Overview of the principle and main parameters of ultra-high pressure solenoid valve

Ultra-high pressure solenoid valves are mainly used in hydraulic transmission systems, petrochemical equipment, metallurgical industry, sprayer humidification, aerospace, military, China's nuclear industry, shipbuilding machinery, electric power engineering, electric energy, large city heating, steam supply, power supply, etc. All walks of life. Completed the automation technology and remote operation of the high-voltage system software.

    Principle of ultra-high pressure solenoid valve:

    Normally closed: When the solenoid coil is plugged in, the pilot valve core is closed, the pilot hole is opened, the upper cavity of the valve is released, the piston rod is promoted by the medium pressure in the lower cavity, and the relay is opened. When the solenoid coil is turned off, the pilot valve core is reset by the spring, the pilot hole is closed, the upper cavity of the valve is increased and reset by the piston rod throttle valve hole, and the relay is turned off.

    On and off: When the solenoid coil is plugged in, the pilot valve core is reset by the spring, the pilot hole is closed, the upper cavity of the valve is increased by the piston rod throttle hole and the torque of the reset spring is increased, and the relay is turned off. When the solenoid coil is turned off, the pilot valve core is reset by spring yellow, the pilot hole is opened, the upper cavity of the valve is released, the piston rod is promoted by the medium pressure in the lower cavity, and the relay is opened.

    Note: If the pressure at the inlet and outlet exceeds the pressure at the inlet, the medium will be reversed. A check valve can be installed.
