Abstract

The utility model relates to a component of a device for gas drainage under coal mines, in particular to a telescopic PE pipe connecting device for gas drainage under coal mines, with the view of solving the gas leakage problem arising from the use of devices based on hole connection technology in gas drainage and the problem in adjusting the length of a connecting pipe. The device comprises a reducing through pipe, wherein, locking nuts provided with internal threads are arranged at the two ends of the reducing through pipe respectively, clamping sleeves are arranged in the non-thread sections of the locking nuts, and seal rings and clamp rings are arranged between the clamping sleeves and the ports. The utility model, because of scalability, can be used in adjusting the heights of and the spaces among different boreholes, thereby realizing orderly pipeline arrangement, solving the problem of water logging caused by unevenness in pipeline arrangement, and achieving standardized operation.

Description

The scalable PE pipe connection of underground mine use gas extraction
Technical field
The utility model relates to the component that carry out the gas pumping device under a kind of coal mine, is specially the scalable PE pipe connection of a kind of underground mine use gas extraction.
Background technique
At present, coal mine gas extraction work has become the important process that high gassy mine and coal and gas outburst mine must carry out.In gas pumping work, boring connection hole technology is a kind of technical measures of using always, by hole and extraction pipeline couples together, make gas in the coal body by extraction boring by joining bore portion, enter extraction pipeline.At present, the material of domestic each colliery connection hole employing mainly is coiler, iron pipe elbow, threeway, stop valve, iron wire etc.The connection hole has general employing single hole to connect.Main technique is: adopt equipment such as coiler, iron pipe elbow, iron pipe threeway, iron wire, tailrace, will couple together between drilling and sealing pipe and the extraction pipeline threeway.This hole technology can be passed through the extraction of pipeline negative pressure in extraction pipeline with the gas in the boring, and extraction by the road is in main system, it is numerous and diverse that but single hole connects operation, adjust pipeline length and cut the coiler realization by sanction, field operation is lack of standardization, air leakage is big, and the material reusability is low, can not satisfy two anti-requirements.
Summary of the invention:
The utility model provides a kind of underground mine use gas extraction scalable PE pipe connection for the gas leakage problem that solves the device existence of using connection hole technology in the gas extraction process with adjusting the connecting tube length issue.
The utility model is realized by following technological scheme, the scalable PE pipe connection of a kind of underground mine use gas extraction, comprise the reducing coupling pipe, reducing coupling pipe two ends are respectively equipped with the lock nut that has internal thread, be provided with the chucking cover in non-threaded section of lock nut, be provided with seal ring, snap ring between chucking cover and the port.
Compared with prior art, 1, the utility model adopts the PE material, this material has been realized antistatic, fire-retardant requirement.2, the diameter difference of reducing coupling pipe both sides, thus realize the different tube diameters PE pipe that both sides connect, and can stretch by two logical inside.3, two logical both sides are advanced nut etc. by chucking cover, seal ring, snap ring, lock the releasing pipe of both sides are fixed, and satisfy the technical requirements of the normal operation of extraction system under malleation, the negative pressure condition.It is fastening only need to utilize special tool to carry out during use, can solve envelope and connect hole gas leakage problem, can thoroughly solve the connection gas leakage problem that manual operation (iron wire is twisted not tight) causes.4, by using the utility model, because it has scalability,, can realize that extraction pipeline is horizontal vertically flat so can adjust to different drillhole heights, spacing, solved the ponding problem that the pipeline injustice causes, realized standardized work simultaneously.Regulate horizontal length and vertical height by pipeline is flexible, no longer need to carry out the extraction pipeline sanction and cut, make the store keeping standardization, improved the reusability of connection hole material greatly, significantly reduce connection hole cost.5, this device can satisfy the requirement of fire damp extraction boring negative pressure and malleation.

Embodiment
As schematically shown in Figure 3, the scalable PE pipe connection of a kind of underground mine use gas extraction, comprise reducing coupling pipe 2, reducing coupling pipe 2 two ends are respectively equipped with the lock nut 1,3 that has internal thread, be respectively equipped with chucking cover 4,9 in non-threaded section of lock nut 1,3, be respectively equipped with seal ring 6,7, snap ring 5,8 between chucking cover 4,9 and the port.
Described lock nut 1,3 inboards comprise thread section and conical surface section, and chucking cover 4,9 appearances are the stage body shape, and lock nut 1,3 and reducing coupling pipe 2 are threaded, the conical surface section of lock nut 1,3 and chucking cover 4,9 adjacency.So, chucking cover connects the pipeline of carrying gas, then by the rotational lock nut will tighten cover, the reducing coupling pipe closely links together, and plays good sealing effect.
Scalable PE pipe connection is when carrying out gas pumping under the coal mine, for the boring that reaches different heights, different spacing is coupled to the new device that standardized extraction management mode is used.
