Abstract
The utility model relates to a guiding pipe for pumping and discharging gas in drilling hole, which comprises a pipe body of the pipe-shaped body. A gas metering hole is opened on the pipe wall of the pipe-shaped body. The utility model is connected on the pumping and discharging pipeline of the gas in drilling hole in series when in use; with the metering hole comprising a gas collecting hole and a flux probe inserting hole positioned on the pipe wall of the guiding pipe, the utility model directly connects a detector of a portable gas pumping and discharging comprehensive parameter determinator with the metering hole on the guiding pipe when in use, thus can measure at any time and observe the pumping and discharging situation of the gas; besides, a dust insulating screen is arranged in side the pipe body in radial, thus the utility model can prevent the big granularity dust from impacting the flux probe inside the flux probe inserting hole. The utility model has the advantages of simple structure and safety and can fulfill the functions as collecting and measuring of flux, temperature and pressure of the gas, which is convenient for utilization and has good social and economic benefits, therefore, is easy for promotion and application.
Description
Technical field
The utility model relates to the matching used gas drainage under suction mozzle that is used to hole of a kind of and mining portable gas explosion extraction comprehensive parameters analyzer.
Background technology
When coal, metal or other mineral products have the part methane gas in exploitation in recovery process, overflow, brought serious threat for the safety in production of exploitation of mineral resources.At present, the mine of this type of situation of great majority existence all adopts in production face stamps many borings, and in these borings, insert elongated gas drainage under suction pipe, the other end of these boring gas drainage under suction pipes is summarised on the gas drainage under suction branch pipe(tube), extract the gas of production face inside with the large-scale gas suction pump of high negative pressure, after treating that gas drainage under suction is clean, implement again and produce exploitation.This kind mode when needs are measured gas flow, need manually be taken off the intubate on the gas drainage under suction pipe, and will be used for measuring on the detection device insertion gas drainage under suction pipe, like this, during measurement, temporary worker paid from operation costs when being expense also exists serious potential safety hazard simultaneously, uses also very complicated.
The utility model content
The purpose of this utility model is to provide a kind of gas drainage under suction mozzle that is used to hole, and is to realize security measurement, easy to use.
To achieve these goals, the technical solution of the utility model is to have adopted a kind of gas drainage under suction mozzle that is used to hole, and comprises main body, and described main body is a tubular body, and the tube wall of tubular body is provided with the gas surveying hole.
Described measured hole comprises a gas collection hole and at least one flow probe patchhole.
Described measured hole is arranged on the tube wall of tubular body vertically.
Radially be provided with the dust-separation filter screen in the described tubular body.
Described measured hole is horizontally installed on the tube wall of tubular body.
Radially be provided with the dust-separation filter screen in the described tubular body.
The outer extension of described measured hole is provided with the guiding pillar.
Mozzle of the present utility model is connected on the boring gas drainage under suction pipeline in use, because the tube wall of mozzle is provided with measured hole, measured hole comprises gas collection hole and flow probe patchhole, like this, during use, directly the probe of portable gas explosion extraction comprehensive parameters analyzer is connected with measured hole on the mozzle, just can measures at any time, observe the extraction situation of gas; In addition, radially be provided with the dust-separation filter screen in the tubular body and can stop that big dust particle impacts the flow probe in the flow probe patchhole.The utility model is simple in structure, and is safe in utilization, can realize the functions such as measurement of collection, flow, temperature and the pressure of gas sample gas, very convenient to use, has good social benefit and economic benefit, is easy to apply.
