NOVELTY - The utility model model claims a centrifugal air compressor sealing structure, comprising a connecting sealing pipe, the left and right ends of the connecting sealing pipe are fixedly installed with a connecting pipe close to the middle; the connecting pipe is provided with two, and one side of the two connecting pipe opposite to the periphery is fixedly installed with a connecting disc, the connecting plate is movably provided with a connecting bolt, and one side of the two connecting pipe opposite to the middle position are fixedly installed with a graphene ring. The utility model model can install the sealing structure between the air transmission pipe of the air compressor during the connection period, can be connected with the gas transmission pipe through the connection disc and the connection bolt, at the same time, the graphene ring can seal the joint, avoiding the gap, during the installation period, can be fixed by rod the gas transmission pipe, so as to improve the stability of the sealing structure and the air compressor avoid the vibration caused by the dislocation of the connection.
