Abstract

The utility model belongs to a water gate particularly an automatic shut tap which is characterized in that a returning rod is arranged in the water inlet of the water gate. The returning rod is sleeved by a rubber pad. A spring is arranged in the front of the rubber pad. A fixing disc which is used to fix the direction of the returning rod is arranged at the back of the rubber pad. One end of the returning rod is against an eccentric cam. A spring is arranged on the upper part of the eccentric cam. The eccentric cam is integrated with a rotating handle. The returning rod is pressed by the pressure of the water to slowly slide on the eccentric cam and slowly turn to one side with small diameter and the position of the returning rod is changed. The returning rod is away from the water inlet to make the water enter. The water gate can be automatically turned off without water to thoroughly solve the problem that the floor is covered by the water after the people go away because the water gate is not turned off without water.

Description

Automatic shut tap

The utility model belongs to water valve, is specially a kind of anhydrous water valve that can close automatically.

At present anhydrously close comparatively varied in the market production and sales of water tap technology and product automatically.For example: the disclosed patent No. of Patent Office of the People's Republic of China: the technological scheme of 92243305.4 titles " the anhydrous water tap of closing automatically " is " handle that can swing and a coupled axle; make seal rubber pad on valve block and the valve block be close to the inner plane swing, utilize frictional force between valve block and valve body inner plane big or small and realize with the gravitational moment of handle deadweight generation ".Its deficiency is that the friction time between valve block and valve body inner plane grown, and the sensitivity of water tap just reduces, and valve just closes not dead, can occur the phenomenon of perennial draingage down.

The purpose of this utility model is to provide a kind of active force by spring to come the real water valve of closing, and is simple in structure, easy to use, can regulate the current size fast arbitrarily when water is arranged, the anhydrous water valve of closing automatically that can close automatically when anhydrous.

The purpose of this utility model is achieved in that in the water intake of water valve body a moving rod, on moving rod, be with a rubber cushion, one spring is arranged before the rubber cushion, after the fixing fixed wafer of moving rod guiding is arranged, moving rod one end withstands on the eccentric cam, one spring is arranged at eccentric cam top, and eccentric cam and rotatable handle are one.

Advantage of the present utility model is: simple in structure, use easy to operate, the size of energy quick adjustment current when water is arranged, can close water valve automatically when anhydrous, it is good to close performance, long service life, fundamentally solved and forgotten when anhydrous and close, the people walks current phenomenon completely, is that family and unit use comparatively desirable water valve.

Fig. 1 is the utility model structural principle generalized section.

1-rotatable handle, 2-waterproof gland, 3-waterproof ring, 4-gland, 5-spring, 6-water intake, 7-moving rod, 8-rubber cushion, 9-fixed wafer, 10-eccentric cam, 11-water valve body.

Below in conjunction with accompanying drawing in detail the utility model most preferred embodiment is described in detail:

One moving rod is arranged in the water intake of water valve body, on moving rod, be with a rubber cushion, a spring is arranged before the rubber cushion, after the fixing fixed wafer of moving rod guiding is arranged, moving rod one end withstands on the eccentric cam, and a spring is arranged at eccentric cam top, and eccentric cam and rotatable handle are one.Water valve is when static, and spring is pushed down moving rod, makes rubber cushion be close to water intake, reaches water-tight when water is arranged.In the top of moving rod an eccentric cam is arranged, when not having water, eccentric cam is automatically brought on the big position of diameter.Moving rod is subjected to the size of the pressure of water, slowly slides on eccentric cam, promptly slowly forwards the little side of diameter to, makes the moving rod shift in position, leaves water intake, so that water inlet.One spring is arranged at the top of eccentric cam, and it makes eccentric cam when being subjected to water pressure, does not change the position, when hydraulic pressure reduced, the spring of moving rod promoted moving rod, and moving rod heads on eccentric cam and slides to static place, it is big that diameter changes, anhydrous in water pipe, the water valve Close All.The utility model can use wide general by material such as stainless steel, cast iron, plastics, copper.

Claims

1, a kind of anhydrous water valve of closing automatically, it is made up of rotatable handle (1), waterproof gland (2), waterproof ring (3), gland (4), spring (5) etc., it is characterized in that: in the water intake (6) of water valve body (11) moving rod (7) is arranged, on moving rod (7), be with a rubber cushion (8), rubber cushion (8) is preceding a spring (5), after the fixing fixed wafer (9) of moving rod (7) guiding is arranged, moving rod (7) one ends withstand on the eccentric cam (10), one spring (5) is arranged at eccentric cam (10) top, and eccentric cam (10) is an one with rotatable handle (1).
