Problems solved by technology

[0002] The pipeline connection of the refrigeration system, under normal circumstances, low and medium pressure systems can use non-metallic sealing rings made of materials such as rubber, polytetrafluoroethylene, asbestos, etc. Under certain conditions, it is difficult for non-metallic sealing rings to ensure a stable and reliable sealing effect
Therefore, there are gaskets made of metal materials at present, but the elastic extrusion force of general metal gaskets is insufficient, the amount of elastic deformation is small, and there is almost no self-sealing effect

Abstract

The invention discloses a pipeline switching device and an automobile air conditioning system using the same. The pipeline switching device comprises a fastener, an annular part, a first connecting block and a second connecting block, wherein the first connecting block comprises a first channel and an abutting part; the second connecting block comprises a second channel and a containing part; andthe annular part is arranged on the containing part and abuts against the abutting part and the bottom wall of the containing part, so that the sealing connection between the first channel and the second channel is realized.

Description

technical field [0001] The present application relates to the technical field of refrigeration, in particular to a refrigeration system pipeline adapter device and an automobile air-conditioning system using the pipeline adapter device. Background technique [0002] The pipeline connection of the refrigeration system, under normal circumstances, low and medium pressure systems can use non-metallic sealing rings made of materials such as rubber, polytetrafluoroethylene, asbestos, etc. Under certain conditions, it is difficult for non-metallic sealing rings to ensure a stable and reliable sealing effect. Therefore, there are gaskets made of metal materials at present, but the general metal gaskets have insufficient elastic extrusion force, small elastic deformation, and almost no self-sealing effect. Contents of the invention [0003] The purpose of the present invention is to provide a pipeline transfer device with self-sealing effect. [0004] A pipeline transition devic...
