Abstract

The invention discloses a gas extraction drilling coupling device and an installation and use method thereof, wherein the coupling device is composed of a seal connection pipe fitting, a vertical connection pipe fitting, a five-way valve, a transverse connection pipe fitting and a gas extraction header connection pipe fitting; the gas outlet of the seal connection pipe fitting is in tight coupling with the gas inlet of the five-way valve via the vertical connection pipe fitting; and the gas outlet of the five-way valve is in tight coupling with the gas inlet of the gas extraction header connection pipe fitting via the transverse connection pipe fitting. The installation and use method of the invention is simple and feasible, has the advantages of easy operation, various adjustment, rapid coupling speed, strong practicability and easy promotion and application, and improves the safety performance of the coal mine gas extraction operation to the full.

Description

technical field [0001] The invention belongs to the technical field of gas drainage in coal mines, and in particular relates to a gas drainage drilling coupling device formed in the coal seam of the coal mine along the bed and after the holes are sealed, and an installation and use method thereof. Background technique [0002] Coal seam gas drainage is one of the most effective methods to control mine gas and prevent coal and gas outburst. It is not only the need of safe production, but also the urgent need of saving energy and protecting the environment. The pipe union is the key equipment to ensure the smooth progress of gas drainage, and the gas concentration is the prerequisite for determining whether the extracted gas can be used. For a long time, my country's gas drainage drilling unions have mainly used iron valve bodies and double-resistant suction and discharge pipes, which are bound with iron wires. There are many problems in this kind of pipe connection, mainly in...
