Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valves, in particular to an electromagnetic valve with ultra-high wear resistance. Background Art

[0002] Solenoid valves are basic components for adjusting the direction, flow, speed and other parameters of media in industrial control systems. They are actuators and are not limited to hydraulic or pneumatic. They can be used with different circuits to achieve the desired control and ensure the accuracy and flexibility of control. The appearance of the solenoid valve is generally printed with a product gas circuit diagram. By understanding this gas circuit diagram, you can understand the positions that the valve core can change. The most common ones are two frames and three frames, which means that the valve core can switch between two or three positions, also known as two-position and three-position.

[0003] However, the service life of the conventional solenoid valve for starting and stopping the liquid flow tube is far shorter than that of the air flow tube. The main reason is that the movable ball and valve plate used for closing are mainly made of metal materials. Long-term liquid erosion will cause the movable ball and the valve plate themselves to rust. The use of alloy steel can avoid rust, but alloy steel is not pressure-resistant. Long-term impact of the movable ball caused by the spring will cause the valve plate to avoid marks or gaps. In order to solve this technical problem, the utility model proposes a solenoid valve with ultra-high wear resistance. Utility Model Content
