The concept and principle of water solenoid valve

There is a closed cavity in the water solenoid valve with through holes at different positions, and each hole leads to a different oil pipe. The valve actuator cavity is in the middle of the valve, and there are two electromagnets on both sides. Which side of the magnet coil is energized The body will be attracted to which side, by controlling the movement of the valve body to block or leak out the different drain holes, and the oil inlet hole is normally open, the hydraulic oil will enter the different drain pipes, and then through the oil The pressure pushes the piston of the oil cylinder, the piston drives the piston rod, and the piston rod drives the mechanical device to move. In this way, the mechanical movement is controlled by controlling the current of the electromagnet. The ZCS water solenoid valve of Yongjia Rilong Pump Valve Co., Ltd. is suitable for water or liquid as the working medium, and can be automatically controlled or protozoa to control the on and off of the working medium pipelines such as water, oil and liquid. Because the valve adopts rubber seal, the cleaning of working medium is greatly reduced, and it has the characteristics of rapid opening and closing and reliability.

　　The working principle of the water solenoid valve is as follows: the water solenoid valve is a pilot solenoid valve with a secondary opening. Its structure is mainly composed of a pilot valve and a main valve, and the main valve adopts a rubber seal 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 of the liquid level gauge 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 from the pilot valve port, resulting in a pressure difference. The diaphragm or valve cup is quickly lifted, the main valve port opens, and the valve becomes Access. When the coil is de-energized, the magnetic field disappears, the movable iron core is reset, the pilot valve port is closed, and the pressure in the pilot valve and the main valve cavity is balanced, the valve is closed again.
