Description
Technical field
The utility model belongs to connecting pipe technical field, is related to a kind of red copper pipe fitting, and more particularly to a kind of red copper is led directly to
Pipe fitting.
Background technology
Copper tube is also known as copper pipe, is non-ferrous metal one kind, is the seamless pipe of compacting and drawing, copper tube total amount is lighter, leads
Hot good, low temperature intensity is high, is usually used in manufacturing heat transmission equipment, is also used for assembling cryogenic pipe in oxygen generating plant.
It is most common one kind in copper tube that red copper, which leads directly to pipe fitting, implements the machinery of copper tube using processing compression type pipe fitting
Connection, and be that red copper leads directly to pipe fitting and connects one of common construction method, the construction method that it is connected with non-processing compression type it
Difference, when being before constructing copper tube pipe end must be formed processing, i.e. red copper pipe construction, its pipe end is corrected by cutting
Afterwards, it is also necessary to which special forming tool, cup-shaped or taper are flared by tube end maching, and cupulate or tapered form, size need
It is unified and standard.Because the connection of processing compression type copper pipe fitting, directly corresponding to copper pipe fitting combined by the pipe end of cupulate or taper
Face is sealed to ensure pipe joint densification, so needing to ensure that copper tube will not rotate and influence to seal during crimping
Property, in addition soldering is also required to copper tube positioning, not so can influence welding effect, but existing copper tube is bad in the presence of positioning
Problem, and it is vulnerable to stress corrosion at the extension of copper tube pipe shaft, it is easily cracked, influence service life.
The content of the invention
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, there is provided a kind of service life length,
Orientable red copper leads directly to pipe fitting.
The purpose of this utility model can be realized by following technical proposal：A kind of red copper leads directly to pipe fitting, including in straight tube
The tube body of shape, one end of the tube body is linkage section one, and the other end of tube body is more than the linkage section two of linkage section one for diameter,
Between the linkage section one and linkage section two by conical surface section in succession, it is characterised in that the conical surface section is coated with glue
Set, one end of the gum cover is extended and covered section linkage section one, and the other end of the gum cover extends and covered section connects
Section two is connect, the linkage section one and/or linkage section two are equipped with location structure.
Led directly in a kind of above-mentioned red copper in pipe fitting, the location structure includes some weeks that two outer wall of linkage section has
To equally distributed protrusion.By raised setting, facilitate the positioning of tube body so that easy to connect and connection precision is high.
Led directly in a kind of above-mentioned red copper in pipe fitting, the raised quantity is distributed in linkage section two for four pieces and protrusion
In the middle part of outer wall.So structural strength is good and easy to arrangement.
Led directly in a kind of above-mentioned red copper in pipe fitting, it is described it is raised towards the side of conical surface section be inclined plane, it is described
Inclined plane is 30 ° in the angle of itself and tube body axis on radial section.The setting of inclined plane facilitates slipping into for compaction tool, convenient
Positioning action.
As another situation, led directly in a kind of above-mentioned red copper in pipe fitting, the location structure includes linkage section two
The circle bulge loop annular in shape that outer wall has.The setting of bulge loop facilitates tube body to position.
Led directly in a kind of above-mentioned red copper in pipe fitting, the linkage section one and conical surface section, conical surface section and linkage section two it
Between be round-corner transition.The setting of fillet reduces the stress concentration of junction everywhere, and also so that tube body internal resistance is small, medium leads to
The property crossed is good.
Compared with prior art, this red copper lead directly to pipe fitting resistance it is small, passability is good, effectively weakens stress concentration, and
Gum cover is good to the encapsulation of conical surface section, and conical surface section stress corrosion resistant ability is good, even if conical surface section stress corrodes cracked, glue
Set can also prevent from revealing, and extend service life, and in addition this red copper leads directly to pipe fitting and can position, convenient connection installation and connection precision
It is high.
