Button type water valve with self-switching-off function during water cut-off

Abstract

A button type water valve with a self-switching-off function during water cut-off comprises a casing as well as a button type switch and a self-locking mechanism which are mounted in the casing, wherein the casing adopts a right-angled bent pipe structure and comprises a vertical pipeline section and a horizontal pipeline section, a port of the horizontal pipeline section is connected with a water inlet nozzle, and a waist part of the vertical pipeline section is connected with a water outlet nozzle; five irregular cavities which are mutually communicated are formed in the casing, a cavity I, a cavity II and a cavity III are formed in the vertical pipeline section of the casing in sequence, and a cavity IV and a cavity V are formed in the horizontal pipeline section of the casing; the button type switch is mounted in a button mounting duct as well as the cavity I, the cavity II and the cavity III; switching on or off is achieve through staggering or meshing of rotor teeth and stator tail teeth; and the self-locking mechanism is mounted in the cavity IV and the cavity V, the water inlet nozzle and the water outlet nozzle are open during normal water supply, and the water inlet nozzle is sealed by the self-locking mechanism during water cut-off. The water valve is compact in structure, simple and convenient to operate, economical and practical; even if a user forgets switching off the water valve during water cut-off, the self-locking mechanism locks the valve, and the self-switching-off function during water absence is performed, and water resource waste is avoided.

Description

technical field [0001] The invention relates to a pipeline equipment, in particular to a push-button self-closing water valve for shutting off water. Background technique [0002] The opening or closing of the water valve currently used is completely manual operation without self-locking function. The existing problem is: in daily life, when the user turns on the water tap and finds that there is no water, he often forgets to turn off the tap. The continuous outflow causes waste of water resources and even damages houses and furniture. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a push-button self-closing water valve with simple structure and reliable performance, so as to overcome the shortcomings of the above-mentioned prior art. [0004] The technical solution adopted by the present invention is: a push-button self-closing water valve for shutting off water, including a shell, a push-button switch and a s...
