Title:
LABOUR-SAVING BUTTON WATER-SAVING VALVE
Document Type and Number:
WIPO Patent Application WO/2019/100206
Kind Code:
A1
Abstract:
Disclosed is a labour-saving button water-saving valve, comprising a button (3), a valve core (2), a valve core spring (7) and a valve seat (15), wherein the middle of the valve seat forms a core chamber (14), and the peripheral wall of the core chamber is provided with a water intake hole (12) and a water outlet hole (13); the valve core can be movably inserted back and forth in the core chamber, and has a front end thereof abutting the valve core spring and a rear end thereof being connected to the button; the valve core can move back and forth in the core chamber under the drive of the button and the elastic force of the valve core spring such that the water intake hole and the water outlet hole are in communication or are cut off, thus realising the opening or closing of the water-regulating valve; and an outer peripheral face of a front end of the valve core forms an annular groove (21), the button drives the valve core to move to a cut-off position of the water intake hole and the water outlet hole, such that the annular groove of the valve core is in communication with the water intake hole, and an annular water pressure chamber is formed between the valve core and a peripheral wall of the core chamber. The annular water pressure chamber formed by the annular groove can lower the water pressure sustained by the valve core, realising smooth opening and closing in switching water channel, and avoiding wear on the valve core to improve the service life and sealing performance of the water-saving valve.
