Description

Technical Field

[0001] The utility model relates to the technical field of pipeline heating, in particular to a pipeline heat preservation heating sheet with self-adhesive function. Background Technique

[0002] A pipeline refers to a device formed by connecting pipes, pipe connectors, valves, etc. for transporting gases, liquids, or fluids with solid particles. Some liquids or gases need to be transported or stored within a specific temperature range. For example, certain fluids in industries such as petroleum, chemical engineering, and medicine need to be at a certain temperature to maintain their properties and fluidity. Therefore, the pipelines used for transporting these liquids or gases require heating sheets for heating and heat preservation to keep the liquids or gases inside the pipelines within the set temperature range, thereby ensuring their quality and process requirements.

[0003] Most of the existing pipeline heating sheets are electric tracing tapes. However, the existing electric tracing tapes have a single structure and poor heat preservation and insulation effects, resulting in the heat generated during the operation of the electric tracing tape being very easy to lose to the outside, thus reducing the heating effect of the electric tracing tape. Moreover, during the use of the existing electric tracing tape wrapped around the circumferential side of the pipeline, the splicing joints are prone to loosening, and the use stability is poor.

[0030] Working principle: When the electric heating sheet 3 needs to be adhesively fixed at the required position on the circumferential side of the conveying pipe body 1, the installer first cleans and wipes off the dust and impurities on the circumferential side of the conveying pipe body 1, and then tears off the release layer 21 to separate it from the self-adhesive sheet 2. At this time, the electric heating sheet 3 can be adhesively fixed on the circumferential side of the conveying pipe body 1 by means of the self-adhesive sheet 2 for the electric heating sheet 3 on the energized working side to heat the conveying pipe body 1; during the process of adhesively fixing the self-adhesive sheet 2 on the circumferential side of the conveying pipe body 1, it is necessary to insert the splicing plug 61 into the corresponding splicing socket 65 so that the longitudinally spliced heat insulation component 4 has better integrity, and by inserting the connection card 62 into the connection card slot 64 (refer to Figure 1 or Figure 2), the connecting card 62 can be used to clamp and connect the extension blocks 63 on the upper and lower sides through the connecting card slots 64, thereby improving the connection stability of the upper and lower heat preservation components 4; during the use of the electric heating sheet 3, the internal isolation layer 41 made of aluminum foil composite fiberglass cloth not only has good heat insulation performance, but also has good airtight and waterproof sealing performance. The first heat preservation layer 42 made of aerogel felt has a low thermal conductivity, which can further improve the heat preservation ability of the internal isolation layer 41. At the same time, the second heat preservation layer 43 made of rubber and plastic foam heat preservation board has good heat insulation effect and low water absorption rate, which can further improve the heat preservation ability of the first heat preservation layer 42. The third heat preservation layer 44 made of sponge rubber has good sealing and heat insulation performance, which can further improve the heat preservation ability of the second heat preservation layer 43. Finally, the external isolation layer 45 made of aluminum foil composite fiberglass cloth not only has good heat insulation performance, but also has good airtight and waterproof sealing performance, which can further improve the heat preservation ability of the third heat preservation layer 44, thus preventing the heat generated by the electric heating sheet 3 from quickly dissipating to the outside during operation.
