Problems solved by technology

[0002] Solenoid valves, as executive components for industrial process automation control systems, are widely used in all walks of life, but because the explosion-proof solenoid valves used today are not waterproof or dustproof, their working reliability is caused by most workplaces in coal mines. In addition, the electromagnetic valve and the control unit are separated from each other by different components and the explosion-proof certification also limits the use of the occasion. It can only be treated as a component and cannot be used as a device, which also limits its large-scale application, just as Patent application (patent) number: 02130310.X solenoid valve, the problem of its use in harsh environments is easy to block and easy to fail, application (patent) number: 02107696.0 The solenoid valve of the braking system can only be used in special environments, There is an urgent need for a mining explosion-proof pneumatic actuator that integrates a solenoid valve and an intelligent control unit, which has strong adaptability, low production cost, and can work stably for a long time without maintenance in the harsh environment mentioned above. Reliable control to ensure that the pneumatic equipment can meet the working needs
