Working principle and characteristics of water solenoid valve

working principle

    The water solenoid valve is a pilot-operated solenoid valve with a secondary valve opening. The structure is mainly composed of a pilot valve and a main valve, and the main valve adopts a rubber sealing structure. When the position is normal, 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, an electromagnetic force is generated to attract the movable iron core, and the medium in the main valve chamber is leaked from the pilot valve port, so that a pressure difference is generated, the diaphragm or the valve cup is quickly lifted, the main valve port is opened, and the valve is presented. The passage is gone. 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 chamber is balanced, and the valve is closed again.

Characteristics

  • The water solenoid valve adopts a direct-acting diaphragm structure without pressure to start, expanding its field of use.

  • The flat diaphragm structure is reliable in opening and closing and enhances the service life of the product.

  • The use of plastic-sealed coils enhances the safe use of this product in a wide range of environments.
