Description
Technical field
The utility model relates to a kind of gas discharge drilling sealing material, specifically a kind of experimental provision detecting gas discharge drilling sealing material sealing property.
Background technology
The main method of China's coal-mine gas pumping is hole pumping and mining; The encapsulant of current hole pumping and mining is mainly polyurethanes expanded material, cement etc., but these materials generally have shrinkability, and the boring determining China's current down-hole extraction is generally leaked gas seriously, produces harmful effect to the extraction of gas and the safety in mine.
Generally lack now a kind of effective detection means and become the situation of leaking gas in boring to the shrinkability in the boring verifying these materials and along with the stream of time.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of experimental provision detecting gas discharge drilling sealing material sealing property, is carried out the shrinkage of test material by the permeance property of gases at high pressure, and thinking is simple, effect is directly perceived.
To achieve these goals, the technical solution adopted in the utility model is: a kind of experimental provision detecting gas discharge drilling sealing material sealing property,
It comprises the material tests pipe for holding encapsulant;
The described left and right two ends of material tests pipe are respectively by left flange plate, right flangeseal;
Described material tests pipe left end is communicated with tensimeter, left valve and air compressor successively by left pipeline;
Described material tests pipe right-hand member is communicated with right valve, flowmeter and water tank successively by right pipeline.
Described left flange plate is by screw and rubber cushion sealing.
Described right ring flange is by screw and rubber cushion sealing.
Described material tests pipe two ends adopt cotton yarn to carry out shutoff simultaneously.
The end of described right pipeline stretches into below the liquid level of water tank.
Described material tests tube shape material tests tubing matter is PE material, and diameter gets the straight tube of 80-115mm.
Compared with existing device, this experimental provision carrys out the shrinkage of test material by the permeance property of gases at high pressure, its thinking is simple, effect directly perceived, has good Detection results; More high-quality encapsulant can be selected by this device and method, eliminate encapsulant inferior.

In figure: 1, material tests pipe, 2, left flange plate, 3, tensimeter, 4, left valve, 5, left pipeline, 6, air compressor, 7, screw, 8, right valve, 9, right rain glass, 10, right pipeline, 11, water tank, 12, rubber cushion, 13, cotton yarn, 14, encapsulant.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of experimental provision detecting gas discharge drilling sealing material sealing property,
It comprises the material tests pipe 1 for holding encapsulant 14, and wherein encapsulant 14 is full of material tests pipe 1;
The described left and right two ends of material tests pipe 1 seal respectively by left flange plate 2, right ring flange 15;
Described material tests pipe 1 left end is communicated with tensimeter 3, left valve 4 and air compressor 6 successively by left pipeline 5;
Described material tests pipe 1 right-hand member is communicated with right valve 8, flowmeter 9 and water tank 11 successively by right pipeline 10.
Further, described left flange plate 2 and right ring flange 15 are all sealed by screw 7 and rubber cushion 12, and sealing effect is simply effective.
Described material tests pipe 1 two ends adopt cotton yarn 13 to carry out shutoff simultaneously, keep sealing property further.
The end of described right pipeline 10 stretches into bottom the liquid level of water tank 11, and the pressure-air visual effect carried from air compressor 6 is better.
Described material tests pipe 1 material is PE material, and diameter gets the straight tube of 80-115mm, analogue simulation down-hole boring, and this pipe manufacturer is simple, and sealing is good.
Its course of work is as follows: open air compressor 6, be filled with pressure-air, regulates the power of air compressor simultaneously, and pressure-air to be entered in material tests pipe 1 by pipeline 5 and infiltrates encapsulant 14; Pressure-air oozes out from material tests pipe 1 right-hand member opens right valve 8 simultaneously, observes the bubbles volume of right pipeline 10 in water tank 11, and then detects the performance of encapsulant 14.
In sum, this device carrys out the shrinkage of test material by the permeance property of gases at high pressure, its thinking is simple, effect directly perceived, has good Detection results; More high-quality encapsulant can be selected by this device and method, eliminate encapsulant inferior.
