Abstract
The utility model relates to a protective gas sealing device in a pipeline welding pipe, which is characterized in that two annular air bags are respectively arranged on two brackets; the two brackets are connected together through a connecting device; and the connecting device is communicated with an argon gas supply device. The protective gas sealing device has the advantages of simple structure and convenient use, the pipeline welding position required to be welded can be basically sealed only through inflating the annular air bags, so as to greatly reduce the consumption of argon gas, reduce the welding cost, and facilitate the environment protection; and meanwhile, the concentration of the argon gas in a pipeline is more easier to be controlled within the proper scope, so that the back surface of the pipeline is protected fully, and the welding quality is better ensured.
Description
Technical field:
The utility model relates to a kind of mechanical device, and the sealing device of gas in particularly a kind of closed conduct when being used for the special steel material welding, seals, reduces the device of its leakage to the protective gas that charges in the pipeline.
Background technology:
At present, argon arc welding is widely used in the welding of some special rolling-mill sections, and along with the requirement of welding quality improves constantly, argon shield need be carried out in some steel welding back side when adopting argon arc welding, as the steel pipe of steel grades such as austenitic stainless steel.Usually the back side applying argon gas protection of pipeline argon arc welding welding is all adopted at direct applying argon gas in pipe after the pipe ends shutoff, thereby reaches the purpose of welding back side argon shield.Because the length that the size of pipe diameter and pipe group are right is different, brings a lot of factors that can't determine for the aeration quantity of applying argon gas in the pipe, the aeration quantity that the pipeline of particularly large diameter pipeline and long distance (as the fixing mouth of pipe) is managed interior applying argon gas is very big.These steel pipes must ceaselessly charge into argon gas in pipe when welding, therefore, during the pipeline welding of this class material, the argon gas use amount is very big, and welding cost is strengthened, and simultaneously, a large amount of argon gas are unfavorable for the protection of environment directly to airborne release.
Summary of the invention
The purpose of this utility model provides a kind of aeration quantity that applying argon gas is protected and reaches expectation and effectively control, thereby reduces the use amount reduction welding cost of argon gas, the interior protective gas sealing device of pipeline welding pipe of minimizing toxic emission significantly.
The realization the technical solution of the utility model is; protective gas sealing device in a kind of pipeline welding pipe is characterized in that two annular air-pockets are separately positioned on two carriages; two carriages link together by jockey, and described jockey is provided with the argon gas feeder.
The utility model has the advantages that, simple in structure, easy to use, only need annular air-pocket is inflated, just pipeline welding place of needs welding can be sealed substantially, a spot ofly leak away, rather than prior art is expedite is communicated with airborne release by pipeline by steam vent thereby the argon gas that charges into is had only.The use amount of argon gas is declined to a great extent, and has reduced welding cost, also more helps environmental protection, and argon concentration is more easy to control in suitable scope in the pipeline simultaneously, makes the protection at the pipeline back side more abundant, guarantees welding quality better.
