The electric flow control valve water is a pilot solenoid valve with secondary opening. Its structure is mainly composed of a pilot valve and a main valve. The main valve adopts a rubber sealing structure. At constant position, the movable iron core closes the guide valve opening, the pressure in the valve chamber is balanced, and the main valve opening is closed. When the coil is electrified, electromagnetic force is generated to suck up the active iron core, and the medium in the main valve chamber leaks out from the guide valve mouth, resulting in pressure difference. The diaphragm or valve cup is quickly lifted, the main valve mouth opens, and the valve presents a path. When the coil is cut off, the magnetic field disappears, the movable iron core is reset, the guide valve mouth is closed, and the pressure in the guide valve and the main valve chamber is balanced, the valve is closed again.
