TECHNICAL FIELD
[0001] The utility model relates to the field of liquid accumulator, in particular to the liquid accumulator air pipe joint. BACKGROUND
[0002] The liquid accumulator is an important component of the compressor, which plays the role of storing refrigerant, gas-liquid separation, filtering, sound attenuation and buffering. The liquid accumulator is installed in the air conditioner evaporator and the compressor suction pipe part, and it is a protective component that prevents liquid refrigerant from flowing into the compressor to cause liquid hammer. Specifically, during the operation of the air conditioning system, it cannot be guaranteed that all the refrigerant is completely vaporized. That is, the liquid refrigerant from the evaporator will enter the liquid accumulator, and the liquid refrigerant that has not been vaporized will directly fall to the bottom of the liquid accumulator cylinder because it is heavier than gas. The vaporized refrigerant enters the compressor through the outlet of the liquid accumulator, thereby preventing the compressor from sucking liquid refrigerant to cause liquid hammer.
[0003] However, the input end of the liquid accumulator needs to be connected with the external air pipe through a joint. The conventional liquid accumulator air pipe joint, such as the patent with the application number CN201921957249.6 and the invention name of a refrigeration liquid accumulator air pipe joint structure, has poor sealing effect and is not convenient to disassemble and connect.
