As shown in fig. 1 and 2, the embodiment discloses a novel steam pipeline fixing support structure, including working tube 1, the outside cover of working tube 1 is equipped with outer tube 2, is provided with heat preservation 9 in the intermediate layer between working tube 1 and the outer tube 2, and heat preservation 9 is polyurethane insulation material, and the air bed 10 is left with the inner wall of outer tube 2 to the outer wall of heat preservation 9.
Be provided with a plurality of atress boards 3 for annular interval on the outer wall at work pipe 1 middle part, in this embodiment, each atress board 3 and the axis parallel arrangement of work pipe 1. The inner end of each stress plate 3 is welded with the outer wall of the working pipe 1, and the outer end of each stress plate 3 is welded with the inner wall of the outer sleeve 2. One side of the stress plate 3 is sequentially provided with a partition plate 4 and a first moisture exhaust pipe 5; the inner ring of the partition plate 4 is welded and sealed with the outer wall of the working pipe 1, and the outer ring of the partition plate 4 is welded and sealed with the inner wall of the outer sleeve 2; the first moisture exhaust pipe 5 is welded on the pipe wall of the outer sleeve 2, and the lower end of the first moisture exhaust pipe 5 is communicated with the air layer 10.
The air layer 10 functions roughly in four ways: firstly, once a pipeline leaks or dew exists, steam can be discharged from the moisture exhaust pipe to the outside along the air layer 10; secondly, the air layer 10 has a certain thermal resistance effect, also called as an air heat insulation layer, and the heat conductivity coefficient of air is relatively low; thirdly, when the buried pipe is installed, water cannot be prevented from entering due to various reasons, and when the steam pipeline runs, water can be heated and evaporated and can be discharged from the moisture discharge pipe to the outside through the air layer 10, so that water vapor is prevented from being accumulated; fourthly, since the steam pipe is expanded due to high temperature, the air layer 10 can protect the working pipe and the outer protection pipe from being damaged by extrusion when sliding relatively.
The main advantage function of the stress plate 3 is that the working pipe 1 can conduct stress to the outer sleeve 2 through the stress plate 3 when expanding under heat, so as to ensure the working quality and the service life of the fixed supporting structure. The first moisture exhaust pipe 5 is mainly used for exhausting steam water in the heat-insulating layer of the steam pipeline; the partition plate 4 is arranged between the moisture discharge pipe and the stress plate 3 and used for blocking the circulation of water vapor in different pipe sections.
