Structure and working principle:

1、 Structural composition

Solenoid valve is an industrial equipment controlled by electromagnetic force, which is an automation basic component used to control fluids. It belongs to actuators and is not limited to hydraulic and pneumatic systems. It is used in industrial control system to adjust the direction, flow, speed and other parameters of medium. Electromagnetic valves can be used in conjunction with different circuits to achieve the desired control, while ensuring the accuracy and flexibility of the control. There are many types of solenoid valves, and different solenoid valves play a role in different positions of the control system. Commonly used ones are one-way valves, safety valves, directional control valves, speed regulating valves, etc.

2、 Working principle

It is a principle that combines direct action and pilot type. When there is no pressure difference between the inlet and outlet, after being energized, the electromagnetic force directly lifts the pilot small valve and the main valve closing member upward in sequence, and the valve opens. When the inlet and outlet reach the starting pressure difference, after being energized, the electromagnetic force pilot small valve, the lower chamber pressure of the main valve rises, and the upper chamber pressure drops, thereby using the pressure difference to push the main valve upwards; When the power is cut off, the pilot valve uses spring force or medium pressure to push the closing member downwards, causing the valve to close.
