The solenoid valve can cooperate with different circuits to achieve the expected control, and both the control accuracy and flexibility can be guaranteed. The valve stem is an important component in the solenoid valve. For example, a solenoid valve stem in the technical field of solenoid valves disclosed in the patent number CN220204855U. Through the provided valve stem body, fixing block, and sealing ring, it can effectively prevent impurities in the liquid from entering the interior of the valve body and avoid the situation of blockage inside the valve body. Through the provided dust-proof ring, the dust-proof ring improves the sealing performance inside the valve body, increases the reliability of the seal, and further prevents impurities in the fluid from entering the seal in the sliding hole, reducing the service life of the solenoid valve and also reducing the usage effect.
