Heat exchange communication device of heat supply pipe network

The utility model relates to the technical field of heat supply pipe networks, in particular to a heat supply pipe network heat exchange communication device which comprises a first pipeline and a second pipeline. Compared with the prior art, the connecting structure has the advantages that the first limiting ring is arranged, the first limiting ring is in threaded connection with the first pipeline, meanwhile, the section of the first limiting ring is in an L shape, stable supporting is formed, the first pressing end cover, the connecting shell and the second pressing end cover are arranged, meanwhile, the first sealing ring is arranged between the first protruding part and the first limiting ring, and therefore stable supporting is achieved. A second sealing ring is arranged between the second pressing end cover and the second convex part, so that the first sealing ring and the second sealing ring can be respectively pressed by screwing the first pressing end cover and the second pressing end cover, the sea
