Description
Technical field:
This utility model belongs to metallurgical equipment mounting technique field, specifically a kind of protection weldering double bolloon duct closing type device, connects 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 will to carrying out inert gas shielding outside pipeline; and in pipeline, to be filled with noble gas (such as argon) protect weld bond not oxidized, thus ensureing welding quality。
In the prior art, the measure carrying out inert gas shielding in pipeline has method two kinds conventional, and first method is: first by blocking by closeouts such as cardboards in the pipeline of both sides, soldered place, be then charged with noble gas。The shortcoming of this method is that plugging effect is poor, and noble gas easily leaks, and safety can not get ensureing, and it is more to consume noble gas, adds cost。Another kind of method is: the pipe welding port needing operating personnel to enter directly into pipeline inherence soldered is arranged around U-shaped cover, and this kind of method danger coefficient is high。Operating personnel enters Pipe installing and takes out closeouts, if protecting improper, noble gas will result in the injury of people, causes problems such as suffocating；If additionally residual hazardous chemical in pipeline, also brings along very big risk to operation。And when this kind of method uses in the unapproachable small-bore pipeline of personnel, very big operating difficulties can be brought。
Utility model content:
The purpose of this utility model is aiming at the disadvantages mentioned above that prior art exists, it is provided that 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 noble gas, improve safety coefficient, solve problems of the prior art。
This utility model be the technical scheme is that by the above-mentioned technical problem of solution
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 exhaustor composition；By connecting tube bank connection between first air bag and the second air bag, connect and tube bank is provided with exhaust safety valve；Inflation pipe and exhaustor are connected with the first air bag respectively。
Described first air bag and/or the second air bag are connected with being connected tube bank by snap joint。
Described first air bag and a standby pipes connect。
Described connection sets decal in tube bank。
Decal is located in the middle of connection tube bank。
Described first air bag and the second air bag are respectively provided with pull rope junction button。
It is respectively provided with two pull rope junction buttons of symmetry away from the side connecting tube bank at the first air bag and the second air bag。
Described exhaust safety valve is connected with gaseous diffuser。
Compared with prior art, this utility model is a kind of protects the advantage of weldering double bolloon duct closing type device to be: simple in construction, easy to carry, simple to operate, noble gas consumption is few, and welding quality is high, and safety coefficient is greatly improved。
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model。
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, exhaustor, 8, standby pipes, 9, decal, 10, pull rope junction button, 11, gaseous diffuser。
Detailed description of the invention:
For knowing the technical characterstic that this programme is described, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated。
As it is shown in figure 1, a kind of protection weldering double bolloon duct closing type device, by first air bag the 1, second air bag 2, connecting tube bank 4, exhaust safety valve 5, inflation pipe 6, exhaustor 7 forms；By connecting tube bank 4 connection between first air bag 1 and the second air bag 2, connect and tube bank 4 is provided with exhaust safety valve 5；Inflation pipe 6 and exhaustor 7 are connected with the first air bag 1 respectively。
Described first air bag 1 and/or the second air bag 2 are restrained 4 by snap joint 3 connect with being connected, during use can Fast Installation, convenient disassembly when not using, it is simple to carry。
Described first air bag 1 and a standby pipes 8 connect, if desired fast aeration, can be inflated to the first air bag 1 by standby pipes 8 simultaneously。
Described connection sets decal 9 in tube bank 4, and decal 9 is located in the middle of connection tube bank 4, it is simple to this utility model plugging device location in pipeline。
Described first air bag 1 and the second air bag 2 are respectively provided with pull rope junction button 10, are respectively provided with two pull rope junction buttons 10 of symmetry at the first air bag 1 and the second air bag 2 away from the side connecting tube bank 4。Pull rope junction button 10 is connected, it is simple to this utility model plugging device is carried out tractive in pipeline by pull rope。
Described exhaust safety valve 5 is connected with gaseous diffuser 11, and noble gas can be made quickly to spread in pipeline。
Size during use, according to the choice of diameter first air bag of pipeline and the second air bag。By pull rope, the first air bag 1 and the second air bag 2 are placed in pipeline both sides, place to be welded needing welded pipe line side, by inflation pipe 6, noble gas is filled with the first air bag 1, noble gas is by connecting tube bank 4 entrance the second air bag 2, after reaching certain pressure, first air bag 1 and the second air bag 2 expansion plugging pipeline, forms one and closes local space。Continuing 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 noble gas Fast Filling to this space, form the environment of a full noble gas, after reaching welding requirements, carry out weld job。After weld job, open exhaustor 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。
