Pipeline joint assembly of heat pump system

The utility model discloses a pipeline joint assembly of a heat pump system in the technical field of heat pump pipeline connection, which comprises a pipeline A and a pipeline B. The inner wall of one end of the pipeline A is provided with a groove A. The pipeline joint assembly is reasonable in structure. The pipeline A and the pipeline B are connected and communicated through the connector assembly, after the connector assembly is installed, the two sets of annular fixing heads are clamped into the outer walls of the connecting rings at one ends of the pipeline A and the pipeline B, locking and fixing are conducted in cooperation with the screws and the locking nuts, and therefore the pipeline A and the pipeline B are connected and fixed. And meanwhile, the joint assembly has a good sealing effect, so that after the pipeline A and the pipeline B are communicated, the situation that conveyed gas or liquid leaks out through a gap generated after connection is avoided, and the sealing performance and the conv
