Vacuum tube with inner insulating layer

Abstract

The invention discloses a vacuum tube with an inner insulating layer and a schematic diagram of the vacuum tube. An insulating coating layer is coated on the outer wall of an inner tube of the vacuum tube, an insulating layer is arranged between the inner tube and an outer tube, and energy on the inner tube can be prevented from directly irradiating to the inner wall of the outer tube and can be absorbed and discharged to the atmosphere by the outer tube. The vacuum tube has the advantages of good pressure resistance, high corrosion resistance, stable vacuum degree, less proneness to damage and the like, and is better in heat and coldness insulation as compared with common vacuum tubes, and energy loss in steam, cold air and hot water delivery is reduced. Besides, the vacuum tube is simple in structure.

Description

technical field [0001] The invention relates to a pipeline, in particular to a vacuum pipeline with a thermal insulation layer. Background technique [0002] At present, pipelines are widely used, especially in many industries such as chemical industry, light industry, and medical treatment. It is very common to use pipelines to transport steam and air-conditioning. However, when the pipeline is used to transmit steam, cold air or hot water, whether it is wrapped with asbestos or gypsum, its heat insulation or cold insulation performance is extremely poor, especially when it is transmitted over a long distance, it will consume a lot of energy, thereby reducing production efficiency. Therefore, people use ordinary vacuum tubes to transmit cold and hot air. Although the effect is better than that of asbestos and gypsum wrapped pipes, the vacuum degree of ordinary vacuum tubes is not high, and the metal partitions at both ends of the vacuum tubes dissipate more energy. A consi...

Problems solved by technology

Therefore, people use ordinary vacuum tubes to transfer hot and cold air. Although the effect is better than that of asbestos and gypsum wrapped pipes, the vacuum degree of ordinary vacuum tubes is not high, and the metal partitions at both ends of the vacuum tubes dissipate more energy. A considerable amount of energy will be lost

[0003] So far, the vacuum pipelines made with inner heat insulation layer have not been seen at home and abroad, and there are no records in patent documents.
