For realizing above purpose, the utility model has been taked following technological scheme: a kind of thin-wall stainless steel water pipe method is held the formula linkage structure, include the pipe fitting joint and the tube connector that are bonded with each other and connect, end edge at described pipe fitting joint is provided with pipe fitting flange flange along outwards turning down, end edge at described tube connector is provided with tubing flange flange along outwards turning down, and described pipe fitting flange flange and tubing flange flange position are corresponding also to be connected; Also be arranged with internal lining pipe in described pipe fitting joint, this internal lining pipe outer wall is provided with seal ring near described pipe fitting joint inwall on the internal lining pipe outer wall between described pipe fitting flange flange and the tubing flange flange; Also include the pipe fitting anchor ear that described pipe fitting flange flange and tubing flange flange are fastenedly connected.
Above-mentioned linkage structure does not have intergranular corrosion, seal ring compression ratio balance unanimity, and good airproof performance, easy to maintenance, possess reliable sealing performance, exempt from compensation, it is cold flexible that To Be Protected from Heat; Pipe fitting joint making workload is few, has saved raw material, and processing cost and installation cost are low, and the maintenance repacking is convenient; Pipe fitting joint dismounting back is reusable; Installation is efficient and convenient.
Also include fastening screw, described fastening screw is fastenedly connected described pipe fitting flange flange, tubing flange flange and pipe fitting anchor ear.
The vertical cross-section of described pipe fitting anchor ear is a V-type, and the two ends of described v-shaped tube spare anchor ear are embraced respectively and are stuck on described pipe fitting flange flange and the tubing flange flange.
The utility model compared with prior art, have following advantage: the pipe fitting of this novel Placement is few for raw materials consumption, processing is unrestricted, manufacturing procedure is few, save great amount of cost, good seal performance, its stainless-steel thin-wall pipe pipe fitting price descends, and engineering cost is reduced, and the stainless life-span is long, water quality is not subjected to secondary pollution, can make huge numbers of families drink safe water, the radiation-resistant pipeline of stainless-steel environment-friendly has great benefit to producing, living, bring benefit to society, also can produce good economic benefits simultaneously.
