The structure of the opening and closing parts of the valve core extending out of the valve will be applied to the dynamic seal. After the valve is used for a long time , there is usually leakage. In order to solve the problem of external leakage caused by the long-term operation of the opening and closing parts of the valve core, the electromagnetic valve is used more at present, which is completed by using electromagnetic force to act on the iron core sealed in the magnetic isolation sleeve of the electric control valve. Due to the dynamic sealing structure, the external leakage is easy to be blocked. However, the solenoid valve has a complex structural design and is easily limited in use.
