Abstract

The present invention relates to a kind of water system terminal valve (water tap) that can close automatically.It is to connect movable block by the movable block in valve body, the valve cavity, an end, and the controlling rod that the other end is stretched out by the valve body water outlet constitutes.Be in normally off during nobody control of this valve.Use it for the purpose that public toilet can reach water saving.

Description

Passive normally-closed terminal valve door (water tap)

Closing of existing water system terminal valve (water tap) needs to be operated by the people.Using it for communal bathroom the user is often taken place constantly forgets that throttle down (water tap) causes the phenomenon of water waste.

Be head it off, the present invention proposes a kind of terminal valve (water tap) that is in normally off can close promptly unmanned control automatically the time.

Valve of the present invention (water tap) be by have, hollow valve body, movable block and the controlling rod of water inlet constitute.Movable block is in valve body, and controlling rod one end links to each other with movable block, and the other end stretches out outside the valve body by the water outlet of valve body.It is movable that movable block can be controlled in the valve body by controlling rod, and water outlet is just blocked at the water outlet place of valve body in the unwatched natural stability of movable block position.Constituting between movable block and valve body this moment a kind ofly is enough to stop water from cooperating of passing through therebetween.But in movable block is in valve body during any other position, all having between movable block and valve body is enough to gap that water is passed through.During use, as long as promote movable block away from the water outlet place with controlling rod, water just can be flowed out by water outlet from passing through between movable block and valve body.After the user unclamped controlling rod, movable block was got back to its natural stability position again, blocks the passage of water, thereby reached the purpose of closing automatically.

Valve body of the present invention is applied to the effect that public toilet can reach conserve water owing to can close automatically.

Further specify below in conjunction with drawings and Examples.

Fig. 1, Fig. 2, Fig. 3, Fig. 4 are respectively four embodiments' sketch.

＜1〉is valve body among the figure, has the chamber of a hollow, a water outlet and a water inlet that links to each other with supply channel.＜2〉be the water outlet of valve body.＜3〉be movable block.＜4〉be controlling rod, the user can move movable block by controlling rod and open water outlet.

Among the embodiment of Fig. 1, the water outlet of valve body is a conical bore, and movable block＜3〉is a round platform, and movable block can stop water to pass through in the conical bore of water outlet at ordinary times.During use,, the push lever that makes progress just can allow water to flow out from water outlet as long as disengaging movable block and conical bore.After the user unclamped operating handle, movable block and controlling rod move down together automatically blocked water outlet again.

Among the embodiment of Fig. 2, movable block is a spheroid, and valve body water outlet contacted with it is a taper hole.

Movable block is a spheroid among the embodiment of Fig. 3, and it is a sphere that the valve body water outlet is in contact with it part.

Surface of contact with water outlet and movable block among the embodiment of Fig. 4 is set as the plane, above movable block＜3〉Gai Zaikong＜2 〉.

When valve and movable block are made by hard material, because the influence of machining accuracy may form the gap between its surface of contact.Be head it off, we increase the sealing gasket that a flexible material is made between valve body and movable block.So just can guarantee under the not high situation of machining accuracy, to avoid to leak.

Fig. 5 is the embodiment of this design.

Among the embodiment of Fig. 5, between valve＜1〉and movable block＜3 〉, a sealing gasket＜5〉is arranged.This pad can be fixed on the movable block and also can be fixed on the valve body, becomes the part of movable block or valve body.

When movable block and controlling rod are when being made than light material by proportion, between movable block and valve body, possibly can't form enough contact pressures.We directly or by the controlling rod mounting spring, so just can improve contact pressure between movable block and valve body in order to avoid seepage between valve body and movable block for this reason.

Fig. 6 is an embodiment's of this design a reduced graph.

Among the embodiment of Fig. 6, between valve body＜1〉and movable block＜3 〉, a spring＜6〉is arranged.

The present invention designs for water saving, and it also can be applied to other fluid-duct-system.
