Abstract
The invention relates to a gas extraction teaching aid which comprises a grid-connecting pipe fixed horizontally on a teaching platform. One end of the grid-connecting pipe is connected with a hole opening bending head through a right angle bending head. The hole opening bending head is of a T-shaped structure and comprises a horizontal pipe and a vertical pipe. A sealing cover is arranged at one end opening of the horizontal pipe which is provided with a sampling opening. The other end of the grid-connecting pipe is connected with a hole plate flow meter. The gas extraction teaching aid further comprises a negative pressure sampler, an optics gas meter and a valve air bag. The gas extraction teaching aid is simple in structure and solves the problem that currently, teaching of gas extraction skills to new workers is only in a written mode and an oral mode, and teaching effect is bad.
Description
Technical field
The invention belongs to colliery engineering teaching aid field, relate in particular to a kind of gas pumping teaching aid.
Background technology
Fast development along with national economy, needs to the energy constantly increase, coal mining work is constantly accelerated, thereby the post of coal mining industry needs also to increase gradually, it is the important step of coal mining that fire damp is administered, how to make the new worker grasp as early as possible the coal mine gas drainage basic skills and become coal mine gas drainage department problem demanding prompt solution, now mainly by the explanation of written and oral aspect, carry out the training of extraction basic skills, but due to can not with the effective combination of down-hole site environment, cause result of training undesirable, new worker's gas pumping level is very different, in the course of time there will be the skimble-scamble phenomenon of extraction standard, production has brought potential safety hazard to downhole safety.
Summary of the invention
The purpose of this invention is to provide a kind of gas pumping teaching aid, solution is carried out the gas pumping skill teaching to the new worker now and is existed only in written and oral aspect, the problem that teaching efficiency is poor.
For achieving the above object, technical scheme of the present invention is, a kind of gas pumping teaching aid, comprise,
A teaching platform, for fixing and webmaster;
One and webmaster are pipelines be horizontally fixed on teaching platform, for gas drainage pipeline under simulation well;
An aperture elbow, be used to simulating the extraction borehole opening arrangement, described aperture elbow is T-shaped structure, is comprised of horizontal tube and VERTICAL TUBE, horizontal tube one port is equipped with capping, and thief hatch is installed on horizontal tube;
A square elbow, be used to connect the aperture elbow and and webmaster, the first end of quarter bend is connected with the VERTICAL TUBE end opening of aperture elbow, the other end is connected with webmaster front end also;
An orifice flowmeter, be used to measuring extraction negative pressure, gas differential pressure data, orifice metre with and the webmaster rear end be connected;
A negative pressure sampler, be used for taking a sample for the gas in the extraction pipeline;
An optics gas instrument, for detection of the gas density of institute's gas production body;
A valve air bag, be used to collecting the gas of negative pressure sampler extraction.
The present invention is simple in structure, by level on teaching platform, one and webmaster are installed, gas drainage pipeline under simulation well, and the webmaster front end by square elbow, an aperture elbow is installed, for simulating the extraction borehole opening arrangement, and the webmaster rear end orifice flowmeter is installed, and be equipped with the negative pressure sampling thief that gas pumping is used, optics gas instrument, thereby the valve air bag forms the down-hole extraction environment of a simulation, the new worker can use the negative pressure sampling thief, optics gas instrument, the instruments such as valve air bag are practised gas pumping on teaching platform, this teaching aid combines books with actual, improved greatly the effect of gas pumping teaching.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the schematic diagram of aperture of the present invention elbow.
Embodiment
As shown in Figure 1, a kind of gas pumping teaching aid, comprise an also webmaster 2 be horizontally fixed on teaching platform 1, and webmaster 2 one ends are connected with aperture elbow 4 by square elbow 3, the aperture elbow is T-shaped structure, horizontal tube and VERTICAL TUBE, consist of, horizontal tube one port is equipped with capping 41, and thief hatch 42 is installed on horizontal tube; And webmaster 2 other ends are connected with orifice flowmeter 5; Also comprise 7, one valve air bags of 6, one optics gas instrument of a negative pressure sampler.
During use, the new worker wears negative pressure sampler, optics gas instrument, valve air bag on request, then by the gas pumping rule, carries out analog sampling at the thief hatch of aperture elbow, the thief hatch of orifice flowmeter, and optics gas instrument is used in exercise.
