In, due to the limitation of condition, it tends to be difficult to operate；Second is from outside argon filling, and operating method is after carrying out air chamber, is used
A piece thinner pipe is inserted into inside from commissure, is then applicable paper around groove or other things clog, prevent argon gas
Overflow, but this method has many shortcomings, first, argon flow amount is too small, it is slow to be filled with speed, and argon filling effect is bad, second, as
Fruit is easily burnt using paper closure in welding process, causes weld defect.
How prior art present in defect is improved, and design is a kind of safer, the more preferable pipeline argon-filling device of effect, is
The technical problems to be solved in the utility model.
The content of the invention
The utility model is aiming at shortcoming present in prior art, there is provided a kind of large diameter pipeline argon-filling device, should
Device includes the body of one end closing, and body other end is provided with argon gas pipe joint, is provided with body and penetrates a side pipe
Multiple apertures of wall, when body is in straight condition, the aperture is distributed on the tube wall of the same side, is in annulus by body bending
During shape, the aperture is all located in annulus inner ring side wall.This argon-filling device, can be on groove, with pipeline internal water to be welded
Molten paper is collectively forming the air chamber of a good seal, and due to spreading all over aperture above, can quickly by argon gas be filled into air chamber it
It is interior, the too high generation dieseling of temperature caused by being closed at groove using paper is avoided, simultaneously because being filled from outside
Argon, it is easy to operate, it is not necessary to which that people enters tube interior；Simultaneously relative to traditional outside argon-filling method, the gas of air chamber is improved
Close property, argon filling speed.
The technical scheme that a kind of large diameter pipeline argon-filling device of the present utility model uses is：Include the pipe of one end closing
Body, body other end are provided with argon gas pipe joint, the multiple apertures for penetrating side tube wall are provided with body, at body
When straight condition, the aperture is distributed on the tube wall of the same side, by body bending in it is circular when, the aperture is all located at justifying
In ring inner ring side wall.
The hole diameter is less than pipe diameter.Small pitch of holes is unlimited, and number is unlimited, and columns is unlimited, can be according to actual feelings
Condition is processed, but is to ensure that gas smoothly overflows.
The sealing strip for protruding from tube wall is provided with tube wall.
Other pipe wall position surfaces outside tube wall side where the sealing strip is covered in aperture.
The sealing strip is located on the tube wall of aperture both sides, respectively on the diameter extended line of body.
The Breadth Maximum of the sealing strip and body is more than root of weld width, and is less than or equal to groove Breadth Maximum.
The sealing strip is refractory seals bar.
The body is Thermostable flexible hose.
The beneficial effects of the utility model are：This argon-filling device, can on groove, with the baffle plate of pipeline to be welded or
The internal water soluble paper is collectively forming the air chamber of a good seal, and due to spreading all over aperture above, quickly can be filled into argon gas
Within air chamber, the too high generation dieseling of temperature caused by being closed at groove using paper is avoided, simultaneously because from outside
Argon filling is carried out, it is easy to operate, it is not necessary to which that people enters tube interior；Simultaneously relative to traditional outside argon-filling method, gas is improved
Air-tightness, the argon filling speed of room.
The present apparatus is in use, can select length according to the diameter of pipeline to be welded, around one whole circle of weld seam, quickly form one
The air chamber of individual closing；And a whole circle aperture is provided with body, argon gas is to enter air inlet chamber from surrounding, substantially increases and improves argon filling speed
Degree.Using the present apparatus, the air chamber of a good seal can be quickly formed, and argon filling speed is fast, effect is good, and it is resistance to due to what is used
Elevated-temperature seal bar and body, avoid that spontaneous combustion occurs in welding process, improve security.When carrying out welding job, root
Body position is adjusted paragraph by paragraph according to the progress of welding job.
