Abstract
A kind of minor diameter titanium pipe weld seam protection cover, comprises that intrados is made as the fan-shaped cover body of opening, and described fan-shaped cover body is provided with end and stretches into the wireway in fan-shaped cover body, and wireway is provided with venthole; In fan-shaped cover body, be provided with the copper mesh between wireway and intrados.The utility model is simple in structure, when use, be stuck on titanium pipe, argon gas is soft by the venthole on wireway, outflow uniformly, argon gas is evenly distributed, smoothness, prevent that argon gas from forming eddy flow and bringing air in fan-shaped cover body, thereby the purity that ensures argon gas, can make He Jinfeng district, weld metal zone all reach first class of protection level, to ensure weldquality; Because protection is effective, protective gas is selected one-level argon gas, can greatly save welding cost.
Description
Technical field
The utility model belongs to welding protection device technique field, particularly a kind of minor diameter titanium pipe weld seam protection cover.
Background technology
Due to the development of industrial technology, titanium or titanium alloy, except war industry, has all obtained application widely in chemical industry field in recent years.Because titanium is a kind of active metal, under normal temperature, can generate fine and close oxide-film with oxygen, thereby keep high stability and corrosion resistance.At high temperature, titanium and oxygen, hydrogen, nitrogen reaction speed are very fast, and more than 300 DEG C, titanium can be inhaled hydrogen fast, more than 600 DEG C, and titanium oxygen uptake fast, more than 700 DEG C, titanium can be inhaled nitrogen fast, and the oxide-film that temperature generates more than 540 DEG C time is not fine and close.When titanium or titanium alloy welding, if contain more oxygen, hydrogen, nitrogen in weld seam, can make the plasticity in weld metal and high temperature Jin Feng district decline, particularly impact flexibility reduces greatly, causes embrittlement.
Therefore, several temperature ranges when how titanium material welding are effectively protected, and are technique important in titanium or titanium alloy application process.At present, while welding in titanium and titanium alloy factory, inert gas or vacuum protection for many Bian.In order to reach good welding grade, adopt high-purity argon gas (99,999% argon gas) protection, this argon gas selling at exorbitant prices, causes welding cost larger.Meanwhile, because the pipeline welding difficulty of minor diameter is larger, the protective cover volume that argon shield is used is in addition excessive, has further strengthened the difficulty of welding.
Utility model content
The purpose of this utility model is to provide a kind of minor diameter titanium pipe weld seam protection cover small and exquisite and easy to use simple in structure, light.
For achieving the above object, the technical solution of the utility model is: a kind of minor diameter titanium pipe weld seam protection cover, comprise that intrados is made as the fan-shaped cover body of opening, and described fan-shaped cover body is provided with end and stretches into the wireway in fan-shaped cover body, and wireway is provided with venthole; In fan-shaped cover body, be provided with the copper mesh between wireway and intrados.
Described wireway end and copper mesh are arc.
Between described wireway end and copper mesh, be filled with filler, filler is made up of sheet or strip stainless steel material.
In described fan-shaped cover body, be provided with axial arranged gag lever post, gag lever post is positioned at copper mesh intrados below.
The intrados two ends of described fan-shaped cover body are provided with surrounded slice.
Compared with prior art, advantage of the present utility model is:
1, the utility model comprises that intrados is made as the fan-shaped cover body of opening, and described fan-shaped cover body is provided with end and stretches into the wireway in fan-shaped cover body, and wireway is provided with venthole; In fan-shaped cover body, be provided with the copper mesh between wireway and intrados, it is simple in structure, when use, be stuck on titanium pipe, argon gas is soft by the venthole on wireway, outflow uniformly, argon gas is evenly distributed, smoothness, prevents that argon gas from forming eddy flow and bringing air in fan-shaped cover body, thereby ensures the purity of argon gas, can make He Jinfeng district, weld metal zone all reach first class of protection level, to ensure weldquality; Because protection is effective, protective gas is selected one-level argon gas (99,99% argon gas), can greatly save welding cost.
2, in fan-shaped cover body, be provided with the arc copper mesh between wireway and intrados, be convenient to by the heat on weld seam conduct, Bas Discharged in fan-shaped cover body goes, and ensures the purity of argon in fan-shaped cover body.
3, be provided with axial arranged surrounded slice at the two ends of the intrados of fan-shaped cover body, clamp titanium pipe when welding, use simple and direct.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Minor diameter titanium pipe weld seam protection cover as shown in Figure 1; it comprises the wireway 8 that fan-shaped cover body 1 and end are arc, and the intrados 6 of fan-shaped cover body 2 is made as opening, and fan-shaped cover body 1 inside is stretched in the end of wireway 8; wireway 8 is provided with venthole 2, and venthole 2 is towards the cambered surface of fan-shaped cover body 1.In fan-shaped cover body 1, be provided with the arc copper mesh 7 between wireway 8 and intrados 6, copper mesh 7 is multilayer, be convenient to by the heat on weld seam conduct, Bas Discharged in fan-shaped cover body 1 goes, and ensures the purity of argon in fan-shaped cover body 1.In fan-shaped cover body 1, be provided with axial arranged gag lever post 5, gag lever post 5 is positioned at the intrados below of copper mesh 7, for fixing copper mesh 7, prevents that copper mesh 7 and filler 4 from coming off.
Between the end of wireway 8 and copper mesh 7, be filled with filler 4, filler 4 is made up of sheet or strip stainless steel material.Two ends at the intrados 6 of fan-shaped cover body 1 are provided with axial arranged surrounded slice 3, clamp titanium pipe when welding, use simple and direct.
In the present embodiment, fan-shaped cover body 1 and surrounded slice 3 select red copper material to make, and quality softness is convenient to manual or mechanical blanking processing, while being convenient to weld, is out of shape according to weld shape; The material selection red copper of copper mesh 7, its thermal conductivity is good.
In the utility model, argon gas is soft by the venthole 2 on wireway 8, flow out uniformly, prevents that argon gas from bringing air at the interior formation eddy flow of fan-shaped cover body 1, thereby ensures purity and the weldquality of argon gas.
The utility model uses applicable to the all-position welding of φ 20mm～114mm titanium pipe, comprises the pipe fitting weldings such as straight length weld seam, straight tube and elbow, straight tube and threeway.
