Abstract
The utility model belongs to the technical field of pipeline transportation, which discloses a downhole gas exhaust pipe for a coal mine. The utility model adopts the technical scheme that the downhole gas exhaust pipe for a coal mine comprises a polyethylene pipe body, wherein at least one steel wire braiding layer is arranged in the pipe wall of the pipe body. The downhole gas exhaust pipe for a coal mine provided by the utility model can enhance the pressure resisting performance, the impact resisting strength and the flexibility of the exhaust pipe via the arrangement of the steel wire braiding layer, dead fold and fracture can not happen, and the service life of the exhaust pipe is prolonged.
Description
Technical field
The utility model belongs to the pipe transportation technology field, relates in particular to the gas drainage under suction pipe that uses under a kind of coal mine.
Background technology
At present, during with the outside extraction of gas under the coal mine, polyethylene pipe is widely used owing to its good antistatic, stretch-proof and fire resistance, but because it is withstand voltage, impact strength and pliability are relatively poor, when long distance is carried, easily make pipeline produce dead folding or fracture, cause conveying circuit to interrupt, form accident potential.
The utility model content
The purpose of this utility model just provides a kind of underground mine use gas drainage under suction pipe that is difficult for producing dead folding or fracture when carrying gas.
The technical scheme that the utility model underground mine use gas drainage under suction pipe adopts is: comprise the polyethylene body, be provided with one deck wire braid at least in the tube wall of described body.
Its additional technical feature is: the wire of described wire braid is an open weave; Described wire braid is positioned at the tube wall center; Described wire braid is near the inwall of tube wall; Described wire braid is near the outer wall of tube wall.
Underground mine use gas drainage under suction pipe provided by the utility model compared with prior art, has following advantage: the wire braid is set in the tube wall of releasing pipe body, because the wire braid plays the effect of strengthening lining, make withstand voltage, the impact strength and the pliability of releasing pipe strengthen greatly, thereby solved the generation of dead folding and phenomenon of rupture, improved the application life of releasing pipe greatly.
Description of drawings
Accompanying drawing is the structural representation of the utility model underground mine use gas drainage under suction pipe.
The specific embodiment
Be described in further details below in conjunction with the structure of accompanying drawing the utility model underground mine use gas drainage under suction pipe.
As shown in the figure, the utility model underground mine use gas drainage under suction pipe comprises polyethylene body 1, be provided with latticed wire braid 3 in the tube wall 2 of body 1, wire braid 2 can be positioned at the center of tube wall 2, also can be near the inwall 4 or the outer wall 5 of tube wall 2.In use, because wire braid 3 is arranged, make not flexible discounting of releasing pipe and withstand voltage, shock resistance.
Claims (5)
1, underground mine use gas drainage under suction pipe comprises the polyethylene body, it is characterized in that: be provided with one deck wire braid at least in the tube wall of described body.
2, underground mine use gas drainage under suction pipe according to claim 1, it is characterized in that: the wire of described wire braid is an open weave.
3, underground mine use gas drainage under suction pipe according to claim 1 and 2, it is characterized in that: described wire braid is positioned at the tube wall center.
4, underground mine use gas drainage under suction pipe according to claim 1 and 2 is characterized in that: described wire braid is near the inwall of tube wall.
5, underground mine use gas drainage under suction pipe according to claim 1 and 2 is characterized in that: described wire braid is near the outer wall of tube wall.
