Abstract
The utility model discloses a back surface argon filling device for the welding of a stainless steel pipe of a boiler. The device comprises a pipe body (1). The rear part of the pipe body (1) is fixedly connected with a handle (2). A flange (3) is formed on the pipe body (1). A chuck plate (4) is inserted into the pipe body (1). A rubber sealing ring (5) is clamped between the flange (3) and the chuck (4). The flange (3) and the chuck (4) are fixed together through a bolt. During the butt welding of two stainless steel pipes, the back surfaces of the two butt-welded stainless steel pipes are protected by argon, and the peroxidation phenomenon of a welding spot is avoided.
Description
Technical field:
The utility model relates to welding auxiliary equipment technical field, during more specifically to a kind of boiler stainless steel tube welding, is the device of stainless steel tube back filled argon.
Background technology:
Existing boiler in process of production, some stainless steel bodys that form boiler need to be welded and fixed together by argon arc welding.If in welding process, to the stainless steel body inwall applying argon gas of two docking, then can not form solder joint peroxide phenomenon, so that the service life of solder joint is short, solder joint is defective.
The utility model content:
The purpose of this utility model is exactly the deficiency for prior art; and provide the boiler stainless steel tube to weld the back filled argon device; it can be when two stainless steel tube docking welding; two the butt-welded stainless steel tube back sides that adequately protect are subjected to argon shield, and are unlikely to make solder joint to produce the peroxide phenomenon.
Technology solution of the present utility model is as follows:
Boiler stainless steel tube welding back filled argon device comprises body, and the rear portion of body is fixedly connected with handle, form ring flange on the body, the chuck sleeve is on body, and rubber seal is clamped between ring flange and the chuck, and ring flange and chuck are bolted on together.
On the described body suction nozzle is installed, suction nozzle connects argon gas, and the outlet nozzle of body is taper.
The beneficial effects of the utility model are:
1, it can be when two stainless steel tube docking welding, and two the butt-welded stainless steel tube back sides that adequately protect are subjected to argon shield, and are unlikely to make solder joint to produce the peroxide phenomenon.
2, the internal diameter size of its rubber seal stainless steel tube that can weld is as required changed at any time, can adapt to the docking welding of plurality of specifications stainless steel tube.
3, it is furnished with handle, when the staff operates the utility model is put into stainless steel tube and takes out all very convenient.
Description of drawings:
Fig. 1 is structural representation of the present utility model
Structural representation when Fig. 2 is the utility model use
Among the figure: 1, body; 2, handle; 3, ring flange; 4, chuck; 5, rubber seal; 6, suction nozzle; 11, outlet nozzle.
The specific embodiment:
Embodiment: see shown in Fig. 1,2, boiler stainless steel tube welding back filled argon device, comprise body 1, the rear portion of body 1 is fixedly connected with handle 2, form ring flange 3 on the body 1, chuck 4 sleeves are on body 1, and rubber seal 5 is clamped between ring flange 3 and the chuck 4, and ring flange 3 and chuck 4 are bolted on together.
On the described body 1 suction nozzle 6 is installed, suction nozzle 6 connects argon gas, and the outlet nozzle 11 of body 1 is taper.
Operation principle: as shown in Figure 2; two stainless steel tubes are when docking is welded; the utility model is inserted in the stainless steel tube; allow rubber seal 5 and stainless steel inside pipe wall closely cooperate; argon gas enters from suction nozzle 6; the back side at the solder joint place of the stainless steel tube of such two docking just has been subject to the protection of argon gas, is unlikely to occur solder joint peroxide phenomenon.
