Title:
VALVE AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2021/143285
Kind Code:
A1
Abstract:
A valve and an air conditioner, which relate to the technical field of air conditioners. In the valve, a valve seat sleeve (2) is fixed within a cavity of a connecting end of a first connecting portion (1), and a telescopic sealing assembly (3) is installed within the valve seat sleeve (2). Meanwhile, a first sealing boss (4) that cooperates with the sealing assembly (3) to form a seal is provided on an inner wall of the cavity of the valve seat sleeve (2); when connected to a connecting pipe and a refrigerant is introduced, the sealing assembly (3) will be compressed by force so as to be separated and connected to the first sealing boss (4); and before the refrigerant is introduced, the connecting end of the first connecting portion (1) is in a sealed state, thereby having a self-sealing and pressure-maintaining function. During installation, merely directly connecting to the connecting pipe is required, avoiding vacuumization, achieving convenient and quick installation, thus not requiring a high level of expertise for carrying out installation and reducing the complexity of the device, and reducing installation time and installation costs; meanwhile, the connecting operation process will not lead to refrigerant leakage, avoiding environmental pollution, preventing air from entering an air conditioning system, and avoiding affecting machine performance.
