| description | The utility model discloses a coal-mine gas drill hole comprehensive parameter determinator. The determinator comprises a PVC pipe for connecting a drill hole and a drainage pipe and a bypass pipe arranged on the PVC pipe. The PVC pipe is provided with an anti-seismic pressure meter for measuring the negative pressure of the drill hole. The bypass pipe is provided with an orifice plate flowmeter for measuring the flow of the drill hole. The portions, on the two sides of the orifice plate flowmeter, of the bypass pipe are provided with pipe openings connected with a U-shaped differential pressure gauge for measuring the pressure difference of an orifice plate. The middle end of the PVC pipe is provided with a ball valve for closing the drill hole. The bypass pipe is provided with a measuring hole for measuring the concentration of gas. The anti-seismic pressure meter is used for measuring the negative pressure of the drill hole, the orifice plate flowmeter is used for measuring the flow of the drill hole, and gas inspection equipment is used for measuring the concentration of the gas from the gas measuring hole. Compared with an electronic gas comprehensive parameter determinator, the coal-mine gas drill hole comprehensive parameter determinator has the advantages of being easy and convenient to operate, precise and reliable in measuring data, not prone to damage, easy to maintain and the like. |
