description The utility model provides a pressure limiting valve and a sealing structure thereof. The pressure limiting valve comprises a pressure limiting valve assembly, a connecting assembly, a sealing assembly, a pressure relief part and an air guide element. The connecting assembly is used for being connected with the breathing pipeline and the pipe wall of the mounting channel, the connecting assembly is provided with an air flow channel, and the air flow channel can convey air in the breathing pipeline into the pressure limiting valve assembly for pressure relief; the sealing assembly is used for sealing the joint of the mounting channel and the connecting assembly and the joint of the connecting assembly and the breathing pipeline; one end of the pressure relief piece blocks or opens an outlet of the airflow channel, and when the pressure relief piece blocks the airflow channel, the pressure of the pressure relief piece on the connecting assembly is controlled according to the pressure applied to the pressure rel
