AI Technical Summary

Technical Problem

In the prior art, the refrigerant flowing out of the compressor's exhaust port flows rapidly under high pressure, causing the connecting pipe connected to the compressor's exhaust port to be subjected to a large impact force, resulting in seal failure and refrigerant leakage.

Method used

By increasing the welding length of the first connecting pipe, the welding quality is improved, stress concentration is reduced, and the sealing reliability between the first connecting pipe and the main valve body is ensured. The connecting pipe is welded to the main valve body to enhance the welding strength. The position of the connecting pipe and the welding quality are controlled by the positioning structure and the transition section.

Benefits of technology

It effectively prevents refrigerant leakage, improves the reliability of the four-way valve assembly, compressor assembly and air conditioner, and reduces scrap rate and cost.
