Abstract

The local argon protective device of pipeline welding, belongs to welding field, overcomes that prior art argon gas consumption is big, and inflationtime is long, the very low and less economical defect of efficiency.Its structure have argon gas hose (1), bolt (2), seal joint (3), flexible gasket one (4), escape pipe (5), venthole (6) etc.;(6) escape pipe is (5) intermediate to have venthole, both sides are provided with gasket and fix plugging structure, and (5) gas source interface is arranged in one end to escape pipe;Flexible gasket can be adjacent to sealing using rubber pad and thick sponge combination with the inner wall of the pipe of certain diameter range.(10) (9) the device is placed among the weld seam that two are waited for Coiling Welded Pipe with pulling iron wire from pipeline side by lifting lug when use;Gas source valve is opened, (6) argon gas is full of the local space formed by both sides plugging structure by venthole;Argon arc welding construction is carried out to pipe welding port at this time.The present apparatus is easy, practical, reliable, environmentally friendly, cost-effective, to pipeline base material without any damage, has very high engineering practical value.

Description

The local argon protective device of pipeline welding
Technical field
The utility model belongs to welding field, and in particular to the local argon gas protection of pipeline welding.
Background technology
When carrying out the welding of pipeline nozzle using argon arc welding technology, argon gas need to be full of in nozzle interior welds region by air Keep apart to reach the protecting effect for preventing weld seam from aoxidizing.The prior art is generally used using by two pipeline exterior side ports to be welded Blind plate is blocked, and is then protected full of argon gas in entire pipeline inner space.But this method plenum space is big, weld seam The effect of interior applying argon gas is bad, is easy to cause weld seam inner surface and is aoxidized.Secondly, argon gas consumption is big, and inflationtime is long, efficiency It is very low and less economical.
Invention content
Goal of the invention seeks to solve above-mentioned technical problem.
The utility model provides a kind of local argon protective device of pipeline welding, and structure includes:Argon gas hose 1, spiral shell Bolt 2, seal joint 3, flexible gasket 1, escape pipe 5, venthole 6, closure plate 7, flexible gasket 28, iron wire 9, lifting lug 10, Gland 11, nut 12, baffle ring 13;There are venthole 6, both sides to be provided with gasket and fix plugging structure among the escape pipe 5, Gas source interface is arranged in 5 one end of escape pipe;The gasket of both sides fixes plugging structure by bolt 2, seal joint 3, flexible gasket One 4, closure plate 7, flexible gasket 28, gland 11, nut 12, baffle ring 13 form;The flexible gasket 1, flexible sealing Pad 28 has certain compression-expansion using rubber pad and thick sponge combination, can be with the inner wall of the pipe of certain diameter range It is adjacent to sealing;Described 11 one end of gland has lifting lug 10 to connect iron wire 9, and iron wire 9 has enough intensity and taken over more than to be welded The length in road.
Application method:Argon gas hose 1 and escape pipe 5 are connected after assembling flexible gasket, passed through from pipeline side Lifting lug 10, which pulls iron wire 9 and is placed in the device, to be waited for Coiling Welded Pipe 1 and waits among the pipeline-weld of Coiling Welded Pipe 2 15;Open air source Valve, argon gas are full of the local space formed by both sides plugging structure by the venthole 6 being arranged on escape pipe 5;Argon gas at this time Discharge air reaches higher purity quickly;Start to carry out argon arc welding construction to pipe welding port;By pulling iron after the completion of welding The local argon protective device of silk dismounting pipeline welding.
The utility model has the beneficial effects that carrying out pipeline welding using the present apparatus, it is only necessary to local space argon filling is being welded, Argon gas consumption is considerably reduced, the argon filling weld preparation time in pipe is reduced;Simplicity is installed and used, and can be applicable in certain Pipeline in diameter range welds demand;Welding quality is improved, it is reusable, there is extraordinary economy.
