Abstract

The utility model discloses a socket argon arc welding pipe fitting, which comprises a pipe fitting (11), a socket straight pipe (12) and a socket retardant slope (13). The socket retardant slope (13) is arranged between the socket straight pipe (12) and the socket retardant slope (13); the inner diameter of the socket straight pipe (12) is greater than that of the a pipeline (18); and the socket straight pipe (12) can be sleeved in the pipeline (18) and a clearance (17) is reserved between the socket straight pipe (12) and the pipeline (18). Through the socket argon arc welding pipe fitting of the utility model, the working efficiency can be improved, the welding cost can be reduced and the construction quality can be effectively guaranteed.

Description

A kind of socket joint argon arc welding pipe fitting
Technical field
The utility model relates to the welded tube field, relates in particular to a kind of socket joint argon arc welding pipe fitting.
Background technique
At present, common weld-end fittings mainly is to adopt " dock " cold working pipe fitting in the stainless steel feedwater piping is used, weld-end fittings is consistent with pipe diameter, before construction, must both roots of two docking ports be carried out respectively docking behind the groove, butt joint is " V " shape, doses the stainless steel welding stick fusion during welding and form in " V " shape butt joint.Must be before the welding in the fixing welding again of docking port place spot welding, simultaneously, the butt joint pipe fitting inner wall need lead to inert gas shielding metal bath when welding, makes it not be subjected to air oxidation.But, carry out root groove at the construction field (site) to two docking ports, need cost a lot of money the time inefficiency.And two also need a ventilation body protection operation to the weld-end fittings inwall, cause loaded down with trivial details, the cost height.
The model utility content
The technical problems to be solved in the utility model provides a kind of socket joint argon arc welding pipe fitting, and it is big to spend the time when being intended to solve weld-end fittings welding common in the prior art, inefficiency, welding cost height.
In order to solve the technical problem of above-mentioned logical weld-end fittings, the utility model adopts following technological scheme:
A kind of socket joint argon arc welding pipe fitting comprises pipe fitting, and bellmouth straight tube and bellmouth delay Yan Po, is provided with the slow Yan Po of bellmouth between described pipe fitting and the bellmouth straight tube, and the internal diameter of described bellmouth straight tube is bigger than the internal diameter of pipeline, can pack into pipeline, and remaining seam.
The angle that forms between slow Yan Po of described bellmouth and the bellmouth straight tube is the obtuse angle.
The joint of slow Yan Po of described bellmouth and bellmouth straight tube is curved.
Socket joint argon arc welding pipe fitting of the present utility model can be increased work efficiency, and reduces welding cost, and can effectively guarantee construction quality.

Among the figure: 1. butt welding pipe fitting, 2. pipeline, 3. groove, 4. argon arc welding welding gun, 5. metal bath, 6. welding wire, 7. tracheae, 8. gas tool, 11. pipe fittings, 12. bellmouth straight tubes, 13. bellmouths delay Yan Po, 14. angle, 15. argon arc welding welding guns, 16. fused metals, 17. seams, 18. pipelines.
Embodiment
Embodiment one
Common weld-end fittings of the prior art as shown in Figure 1, comprises butt welding pipe fitting 1, pipeline 2, and both need groove before welding, form groove 3, form " V " shape butt joint.
Its welded structure schematic representation during welding, is dosed stainless steel welding stick 6 as shown in Figure 2 in " V " shape butt joint, be welded with 4 fusions of argon arc welding welding gun.Simultaneously, when welding, need protect metal bath 5 by gas tool 8 and the logical inert gas of tracheae 7 feedings, make it not be subjected to air oxidation the inwall of weld-end fittings.
The socket joint argon arc welding pipe fitting of this embodiment as shown in Figure 3, comprises pipe fitting 11, and bellmouth straight tube 12, bellmouth delay slope 13.Be provided with bellmouth between pipe fitting 11 and the bellmouth straight tube 12 and delay slope 13, the angle 14 that described bellmouth delays to form between slope 13 and the bellmouth straight tube 12 is the obtuse angle, and bellmouth to delay the joint of slope 13 and bellmouth straight tube 12 curved.Curved purpose of design is in order to prevent in welding, to insert the pipe fitting expanded by heating in the bellmouth straight tube 12, causing bellmouth straight tube 12 to break.
Wherein, the internal diameter of described bellmouth straight tube 12 is bigger than the internal diameter of pipe fitting 11, can pack into pipeline 18, and remaining seam 17, and seam 17 can play and desire the gas-filled protective effect.
The welded structure schematic representation is inserted into pipeline 18 in the bellmouth straight tube 12 of socket joint argon arc welding pipe fitting of this embodiment as shown in Figure 4, only needs to remove the burr of socket joint argon arc welding pipe fitting, does not need groove.After the insertion, in both joints, the metal of the port edge of bellmouth straight tube 12 directly adopts argon arc welding welding gun 15 to carry out melting welding, utilize the metal of the port edge of bellmouth straight tube 12 to replace welding wire 6, thereby make the metal of port edge of bellmouth straight tube 12 and the metal of pipeline 18 be fused into one.When the metal of the port edge of bellmouth straight tube 12 when forming fused metal 16 by welding with the metal of pipeline 18; as long as the construction process of getting hold of; fused 16 on metal can not penetrate socket joint argon arc welding pipe fitting inner wall; oxidized because fused metal 16 does not contact ambient air, therefore in welding process, need not do the protection of inner tube wall ventilation body.And must not carry out spot welding before the weldering and fix, pipeline 18 inserts the directly welding connection of bellmouth straight tube 12 backs.
In addition, in the welding, argon arc welding welding gun 15 and pipeline 18 angles at 45, thus can catch up with the argon gas of argon arc welding welding gun 15 ejections in the seam 17, thus prevent that fused metal 16 is oxidized.
Socket joint argon arc welding jointed tubular workpieces of the present utility model can be increased work efficiency, and reduces welding cost, and can effectively guarantee construction quality.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
