Fig. 1 shows the structural representation of the pipeline assembly of prior art; And
Fig. 2 shows the structural representation of the embodiment one according to pipeline assembly of the present invention.
Wherein, above-mentioned accompanying drawing comprises the following drawings mark:
1, bassoon; 2, tubule; 3, positioning pit; 10, the first pipeline; 20, the second pipeline; 21, main paragraph; 22, welding coordinates section; 30, circular orientation structure.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figure 2, embodiment one pipeline assembly is air-conditioning duct assembly.This pipeline assembly comprises the first pipeline 10 and the second pipeline 20, second pipeline 20 is set on the first pipeline 10, the inwall of the second pipeline 20 has the circular orientation structure 30 coordinated with the first pipeline 10.In the present embodiment, circular orientation structure 30 is inwardly concaved by the sidewall of the second pipeline 20 and is formed.By being welded to connect between first pipeline 10 and the second pipeline 20.
The pipeline assembly of application the present embodiment, inwardly concaved by the sidewall of the second pipeline 20 and form circular orientation structure 30, this circular orientation structure 30 coordinates to realize the location to the first pipeline 10 with the first pipeline 10.Above-mentioned circular orientation structure 30 coordinates area larger with the first pipeline 10, and assembling is more prone to, and positioning precision is higher, thus makes not easily to be partially welded when welding between the first pipeline 10 and the second pipeline 20, ensure that product quality.
In the prior art, when locating and machining concave point (or salient point), there is the risk of beating tube wall, pipe fitting can be caused to leak once tube wall beats.In addition, locating and machining concave point (or salient point) needs special equipment and special operating personnel, therefore, it is separate that processing concave point (or salient point) operation operates with processing tube body, need to carry out transhipment pipe fitting, above-mentioned situation causes the increase of production cost, the waste of human resources.
As shown in Figure 2, in the pipeline assembly of embodiment one, the second pipeline 20 comprises main paragraph 21 and welding coordinates section 22.Circular orientation structure 30 coordinates between section 22 at main paragraph 21 with welding, and welding coordinates section 22 to be set on the first pipeline 10 and and by being welded to connect between the first pipeline 10.The internal diameter of main paragraph 21 is greater than the internal diameter of welding cooperation section 22.The external diameter of main paragraph 21 is greater than the external diameter of welding cooperation section 22.In the present embodiment, circular orientation structure 30 can be formed by carrying out deformation operation to the tube body of the second pipeline 20 on the equipment of processing tube body.Particularly, first on the main paragraph 21 of the second pipeline 20, form one by necking down process and enclose scrobicular ring, namely form circular orientation structure 30, then form welding cooperation section 22 by enlarging technique in circular orientation structure 30.Above-mentioned circular orientation structure 30 coordinates between section 22 at main paragraph 21 and welding.First pipeline 10 is inserted in the second pipeline 20, and circular orientation structure 30 coordinates with the first pipeline 10 and positions, and positioning precision is higher.Simultaneously, the risk of beating saturating tube wall and causing leaking can not be there is in the processing of above-mentioned circular orientation structure 30, significantly improve product quality, and the processing of the processing of circular orientation structure 30 and processing tube body uses same equipment, can complete without the need to replacement operation equipment, more convenient to operate, production efficiency is higher, reduce pipe fitting transhipment and operating personnel's quantity (reducing the personnel of processing sags and crests), play the effect of significantly cutting payroll to improve efficiency.
In the pipeline assembly of embodiment one, circular orientation structure 30 has the first location fit face, and the first location fit face is arranged along the radial direction of the second pipeline 20, matches with the end face of the first pipeline 10 in the first location fit face.When circular orientation structure 30 positions the first pipeline 10, match with the end face of the first pipeline 10 in above-mentioned first location fit face, namely the end face of the first pipeline 10 is held in the first location fit face, thus realize the effect to the first pipeline 10 location.After this, then to fixing by being welded to connect between the first pipeline 10 and the second pipeline 20.Certainly, the fit form of circular orientation structure 30 and the first pipeline 10 is not limited thereto, and in other embodiments, annular recess can coordinate with other positions of the first pipeline, can to the positioning instant of the first pipeline as long as can realize.
The pipeline assembly (not shown) of embodiment two and the main distinction of embodiment one are, circular orientation structure has the second location fit face, second location fit face is arranged along the axial direction of the second pipeline, matches with the first pipeline circumferential exterior surface in the second location fit face.When circular orientation structure positions the first pipeline, above-mentioned second location fit face matches with the circumferential exterior surface of the first pipeline circular orientation structure and the first pipeline are clamped, thus realizes the effect to the first pipeline location.
The pipeline assembly (not shown) of embodiment three and the main distinction of embodiment one are, circular orientation structure comprises the annular protrusion in the circumferential inner surface being arranged on the second pipeline.When assembling first pipeline and the second pipeline, above-mentioned annular protrusion positions the first pipeline, end face or the circumferential exterior surface of this annular protrusion and the first pipeline match, coordinate area larger, assembling is more prone to, positioning precision is higher, thus makes not easily to be partially welded when welding between the first pipeline and the second pipeline, ensure that product quality.
Present invention also provides a kind of air-conditioner, the embodiment according to the air-conditioner of the application comprises pipeline assembly, and pipeline assembly is above-mentioned pipeline assembly.The pipeline assembly assembling of above-mentioned air-conditioner is more prone to, good product quality.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
