Technical Field

[0001] The utility model relates to the technical field of backwashing devices, in particular to a novel gas-liquid separator with a backwashing device. Background Art

[0002] As an important refrigeration equipment, the gas-liquid separator is arranged near the compressor suction port. It is mainly used to separate the gas and liquid (a small amount of impurities) in the evaporator outlet medium, so that the refrigerant sucked into the compressor is in gaseous state, avoiding liquid hammer in the compressor and further damage to the compressor. The part that needs to be solved is that there may be a small amount of residual matter in the gas-liquid separator after the separation is completed, causing blockage and pollution inside the gas-liquid separator. The solution is to install a backwash component on the outside of the gas-liquid separator. When the gas-liquid separator is blocked, start the backwash component to flush the gas-liquid separator, and discharge the sewage generated by the flushing out of the gas-liquid separator after the flushing is completed.

[0003] The above scheme and the existing technology cannot completely flush the backwash component in the gas-liquid separator. At this time, it is necessary to improve and optimize the backwash component so that the flushing agent can be completely filled inside the gas-liquid separator during flushing and discharged after the flushing is completed.

[0004] To this end, the utility model proposes a joint buffer structure and a flange pipe fitting for solving the above problems. Utility Model Content
