Abstract
The utility model relates to a welding device of a flanging of a pipeline connecting piece, which is characterized by a welding base, a ring-shaped welding pressing plate, a pressing plate cushion block and a gas delivery pipe; the middle of the welding base is provided with a ring-shaped flange; the outer side of the ring-shaped flange is provided with a ring-shaped groove; the ring-shaped welding pressing plate is arranged and connected on the welding base which is internally provided with a gas delivery channel; and one end of the gas delivery channel is communicated with the gas delivery pipe, and the other end is communicated with the ring-shaped groove. The welding device has the advantages that the use amount of welding protective gas is reduced by 60%-80%, the welding efficiency is high, the subsequent shaping procedures are reduced and the production efficiency is improved.
Description
One, technical field
The utility model relates to a kind of welder, relates in particular to a kind of welder of flange of conduit coupling.
Two, background technology
Weldering system flange (welding neck collar) is usually used in medium temperature and pressure is not high and in the pressure pipeline that corrosive medium is stronger.When corrosive medium was strong, the part of flange contact medium (flange) be materials such as corrosion resistant high-grade material such as stainless steel, and is outside then utilize the flange ring of low grade material such as carbon steel material to clamp it to seal with realization; So just can reduce the cost of whole piece pipeline.Weldering system flange (welding neck collar) because; weldering system flange all is special materials such as stainless steel or copper alloy, nickel-base alloy, Hastelloy; need the applying argon gas protection when the bottoming welding, special material such as Hastelloy more needs high-purity argon gas protection, and this has increased welding cost undoubtedly.In addition, overlap edge is easy to produce welding deformation owing to be subjected to the influence of the welding stress of angle welding, is easy to cause the sealing surface of flange to process.
Three, summary of the invention
At above-mentioned shortcoming, the purpose of this utility model is to provide a kind of can reduce the argon gas consumption, be not easy to produce the welder of flange of the conduit coupling of welding deformation.
Technology contents of the present utility model is that a kind of welder of flange of conduit coupling is characterized by it and comprises welding base, annular solder pressing plate, pressing plate cushion block and appendix; There is annular lip centre at the welding base, is provided with an annular groove in the annular lip outside; The annular solder pressing plate is installed and is connected on the welding base, is provided with gas distribution channel in the welding base, and an end of gas distribution channel is communicated with appendix, and the other end of gas distribution channel communicates with annular groove.
What the utility model was compared with prior art had is a little:
(1), the welding protection gas usage reduces 60-80% and welding efficiency height.
(2), reduced follow-up trimming, improved production efficiency.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, specific embodiment
As shown in Figure 1, a kind of welder of flange of conduit coupling is characterized by it and comprises welding base 1, annular solder pressing plate 2, pressing plate cushion block 3 and appendix 4; There is annular lip 1.1 centre at welding base 1, is provided with an annular groove 1.2 in annular lip 1.1 outsides; Annular solder pressing plate 2 is installed and is connected on the welding base 1, is provided with gas distribution channel 1.3 in welding base 1, and an end of gas distribution channel 1.3 is communicated with appendix 4, and the other end of gas distribution channel 1.3 communicates with annular groove 1.2.
Operation principle of the present utility model is: the annular lip 1.1 of welding base 1 centre is inserted in the adapter 5 that will weld flange, and the flange 6 that will weld is placed on the welding base 1 and is enclosed within takes over 5 outsides; Annular solder pressing plate 2 and at flange 6 underlay pressing plate cushion blocks 3 on press-fiting on flange 6 limits is adjusted the welded gaps 7 of weldering system flange overlap edge and adapter, to around welded gaps 7 even, annular groove 1.2 aligning welded gaps 7; Tight a bolt and 8 make annular solder pressing plate 2 compress flange 6; Spot welding is welded system flange 6 and is taken over 5, and appendix 4 input protection gases (argon gas) make protective gas spray into welded gaps 7 by gas distribution channel 1.3 owing to annular groove 1.2 simultaneously, and butt tube 5 carries out welding protection with the backing welding of flange 6.
