Problems solved by technology

[0003] There are also double-layer heat-insulating pipes on the market now, and the insulation gas is filled in the middle of the double-layer heat-insulating pipes to achieve enhanced heat insulation effect. , will cause the double-layer heat insulation pipe to appear sunken in some areas, reducing the insulation effect, and it is extremely inconvenient for personnel to repair it. It is necessary to dismantle the pipe for replacement and repair again, and the construction period is longer. Therefore, we propose a double-layer insulation pipe. layer insulation pipe

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] see Figure 1-7 , a double-layer heat-insulated pipe in the illustration, including an inner pipe 1 and an outer pipe 2, both of which are made of materials with high thermal conductivity and high specific heat capacity, and the outer pipe 2 is sleeved on the inner pipe 1 On the outside, between the outer tube 2 and the inner tube 1 are fixed a plurality of connection assemblies 3 that are convenient for personnel to repair the concave of the outer tube...

Abstract

The invention discloses a double-layer heat-insulating pipe, which includes an inner pipe and an outer pipe, the outer pipe covers the outer side of the inner pipe, and a plurality of holes are fixed between the outer pipe and the inner pipe to facilitate repairing of the outer pipe. Connecting components, and the outer tube and the inner tube form multiple cavities through multiple connecting components. The present invention fills the cavity between the inner tube and the outer tube with macromolecular gas such as carbon dioxide for heat insulation, and at the same time utilizes detachable installation in the connection The repairing component inside the component moves in the convex groove, which realizes the repair of any dent in the outer tube, improves the thermal insulation performance of the outer tube, and does not need to disassemble the outer tube, which makes the repair convenient for personnel and shortens the construction period.

Description

technical field [0001] The invention relates to the technical field of double-layer heat-insulation pipes, in particular to a double-layer heat-insulation pipe. Background technique [0002] In life, it is necessary to transport hot water, hot steam and other energy media over long distances. During the transportation and process, energy loss should be avoided as much as possible to improve the transmission efficiency. At present, industrial and civil pipelines transport high-temperature media, often using metal pipes with asbestos layer and rubber layer structure, which has a certain heat insulation effect, but still needs to be improved. [0003] There are also double-layer heat-insulating pipes on the market now, and the insulation gas is filled in the middle of the double-layer heat-insulating pipes to achieve enhanced heat insulation effect. , will cause the double-layer heat insulation pipe to appear sunken in some areas, reducing the insulation effect, and it is extr...
