Abstract
The utility model relates to a pipeline welding technique field, in particular to argon filling plugging device in welding of pipeline argon arc. Be equipped with a circular rubber and fixed through bolted connection between per two circular iron sheets of the device, circular gluey skin external directly is greater than circular iron sheet external diameter, is connected through three bracing piece between two the circular iron sheets that link together of two circular iron sheets and other that link together, is equipped with the pore of ventilating on one side of wherein on two circular iron sheets and the circular rubber. The utility model discloses a shutoff aerifys fast, and the shutoff is effectual, guarantees argon filling volume minimizing, reduces the argon gas quantity to can guarantee welding quality, the installation is dismantled conveniently, the less investment. The argon filling volume is big in having overcome present pipeline welding construction, and welding quality is poor, can not obtain the not enough of qualified weld bond.
Description
Technical field:
The utility model relates to a kind of pipeline welding technical field, particularly argon filling plugging device in a kind of pipeline argon arc welding.
Background technology:
Large-caliber stainless steel pipeline welding many employings argon arc welding back cover, because oxygen, nitrogen, hydrogen produce harmful effect to electric arc and molten bath, interior argon filling must be carried out in butt welding mouth place, isolated air, to reduce alloying element scaling loss, obtain densification, without the welding point splashed, quality is high.In existing pipeline welding, argon filling amount is large, and poor welding quality, qualified weld bond can not be obtained.
Utility model content:
The technical problems to be solved in the utility model is to provide argon filling plugging device in a kind of pipeline argon arc welding, and the arrangement achieves and can quick blocking inflate, plugging effect is good, ensure argon filling volume minimization, reduce argon gas consumption, and can welding quality be ensured, easy installation and removal, less investment.Overcome argon filling amount in existing pipeline welding large, and poor welding quality, the deficiency of qualified weld bond can not be obtained.
Technical solution adopted in the utility model is: argon filling plugging device in a kind of pipeline argon arc welding, comprises four round iron plates; Be provided with a circular rubber between every two round iron plates and be bolted fixing, circular rubber external diameter is greater than round iron plate external diameter, be connected by three support bars between two round iron plates linked together with another two round iron plates linked together, wherein two, side round iron plate and a circular rubber are provided with vent cap.
The beneficial effects of the utility model are: the utility model can quick blocking be inflated, and plugging effect is good, ensures argon filling volume minimization, reduces argon gas consumption, and can ensure welding quality, easy installation and removal, less investment.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As shown in Figure 1, argon filling plugging device in a kind of pipeline argon arc welding, comprises four round iron plates 1, be provided with the circular rubber 2 of the wear-resisting type that can change between every two round iron plates 1 and be connected and fixed by bolt 3, circular rubber 2 external diameter is greater than round iron plate 1 external diameter, be connected by three support bars 4 between two round iron plates 1 linked together with another two round iron plates linked together 1, wherein two, side round iron plate 1 and a circular rubber 2 are provided with vent cap 5, the utility model and pipeline form relative confined space and form interior argon filling space, vent cap 5 is for connecting ar gas passage, argon filling in the confined space that plugging device and pipeline form, both argon filling amount had been controlled, ensure again the effect of argon filling, and obtain qualified weld bond.Easy owing to installing, dismantling, be very applicable to Pipeline operation, save argon gas consuming cost.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
