Document Type and Number:
WIPO Patent Application WO/2022/218023
Kind Code:
A1
Abstract:
Provided are a joint assembly, a four-way valve assembly and an air conditioner system. The joint assembly comprises a first pipe fitting (10), a second pipe fitting (20), a first connecting sleeve (30), which is connected to one end of the first pipe fitting (10), and a second connecting sleeve (40), which is connected to one end of the second pipe fitting (20), wherein the first connecting sleeve (30) is connected to the second connecting sleeve (40); the first connecting sleeve (30) is a first straight pipe, and the second connecting sleeve (40) is a second straight pipe that is nested with the first straight pipe; or, the first connecting sleeve (30) is a first reducer pipe, and the second connecting sleeve (40) is a second reducer pipe that is nested with the first reducer pipe. By means of the technical solution, the problem of welding between a stainless steel pipe set and a copper pipe set being limited due to the size of a welding furnace being limited is effectively solved.
