Problems solved by technology
[0002] The original direct-buried sleeve compensator adopts the same fully enclosed insulation method as the straight pipe. When the compensator is running, the insulation space is compressed, and the polyurethane foam will expand and damage the outer protection pipe, resulting in the loss of function of the insulation structure.

The invention discloses a heat insulation structure of a hot water sleeve compensator; a movable end of the compensator is externally sheathed with an external protecting tube of the movable end; one end of the external protecting tube of the movable end is connected with a connecting sleeve, and the other end of the external protecting tube of the movable end is fixed on a sliding support frame; a fixed end of the compensator is externally sheathed with a heat insulation layer which is externally sheathed with an external protecting tube of the fixed end; one end of the external protecting tube of the fixed end is connected with the connecting sleeve; and the external protecting tube of the movable end and the external protecting tube of the fixed end are respectively sheathed with an outer sleeve. According to the heat insulation structure of the hot water sleeve compensator, a connecting pipe is not needed by the heat insulation structure, and variable diameter structures are not adopted by the external protecting tubes, so that the processing technology is simple, and the cost is low; moving structures of the external protecting tubes are adopted, so that the heat insulation layer and the external protecting tubes are guaranteed not to be damaged by the compensator in the stretching process; and a movable end of the external protecting tube is not provided with a sealing element, so that underground water can easily enter into the compensator, and the anticorrosion treatment is carried out on the metal surface of the compensator by spraying polyurea or zinc-rich paint.
Description
technical field [0001] The invention relates to a thermal insulation structure of a hot water sleeve compensator. Background technique [0002] The original direct-buried sleeve compensator uses the same fully-enclosed insulation method as the straight pipe for insulation. When the compensator is running, the insulation space is compressed, and the polyurethane foam will expand and damage the outer protection pipe, resulting in the loss of function of the insulation structure. Contents of the invention [0003] The purpose of the present invention is to provide a thermal insulation structure of a hot water sleeve compensator. [0004] The technical solution adopted by the present invention to achieve the above purpose is: a thermal insulation structure of a hot water sleeve compensator. The other end is fixed on the sliding support frame, the fixed end tube of the compensator is covered with an insulation layer, the insulation layer is covered with a fixed end outer prote...
