The pilot type diaphragm solenoid valve is a pilot type solenoid valve with secondary opening. Its structure is mainly composed of a pilot valve and a main valve. The main valve adopts a rubber seal structure. In normal position, the movable iron core seals the pilot valve port, the pressure in the valve chamber is balanced, and the main valve port is closed. When the coil is energized, electromagnetic force will be generated to suck up the movable iron core, and the medium in the main valve cavity will leak out from the pilot valve port, resulting in a pressure difference. The diaphragm or valve cup will be quickly lifted, and the main valve port will be opened, and the valve will be in a path. When the coil is powered off, the magnetic field disappears, the movable iron core resets, the pilot valve port is closed, and the pressure in the pilot valve and the main valve chamber is balanced, the valve is closed again.
