Abstract
The utility model relates to a gas extraction teaching aid, which comprises an incorporating pipe which is horizontally fixed on a teaching platform, wherein one end of the incorporating pipe is connected with an orifice elbow through a right-angle elbow, the orifice elbow is of a T-shaped structure and is composed of a horizontal pipe and a vertical pipe, one port of the horizontal pipe is provided with a sealing cover, and the horizontal pipe is provided with a sampling port; the other end of the incorporating pipe is connected with a orifice plate flowmeter; and the gas extraction teaching aid further comprises a negative pressure sampler, an optical gas meter and a valve air bag. The gas extraction teaching aid has simple structure, and solves the problems that the gas extraction skill teaching for new workers only exists in written and verbal level and the teaching effect is poor.
Description
Technical field
The utility model belongs to colliery engineering teaching aid field, relates 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 new worker grasp as early as possible 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, to downhole safety, produce and brought potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of gas pumping teaching aid, and solution is carried out gas pumping skill teaching to new worker now and existed only in written and oral aspect, the problem that teaching efficiency is poor.
For achieving the above object, the technical solution of the utility model is, a kind of gas pumping teaching aid, comprises,
A teaching platform, for fixing and webmaster;
One and webmaster are pipelines being horizontally fixed on teaching platform, for gas drainage pipeline under simulation well;
An aperture elbow, for simulating extraction borehole opening arrangement, described aperture elbow is T-shaped structure, horizontal tube and VERTICAL TUBE, consists of, horizontal tube one port is provided with capping, and thief hatch is installed on horizontal tube;
A square elbow, for connect aperture elbow and and webmaster, square elbow one end is connected with the VERTICAL TUBE end opening of aperture elbow, the other end is connected with webmaster front end also;
An orifice flowmeter, for measuring extraction negative pressure, gas differential pressure data, orifice flowmeter with and webmaster rear end be connected;
A negative pressure sampler, is used for sampling for the gas in extraction pipeline;
An optics gas instrument, for detection of the gas density of institute's gas production body;
A valve air bag, for collecting the gas of negative pressure sampler extraction.
The utility model is simple in structure, by level on teaching platform, one and webmaster are installed, gas drainage pipeline under simulation well, and webmaster front end by square elbow, an aperture elbow is installed, be used for simulating extraction borehole opening arrangement, and 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 valve air bag forms the down-hole extraction environment of a simulation, new worker can use 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of the utility model aperture elbow.
Embodiment
As shown in Figure 1, a kind of gas pumping teaching aid, comprise an also webmaster 2 being horizontally fixed on teaching platform 1, and webmaster 2 one end are connected with aperture elbow 4 by square elbow 3, aperture elbow is T-shaped structure, horizontal tube and VERTICAL TUBE, consist of, horizontal tube one port is provided 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, new worker wears negative pressure sampler, optics gas instrument, valve air bag on request, then by gas pumping rule at the thief hatch of aperture elbow, the thief hatch of orifice flowmeter carries out analog sampling, and optics gas instrument is used in exercise.
