Specific embodiment
In conjunction with referring to figs. 1 to 5, according to an embodiment of the invention, providing a kind of tube assembly, including the first pipe 1,
Two pipes 2, the first end of first pipe 1 are plugged in the axially extending bore of second pipe 2 and are welded to connect, first pipe 1
It is configured with gap between second pipe 2 and uniformly guarantees structure 3, the gap uniformly guarantees that structure 3 makes first pipe 1
First end is stablized on the position coaxial with second pipe 2.In the technical solution, since the gap uniformly guarantees structure
3 ensure that the concentricity of first pipe 1 and the second pipe 2, thus it is ensured that the periphery wall of first pipe 1 and described second
The uniformity in gap between the internal perisporium of pipe 2, when welding, uniform gap provides the space sufficiently flowed to solder
With channel, solder is enable to be uniformly distributed among gap, avoid in the prior art due to gap unevenly caused by solder
The generation of uneven bring burn-off phenomenon is gathered, while the exhaust that can be also conducive to welding process effectively prevents in welding process
The generation of stomata to guarantee welding quality, and then improves the mechanical performance and welding airtightness of tube assembly.
Uniformly guarantee a kind of specific embodiment of structure 3 as the gap, it is preferable that the gap uniformly guarantees to tie
Structure 3 includes multiple raised 31, multiple described raised 31 first pipe 1 being arranged in towards in the outer perimeter wall of second pipe 2,
And/or multiple described raised 31 be arranged in second pipe 2 towards on the inside peripheral wall of first pipe 1, more preferably
It is that described raised 31 are arranged in the lesser material of hardness, specifically, when the material of first pipe 1 is copper, the second pipe 2
When material is steel, then described raised 31 are arranged on first pipe 1, thus convenient raised 31 construction process.Into
One step, multiple described raised 31 along first pipe 1, and/or, the circumferencial direction uniform intervals setting of the second pipe 2, to make
Gap between first pipe 1 and second pipe 2 is of uniform size consistent in the circumferential.
Best, the gap uniformly guarantees that structure 3 further includes multiple grooves 32, multiple grooves 32 with it is multiple described
Protrusion 31 is correspondingly arranged, to guarantee that multiple described raised 31 can be respectively accommodated in corresponding groove 32, multiple grooves
32 are arranged in first pipe 1 towards in the outer perimeter wall of second pipe 2, and/or, multiple grooves 32 are arranged described
Second pipe 2 uniformly guarantees that structure 3 passes through the side of concave-convex grafting towards on the inside peripheral wall of the first pipe 1 namely gap
Formula guarantees the gap uniformity between first pipe 1 and the second pipe 2, while specific circumferential positioning action, prevents from welding
It circumferentially rotates to form uneven solder deposition between first pipe 1 and the second pipe 2 in the process.
Second pipe 2 end point corresponding with the first end has stop bit flange 21,21 direction of stop bit flange
The center axis of second pipe 2 extends, when first pipe 1 is inserted with second pipe 2, the first end of first pipe 1
In cartridge insertion direction by stop bit, at this point, it is axial by reliable location between first pipe 1 and second pipe 2, it prevents from welding
Axial float between first pipe 1 and the second pipe 2 described in journey forms uneven solder deposition.
It is especially described for the flowing smoothness further to solder in 2 welding process of first pipe 1 and the second pipe
When the end of the first pipe 1 and 21 location and installation of stop bit flange, in order to prevent because flowing not caused by closed at welded gaps
The generation of smooth phenomenon, it is preferable that the ventilation for penetrating through the interior outside of first pipe 1 is configured on the port side wall of the first end
Slot 11 or venthole, at this point, the solder of top can the gap between first pipe 1 and the second pipe 2 flow down, and simultaneously
Air in the welded gaps of signature is expelled, to further increase welding quality, certainly best, welding can be in inertia
It is carried out under the protection of gaseous environment, this can prevent inside pipe fitting from generating the foreign matters such as oxide layer.Preferably, the air channel 11 or
Venthole is configured with multiple, and multiple air channels 11 or venthole are arranged along the circumferential uniform intervals of the first end.
The material heat expansion rate of second pipe 2 inner wall of end opposite with the first end and the material of first pipe 1
Expect that coefficient of thermal expansion is identical.Based on this principle, it is preferable that second pipe 2 end opposite with the first end includes base
22 and the coating 23 in base's inner wall, the material heat expansion of the coating 23 material heat expansion rate and first pipe 1
Rate is identical, leads to welding inside weld seam so as to which thermal expansion (deformation) difference in welding process because of two kinds of materials is effectively reduced
The hidden danger that region cracks plays the role of pre- anti-leak.
In conclusion guaranteeing that the gap of fit clearance uniformly guarantees structure 3 due to being provided in the present invention, make described
The flowing of first pipe 1 and the second pipe 2 solder in the welding process is more uniform (being evenly distributed), and the high temperature for reducing solder continues
Time thereby reduces the crystal grain variation that inside pipe fitting is generated by high temperature, the mechanical strength of pipeline is effectively protected, when its application
When into compressor, the vibration resistance ability and compressor reliability of compressor circuit can be improved.
According to an embodiment of the invention, a kind of compressor is also provided, including air intake duct and/or exhaust pipe, the air intake duct
And/or exhaust pipe is made of above-mentioned tube assembly, due to using above-mentioned tube assembly, the vibration resistance ability of compressor circuit
It is obviously improved with compressor reliability.
Those skilled in the art will readily recognize that above-mentioned each advantageous manner can be free under the premise of not conflicting
Ground combination, superposition.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within principle.Above only
It is the preferred embodiment of the present invention, it is noted that for those skilled in the art, do not departing from this hair
Under the premise of bright technical principle, several improvements and modifications can also be made, these improvements and modifications also should be regarded as guarantor of the invention
Protect range.
