Description

Novel mining gas drainage blowout prevention device Technical Field The utility model belongs to the technical field of gas extraction, and particularly relates to a novel mining gas extraction blowout preventer. Background The gas extraction is to extract the gas in the coal seam and the goaf to the ground through the drill holes, so that the underground gas concentration is reduced, the gas can be further utilized, the gas in the coal seam and the goaf is extracted, the emission of the gas can be reduced, explosion and outburst accidents are prevented, mine safety is ensured, and the gas can be utilized as clean energy. In the process of extracting gas, because the content of the gas in the underground is large, sometimes the amount of the gas sprayed is too large, so that the pressure in the pipeline is increased and a series of adverse reactions can be generated, and a certain influence can be generated on the extraction. Disclosure of utility model The utility model aims to solve the problems that in the process of extracting gas, the content of the gas in the underground is large, sometimes the ejection amount of the gas is easily caused to be too large, the pressure in a pipeline is increased, a series of adverse reactions can be generated, and the extraction can be influenced to a certain extent. The novel mining gas extraction blowout preventer comprises a shell, wherein an air outlet pipe is arranged on one side of the shell, a buffer component is arranged in the shell, a filter component is arranged on the other side of the shell, the buffer component comprises an air bag, a fixing plate is fixedly arranged on the top surface of the air bag, an exhaust pipe is fixedly arranged on the top surface of the fixing plate, a connecting rod is slidably arranged on the fixing plate through a through hole formed in the fixing plate, a connecting ring is fixedly arranged at the top end of the connecting rod, a mounting plate is fixedly arranged at the bottom end of the connecting rod, a spring is arranged on the outer wall of the connecting rod, and a plug block is fixedly arranged on the top surface of the mounting plate.
