Abstract

The invention discloses a structure capable of reducing heat loss of a high-temperature pipeline. The structure comprises a lining barrel, a metal spun silk net, a thermal insulation block, a metal barrel, a metal wire and a high-temperature pipeline outer shell; the metal spun silk net wraps the outer surface of the lining barrel; the lining barrel is sleeved by the metal barrel; the thermal insulation block is filled between the metal barrel and the metal spun silk net; the metal wire is bundled on the outer surface of the metal barrel; the high-temperature pipeline outer shell is positioned on the outermost layer of the structure for reducing the heat loss of the high-temperature pipeline. The structure disclosed by the invention can be used for realizing thermal protection of the high-temperature pipeline, and the design thickness of the high-temperature pipeline can be reduced, and the heat loss of an air flow in the pipeline can be reduced.

Description

technical field

[0001] The invention relates to a structure for reducing heat loss of high-temperature pipelines. Background technique

[0002] In the design of conventional superb wind tunnels, it is necessary to heat the airflow to increase the total temperature of the gas and prevent the condensation of the gas during the rapid flow process. The temperature of the heated gas often reaches above 800°C. The stress cannot meet the design requirements. If high-temperature alloy materials are used, the cost will be greatly increased. The high-temperature pipeline structures that can be referred to in domestic superb wind tunnel equipment are mostly coated with zirconium-containing high-purity refractory fiber cotton on the outside or coated on the inside. Covered with refractory fiber cotton structure, the outer surface coating scheme can prevent the temperature of the pipe wall from spreading to the space and play a role in heat insulation, but high-performance materials or i...
