Working Principle of Solenoid Water Control Valve

Working Principle of Solenoid Water Control Valve

The pilot type solenoid valve with secondary opening valve is mainly composed of pilot valve and main valve, and the main valve adopts rubber sealing structure. At constant position, the movable iron core closes the guide valve opening, the pressure in the valve chamber is balanced, and the main valve opening is closed. When the coil is electrified, electromagnetic force is generated to suck up the active iron core, and the medium in the main valve chamber leaks out from the guide valve mouth, resulting in pressure difference. The diaphragm or valve cup is quickly lifted, the main valve mouth opens, and the valve presents a path. When the coil is cut off, the magnetic field disappears, the movable iron core is reset, the guide valve orifice is closed, and the pressure in the guide valve and the main valve chamber is balanced, the solenoid water control valve is closed again.

Solenoid water control valve: There is a closed chamber in the water solenoid valve. There are through holes in different positions, each of which leads to different tubing, with valves in the middle and two electromagnets on both sides. Where the magnet coil is electrified, the valve body will be attracted to which side, and the movement of the valve body will be controlled by electromagnetic water to stop or leak out different oil discharge holes. The intake holes are usually open, and the hydraulic oil will enter different discharge pipes. Then the piston of the cylinder will be driven by the pressure of the oil, and the piston rod will drive the piston rod, and the piston rod will drive the mechanical device. In this way, the mechanical motion is controlled by controlling the current of the electromagnet.
