the utility model can make when cutting off the water valve close voluntarily, prevents the phenomenon of metalling run out, and the utility model can be realized regulating the flow of water with tap water voluntarily at pressure, and (0.01MPa) valve also can be worked when tap water pressure is low.The utility model can be contained on the water pipe as common water meter, the several water taps of valve may command.Also can make the form of self-closed water tap.
