Abstract
The present invention relates to the manufacture auxiliary device of electric heater unit, specifically a kind of Tube-sheet Welding argon protective device for tube body and tube sheet carry out argon gas protection on electrical heating babinet when argon tungsten-arc welding.The device includes the gas distribution tube of a ring seal, and the inner ring size of gas distribution tube is adapted with pipe plate upper electrothermal tube distribution to be welded；The venthole being distributed along tube body is provided on gas distribution tube madial wall；It is connected with total inlet pipe on gas distribution tube, and is connected to argon gas source by total inlet pipe.The present invention is good and simple in structure to the argon gas protecting effect of Tube-sheet Welding, manufacture and easy to use.
Description
Technical field
The present invention relates to the manufacture auxiliary device of electric heater unit, it is specifically a kind of on electrical heating babinet to tube body with
Tube sheet carried out when argon tungsten-arc welding the Tube-sheet Welding argon protective device of argon gas protection.
Background technology
Core component of the electrical heating core as electric heater is made of electric heating tube, tube sheet, control junction box, and electricity adds
Heat pipe is connect with tube sheet using welding manner, and connection structure has many advantages, such as that air-tightness is good, production cost is low, good reliability.
But since the electric heating tube outer diameter pipe size that more generally exchanges heat is smaller, generally Φ 12.5mm, and electrothermal tube stretches out on the outside of tube sheet
Length is longer, and more electrothermal tubes arrange also comparatively dense on tube sheet, thus when it is with Tube-sheet Welding, and welding difficulty is larger.Because often
When rule welding operation, the included argon protective device of argon-arc welding gun can not go deep into the welding position of root, make gas shield effect
Difference affects welding quality.
Invention content
The technical problem to be solved by the invention is to provide a kind of argon gas protecting effect to Tube-sheet Welding is good, and tie
Structure is simple, manufacture and Tube-sheet Welding argon protective device easy to use.
The Tube-sheet Welding argon protective device of the present invention includes the gas distribution tube of a ring seal, gas distribution tube
Inner ring size and pipe plate upper electrothermal tube distribution to be welded be adapted；It is provided on gas distribution tube madial wall and is distributed along tube body
Venthole；It is connected with total inlet pipe on gas distribution tube, and is connected to argon gas source by total inlet pipe.
Further, when the gas distribution tube horizontal setting, the outgassing direction of venthole has to below horizontal direction
15 ~ 25 ° of inclination angle.
Further, the gas distribution tube is placed in the cavity of a ring seal, and the madial wall of the cavity is filter
Web frame.
Further, the gas distribution tube and the cavity side of being loop configuration.
It is an advantage of the invention that：By the way that the annular gas distributor pipe detached with welding gun is arranged, tube sheet can be looped around
It around welding position, and is on comparable plan-position, is ensure that in welding process with the welding position of electrothermal tube root
Gas shield atmosphere；By the venthole and filter structure of annular spread, so that protective gas outlet is evenly distributed, further carry
High gas shield effect, protects welding quality.
Description of the drawings
Fig. 1 is the side, sectional structural schematic diagram of the embodiment of the present invention；
Fig. 2 is the top view cross section structural schematic diagram of the embodiment of the present invention.
Specific implementation mode
As shown, the Tube-sheet Welding argon protective device includes the gas distribution tube 1 of a ring seal, gas point
The inner ring size of stringing is adapted with pipe plate upper electrothermal tube distribution to be welded；It is provided with along tube body on gas distribution tube madial wall
The venthole 2 of distribution；It is connected with total inlet pipe 3 on gas distribution tube, and is connected to argon gas source by total inlet pipe, total inlet pipe
On be provided with shut-off valve 6.When 1 horizontal setting of gas distribution tube, the outgassing direction of venthole has to below horizontal direction 15 ~
25 ° of inclination angle.Gas distribution tube 1 is placed in the cavity 4 of a ring seal, and the madial wall of the cavity is strainer 5.Gas point
4 side's of being loop configuration of stringing 1 and cavity.
During its use, as shown in Figure 1,1 ring set of gas distribution tube is peripheral in electrothermal tube G root welds position,
In welding process, the plumb joint of welding gun Q stretches into electrothermal tube root from top and is welded, and protective gas is directly blowed to electrothermal tube
Root, so that welding position is completely disposed in protective atmosphere.
