Abstract
The utility model relates to a gas drainage connecting device of a coal mine, particularly to a gas drainage adjustable elbow capable of adjusting the bending direction and connecting a gas drainage pipe in a coal wall with a gas drainage main pipeline in a gate road, The utility model solves the problems that the joint part of the current gas drainage pipe in the coal wall and the gas drainage main pipeline in the gate road is deformed, blocked or leaked easily. The gas drainage adjustable elbow comprises an elbow sleeve seat and a bulb pipe, wherein the spherical end of the bulb pipe is sleeved in the sleeve seat of the elbow sleeve seat, the spherical end is sealed with the sleeve seat, and a sleeve piece is arranged in the spherical end of the bulb pipe, so that the gas drainage adjustable elbow can be adapted to the differences of the different angles of the boreholes and the different distances between boreholes in the gate road.
Description
Technical field
The utility model relates to a kind of gas extraction connection set of colliery, is specially to connect the gas extraction can regulate elbow that the interior gas of coal body is taken out the can regulate bending direction of gas extraction main pipe in real estate management and the crossheading.
Background technique
Pre-extraction before will existing the gas of coal body the inside to adopt to tax in China's highly gassy mine mining face under mine coal mining process at present.At present be laid on coal body the inside take out a lot of collieries of part that the real estate management is connected with the gas extraction main pipe all at employing common plastics tube, common PE pipe, high-pressure rubber pipe etc., bundle with iron wire and to realize connecting, this Placement does not possess fire-retardant, antistatic condition on performance.A little less than the anti-negative pressure ability of hoseline, easy tortuous deformation, stopped up by coal dust and muddy water, do not reach good extraction effect, the pipeline junction sealing effect is poor, very easily leak out toxic and harmfuls such as gas, carbon monoxide, gas leakage place and Metal Contact local even can produce spark buried very big hidden danger to the colliery safety in production.
Summary of the invention
The utility model is taken out the problems such as connection part easy deformation, obstruction or leakage of gas extraction main pipe in real estate management and the crossheading in order to solve in the existing rib gas, and a kind of gas extraction can regulate elbow is provided.
The utility model is realized by following technological scheme, a kind of gas extraction can regulate elbow, structure comprises elbow block set, bulb pipe, the bulbous end of bulb pipe is placed in the block set of elbow block set, be provided with sealing between the bulbous end of bulb pipe and the block set, be provided with external member in the bulbous end of bulb pipe.
(1) after elbow, assembly assembled in advance, ball rod was that the swing of 40 ° of cone angles can be done along shaft axis in the center with the centre of sphere, i.e. maximum angle ± 20 ° adjusted of elbow, with solve in the rib extraction bore angle and hole between the uneven problem of spacing.
(2) regulate take out in elbow and the wall mode that being connected of real estate management and gas extraction main pipe all adopts end cap to compress the flower bud RunddichtringO connect, fixing and seal.Installation, convenient disassembly, quick, manual operations can realize, need not to add setting tool.
(3) the elbow sealing of regulating elbow realizes that by primary seal and auxiliary seal twice O RunddichtringO primary seal closely contacted with the ball seat arc surface all the time when ball rod was swung in the cone angle of ± 20 ° scope; Auxiliary seal then is fixed between the ball seat enclosing cover, not only can prevent that coal dust from infiltrating, and plays the reliability of double seal simultaneously again.
Spherical movable joint is adopted in the joint of adjusting elbow described in the utility model, and adds two seals and be implemented in and regulate in the several angle scope and can also guarantee sealing effect.The mode that so just can adopt gas extraction to regulate elbow is come the angle and distance of the opinion in adjustment hole and hole.The difference of different distance between the different amount of the boring of being bored and boring to adapt in the crossheading.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1-bulb pipe, 2-external member, 3-sealing, 4-elbow block set
Embodiment
As schematically shown in Figure 1, a kind of gas extraction can regulate elbow, structure comprises elbow block set 4, bulb pipe 1, the bulbous end of bulb pipe 1 is placed in the block set of elbow block set 4, be provided with sealing 3 between the bulbous end of bulb pipe 1 and the block set, be provided with external member 2 in the bulbous end of bulb pipe 1.
The block set of described elbow block set 4 is made up of two fasteners up and down, and two fasteners connect by bolt and nut.Can earlier fastener be taken apart during assembling, again the bulb end be entangled.
Have the following advantages specifically:
1, effectively prevents and treats the leakage of the toxic and harmful in the gas drainage under suction process, guarantee the safe and reliable of extraction operation.
Because the coal gas outburst amount is big under the highly gassy mine, negative pressure is just big in the pipeline that causes in the extraction process, usually the method that adopts is (such as common plastics tube, common PE pipe, high-pressure rubber pipe etc., bundle to realize to connect with iron wire) and easily leak out the toxic and harmful such as gas, cause when gas density increases in the crossheading, because the very fast iron wire with the binding pipeline of the flow velocity of gas etc. does not possess fire-retardant, anlistatig object friction and produces easily electric spark in the extraction process, causes security incident.
The material that the utility model adopts is fire-retardant anti-, static PE, adds multiple additives; Two seals is adopted in the joint junction, and pipeline junction adopts flower bud RunddichtringO and institute's connecting pipe to compress by end cap and screws up, and easy to connect, quick, sealing property is reliable.
2, solve because the fitting operation problem that the difference of distance is brought between dip angle of hole and the Kong Yukong.
Regulate elbow and can in the scope centered by the centre of sphere, do 40 ° of coning angle swings, be maximum angle ± 20 ° adjusted of elbow, adapt to because the fitting operation problem that the difference of distance is brought between dip angle of hole and the Kong Yukong makes the ability at product adaptation scene stronger.
3, solve pipeline easily by dust, coarse coal grain blockage problem.
It is identical with internal diameter of the pipeline to regulate the internal diameter that the elbow of elbow adopts, and is Φ 40mm, dust is being arranged, when coal cinder stops up elbow, manually breaking off with the fingers and thumb in the elbow regulation range and can dredge blocking pipe under several.
4, installation, easy to operate is quick.
Whole erection process hand-tight make-up is regulated the termination nut at elbow two ends, can finish fitting operation.Realize sealing effect by taking out real estate management's compacting in the flower bud RunddichtringO in the nut of termination and the institute's connecting wall.All operations only needs workman's hand-tight make-up to finish, and need not additional means, and easy to operate, quick, sealability is reliable.
