Abstract
The utility model relates to a pipeline in-soldering seam shielding-gas sealing device which mainly solves the problems that the existing gas shield sealing device is easy to leak, easy to be damaged and difficult to guarantee the content of the shielding gas, and is characterized in that a marching wheel (2) is arranged on the lower part of a barrel body (1). Inflated tyres (3) surround and are fastened on the two outer ends of the barrel body (1). The inflated tyres (3) and a connecting pipe (4) are communicated with an air source. The wall of the barrel body (1) between the two inflated tyres (3) is communicated with a shielding gas inflation tube (5) which is communicated with the shielding air source. The pipeline in-soldering seam shielding-gas sealing device has the advantages of good effect of seal and easy operation.
Description
Technical field:
The utility model relates to protective gas sealer in oil field pipe transportation art used welding corollary apparatus, the especially pipe welding seam.
Background technology:
Carry in the welding procedure at oil field pipe; especially in the Steel Tube Special welding,, when the bottoming welding, need the butt welded seam back side to carry out gas shield in order to guarantee welding quality; preventing the back of weld oxidation, and when welding, need use sealing device that gas is protected.The sealing device structure that uses is very simple at present, seals with rubber slab or cardboard, so just exists gas and easily leaks, and causes unnecessary waste; At the push-and-pull sealing device when the weld seam, because of the weld seam temperatures involved fragile; The protective gas content at welding bead place is not easy to guarantee, influences welding quality.
The utility model content:
Easily leak in order to overcome existing gas shield sealing device, fragile and deficiency that protective gas content is not easy to guarantee; the utility model provides protective gas sealer in a kind of pipe welding seam, and the protective gas sealer has the characteristics simple to operate that really reach well that seal in this pipe welding seam.
The technical solution of the utility model is: the protective gas sealer comprises staving in this pipe welding seam; down with the outer two ends of the staving of travel wheel around intrinsic air tyre; the air tyre tube connector communicates with source of the gas, is communicated with on the barrel body wall between two air tyres and the protective gas gas tube of protecting source of the gas to communicate.
The house steward that communicates with tube connector and protective gas gas tube is nested inside and outside the crosswise fixed in the above-mentioned staving respectively.
The beneficial effect that the utlity model has is: protective gas sealer in this pipe welding seam since outside staving two ends around intrinsic air tyre; be communicated with on the barrel body wall between two air tyres and the protective gas gas tube of protecting source of the gas to communicate; by two air tyres protective gas is sealed between outer two air tyres of staving; easily leak with regard to having solved protective gas like this, sealing device is fragile and the content of protective gas is not easy to guarantee and cause unnecessary waste; thereby raising sealing effectiveness; and simple to operate, guaranteed welding quality.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-staving among the figure, 2-travel wheel, 3-air tyre, 4-tube connector, 5-protective gas gas tube, house steward 6-.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By shown in Figure 1; the protective gas sealer comprises staving 1 in this pipe welding seam; 1 time band of staving travel wheel 2; staving 1 outer two ends are around intrinsic air tyre 3; be communicated with protective gas gas tube 5 on staving 1 wall that two air tyres are 3; the house steward 6 who is nested inside and outside the crosswise fixed and communicates in the staving 1 with source of the gas, air tyre 3 communicates with source of the gas by pipe in tube connector 4 and the house steward 6 successively, and protective gas gas tube 5 communicates with source of the gas by house steward's 6 outer tubes.
During actual the use; this device is put into pipeline to be welded; make weld seam place 3 of two air tyres by moving this device; inflate to two air tyres 3 by source of the gas again; two air tyres 3 are closely touched mutually with pipeline, at this moment by the protective gas source of the gas by house steward 6 and manage 5 and stop to the ring cavity filling of 3 of two air tyres protection gas.Easily leak with regard to having solved protective gas like this, sealing device is fragile and the content of protective gas is not easy to guarantee and cause unnecessary waste, thereby improve sealing effectiveness, and simple to operate, guaranteed welding quality.
Claims (2)
1, protective gas sealer in a kind of pipe welding seam; comprise staving (1); it is characterized in that: the outer two ends of staving (1) of band travel wheel (2) are around intrinsic air tyre (3) down; air tyre (3) tube connector (4) communicates with source of the gas, is communicated with and the protective gas gas tube (5) of protecting source of the gas to communicate on staving (1) wall between two air tyres (3).
2, protective gas sealer in the pipe welding seam according to claim 1 is characterized in that: the house steward that communicates (6) with tube connector (4) and protective gas gas tube (5) is nested inside and outside the crosswise fixed in the staving (1) respectively.
