Abstract
Disclosed is a self-closing valve for cutting off the water for a civil water service system, belonging to the field of water supplying valves. The utility model mainly comprises a valve body, a handle, a spring, a push rod, a piston, a valve clack, a floater, etc. In the utility model, the handle is tripped, and the push rod jacks up the floater; after pressure relief, the piston drives the valve clack to push, and a valve is opened; after water supply is cut off, the floater automatically falls through the own weight of the floater, the valve clack automatically falls through the own weight of the valve clack, and the self-closing purpose is achieved. The utility model which can simultaneously control a plurality of water faucets and can achieve the purpose of saving water has the advantages of simple structure, convenient operation, and reliable performance.
Description
A kind of self-closing valve under water-supply off for the use of domestic life water system belongs to the water supply valve field.
The domestic life water system mostly adopts stop valve and water nozzle at present.And the function that stop valve and water nozzle can be closed after all not cutting off the water automatically.Forget when therefore some public arena or the Chang Fashengyin of family cut off the water and close water nozzle, just have the phenomenon of metalling run out in a large number, cause waste in case supply water.
The purpose of this utility model is a kind of valve of design, and it can be closed after cutting off the water automatically; Even water nozzle is in the opening state phenomenon of also can not metalling run out when supplying water again.As long as start a self-closing valve under water-supply off, just can normally use by several water nozzles of its control during water.
The used technological scheme of the utility model is:
Between the lower end surface of the middle part of valve body (3) through hole end face and flap (15), sealing gasket (16) is housed, water intake (1) and water outlet (17) are separated.Flap (15), overanxious net (14), piston (13), rubber bowl (11) are housed on sealing gasket (16) successively, between the inner bottom surface of flap (15) top and float (7), flap seal ring (6) are housed; Valve gap (5) is housed on the top of valve body (3), also seals with O-ring seals (4); In the bottom of valve body (3) locknut (22) is housed, rectangular seal (23), spring seat (24), spring (25), spring case (27), the back of the body female (18), pressure pad (19), U-shaped seal ring (20), O-ring seals (21) and push rod (26) and handle (28).And on piston (13), have a moisturizing hole (2); Have on the float (7) on exhaust port (10), the flap (15) and have water inlet (9).Form piston upper chamber (8) piston cavity of resorption (12) respectively at the two ends up and down of rubber bowl (11).When installing and using, move handle (28), pass through push rod (26), after the pressure release, make the pressure of the pressure of piston upper chamber (8) less than piston cavity of resorption (12) with float (7) jack-up, boost because of hydraulic principle makes piston (13) drive flap (15), thereby open valve; The rear valve body (3) of cutting off the water is interior anhydrous, and float (7) and flap (15) fall to respectively on flap seal ring (6) and the sealing gasket (16) automatically by deadweight, thereby reaches the purpose of water-stopping self-closing.
The utility model is simple in structure, and is easy to operate.Through test, reliable performance.
Accompanying drawing 1 is a structure complete section schematic representation of the present utility model, is in the water-stopping self-closing position;
Accompanying drawing 2 is complete section schematic representation of piston (13).
Be described in detail below in conjunction with accompanying drawing.
In the accompanying drawing 1: (1) water intake, (2) moisturizing hole, (3) valve body, (4) O-ring seals, (5) valve gap, (6) flap seal ring, (7) float, (8) piston upper chamber, (9) spilled water hole, (10) weep hole, (11) rubber bowl, (12) piston cavity of resorption, (13) piston, (14) filter screen, (15) flap, (16) sealing gasket, (17) water outlet, (18) back of the body is female, (19) pressure pad, (20) U-shaped seal ring, (21) O-ring seals, (22) locknut, (23) rectangular seal, (24) spring seat, (25) spring, (26) push rod, (27) spring case, (28) handle.
Its working principle is as follows:
Behind the tap water cut-off, anhydrous in the valve body (3), because of anhydrous buoyancy floats (7) and piston (13) flap (15) fell automatically by the deadweight while, fall respectively on flap seal ring (6) and the sealing gasket (16), reach the purpose of closing automatically.Tap water is entered in the valve body (3) by water intake (1) when supplying water, and enters into piston upper chamber (8) by moisturizing hole (2), by float (7) and flap (15) valve is obturaged by the pressure of tap water.Hydraulic pressure is higher, and Feng Deyu is tight.When the needs water, the water of moving handle (28), push rod (26) jack-up float (7), piston upper chamber (8) is by spilled water hole (9) and water outlet (17) quick pressure releasing.Because of moisturizing hole (2) and spilled water hole (9) cross-sectional sizes great disparity, so can make piston upper chamber (8) and piston cavity of resorption (12) form pressure reduction.Under the effect of pressure reduction, piston (13) is boosted, and drives flap (15), thereby opens valve, and tap water just successfully flows to water outlet (17) by water intake (1).
After loosing one's grip, spring (25) automatically resets push rod (26).
Claims (2)
1, a kind of self-closing valve under water-supply off mainly is made up of valve body (3), valve gap (5), handle (28), spring (25), push rod (26), flap (15), piston (13), float (7) etc.It is characterized in that:
A. on piston (13), have moisturizing hole (2);
B. on flap (15), have water inlet (9);
C. between the inner bottom surface of flap (15) top and float (7), flap seal ring (6) is housed;
D. between the lower end surface of valve body (3) middle part through hole end face and flap (15), sealing gasket (16) is housed, water intake (1) and water outlet (17) are separated.
2, self-closing valve under water-supply off according to claim 1 is characterized in that float (7) is to make with the proportion lightweight material littler than water.
