Abstract

The utility model relates to a water-saving automatic switch, comprising a valve body in which a valve plunger shaft fixedly connected with a piston shaft is arranged. A sealing ring is arranged on a convex table positioned at the front end of the plunger shaft. The outer part of a piston is provided with a reset spring. The lower end of the piston shaft is provided with a connecting sleeve, and a pedal switch is connected with the piston shaft with the connecting sleeve. The late-model device can avoid various pollutions which are caused because a tap is contacted by hands, can solve the problems existing in various existing water-saving switches that action is not flexible, and structure is complicated, and can be widely used in hospitals, especially contagious disease hospitals and other public places.

Description

The water saving recloser

The utility model relates to a kind of Water-saving valve.

Pass through the screw mechanism control switch between present widely used running water switch valve body and the valve rod, wearing and tearing are bigger in the using process, seal and also badly also easily leak, the switch that has spring follows the string owing to spring easily gets rusty in the water of being everlasting, cause and reduce the problem of wasting water again working life, in order to address this problem, people have done multiple effort, the technology that one key name is called " single-pass Water-saving valve valve " is disclosed for No. 89202009 as Chinese patent, introduced a kind of by valve body, plunger, the valve that spring is formed, its plunger one end is equipped with sealing gasket, one annular groove is arranged in the middle of the plunger, O-ring seals is housed in the groove, the plunger the other end is equipped with spring, valve inleting water mouth and water outlet, plunger meets at right angles, and the valve seal end is equipped with a nut, this novel device sealing is reliable, easy to use, the deficiency of existence is that operation is dumb, and working life is short.

Task of the present utility model is: overcome the deficiencies in the prior art, design a kind of simple in structure, easy to use, the water saving recloser that water-saving result is good.

Task of the present utility model realizes as follows: it has a valve body water saving recloser, valve plunger axle and piston shaft are housed in the valve body to be connected, on the boss of plunger axis front end seal ring is housed, the piston shaft front boss is equipped with Returnning spring down and between the valve body gland, has a connecting sleeve that foot switch and piston shaft are fused in the piston shaft lower end.

The utility model is because the foot-operated mode of employing is carried out the switch of tap water, the therefore various pollutions that can avoid hand water contacting tap to cause; Owing to adopt foot treadle and flexible cord lacing wire control switch, and adopt spring reset, so flexible movements are reliable.

Fig. 1 is the utility model front section view;

Fig. 2 is the utility model installment state view;

Fig. 3 is the foot switch left view.

A most preferred embodiment of the present utility model, as figure, it has a valve body 1 the water saving recloser, it has water intake and water outlet, valve plunger axle 2 is housed in the valve body to be connected with piston shaft 7, seal ring 3 is housed on the boss of plunger axis front end, under piston shaft outer plunger axle front boss and between the valve body gland 6 Returnning spring 5 is housed, be integral by being threaded between valve line pressure lid and the valve body, a connecting sleeve 8 is arranged in the piston shaft lower end, the lower end of piston shaft 7 is fixed by an end of fixing bolt and flexible cord lacing wire 10, one end of the other end of flexible cord lacing wire and foot switch 11 fuses, connecting sleeve fuses by screw thread and valve body gland, is connected with the outer sleeve of flexible cord lacing wire by bolt 9 in the lower end of connecting sleeve 8.Foot switch has automatic chucking pin button 12, shown in Fig. 1,3, when the long-time water of needs, pins foot treadle with this switch and replaces people's pin to step on.
