Description

Technical Field

[0002] The solenoid valve is an industrial equipment controlled by electromagnetics. It is an automated basic component used to control fluids. It is an actuator and is not limited to hydraulics and pneumatics. It is used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. The solenoid valve includes a valve body and a valve stem. The valve body is provided with a number of working air holes, the valve body is provided with a valve cavity, and the valve stem is provided with a number of sealing rings. When the valve stem moves in the valve cavity, these sealing rings cooperate with the valve cavity to open or close the valve port in the valve cavity, thereby switching the working air holes for air outlet and exhaust. The sealing ring is prone to damage during long-term use due to the need to withstand erosion from the external environment. The existing sealing ring cannot adapt to different environments during use. For example, when used in high temperature, high pressure or corrosive environments, it will be corroded and damaged, thereby reducing its service life. Therefore, a multifunctional solenoid valve sealing ring is proposed to solve the above problem. Utility Model Content
