Abstract
High alloy small -bore pipe welding argon filling device is including the little copper pipe in let in the argon gas to the inside pipe wall, the argon gas cross valve of leading electric nozzle, argon gas leather hose and being used for linking to each other with the argon gas pipeline, its characterized in that the one end of little copper pipe run through and lead electric nozzle, stretch into the argon gas leather hose, the other end has a tip of ventilating of flat shape, the one end of argon gas leather hose with lead the sealed suit of electric nozzle, the other end and argon gas cross valve sealing connection. The utility model discloses a high alloy small -bore pipe welding argon filling device, simple structure, the operation is simple and easy, possibly effectively practice thrift the argon gas.
Description
Technical field
This utility model relates to a kind of high alloy small-bore pipe welding argon-filling device, to inwall applying argon gas at groove when high-alloy steel small-bore pipe welds.
Background technology
The system bank of tubes such as high temperature reheater, high temperature superheater and pendant superheater use high alloy steel the most in a large number; owing to these materials are when welding, back of weld must effectively protect and just be avoided that root oxidation, obtains good appearance of weld and ensure the mechanical performance of welding point.
Two kinds of traditional back of weld argon filling modes have two kinds: the first, pipeline entirety argon filling--in advance pipe ends closure is got up, in alloy pipe to be welded, be filled with argon to get rid of inner air tube with argon leather hose.This mode is suitable only for the operation of short pipeline weld bond, and for the weld bond that pipeline is longer, argon waste is serious, is unfavorable for the saving of material cost.The second, argon filling near groove, block both sides, inner-walls of duct position to be welded with the water soluble paper in advance, every side, away from weld groove about 150mm, is then directly filled with argon to get rid of inner air tube with the argon-arc welding gun being further provided with in alloy pipe to be welded.This mode inconvenient operation, when welding, special messenger must coordinate argon filling, and sealing section weld seam is long, argon shield poor effect easily produces multiple weld defect and farther out distance construction time switch argon be inconvenient to the phenomenon that causes argon to waste.
All there is respective drawback in both the above argon filling mode, it is impossible to adapts to power station high alloy small-bore pipeline and install complicated construction situation when building.
Utility model content
The high alloy small-bore pipe welding argon-filling device that this utility model provides, simple in construction, operation is simple, may effectively save argon.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: high alloy small-bore pipe welding argon-filling device, include in being passed through the little copper pipe of argon, ignition tip, argon leather hose and the argon cross valve for being connected with argon pipeline to inside pipe wall, it is characterized in that ignition tip is run through in one end of described little copper pipe, it extend in argon leather hose, the other end has the ventilation end of flat flat shape, and one end of argon leather hose seals suit with ignition tip, and the other end is tightly connected with argon cross valve.
Further, described little copper pipe has the crotch-shaped that one end is semi arch of ventilation end.
Further, having the through hole for running through for little copper pipe in described ignition tip, described little copper pipe outer wall fits tightly with the inwall of through hole.
Further, ignition tip connects one end parcel insulated enclosure adhesive plaster of little copper pipe.
Further, described argon leather hose is enclosed with insulated enclosure adhesive plaster with the junction of ignition tip.
This utility model utilizes little copper pipe and the ventilation end of flat flat shape of minor diameter, makes little copper pipe can be easily inserted groove gap.Features of shape after utilizing little copper pipe to bend, can be the most reliable in stretching into tube groove gap be hooked in insides of pipes.The short circuit state utilizing argon cross valve can whip to regulate or switch argon cross valve to keep the supply of pipe interior argon in real time, easy to use again can effectively save argon, this utility model simple in construction, make simple, at installation scene, power station strong adaptability, be particularly well-suited to the needs of inwall argon filling when high alloy small-bore pipeline long pipe runs, complex environment welding procedure.
Accompanying drawing explanation
Fig. 1 is the front view of the high alloy small-bore pipe welding argon-filling device in detailed description of the invention.
Fig. 2 is the top view of the high alloy small-bore pipe welding argon-filling device in detailed description of the invention.
Detailed description of the invention
By drawings and Examples, this utility model will be further described below.
As shown in Figure 1 to Figure 2, high alloy small-bore pipe welding argon-filling device, include in being passed through the little copper pipe 1 of argon, ignition tip 2, argon leather hose 3 and the argon cross valve 4 for being connected with argon pipeline to inside pipe wall, ignition tip 2 is run through in one end of described little copper pipe 1, it extend in argon leather hose 3, the other end has the ventilation end 11 of flat flat shape, and one end of argon leather hose 3 seals suit with ignition tip 2, and the other end is tightly connected with argon cross valve 4.
Described little copper pipe 1 has the crotch-shaped that one end is semi arch of ventilation end 11.Having the through hole for running through for little copper pipe 1 in described ignition tip 2, described little copper pipe 1 outer wall fits tightly with the inwall of through hole.Ignition tip 2 connects one end parcel insulated enclosure adhesive plaster of little copper pipe 1.Described argon leather hose 3 is enclosed with insulated enclosure adhesive plaster with the junction of ignition tip 2.
During use, first argon cross valve 4 is connected with the pipeline being connected with argon, then the ventilation end 11 of little copper pipe 1 is extend in tube groove gap to be welded and reliable be hooked in insides of pipes.During bottom argon arc welding, by the hooking position of the semi arch crotch-shaped flexible transformation argon-filling device of little copper pipe 1, regulation or switch argon cross valve 4 are to keep the supply of pipe interior argon the most conveniently.
Above-described high alloy small-bore pipe welding argon-filling device, utilizes little copper pipe 1 and the ventilation end 11 of flat flat shape of minor diameter, makes little copper pipe 1 can be easily inserted groove gap.Features of shape after utilizing little copper pipe 1 to bend, can be the most reliable in stretching into tube groove gap be hooked in insides of pipes.The short circuit state utilizing argon cross valve 4 can whip in real time regulation or switch argon cross valve 4 with keep pipe interior argon supply, easy to use again can effectively save argon.Above-described high alloy small-bore pipe welding argon-filling device, simple in construction, make simple, at installation scene, power station strong adaptability, be particularly well-suited to the needs of inwall argon filling when high alloy small-bore pipeline long pipe runs, complex environment welding procedure.
Above in association with accompanying drawing, the technical scheme of this utility model embodiment is completely described; it should be noted that described embodiment is only a part of embodiment of this utility model; make based on the embodiment in this utility model; the every other embodiment that those of ordinary skill in the art are obtained on the premise of not making creative work, broadly falls into the scope of this utility model protection.
