A mine explosion-proof pneumatic actuator integrating solenoid valve and control unit

Abstract

The invention discloses a mining explosive-proof pneumatic executive device integrating a solenoid valve and a control unit, and belongs to the technical field of mine production process automation. The mining explosive-proof pneumatic executive device integrating the solenoid valve and the control unit is characterized in that work equipment with pressure fluid as a power source achieves various motions or rhythms under the control of the control unit, the mining explosive-proof pneumatic executive device integrates the solenoid valve and the intelligent control unit, according to the device, the body portion, the motion portion and the control portion of the solenoid valve are arranged in an explosive-proof box for coal mine explosion-proof certification, the integration of the motions and control is achieved, the control can be executed conveniently, and dust prevention and water prevention are achieved. The mining explosive-proof pneumatic executive device can be applied to any occasion of a pneumatic system, the intellectualization, modularization, serialization and set completion of the solenoid valve and the control unit are achieved under the specific environment of a coal mine, and the device is widely suitable for various control execution devices with the pressure fluid as work media in the coal mine, petrochemical engineering, metallurgy, electric power, environment protection and other systems and industries.

AI Technical Summary

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) No.: 02130310.X solenoid valve, the problem of its use in harsh environments is that it is easy to block and fail. Application (patent) No.: 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
