Solenoid valve for water

There is a closed cavity in the water solenoid valve, with through holes at different positions. Each hole leads to a different oil pipe. There is a valve in the middle of the cavity and two electromagnets on both sides. Which side of the magnet coil is energized and the valve body will Wherever it is attracted, different oil drain holes are blocked or leaked by controlling the movement of the valve body. While the oil inlet hole is normally open, the hydraulic oil will enter the different oil drain pipes, and then be pushed by the pressure of the oil. The piston of the oil cylinder drives the piston rod, and the piston rod drives the mechanical device. In this way, the mechanical movement is controlled by controlling the current of the electromagnet. This valve is a pilot-operated solenoid valve that opens twice. Its structure mainly consists of a pilot valve and a main valve. The main valve adopts a rubber sealing structure. In the normal position, the movable iron core seals the pilot valve port, the pressure in the valve cavity is balanced, and the main valve port is closed. When the coil is energized, electromagnetic force is generated to suck up the movable iron core, and the medium in the main valve cavity leaks out of the pilot valve port, resulting in a pressure difference. The diaphragm or valve cup is quickly lifted up, the main valve port opens, and the valve becomes Passage. When the coil is powered off, the magnetic field disappears, the movable iron core resets, and the pilot valve port is closed. After the pressure in the pilot valve and main valve cavity is balanced, the valve is closed again.
