Abstract
The utility model discloses a pipeline argon arc welding pipeline inner argon filling seal device, which comprises a combined plug, a connected cable chain, an argon pipe joint and a traction steel wire. The pipeline argon arc welding pipeline inner argon filling seal device can be conveniently filled in a pipeline to be welded and is closely fit with the pipeline to be welded to form a sealed space for storing argon, and pulls the combined plug outside the pipeline from one end of the pipeline through the traction steel wire and the connected cable chain after being used. The pipeline argon arc welding pipeline inner argon filling seal device can effectively reduce inner argon filling space in the pipeline, greatly reduces usage amount of argon, effectively reduces argon arc welding cost, and greatly improves argon filling protection effect in the pipeline simultaneously, thereby preventing the surfaces of metals in welded joints from being oxidized during the welding process, improving welding quality of the welded joints, and being particularly suitable for welding protection of argon arc welding of stainless steel pipelines.
Description
technical fieldthe utility model has been announced argon filling sealing device in a kind of pipeline argon arc welded tube.
background technologyargon arc welding is widely used in pipeline welding.When stainless steel pipes welds, for preventing that weld metal from oxidation reaction occurring when the high temperature, cause intercrystalline corrosion, must protect at pipe interior applying argon gas to be welded.If be all full of argon gas in pipe interior cavity, not only argon gas consumption is large, and also difficult assurance of argon concentration, causes argon gas waste, and the not enough argon arc welding quality that easily affects of argon concentration.For guaranteeing the argon concentration of inside, pipeline position to be welded, reduce argon gas use amount simultaneously, reduce argon arc welding cost, provide a kind of simple in structure, seal reliable, convenient and practical pipe interior argon filling sealing device and have important practical significance.
summary of the inventionthe purpose of this utility model be exactly to provide a kind of simple in structure, seal reliable, convenient and practical pipe interior argon filling sealing device.
The purpose of this utility model is achieved in that argon filling sealing device in a kind of pipeline argon arc welded tube; there is combination plug, connecting strand chain, tunger tube joint, traction steel wire; described combination plug is discoid; two are used in conjunction with; during use, fill in pipeline to be welded; between two combination plugs and pipeline to be welded, form a confined space that stores argon gas, from tunger tube joint, be filled with argon gas, treat weldering pipe welding port and effectively protect.
As further scheme of the present utility model, described combination plug is comprised of connecting bolt, nut, circular sponge, circular asbestos rubber pressing plate, by connecting bolt, nut, circular asbestos rubber pressing plate, circular sponge is compressed and forms an entirety.
As further scheme of the present utility model, between described two combination plugs, by connecting strand chain, be connected, after weld, by traction and the traction steel wire that is connected of combination plug, whole sealing device is pulled out pipeline from one end of pipeline.
As further scheme of the present utility model, the external diameter of described circular sponge is than the large 20-30mm of the internal diameter for the treatment of Coiling Welded Pipe, the external diameter of circular asbestos rubber pressing plate (8) is than the little 20-30mm of the internal diameter for the treatment of Coiling Welded Pipe, during use, combine plug can fill in easily pipeline to be welded and and pipeline to be welded between laminating closely, form the confined space that stores argon gas.
