Abstract
The utility model discloses a local argon filled gas-filling and tracking protective box in a large-size pipeline for filling protective gas-argon in process of welding the large-size pipeline, which comprises a circular gas-filling air bag. The bottom of the circular gas-filling air bag is provided with a soft closing plate that enables the bottom of the circular gas-filling air bag to be closed, the circular gas-filling air bag and the soft closing plate form a ship-shaped structure which form a closed gas-filling space together with the pipeline, a gas-filling rubber tube extends from the outside of the pipeline to the circular gas-filling air bag, and an argon-filling pipeline extends from the outside of the pipeline to the gas-filling space. The utility model has the advantages of 1, good plugging effect so as to ensure argon-filling concentration and welding quality; 2, low manufacturing cost so as to form adaptable radians according to different pipe diameters with strong interchangeability; 3, light weight, low labor-intensity of constructors and high work efficiency; and 4, adaptability to the pipeline where the constructors can enter and turn round.
Description
Technical field
The utility model relates to a kind of aerating device, relate in particular to a kind of in big specification pipeline welding process in order to fill the local applying argon gas inflation track protection box of protective gas argon gas.
Background technology
When adopting the argon arc welding soldering stainless steel, because the affinity of stainless steel and oxygen is very big, if do not take the weld seam protection measure; the weld metal at the back side is easy to oxidation in welding process; the alloying element scaling loss, and easily produce weld defect, cause the mechanical property of weld metal and corrosion resistance to descend.When the stainless steel pipes argon arc welding; for guaranteeing the welding quality of back of weld; must take effective safeguard procedures; the method of argon filling prevents the back of weld oxidation in the pipe commonly used now; general entering a pipe diameter very important person just can be adopted track protection box method argon filling; the protection box slides and positive welding is carried out synchronously, with abundant assurance welding quality.But present track protection box is generally steel, so weight is heavier, workmen's labour intensity is big in the pipeline, inefficiency; And the track protection box will customize by internal diameter of the pipeline, and interchangeability is relatively poor.
The utility model content
The utility model is at above-mentioned defective, and it is a kind of simple in structure, easy to carry and can realize local applying argon gas inflation track protection box in the good big specification pipeline of applying argon gas performance that purpose is to provide.
The technical solution of the utility model is: the utility model comprises the annular inflatable air bag, the bottom of annular inflatable air bag is if the soft shrouding of annular inflatable air bag bottom lock, annular inflatable air bag, soft shrouding form the ship shape structure and and pipeline between form a sealing plenum space, the inflation sebific duct extends to outside pipeline in the annular inflatable air bag, and the argon filling pipeline extends in the plenum space outside pipeline.
Handle is established in described soft shrouding bottom.
The utility model advantage: 1. plugging effect is good, guarantees argon filling concentration, guarantees welding quality; 2. cost of manufacture is low, can form the radian that adapts according to different tube diameters, and interchangeability is strong; 3. in light weight, workmen's labour intensity is low, high efficiency; 4. the utility model is suitable for the pipeline that the workmen can enter and can turn round.

The specific embodiment
Inflation track protection box 1 of the present utility model is made by the airtight single face material of aluminizing; comprise annular inflatable air bag 6; the bottom of annular inflatable air bag 6 is if the soft shrouding 7 of annular inflatable air bag 6 bottom locks; annular inflatable air bag 6, soft shrouding 7 form the ship shape structures and and pipeline 4 between form a plenum space; inflation sebific duct 2 extends in the annular inflatable air bag 6 outside pipeline 4; argon filling pipeline 3 extends in the plenum space outside pipeline 4, and the utility model is established handle 8 in soft shrouding 7 bottoms simultaneously.
Below the course of work of the present utility model is described: the utility model assembling before pipeline 4 weldering is qualified afterwards seals weld seam with adhesive tape 5, and stays an osculum.Inflate to the annular inflatable air bag 6 of inflation track protection box 1 during use; should notice that the blowing pressure can not be too big; grasp handle 8, inflation track protection box 1 is closely contacted with the pipeline 4 of weld, between inflation track protection box 1 and weld seam, form the sealing plenum space.By argon filling pipeline 3 argon filling in the sealing plenum space, after argon gas reaches concentration, carry out backing welding and connect, the workmen progressively tears the adhesive tape 5 of soldering and sealing seam simultaneously off, until finishing backing welding by the synchronous mobile aeration track protection of speed of welding box 1 in the pipe.When inflation track protection box 1 was made, the aluminize plating aluminium foil surface of material of airtight single face should be towards weld seam.The airtight single face of making inflation track protection box 1 is aluminized material should be able to be high temperature resistant, and should be the material that does not fire.
Claims (2)
1. local applying argon gas inflation track protection box in the big specification pipeline; it is characterized in that; comprise the annular inflatable air bag; the bottom of annular inflatable air bag is if the soft shrouding of annular inflatable air bag bottom lock; annular inflatable air bag, soft shrouding form the ship shape structure and and pipeline between form a sealing plenum space; the inflation sebific duct extends to outside pipeline in the annular inflatable air bag, and the argon filling pipeline extends in the plenum space outside pipeline.
2. local applying argon gas inflation track protection box is characterized in that handle is established in soft shrouding bottom in the big specification pipeline according to claim 1.
