Working Principle of Solenoid Valve

   After looking at the dynamic diagram, is it found that the working principle of solenoid valve is very simple? When the solenoid valve is not electrified, the needle under the action of the spring will gamble the passage of the valve body, and the solenoid valve is in the cut-off state. When the coil is connected to the power supply, the coil produces magnetic force, the valve core is lifted upward to overcome the spring force, the inner passage of the valve is opened, and the solenoid valve is in the state of conduction.
