Description
Technical field
This utility model relates to a kind of mosaic reinforcement spiral welded pipe, belongs to gas drainage pipeline technical field.
Background technology
At present, coal bed methane extraction pipe has following several pipeline: plastic-coated steel is moulded in polyethylene tube, polyvinyl chloride pipe, common steel tube, leaching.Though polyethylene, polrvinyl chloride are corrosion-resistant but its anti-flammability and antistatic behaviour are extremely difficult to, even if reaching also because its additive too much affects pipe workpiece quality;Common steel tube is the most corrosion-resistant;Plastics coated tube is difficult to solve and exist be coated with plastics problem easy to fall off on antistatic.Current stainless steel tube is high because of its cost, not application in gas drainage system of coal mine, but stainless steel tube has the irreplaceable advantage of other pipeline, one: stainless steel tube can thoroughly solve the fire-retardant and anlistatig requirement of pipes for mining, its two: solved the most corrosion resistant problem of common steel tube by the corrosion resistance of ten rustless steels itself.
Thin-walled reinforcement type spiral welded pipe in existing market at present, setting due to reinforcement, coal seam water is easily stockpiled in reinforcement groove, cause the corrosion that tubing causes because corrosivity coal seam water accumulates, affect service life, the groove of pipe material inner wall affects the smoothness of pipe material inner wall simultaneously, affects drainage efficiency；And existing spiral welded pipe mainly uses welding manner to be attached, welding inconvenience, and be unfavorable for safeguarding.
Utility model content
For solving the technical problem that prior art exists, this utility model provides a kind of simple in construction, easy to use, the built-in inner supporting body of reinforcement, strengthen the ring stiffness of body, improve the smoothness of inboard wall of tube body, reduce the inboard wall of tube body mosaic reinforcement spiral welded pipe to conveyance fluid resistance.
For achieving the above object, the technical scheme that this utility model is used is mosaic reinforcement spiral welded pipe, including: the body being welded by steel plate helix-coil, at least spiral reinforcement rolled from inside to outside it is provided with on described body, being provided with inner supporting body in the groove of described reinforcement, described inner supporting body is with inboard wall of tube body at grade.
Preferably, the cross section of described inner supporting body is circular, semicircle or hollow semicircular.
Preferably, one end of described body is provided with grafting boss, and the other end is provided with grafting groove, described grafting boss is provided with sealing gasket, is provided with sealing ring in grafting groove, and the two ends of body are provided with adpting flange.
Compared with prior art, this utility model has following technical effect that this utility model arranges inner supporting body in reinforcement, strengthen the ring stiffness of existing reinforcement body, on the premise of meeting negative pressure work, it is equally applicable to the conveying of barotropic fluid, adds the stability of reinforcement, effectively avoid the generation of body metaboly, improve the smoothness of inboard wall of tube body simultaneously, reduce the inboard wall of tube body resistance to conveyance fluid.
Additionally, body uses grafting to coordinate, flange is fixing connects, easy to connect, and good sealing effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of inner supporting body in this utility model.
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As shown in Figure 1 and Figure 2, mosaic reinforcement spiral welded pipe, including: the body 1 being welded by steel plate helix-coil, at least spiral reinforcement 2 rolled from inside to outside it is provided with on body 1, inner supporting body 3 it is provided with in the groove of reinforcement 2, the cross section of inner supporting body 3 is circular, semicircle or hollow semicircular, and inner supporting body 3 is with body 1 inwall at grade.So inner supporting body has just blocked the groove that inboard wall of tube body reinforcement is formed, inboard wall of tube body is made to smooth, be conducive to fluid flowing, reduce fluid flow resistance, the inner supporting body simultaneously blocked stockpiles coal seam water problem in solving reinforcement groove, the corrosion that causes because corrosivity coal seam water accumulates of avoiding tubing, improves tubing service life, reduces owing to reinforcement groove affect the noise of air-flow formation；And enhance the ring stiffness of body, improve the stability of body, effectively avoid the generation of body metaboly.
Additionally, one end of body 1 is provided with grafting boss 4, the other end is provided with grafting groove 5, and grafting boss 4 is provided with sealing gasket 6, is provided with sealing ring 7 in grafting groove 5, and the two ends of body 1 are provided with adpting flange 8.Body is attached by head and the tail grafting, then it is attached by flange, grafting groove is enclosed within grafting boss, root at grafting groove arranges sealing ring, formation first seals, and arranges sealing gasket and form second sealing between two flanges, and double-layer seal ensures the sealing property of body, and it is easy to connect, it is simple to later maintenance and maintenance.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, in the range of all should wrapping in this utility model.
Claims (2)
1. mosaic reinforcement spiral welded pipe, including: the body being welded by steel plate helix-coil, it is characterized in that: on described body, be provided with at least spiral reinforcement rolled from inside to outside, being provided with inner supporting body in the groove of described reinforcement, described inner supporting body is with inboard wall of tube body at grade；
