Abstract

Provided is a gas pressure detector. The gas pressure detector comprises a water-gas separation tank, a gas pipe and a gas pressure meter. The water-gas separation tank is provided with a water inlet and a water drainage sluice valve. The gas pressure detector further comprises a four-way distribution valve, a high-pressure pipe and a connecting rod. The first end of the four-way distribution valve is communicated with the gas pipe, the second end of the four-way distribution valve is communicated with the gas pressure meter, and the third end of the four-way distribution valve is communicated with the water inlet in the water-gas separation tank through the high-pressure pipe. The gas pressure detector mainly solves the problem that in the prior art, gas pressure measurement is inaccurate, enables gas to be completely separated from confined water in a coal seam in the coal seam pressure detecting process, and eliminates the water pressure factor affecting coal seam gas pressure.

Description

technical field [0001] The invention belongs to the technical field of gas drainage and relates to a gas pressure detector. Background technique [0002] Coal mine gas is one of the main factors threatening the safe production of coal mines. In order to ensure safe production, the coal seam to be mined must be tested for gas pressure in advance in accordance with the safety production norms. Coal seam gas pressure refers to the pressure of free gas contained in coal seam pores, that is, the pressure of gas acting on the pore wall, which is the driving force for gas to emerge from the coal seam and is also a sign of the gas content in the coal seam. The gas pressure detection needs to drill a detection hole in the coal seam to be mined, and directly read the gas pressure value with the gas pressure detector through the piezometric tube drawn from the detection hole. Accurate determination of gas pressure is effective and reasonable for the prevention and control of gas disas...
