The Working Principle of High Pressure Water Solenoid Valve

1. Structure composition of high pressure water solenoid valve

The high-pressure 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. 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 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 is open. 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.

2. Working principle of high pressure water solenoid valve

There is a closed cavity in the high-pressure water solenoid valve with through holes at different positions. Each hole leads to a different tubing. In the middle of the cavity is the valve and two electromagnets on both sides. Which side of the magnet coil is energized and the valve body will be attracted to which side, by controlling the movement of the valve body to block or leak different oil discharge holes, and the oil inlet hole is normally open, the hydraulic oil will enter the different oil discharge pipes, and then the piston of the oil cylinder will be pushed by the oil pressure, the piston will drive the piston rod, and the piston rod will drive the mechanical device to move. In this way, the mechanical movement is controlled by controlling the current of the electromagnet.
