Description

Technical Field

[0002] Air pulse solenoid valves are often used in certain types of air compression equipment or control systems. It is designed to control the flow of air or gas, usually controlled by an electrical signal. This solenoid valve usually opens or closes by receiving an electrical signal to control the flow of air or gas. It can be used in compressed air systems to control the piston movement of a cylinder, or to control other pneumatic equipment that requires precise control. These solenoid valves are often widely used in industrial automation systems to control pneumatic actuators, air compression systems, pneumatic transmission systems, etc. Their working principle is to use the magnetic field generated by the electromagnet to control the position of the valve core, thereby controlling the flow of fluid. In general, air pulse solenoid valves play an important role in industrial and mechanical equipment, and realize many functions of automation and control systems by precisely controlling the flow of gas or air.

[0003] When the existing solenoid valve is used, there is no dustproof net, and the air is prone to carry a lot of dust and impurities.
