Abstract
The invention relates to a shielded welding dual-airbag pipeline plugging device. The shielded welding dual-airbag pipeline plugging device is composed of a first airbag, a second airbag, a connection pipe bundle, an exhaust safety valve, an air inflation expansion pipe and an exhaust pipe. The first airbag is connected with the second airbag through the connection pipe bundle, the exhaust safety valve is installed on the connection pipe bundle, and the air inflation expansion pipe and the exhaust pipe are connected with the first airbag. Compared with the prior art, the shielded welding dual-airbag pipeline plugging device is simple in structure, convenient to carry, easy to operate, less in use amount of inert gas and high in welding quality, and the safety coefficient is greatly increased.
Description
Technical field:
The invention belongs to metallurgical equipment mounting technique field, be a kind of protection weldering double bolloon duct closing type device specifically, connect construction for extraordinary pipeline inert gas-shielded arc welding.
Background technology:
In pipeline welding field; gas shielded arc welding welding procedure is a kind of conventional process; during welding, staff is in the outer operation of pipeline; not only to carry out inert gas shielding to outside pipeline; and inert gas (as argon gas etc.) will be filled with protect weld bond not oxidized in pipeline, thus ensure welding quality.
In the prior art, the measure carrying out inert gas shielding in pipeline has two kinds of conventional methods, and first method is: first by the pipeline of both sides, soldered place with closeouts shutoff such as cardboards, be then filled with inert gas.The shortcoming of this method is that plugging effect is poor, and inert gas easily leaks, and safety can not get ensureing, and it is more to consume inert gas, adds cost.Another kind method is: need operating personnel directly to enter near the inherent soldered pipe welding port of pipeline and arrange U-shaped cover, this kind of method danger coefficient is high.Operating personnel enters Pipe installing and takes out closeouts, if protect improper, inert gas will cause the injury of people, causes problems such as suffocating; If residual hazardous chemical in pipeline, also can bring very large risk to operation in addition.And when this kind of method uses in the unapproachable small-bore pipeline of personnel, very large operating difficulties can be brought.
Summary of the invention:
Object of the present invention is exactly the above-mentioned shortcoming existed for prior art, provides a kind of inert gas-shielded arc welding duct closing type device, makes easy construction, succinct; improve welding quality; reduce use and the waste of inert gas, improve safety coefficient, solve problems of the prior art.
The present invention for solving the problems of the technologies described above adopted technical scheme is:
A kind of protection weldering double bolloon duct closing type device, by the first air bag, the second air bag, connects tube bank, exhaust safety valve, inflation pipe and blast pipe composition; Connecting by connecting tube bank between first air bag and the second air bag, connecting in tube bank and exhaust safety valve is installed; Inflation pipe and blast pipe are connected with the first air bag respectively.
Described first air bag and/or the second air bag are connected with being connected to restrain by snap joint.
Described first air bag is connected with a standby pipes.
Luminous subsides is established in described connection tube bank.
Luminescence is sticked intrafascicular of tube connector.
Described first air bag and the second air bag arrange pull rope junction button respectively.
With the second air bag, two symmetrical pull rope junction buttons are set respectively at the first air bag away from the side being connected tube bank.
Described exhaust safety valve is connected with gaseous diffuser.
Compared with prior art, a kind of advantage of weldering double bolloon duct closing type device of protecting of the present invention is: structure is simple, and easy to carry, simple to operate, inert gas consumption is few, and welding quality is high, and safety coefficient improves greatly.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
In figure, the 1, first air bag, the 2, second air bag, 3, snap joint, 4, connect tube bank, 5, exhaust safety valve, 6, inflation pipe, 7, blast pipe, 8, standby pipes, 9, luminously to paste, 10, pull rope junction button, 11, gaseous diffuser.
Detailed description of the invention:
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the present invention will be described in detail.
As shown in Figure 1, a kind of protection weldering double bolloon duct closing type device, by the first air bag 1, second air bag 2, connect tube bank 4, exhaust safety valve 5, inflation pipe 6, blast pipe 7 forms; Connecting by connecting tube bank 4 between first air bag 1 and the second air bag 2, connecting in tube bank 4 and exhaust safety valve 5 is installed; Inflation pipe 6 and blast pipe 7 are connected with the first air bag 1 respectively.
Described first air bag 1 and/or the second air bag 2 by snap joint 3 be connected tube bank 4 and connect, can Fast Installation during use, convenient disassembly when not using, is easy to carry.
Described first air bag 1 is connected with a standby pipes 8, if desired fast aeration, can be inflated to the first air bag 1 by standby pipes 8 simultaneously.
Described connection tube bank 4 is established luminous subsides 9, luminous subsides 9 are located at and connect in the middle of tube bank 4, are convenient to the location of plugging device of the present invention in pipeline.
Described first air bag 1 and the second air bag 2 arrange pull rope junction button 10 respectively, with the second air bag 2, two symmetrical pull rope junction buttons 10 is set respectively at the first air bag 1 away from the side being connected tube bank 4.Connect pull rope junction button 10 by pull rope, be convenient in pipeline, carry out tractive to plugging device of the present invention.
Described exhaust safety valve 5 is connected with gaseous diffuser 11, can make inert gas rapid diffusion in pipeline.
During use, according to the choice of diameter first air bag of pipeline and the size of the second air bag.By pull rope, the first air bag 1 and the second air bag 2 are placed on both sides, place to be welded in pipeline needing welded pipe line side, by inflation pipe 6, inert gas is filled with the first air bag 1, inert gas enters the second air bag 2 by connecting tube bank 4, after reaching certain pressure, first air bag 1 and the second air bag 2 expansion plugging pipeline, forms a closed local space.Continue inflation, when pressure exceedes the setting pressure of exhaust safety valve 5, exhaust safety valve 5 is opened, by the gaseous diffuser 11 after exhaust safety valve 5 by inert gas Fast Filling to this space, form the environment that is full of inert gas, after reaching welding requirements, carry out weld job.After weld job, open blast pipe 7 and exit, treat that the first air bag 1 and the venting of the second air bag 2 terminate, take out the first air bag 1 and the second air bag 2, complete welding job.
Above-mentioned detailed description of the invention can not as limiting the scope of the invention, and for those skilled in the art, any alternate modification make embodiment of the present invention or conversion all drop in protection scope of the present invention.
The present invention does not describe part in detail, is the known technology of those skilled in the art of the present technique.
