Abstract
The utility model discloses a connecting tube for thin-wall metallic duct. The tube is a hollow metallic tube with malleability. The end of the tube body uplifts in radial direction. The protrusion is folded to a flat retaining ring. With the structure, the metallic tube and the metallic carrier ring make up of a multiplayer rigid sealed structure. The utility model has the advantages of resistance to elevated temperature, high pressure, shock resistance, non-spin and non-separation. The tube is simple and firm in connection, as well as good in sealed performance.
Description
Technical field
The utility model relates to the field of liquid, air shooter, particularly the metal tube of rigid seal connection.
Background technique
Metal pipe is in many-sided extensive uses such as water supply, heat supply, air feed, chemical delivery, and except that galvanized pipe commonly used, copper pipe, at present common also have line plastic-steel tube, plastic-coated steel, inner liner stainless steel composite pipe etc.These metal pipes are connecting the way that often will adopt the damage pipe end when using, promptly open hinge worm tooth or open channels, because worm tooth and groove have certain height and degree of depth requirement, for guaranteeing strength character and the sealability after tubing connects, the wall thickness of tubing just need be reserved enough surpluses for the processing of pipe end during production, cause the whole wall thickness of tubing to be much higher than the size that real fluid pressure is set, cause a large amount of wastes of metallic material, cost of production also increases thereupon.
The model utility content
The purpose of this utility model be to propose a kind ofly to reduce pipe thickness, be easy to connect, be connected firmly, the thin-wall metal of good seal performance carries connecting tube, fundamentally reduces the material consumption amount of metal pipe, reduce cost.
The technical solution of the utility model is: a kind of thin-wall metal is carried connecting tube, and body is the hollow metal tube with certain ductility, and radially swell the body end, and bump pad is built up a flat back-up ring.Further, " n " shape of being close to before and after the cross section of flat back-up ring is, its thickness is 2 times of body wall thickness.
Such tubing, the just practicable rigid seal of pipe fitting, packing ring, pipe cap connects as long as be connected, need not carry out damaging processing to pipe end, the wall thickness of tubing can directly calculate setting according to hydrodynamic pressure and corrosion resistance, heat resistance etc., need not reserve the cutting surplus.It is thin to have light weight, wall, is connected firmly, good airproof performance, and advantages such as easy to connect are installed.
Description of drawings
Fig. 1 is a schematic representation of the present utility model;
Fig. 2 is the schematic representation of the utility model and connection pipe fitting assembly.
Embodiment
Referring to Fig. 1, Fig. 2, present embodiment adopts stainless steel hollow tube 1, radially pressurize in port at tubing 1, the diffusion protuberance, bump pad is built up a flat back-up ring 11, the periphery of flat back-up ring 11, root and tubing 1 seamlessly transit, and " n " shape of being close to before and after the cross section of flat back-up ring 11 is is so that cooperate with connection pipe fitting 2, packing ring 3, pipe cap 4 respectively.When tubing 1 is connected with connection pipe fitting 2 assemblies, pipe cap 4 is packed in the tubing 1 dorsad, pressurization, diffusion pipe end form protuberance, are built up back-up ring 11 at bump pad again, packing ring 3 are packed into back-up ring 11 the place aheads again, pipe end is inserted in the connection pipe fitting 2, the interior step 22 of tubing 1 mouth of pipe roof pressure connection pipe fitting 2, pipe cap 4 internal threads are screwed into connection pipe fitting 2 outside threads, like this, press between flat back-up ring 11 and packing ring 3, pipe cap 4, the interior step 22 and be fastened as one, the connection of formation multilayer rigid seal structure.
Certainly, only enumerate a kind of preferable mode here, the protection domain that other are equal to, the structure of tubing roughly the same all should belong to this patent repeats no more here.
Claims (2)
1, a kind of thin-wall metal is carried connecting tube, and body is the hollow metal tube with certain ductility, it is characterized in that: radially swell the body end, and bump pad is built up a flat back-up ring.
2, connecting tube according to claim 1 is characterized in that the cross section of flat back-up ring is " n " shape that front and back are close to, and its thickness is 2 times of body wall thickness.
