Embodiment 1

[0011] Embodiment 1: As shown in Figure 1 and Figure 3, the heat-insulating vacuum tube includes a flange 1, a pipe body 3, and a casing 4, and among the flanges 1 at both ends of the heat-insulating vacuum tube, at least one flange 1 is provided with a stainless steel The continuous corrugated knot 2 forms a vacuum chamber 5 with the steel pipe body 3 and the steel casing 4. The steel pipe body 3 is equipped with a number of axial or radial continuous or discontinuous plastic support ribs, support rings, or support points 6, Supported on the inner wall of the steel casing 4.

Embodiment 2

[0012] Embodiment 2: As shown in FIG. 1 , it is basically the same as Embodiment 1, except that the flange 1 has continuous corrugated knots 2 and is matched with a rubber elastic washer 7 .

Embodiment 3

[0013] Embodiment 3: As shown in Figure 1, it is basically the same as Embodiment 1, the difference is that a foam insulation material 8 is placed in the vacuum chamber 5, and a metal foil film 9 is sprayed on the insulation material.

Abstract

This invention relates to a heat-preservation vacuum tube including a flange, a tube and a bushing, in which at least one flange is set with ripple joints in the flanges at both ends of the vacuum tube to form a vacuum cavity with the tube and the bushing, several axial and radial continuous or discontinuous support tendons, support loops or support points are supported on the inside wall of the bushing, and the ripple structure on the flange can improve its stress relation and the elastic pad inside can reduce resistance of pipelines and keeps warm at the end and welding lines are less.

Description

technical field [0001] The invention relates to a thermal insulation vacuum tube, in particular to a thermal insulation vacuum tube for transporting water or steam. Background technique [0002] Based on the Chinese patent with the authorized announcement number CN2395126Y, a utility model of a steel-sheathed steel high-temperature-resistant composite vacuum insulation pipe, which includes a working steel pipe, an inorganic insulation layer, an organic insulation layer, a protective layer, etc., has a complex structure and high operating costs At present, there are other types of vacuum insulation pipes, but they are difficult to manufacture, have more welds, and have higher costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects existing in the prior art, and provide a thermal insulation vacuum tube with simple structure, fewer welding seams, easy manufacture and low cost. [0004] In order to achie...
