Description

The press-down type water conserving tap

Technical field

The utility model relates to a kind of press-down type water conserving tap, belongs to the valve of water supply pipe.

Background technique

Conserve water resource, saving power are the present big matters of utmost importance of China.The water tap of family and public place use at present, water flow is grasped by the people oneself of water.Because the scarcity of water resources, the problem of water saving is more and more serious.And the general water tap that adopts at communal bathroom, water waste is bigger, and switch is on the point of numerous easy damage.Someone examines and has done calculating, the communal bathroom people when washing one's hands, usually be open the flushing of valve water, soap, both hands are rubbed Xian with the hands then, flushing approximately needs about one minute time again, throttle down not in whole process, even after having the people to wash one's hands not closing valve just leave, cause a large amount of water gurgle the passage situation happen occasionally.With holding the washing face in hands, the loss of tap water is more than 60% for another example.Adopt the electronic induction water tap just can save a lot, but be not to greatest extent, still also have when often hand leaves and run off, and should need ABAP Adapter by tap, spread to family and communal bathroom not quite easily.

Summary of the invention

The purpose of this utility model is exactly in order to overcome the deficiency that prior art exists, a kind of press-down type water conserving tap to be provided, during with hand down pressure arm, valve open water just flows out, hand one leaves, and closes at return spring effect lower valve, has so just reached the purpose of real conserve water.Adopt this tap, the restricted easily saving of forming device condition.

Above-mentioned purpose is achieved in that the press-down type water conserving tap, comprise valve seat, spool, spool one end is set in the valve seat through-hole, end band tooth valve shaft inserts in the spool from the valve seat opposite side, with the spool Spielpassung, the three uses bolton, the band internal tooth return arm of couple and valve shaft engagement, return is closed spring one end and is penetrated the return of fixedlying connected with valve seat and close in the through hole of spring fixed support top, the other end is stuck in the recess of the return arm of couple, the band internal tooth presses down opens the arm of force and valve shaft engagement, the waterproof cover screw is connected with valve shaft, symmetry has through hole on the spool, the movable inner core of 8 font covering of the fans is equipped with in the through hole, center, covering of the fan two ends is arranged with the blind groove of spill, the boss clamping of stretching out downwards on blind groove and the valve shaft, 90 ° of fixedly inner cores that are arranged with pair of projections and fan-shaped slotted eye are close to movable inner core each other, groove on boss and the spool the other end madial wall is pegged graft, the fixing movable inner core vertical interlaced of fan-shaped slotted eye on the inner core and 8 font covering of the fans, the spool lower end is fixed inner core with the sealing cover of band through hole, and spool is threaded with the pipeline depotition cock.

This press-down type water conserving tap, novel in design, be skillfully constructed, Mechanical Reliability is fabulous, maintenance, replacing are conveniently, the product cost is low, and using scope is wide, and it is various with on the drainage facility except being used for family, also can be used on the various sanitary fittingss of public place, comprise that male sex's urinal etc. locates can realize flushing with the foot pedal opening arm of force 6.Really realized water-saving purpose.Fixedly inner core and movable inner core adopt stupalith, and long service life is opened number and reached more than ten thousand times.
