Description

Technical Field

[0001] The present application relates to the field of wall-penetrating pipes, and in particular to a prefabricated wall-penetrating thermal insulation sleeve. Background Art

[0002] The external pipeline passing through the wall project is one of the basic projects often used in residential buildings. Insulation measures are often required for external pipelines passing through the wall. When the pipeline passes through the wall, in order to meet the thermal insulation needs, the best possible insulation measures are required in the pipeline section passing through the wall. In the past, the insulation method for pipelines passing through the wall was to first drill a hole in the wall, then pass the preset pipeline through the wall through the hole, and then fill the wall hole with insulation material outside the pipeline to achieve the effect of thermal insulation and fixation.

[0003] Publication number "CN216976255U" provides a new type of wall-through pipe with an anti-freeze cracking structure, including a No. 1 pipe body and a No. 2 pipe body. The outer surfaces of the No. 1 pipe body and the No. 2 pipe body are fixedly connected with a protective layer. The left part of the outer surface of the protective layer is fixedly sleeved with a shielding piece. The No. 1 pipe body and the No. 2 pipe body are both fixedly installed with an anti-freeze cracking device. The left end of the No. 1 pipe body is fixedly connected with a connecting pipe, and the outer surface of the connecting pipe is engraved with a plurality of external threads. The new type of wall-through pipe with an anti-freeze cracking structure described in the utility model can isolate and protect the No. 1 pipe body and the No. 2 pipe body through the No. 1 insulation layer, the No. 2 insulation layer and the vacuum layer in the protective layer to prevent the pipe bodies from being frostbitten by cold air. In addition, the anti-freeze cracking device can prevent the pipe bodies from freezing and cracking, and the shielding piece can prevent external animals such as mosquitoes, mice and birds from passing through the wall while quickly fixing the wall-through pipe, thereby preventing people's indoor life from being disturbed.

[0004] Although the existing wall-through pipes have certain thermal insulation functions during use, they still have problems with poor protection and thermal insulation performance. First, they do not have a good anti-rust function, which makes the surface of the wall-through pipes easily damaged. Second, they do not have good anti-aging performance, which also makes the wall-through pipes easily damaged. Third, the wear resistance is poor, which makes the surface of the pipe body easily worn. Fourth, the weather resistance is poor, which affects the protection performance of the wall-through pipes in many aspects and shortens the service life of the wall-through pipes.
