Heat insulation structure of heat distribution pipeline

The utility model relates to the technical field of heat distribution pipelines, in particular to a heat distribution pipeline heat preservation structure which comprises a pipeline body, first heat preservation layers, supporting layers A, second heat preservation layers and supporting layers B. The first heat preservation layers are arranged on the outer surface of the pipeline body in an annular array mode, and the supporting layers A are fixedly connected to the outer surfaces of the first heat preservation layers correspondingly. The outer surface of the supporting layer A is connected with a second heat preservation layer in a matched mode, the outer surface of the second heat preservation layer is fixedly connected with a supporting layer B, connecting seams formed by the first heat preservation layer and the second heat preservation layer are distributed in a staggered mode, and the first heat preservation layer and the second heat preservation layer are made of the same material. And grooves and conn
