Problems solved by technology

[0004] The purpose of the present invention is to propose a pipeline welding structure and an air conditioner to solve the problem that the relative rotation of the welding pipeline in the prior art tends to cause a large deviation between the pipeline structure after welding and the design structure, thereby affecting the later stage. Mounting and stress distribution issues

Embodiment Construction

[0023] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the present invention.

[0024] At present, the welding of the four-way valve and the pipeline of the four-way valve often has the problem of pipeline rotation, which leads to a large deviation between the pipeline structure after welding and the design structure, which affects the later installation and stress distribution.

[0025] The general way to solve this problem is to clamp and manually modify the pipeline structure. Clamping will reduce work efficiency. Manually correcting the pipeline structure not only reduces work efficiency but also makes it diffic...

Abstract

The invention discloses a pipeline welding structure and an air conditioner. The pipeline welding structure comprises a first round pipe (1) and a second round pipe (2), the welding end of the first round pipe (1) is sleeved outside the welding end of the second round pipe (2), and the first round pipe (2) The welded end interface of the pipe (1) is a non-circular hole, and the cross-sectional shape of the welded end interface of the second round pipe (2) matches the cross-sectional shape of the welded end interface of the first round pipe (1). According to the pipeline welding structure of the present invention, it is possible to solve the problem in the prior art that the welded pipeline is prone to relative rotation, resulting in a large deviation between the welded pipeline structure and the designed structure, thereby affecting the later installation and stress distribution.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a pipeline welding structure and an air conditioner. Background technique [0002] In the Chinese utility model patent application with the application number of 201120267891.9, a four-way valve connection mechanism of an outdoor unit is disclosed. The projected position between the axial centerlines of the valves shall be parallel, vertical or at an angle of 45° to specify the pipeline assembly angle, thereby improving the accuracy and ease of operation of the four-way valve assembly process and effectively avoiding pipeline stress distribution Changes and refrigerant leaks. For the four-way valve installed in the refrigerant pipeline, the initial section of the exhaust pipe is perpendicular to the axial centerline of the four-way valve. The bent section of the suction pipe is parallel to or perpendicular to the axial centerline of the four-way valve, or forms an included ang...
