Heat preservation and energy saving device for pipeline of primary network heat exchange station

The utility model relates to the technical field of pipeline heat preservation, in particular to a primary net heat exchange station pipeline heat preservation energy-saving device which comprises a pipeline body, an inner protection pipe is fixedly connected to the outer surface of the pipeline body in a penetrating mode, an outer protection pipe is fixedly connected to the outer portion of the inner protection pipe in a penetrating mode, and a wrapping shell is movably connected to the outer surface of the outer protection pipe. According to the heat preservation and energy saving device for the primary net heat exchange station pipeline, the pipeline body is sleeved with the inner protection pipe, then the inner protection pipe is sleeved with the outer protection pipe, due to the fact that the outer surface of the inner protection pipe protrudes outwards, the pipeline body is protected under the matching effect of the inner protection pipe and the outer protection pipe, the pipeline body is prevented from
