Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline heat preservation, in particular to a pipeline heat preservation structure. Background Art
[0002] When in use, pipeline heat preservation materials can provide heat preservation protection for pipelines. Existing pipeline heat preservation materials are directly wrapped outside the pipelines during pipeline production, and their convenience during production and installation is relatively poor. They can usually only be used in combination during pipeline construction. After pipeline construction, it is relatively difficult to remove, replace, or maintain them. Especially when the surrounding space is small and there are obstacles, maintenance is very difficult. During the later recycling of pipelines, when removing the surface heat preservation materials, the pipelines usually need to be fixed in position for disassembly and then removed. It is easy to damage the overall structure during removal, resulting in inability to be reused, and the combination efficiency with pipelines is also relatively low, and the production and processing costs are relatively high. For open-type heat preservation materials during combination, it is very difficult to ensure the sealing performance of the opening position, and the heat preservation safety during later use is relatively poor.
[0003] Document number CN118623144A discloses a heat preservation device applied to a heat pipeline. Its main structure is composed of multiple sleeve structures, and the overall structure is relatively complex. It can meet the combination requirements when used for large-sized heat pipelines, but for small-sized pipelines, the combination difficulty is relatively large, and the use cost is relatively high.
[0004] Document number CN118391544A discloses a heat preservation structure for a steam heat preservation pipeline. The main structure is relatively complex and needs to be connected in cooperation with a metal half shell. The overall combination efficiency is relatively low, and after the overall combination and pipeline construction are completed, it is impossible to replace the heat preservation materials alone.
[0005] Document number CN118110865A discloses a heat preservation structure for outdoor pipelines in building HVAC. The overall structure needs to be fastened with assembly components, and it is very difficult to ensure the sealing performance of the fastening connection position. The main heat preservation components are arranged inside the first protective cover and the second protective cover, and it is relatively troublesome to install and replace the heat preservation components.
[0006] Publication number CN118031015A discloses a pipeline heat preservation sleeve structure based on an outer sleeve type. During combination, it needs to be tightly cooperated with components such as bundling tapes. The space occupied by the fastening operation during fastening is relatively large, and the fastening efficiency is also relatively low. The fastening cooperation position adopts a direct fitting method for contact cooperation, and the overall sealing performance of the connection position is relatively average, and the combination tightness of the pipeline cooperation position during installation cannot be guaranteed. Summary of the Utility Model
[0007] The purpose of the present utility model is to provide a pipeline heat preservation structure, which adopts a combined detachable method for cooperative use. During use, it can be cooperatively connected with the pipeline at any time as needed. When in use, it is combined through a combined method, and the overall efficiency during cooperative use is higher. The combined position has two mating structures with different depths and shapes, ensuring better overall tightness during combination, higher heat preservation safety during use, and can be individually disassembled during later pipeline disassembly, and can be recycled and reused, with lower overall use cost, and is more energy-saving and environmentally friendly.
[0008] The technical solution of the present utility model is as follows:
[0009] A pipeline heat preservation structure, characterized in that: it includes a first heat preservation mating structure and a second heat preservation mating structure made of rigid heat preservation materials. Both the first heat preservation mating structure and the second heat preservation mating structure are semi-cylindrical structures. A pipeline mating hole is formed at the central position after the combination of the first heat preservation mating structure and the second heat preservation mating structure. A first combined sealing groove is provided on the mating surface of the first heat preservation mating structure and the second heat preservation mating structure. The first combined sealing groove is close to the pipeline mating hole. A second combined sealing groove is provided on the mating surface of the first heat preservation mating structure and the second heat preservation mating structure outside the first combined sealing groove. The depth of the first combined sealing groove is greater than that of the second combined sealing groove. The second heat preservation mating structure is respectively provided with a first combined stabilizing column and a second combined stabilizing column that cooperate with the first combined sealing groove and the second combined sealing groove. The first combined stabilizing column and the second combined stabilizing column are respectively the same shape as the first combined sealing groove and the second combined sealing groove. The cross-sectional shapes of the first combined sealing groove and the second combined sealing groove are different. The size of the outer opening position of the second combined sealing groove is smaller than the size in the inner width direction.
[0010] Further, the cross-sectional shape of the first combined sealing groove is an inverted trapezoidal structure, and the cross-sectional shape of the second combined sealing groove is a cylindrical structure.
