Description

High-performance automatic water control valve

Technical Field

The utility model relates to an automatic valve of control water level, concretely relates to automatic water control valve of high performance.

Background

The automatic water control valve is used for automatically controlling the water level, is usually used for automatically controlling the water level of water inlet in a water storage container, is internally provided with a float chamber, and is internally provided with a float which is communicated with the water storage container. 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 only when the water inlet of the water inlet reaches a certain pressure, and when the water inlet pressure is small, the situation that the valve cannot be opened often occurs, so that the water cannot be automatically fed, and the water inlet pressure of a use place has a certain requirement. 2. In general, the lower the stiffness of the rubber diaphragm (softer rubber) the faster the response speed of the valve when closed or opened, i.e. the higher the sensitivity of the valve, and vice versa the lower the sensitivity of the valve. The structure of the existing diaphragm type valve core assembly is as follows: the diaphragm seat is provided with a central shaft with an annular groove, the rubber diaphragm is provided with a central hole, the central hole of the rubber diaphragm is sleeved in the annular groove of the central shaft on the diaphragm seat, if the hardness of the selected rubber diaphragm is low, the rubber diaphragm breaks away from the diaphragm seat or turns over the back and twists when the water inlet pressure of a use place is slightly higher, and the valve is caused to lose efficacy. In order to avoid the separation, back turning or distortion of the rubber diaphragm from the diaphragm seat, the rubber diaphragm with higher hardness is generally selected, so that the sensitivity of the valve is difficult to improve, and a technical bottleneck is generated.
