Extraction device for gas control

Abstract

The application discloses a gas extraction device for gas control, which comprises an extraction pump, the input end of the extraction pump is fixedly connected with an extraction pipe network assembly, a buffer protection module is fixedly arranged at the outer surface of the extraction pipe network assembly, and an overpressure alarm module is arranged. In order to solve the problem that ordinary gas extraction pipe networks are prone to deformation and cracking in some positions due to extrusion or collision when used in underground coal mines, the buffer protection module is designed. Through the arrangement of the buffer protection module, the extrusion and collision positions can be supported and protected, the buffer effect is achieved, and the deformation is reduced. Meanwhile, gas leakage can be avoided when the pipeline cracks. The overpressure alarm module is further arranged, and automatic alarm is realized when excessive extrusion occurs, so that the staff can handle the problem in time, and the gas extraction device is especially suitable for use in underground coal mines.
