Abstract

The invention discloses a mechanical water-break automatic close valve. In the mechanical water-break automatic close valve, the functions of controlling the on-off state and the water-break self-closing of water are achieved by utilizing the change of tap water pressure with water or without water, comparing water pressure with spring force, and controlling the position and the angle of a control valve core (7) under the action of a special cam mechanism, consisting of an inner cylinder cam (11) and a sliding block (4), of the valve. The mechanical water-break automatic close water has the characteristics of simple structure, low cost and precise action.

Description

technical field [0001] The invention belongs to the technical field of tap water valves, and relates to a water cutoff automatic closing valve, in particular to a mechanical water cutoff automatic closing valve. Background technique [0002] The electromagnetic self-closing water valve can realize the function of self-closing when water is stopped, but it has the disadvantages of high cost and the need for power supply and sensors. [0003] At present, the tap water valves used in public places and general households are all old-fashioned structures, and they are made of valve bodies, rotary handles and spools. For the stop valve, the position is changed by rotating the spool, so that the rubber gasket under the spool is pressed to death at the water outlet on the valve body to shut off the waterway; for the ball valve, the valve port of the ball valve is changed by rotating the spool position to shut off the waterway. The disadvantage of these valves is that there is no s...
