Description

Technical Field

[0001] The utility model relates to the technical field of sleeve compensators, in particular to a heat preservation device for sleeve compensators. Background Art

[0002] As an important component of the industrial piping system, the compensator is mainly used to compensate for the internal stress and deformation of the pipeline caused by temperature changes, so as to ensure the normal operation of the entire piping system. Since high-temperature media often need to be transported in industrial production, if the compensator does not have good insulation measures, it will face the following problems: 1. Energy waste: The transported high-temperature medium will produce heat conduction to the surrounding environment of the compensator, causing the temperature of the surrounding area to rise, resulting in energy waste. 2. Reduced relief effect: High temperature causes the pipeline to expand, resulting in loss of effect, and the compensator cannot play its due role. 3. Reduced service life: In a high temperature environment for a long time, the compensator is susceptible to thermal expansion and repeated stress, resulting in a shortened service life. Therefore, it is very necessary to insulate the compensator;

[0003] However, the existing sleeve compensators are either asymmetrical in structure or thin at both ends and thick in the middle. Such a structural design is not convenient for the installation of the insulation device. Moreover, the insulation device is mainly wrapped in layers and filled with foam, which makes the operation too cumbersome. Utility Model Content

[0029] Specifically, the outer edge of the ring plate of the retractor 1 is flush with the inner edges of the outer ring plates of the left sleeve 3 and the right sleeve 4 , which facilitates the installation of the ring plate of the retractor 1 .

[0030] Specifically, Figure 1 As shown, the inner thermal insulation telescopic sleeve 7 is a bending and stretching structure, and annular surfaces are provided at both ends of the inner thermal insulation telescopic sleeve 7. The annular surfaces are glued and fixedly connected to the inner ring plate 6, which is easy to install. The inner thermal insulation telescopic sleeve 7 telescopes and expands as the telescope 1 expands and contracts.

[0031] Specifically, Figure 1 As shown, there is a gap between the annular surface and the first screw rod 2, so that the first screw rod 2 and the nut can be screwed and fixed, and the inner thermal insulation telescopic sleeve 7 is installed without blocking the first screw rod 2.

[0032] Specifically, the inner thermal insulation expansion sleeve 7 and the outer thermal insulation sleeve 8 are made of aerogel thermal insulation felt, aluminum silicate thermal insulation wool or glass wool, which are existing materials and are easy to use.

[0034] First, insert the main body of the expansion joint 1 into the inner cavity of the left sleeve 3 and the right sleeve 4, and then weld the ring plates with the first screw 2 installed at both ends of the expansion joint 1. The first screw 2 passes through the through-hole of the inner ring plate 6 and is tightened and fixed with the nut. The entire sleeve compensator has a symmetrical structure, and is thick on the outside and thin on the inside. In this way, the inner thermal insulation expansion sleeve 7 is installed in the recessed position of the sleeve compensator, that is, on the outside of the expansion joint 1, and the two ends of the inner thermal insulation expansion sleeve 7 are fixed to the inner ring plate 6.
