Description
Technical field:
This utility model relates to pipeline welding technical field of operation, particularly to a kind of outside pipeline argon filling
Protection device.
Background technology:
Argon arc welding, is to use argon as a kind of solder technology of protective gas.Logical excessive current makes wlding exist
Formed molten bath by being melted into liquid on weldering base material, make to be welded metal and wlding reaches a kind of of metallurgical binding and welds
Technology, owing to constantly serving argon in welding in high-temperature fusion, makes wlding can not contact with the oxygen in air,
Thus prevent the oxidation of wlding, therefore can be with soldering stainless steel, ferrum class five metals metal.
Before argon arc welding welding, butt welding mouth is needed to carry out hermetically sealed protection, to realize argon concentration in pipeline
Requirement.In conventional work progress, general employing adhesive tape or blank sheet of paper enter around the weld bond mode of a week
Row seals.Although the method is simply effective, but also leaves hidden danger.First, adhesive tape or blank sheet of paper are in high warm
Produce fusing or burning under arcing, easily cause the burning of normal welding operator's medicated clothing or scald；Its
Secondary, if melting or the residue that burns is doped in weld metal, increasing the quantity of the shortcoming of weld bond, improve
There is the probability of defect, then affect weld bond qualification rate.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of outer protection device for pipeline argon filling, should
Device achieves safety simple to operate, it is to avoid burn personnel's accident occurs, and does not affect welding quality, improves argon
Arc-welding first-time qualification rate, can infinitely reuse, and reduces use cost, reduces the consumption of argon, joint
About cost.Overcoming existing argon arc welding uses adhesive tape or blank sheet of paper sealing to there is potential safety hazard, impact welding
Quality, frequently consumes adhesive tape or blank sheet of paper, and use cost is high, the deficiency that argon consumption is big.
Technical solution adopted in the utility model is: a kind of outer protection device for pipeline argon filling, including close
Envelope clip；Sealing clamp gap two ends are connected to connecting plate, are respectively connected with lock outside two connecting plates
Jack panel, adjusting screw rod is machined with the external screw thread of 50-100mm length, adjusting screw rod and two locking nut spiral shells
Stricture of vagina connects, and two locking nut female threads are oppositely oriented, and sealing clamp width is not less than 100mm, sealed card
Hoop side opening grooved hole, slotted eye width is more than 2 times of weld widths.
The beneficial effects of the utility model are: this utility model safety simple to operate, it is to avoid burn personnel occur
Accident, does not affect welding quality, improves argon arc welding first-time qualification rate, can infinitely reuse, and reduction makes
With cost, reduce the consumption of argon, cost-effective.
Accompanying drawing illustrates:
The utility model is described in more detail with detailed description of the invention below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As it is shown in figure 1, a kind of outer protection device for pipeline argon filling, including sealing clamp 1；Sealing clamp
1 gap two ends are connected to connecting plate 3, are respectively connected with locking nut 5 outside two connecting plates 3, adjust
The external screw thread of 50-100mm length it is machined with, between adjusting screw rod 4 and two locking nuts 5 employings on joint screw rod 4
Gap fit system is threaded, and two locking nut 5 female threads are oppositely oriented, to reach to use adjusting screw rod 4
Clamping or the effect of relaxation it is capable of during regulation；The interior circular diameter of sealing clamp 1 should be joined with soldered caliber
Set, interior circular diameter is more than being advisable by welded tube external diameter 4-6mm, and sealing clamp 1 width is not less than 100mm, close
Envelope clip 1 side opening grooved hole 2, slotted eye 2 width is more than 2 times of weld widths.
During use, in test specimen group to after complete, by this utility model from one end of pipeline along outer wall set,
Slotted eye 2 centrage is made with group, gap center line to be essentially coincided.Adjusting adjusting screw rod 4 makes sealing clamp 1 firm
Just block by weldering test specimen so that it is will not come off, shift, and sealing clamp 1 can be made by weldering test specimen circumference
Rotate along weld seam.In weldering test specimen, rush argon, then carry out argon arc welding operation.Treat slotted eye 2 arc length
Inside weld argon arc welding is complete, rotates in a circumferential direction sealing clamp 1 along by weldering test specimen, and keep slotted eye 2 centrage with
Gap center line is essentially coincided by group.Proceed argon arc welding to operate until argon arc welding terminates.
It is understood that above with respect to specific descriptions of the present utility model, be merely to illustrate this utility model
And it being not limited to the technical scheme described by this utility model embodiment, those of ordinary skill in the art should
Work as understanding, still this utility model can be modified or equivalent, to reach identical technique effect；
Needs are used, all within protection domain of the present utility model as long as meeting.
