At present, a water control valve on the market mainly comprises a valve body, a floater, a lever, a sealing plug and a diaphragm type valve core assembly, wherein the diaphragm type valve core assembly comprises a rubber diaphragm, a valve seat and a diaphragm seat, the rubber diaphragm corresponds to the valve seat, the rubber diaphragm is fixed on the diaphragm seat, a pilot cavity is arranged between the rubber diaphragm and the diaphragm seat, a through hole corresponding to a water inlet is formed in the rubber diaphragm, a pressure relief hole is formed in the lower portion of the diaphragm seat, and when the floater moves up and down, the sealing plug is driven to move through a transmission piece, and the pressure relief hole is blocked or opened. The working principle of the automatic water control valve is as follows: when the water level in the container is lower than the set water level, the floater sinks, the pressure relief hole is opened, the pilot cavity is in an open state, the rubber diaphragm is recessed into the pilot cavity under the action of water pressure, the rubber diaphragm is separated from the valve seat, the water inlet and the water outlet are communicated, and the valve is opened; when the water level in the container reaches a set water level, the floater rises, the pressure relief hole is blocked through the sealing plug, the pilot cavity is in a closed state, at the moment, pressure water enters the pilot cavity through the through hole in the rubber diaphragm, the pressure in the pilot cavity rises, the rubber diaphragm is pushed to move upwards until the rubber diaphragm completely blocks the valve seat, the channel between the water inlet and the water outlet is blocked, and the valve is closed. The following technical defects exist when in use: 1. when the valve is opened, the elastic tension of the rubber diaphragm can be overcome until the water inlet of the water inlet reaches a certain pressure, and certain conditions are limited for use places. 2. When the valve is closed, the time for the rubber diaphragm to block the valve seat is too long, the response is slow, and the sensitivity is low. SUMMERY OF THE UTILITY MODEL
