The utility model has the advantages of being simple in structure and convenient in operation, dependable performance forget to close the bad consequence that the water injection well choke caused when can prevent to cut off the water supply.

Description

Self-closed water tap

The utility model is a kind of water pipe shutter, is commonly called as water tap.

At present, because the increase of city water requirement, feedwater is not enough, and the phenomenon of cutting off the water often takes place, and forgets to close water nozzle after cutting off the water, and can cause very big waste when coming water again, if sewerage freely also can not make current advance indoor reaching downstairs, floods the bubble article, causes any property loss.

The purpose of this utility model is to provide a kind of back water nozzle of cutting off the water can automatically water be cut off when coming water again in opened condition, reopens the self-closing water tap that can recover water outlet after closing water nozzle again.

Solution of the present utility model is that a ball storehouse is set between the cut-off device of water nozzle and water intake, interior dress dash ball float, the dash ball float falls when cutting off the water, when coming the water again because water port that the impulse force of water makes ball float withstand on cut-off device is located, block the water port, when closing water nozzle again, the edge, water port pushes back the ball storehouse with ball float, water in the storehouse floats ball float, and open water nozzle and can resume water supply this moment.

The utility model is simple in structure, and is easy to operate, and reliable performance forgets to close the adverse consequences that water nozzle causes in the time of can preventing to cut off the water.

Below in conjunction with accompanying drawing the utility model is specified:

Fig. 1 is the utility model sectional side view;

Fig. 2 is place, the utility model water port vertical view cutaway drawing;

The utility model is by valve body 1, cut-off device 2, water intake 3, water outlet 4 constitutes, have water port 8 on the cut-off device 2, a moon shape locating slot 9 is arranged at the bottom, valve body 1 is fixed with locating stud 10 with month shape locating slot 9 corresponding parts, valve body 1 between cut-off device 2 and the water intake 3 is provided with ball storehouse 5, interior dress dash ball float 6, there is spherical crown shape hole 7 in ball storehouse 5 near 8 places, water port, spherical crown shape hole 7 cooperates with dash ball float 6 sizes, 8 ball storehouse 5 sides have a breach 12 in the water port, water intake 3 places are fixed with resistance spheroid 11, and there is vent hole 13 on 5 tops, ball storehouse, and piston 14 is equipped with at vent hole 13 places.When opening water nozzle, when pipeline is cut off the water, water in the ball storehouse 5 is discharged from water outlet 4 by water port 8, dash ball float 6 falls, and during piped water, water flows into ball storehouses 5 with the dash ball float 6 spherical crown shape hole 7 of rushing to summit from water intake 3, block water port 8, simultaneously the air in the ball storehouse 5 is discharged from vent hole 13, piston 14 can be lived water blocking, can not flow out from vent hole 13.In the time of need discharging water, close cut-off device 2, the sidewall of breach 12 pushes back ball storehouse 5 with dash ball float 6, and the water in the ball storehouse 5 floats dash ball float 6, opens cut-off device 2 again water is flowed out.Month shape locating slot 9 can carry out spacing to cut-off device 2, and the effect of breach 12 is to be in half-open position when cut-off device 2, and dash ball float 6 can enter in the spherical crown shape hole 7, and plugging effect is good, and resistance spheroid 11 can stop dash ball float 6 to enter water intake 3.

Claims (4)
