Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation pipes, in particular to a thermal insulation pipe with adjustable thermal insulation layer thickness. Background Art

[0002] Insulated pipe is the abbreviation of insulated pipe. Insulated pipe is used for the transportation of liquid, gas and other media. It is used for thermal insulation of pipelines in petroleum, chemical industry, aerospace, military, central heating, central air conditioning, municipal and other fields. The insulation layer is wrapped around the outside of the pipe to keep the inner pipe warm.

[0003] The insulation layer is usually installed by tying or sleeve type. The tying type uses tying belts, tapes and other tying parts. After the insulation layer is wrapped around the outside of the inner pipe, it is tied and fixed. The sleeve type adds an outer pipe layer to the outside of the pipeline and installs the insulation layer between the outer pipe and the inner pipe.

[0004] The existing tied insulation layer is exposed outside the pipe and is easily worn and damaged by the environment. The sleeve insulation layer is installed between two pipe bodies, which is inconvenient to disassemble and assemble. It is also inconvenient to increase or decrease the thickness of the subsequent insulation layer. Therefore, it does not meet the existing needs. We have proposed an insulation pipe with adjustable insulation layer thickness. Utility Model Content

When adding or removing the insulation layer 2, it is convenient to disassemble and assemble, and the operation is convenient, which effectively improves the work efficiency of the operator;

[0032] Specifically, the outer tube body 3 adopts an assembly structure, which is composed of a first arc-shaped assembly tube 301 and a second arc-shaped assembly tube 302, so that it is detachable, and a long rod threaded piece 3012 and a threaded assembly hole 3021 are adopted to facilitate the user to assemble the upper and lower arc-shaped assembly tubes together.

[0034] The arc-shaped rubber pad 4 is constructed to fit the arc-shaped groove of the arc-shaped assembly tube. After the arc-shaped assembly tube is assembled on the insulation layer 2, the arc-shaped rubber pad 4 blocks the arc-shaped assembly tube from the insulation layer 2, preventing the insulation layer 2 from directly contacting the arc-shaped assembly tube and reducing its wear. At the same time, the arc-shaped rubber pad 4 can improve the shock absorption and reduce the vibration force. It is also elastic and can be adjusted according to the thickness of the insulation layer 2.
