Building thermal insulation pipe

Abstract

The invention relates to a building thermal insulation pipe which comprises an anti-seismic outer cylinder, a positioning pipe, thermal insulation foam and a thermal insulation inner layer, the positioning pipe is arranged in the anti-seismic outer cylinder, the thermal insulation foam is arranged in the positioning pipe, and the thermal insulation inner layer is arranged in the thermal insulationfoam. Through the building thermal insulation pipe, the problems that upper-layer landfill and external pressure extrude the outer wall of a traditional thermal insulation pipe, the thermal insulation pipe is extremely prone to deformation, the thermal insulation pipe is broken seriously, a medium leaks, normal conveying is affected, the leaked medium easily pollutes soil, the traditional thermalinsulation pipe usually adopts an inner-layer and outer-layer thermal insulation structure, the thermal insulation effect is common, heat exchange between the medium in the pipe and the outside is easy, heat loss is caused, and the temperature of the medium is reduced, especially in places with the low room temperature are solved.

Description

technical field [0001] The invention relates to the field of thermal insulation pipes, in particular to a building thermal insulation pipe. Background technique [0002] Insulation pipe, a kind of pipeline used for liquid, gas and other media transportation, is often used in the construction field. When the existing insulation pipeline is implemented, it is usually realized by pre-buried underground. However, in the traditional insulation pipe installation After that, some problems are often encountered in the actual environment: [0003] 1. The upper layer of landfill and external pressure will squeeze the outer wall of the traditional insulation pipe, which will easily cause the insulation pipe to deform. In severe cases, the insulation pipe will be broken, causing the medium to leak out and affecting the normal transportation. The vented medium is easy to pollute the soil; [0004] The traditional insulation pipe usually adopts the "inner and outer layer" insulation str...

AI Technical Summary

Problems solved by technology

[0003] 1. The upper layer of landfill and external pressure will squeeze the outer wall of the traditional insulation pipe, which will easily cause the insulation pipe to deform. In severe cases, the insulation pipe will be broken, causing the medium to leak out and affecting the normal transportation. The vented medium is easy to pollute the soil;

[0004] The traditional insulation pipe usually adopts the "inner and outer layer" insulation structure, and the insulation effect is average. The medium in the tube is easy to exchange heat with the outside world, resulting in heat loss and lowering the temperature of the medium, especially in places where the room temperature is extremely low.
