Abstract
The present invention relates to a kind of gas pumping teaching aid, including an also webmaster being horizontally fixed on teaching platform, and webmaster one end is connected with aperture elbow by elbow bend, aperture elbow is T-type structure, it is made up of horizontal tube and VERTICAL TUBE, horizontal tube Single port is provided with capping, and horizontal tube is provided with thief hatch；And the webmaster other end is connected with orifice flowmeter；Also include a negative pressure sampler, an optics gas instrument, a valve air bag.Present configuration is simple, solves that new worker carries out gas pumping skill teaching now and exists only in written and oral aspect, the problem of teaching efficiency difference.
Description
Technical field
The invention belongs to colliery engineering teaching aid field, particularly relate to a kind of gas pumping teaching aid.
Background technology
Fast development along with national economy, the needs of the energy are continuously increased, coal mining work is constantly accelerated, thus the post of coal mining industry needs also to be gradually increased, fire damp improvement is the important step of coal mining, how to make new worker grasp coal mine gas drainage basic skill as early as possible and become coal mine gas drainage department problem demanding prompt solution, explanation today mainly by written and oral aspect carries out the training of extraction basic skill, but owing to effectively can not be combined with underground site environment, cause result of training undesirable, the gas pumping level of new worker is very different, in the course of time there will be the skimble-scamble phenomenon of extraction standard, produce to downhole safety and bring potential safety hazard.
Summary of the invention
It is an object of the invention to provide a kind of gas pumping teaching aid, solve that now new worker is carried out gas pumping skill teaching and exist only in written and oral aspect, the problem of teaching efficiency difference.
For achieving the above object, the technical scheme is that, a kind of gas pumping teaching aid, including,
One teaching platform, for fixing and webmaster；
One and webmaster, be a pipeline being horizontally fixed on teaching platform, be used for simulating down-hole gas sucking releasing pipeline；
One aperture elbow, is used for simulating extraction borehole opening arrangement, and described aperture elbow is T-type structure, is made up of horizontal tube and VERTICAL TUBE, and horizontal tube Single port is provided with capping, and horizontal tube is provided with thief hatch；
One elbow bend, is used for connecting aperture elbow and also webmaster, and elbow bend one end is connected with the VERTICAL TUBE end opening of aperture elbow, and the other end is connected with also webmaster front end；
One orifice flowmeter, is used for measuring extraction negative pressure, gas differential pressure data, and orifice metre is connected with also webmaster rear end；
One negative pressure sampler, the gas in extraction pipeline is used for sampling；
One optics gas instrument, for detecting the gas density of institute's gas production body；
One valve air bag, for collecting the gas of negative pressure sampler extraction.
Present configuration is simple, by being horizontally mounted one and webmaster on teaching platform, simulation down-hole gas sucking releasing pipeline, by elbow bend, one aperture elbow is installed in also webmaster front end, for simulating extraction borehole opening arrangement, at also webmaster rear end installing hole flowmeter, and it is equipped with the negative pressure sampler of gas pumping, optics gas instrument, valve air bag thus formed one simulation down-hole extraction environment, new worker can use negative pressure sampler, optics gas instrument, gas pumping practised on teaching platform by the instruments such as valve air bag, books are combined by this teaching aid with actual, greatly improve the effect of gas pumping teaching.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the schematic diagram of aperture of the present invention elbow.
Detailed description of the invention
As shown in Figure 1, a kind of gas pumping teaching aid, including an also webmaster 2 being horizontally fixed on teaching platform 1, and webmaster 2 one end is connected with aperture elbow 4 by elbow bend 3, aperture elbow is T-type structure, being made up of horizontal tube and VERTICAL TUBE, horizontal tube Single port is provided with capping 41, and horizontal tube is provided with thief hatch 42；And webmaster 2 other end is connected with orifice flowmeter 5；Also include a negative pressure sampler 6, an optics gas instrument 7, a valve air bag.
During use, new worker wears negative pressure sampler, optics gas instrument, valve air bag on request, then presses gas pumping rule and is simulated sampling at the thief hatch of aperture elbow, the thief hatch of orifice flowmeter, and practises using optics gas instrument.