[0011] Further, a sealing strip mating placement groove is provided outside the mating position of the first heat preservation mating structure and the second heat preservation mating structure.
[0012] The beneficial effects of the present utility model:
[0013] The utility model adopts a combined detachable method for cooperative use, and can be cooperatively connected with a pipeline at any time as needed during use. It is combined together by a combined method during use, and the overall efficiency during cooperative use is higher. It can be combined before pipeline construction or after pipeline construction, and the flexibility during combination is better. The combination position has two matching structures with different depths and shapes, ensuring better overall tightness during combination, higher heat preservation safety during use, and can be individually disassembled during later pipeline disassembly, and can be recycled and reused, with lower overall use cost. During use, multiple heat preservation structures with different diameters can be overlapped and sleeved together for use, which can meet the use requirements when applying to pipelines with higher heat preservation requirements.

[0021] Such as Figures 1 to 6As shown in the figure, a pipeline thermal insulation structure includes a first thermal insulation fitting structure 1 and a second thermal insulation fitting structure 2 made of rigid thermal insulation materials. Existing rigid materials can be used, such as polystyrene boards, silicate boards, etc. The first thermal insulation fitting structure 1 and the second thermal insulation fitting structure 2 are both semi-cylindrical structures. After the first thermal insulation fitting structure 1 and the second thermal insulation fitting structure 2 are combined, a pipeline fitting hole is formed at the central position, and the pipeline is fitted with this structure during use. A first combined sealing groove 3 is provided on the joint surface of the first thermal insulation fitting structure 1 and the second thermal insulation fitting structure 2. The first combined sealing groove 3 is close to the pipeline fitting hole. A second combined sealing groove 4 is provided on the joint surface of the first thermal insulation fitting structure 1 and the second thermal insulation fitting structure 2 at the outer side of the first combined sealing groove 3. The depth of the first combined sealing groove 3 is greater than that of the second combined sealing groove 4, ensuring better sealing stability at the inner side position, more reliable protection safety of the combined sealing structure between the inner and outer sides, and more guaranteed combined connection strength. The second thermal insulation fitting structure 2 is respectively provided with a first combined stabilizing column 5 and a second combined stabilizing column 6 that are fitted with the first combined sealing groove 3 and the second combined sealing groove 4. The first combined stabilizing column 5 and the second combined stabilizing column 6 have the same shape as the first combined sealing groove 3 and the second combined sealing groove 4 respectively, ensuring better tightness of the fit between them during fitting. The cross-sectional shapes of the first combined sealing groove 3 and the second combined sealing groove 4 are different. The size of the outer opening position of the second combined sealing groove 4 is smaller than the size in the inner width direction, so that this position can be snapped together during fitting, ensuring better overall tightness during fitting, higher connection strength, and a reliable anti-loosening effect. After the whole is fitted with the pipeline, it can also be fitted with clamp-like components for overall reinforcement combination. It is used in a combined and detachable manner. During use, it can be fitted and connected to the pipeline at any time as needed. During use, it is fitted together by a combined method, with higher efficiency during overall use. The combined position has two fitting structures with different depths and shapes, ensuring better overall tightness during combination, higher thermal insulation safety during use, and can be separately removed during later pipeline disassembly, and can be recycled and reused, with lower overall use cost. During use, it can ensure higher use safety of the pipeline and is more convenient during overall construction. During production and processing, it can be processed according to the shape of the pipeline as needed. For example, it can be processed into a bent pipe shape and can be combined and connected more precisely and conveniently with the bent pipe structure.
[0022] Preferably, the cross-sectional shape of the first combined sealing groove 3 is an inverted trapezoidal structure, and the cross-sectional shape of the second combined sealing groove 4 is a cylindrical structure, which has higher combined strength during mating, better combined tightness during overall mating, and better heat preservation and protection effect during later use.
[0023] Preferably, a sealing strip fitting groove is provided on the outside of the fitting position of the first heat preservation fitting structure 1 and the second heat preservation fitting structure 2. A separate sealing strip can be fitted and used at the outside position according to needs, which can further improve the moisture-proof and dust-proof effects of the overall fitting position.
[0024] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements or replacements can be made, and these improvements or replacements should also be regarded as the protection scope of the present invention.
