It can be made through a special process after careful design and mapping according to the specific shape of the pipeline or equipment and its use environment. It can be used for the insulation of pipelines of different temperatures and shapes and various hot and cold equipment.

[0003] At present, most of the insulation covers in the prior art adopt detachable insulation covers. Although such detachable insulation covers can be easily installed and disassembled, and have good antifreeze and heat preservation effects, they are often limited in use due to the flexible material of their structure. That is, under the influence of uncertain factors such as outdoor environment and strong wind, the insulation covers made of flexible materials often do not have good pressure resistance, and are prone to certain deformation or even damage, which affects the heat preservation effect and cannot provide good protection for the internal pipes. This is particularly important for pipes arranged at the root of the wall close to the ground or pipes often arranged near the construction site. Utility Model Content

DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0020] See also Figure 1-3 The present embodiment relates to a flexible pressure-resistant thermal insulation jacket 1, comprising a thermal insulation jacket 1 body consisting of a multilayer structure of an inner lining 11, an intermediate thermal insulation layer 12 and an outer protective layer 13. A plurality of protective components 2 are arranged around the thermal insulation jacket 1 body. The protective components 2 include an arc-shaped inner protective plate 21 and an outer protective plate 22. The inner protective plate 21 is placed between the inner lining 11 and the intermediate thermal insulation layer 12, and the outer protective plate 22 is placed between the intermediate thermal insulation layer 12 and the outer protective layer 13. The outer protective plate 22 and the inner protective plate 21 are connected by a plurality of compression springs 3.

[0021] Specifically in this embodiment, the specific installation method of this flexible pressure-resistant heat-insulating sheath 1 can be found in Figure 1 As shown, its internal structure can be found in Figure 2As shown, the main body of the thermal insulation jacket 1 adopts a traditional detachable and multi-layer structure to be sleeved on the outside of the pipe 100, and its lining 11 contacts the outer wall of the pipe 100 at the required installation position. The length of the main body of the thermal insulation jacket 1 can be adapted to the specific length of the required installation pipe 100 according to specific usage requirements. At the same time, the unfolded length of the main body of the thermal insulation jacket 1 and the multiple groups of protective components 2 arranged around it are adapted to the size of the specific pipe 100 at the required installation position. After the thermal insulation jacket 1 is installed, during the protection process, it is affected by the uncertainties of the outdoor environment and weather such as strong winds, and small-scale rockfall or falling objects occur within a certain range. The protective components 2 in the main body of the thermal insulation jacket 1 can play a certain compressive and protective role on the pipe 100 when such a situation occurs, that is, the outer protective plate 22 placed between the middle insulation layer 12 and the outer protective layer 13 is subjected to a certain pressure, and can be expanded and contracted within a certain range under the elastic action of multiple groups of compression springs 3, so that the outer protective plate 22 can slide in the corresponding position in the main body of the thermal insulation jacket 1. At the same time, the inner protective plate 21 placed between the inner lining 11 and the middle thermal insulation layer 12 can play a certain reverse supporting force under the elastic force of the multiple groups of compression springs 3, thereby cooperating with the outer protective plate 22 to make it have a certain buffering and shock-absorbing function. This kind of thermal insulation jacket 1 main body has a certain pressure resistance under the action of the protective component 2, so it is not affected by the specific position and arrangement of the external pipeline 100. While ensuring the thermal insulation effect, it can also play a certain protective effect on the pipeline 100 at the corresponding position, further reducing the unnecessary influence on the thermal insulation effect or pipeline 100 of the thermal insulation jacket 1 caused by uncertain factors such as the external environment and weather, and the thermal insulation jacket 1 main body can undergo a certain deformation process under the action of its protective component 2 and has a certain buffering effect. At the same time, its outer protective plate 22 cooperates with the outer protective layer 13 to make the outer wall of the thermal insulation jacket 1 main body not easy to be damaged, further improving the thermal insulation effect and the stability of use while extending the service life.

[0022] The arc-shaped inner protective plate 21 and outer protective plate 22 are both made of elastic material. The inner protective plate 21 and outer protective plate 22 made of elastic material can further improve the protective effect, can undergo elastic deformation within a certain range and are not prone to breakage or damage, thereby further improving the buffering and shock absorption effects. In addition, it is also convenient for the installation of such thermal insulation jacket 1. During the installation process, the inner protective plate 21 and the outer protective plate 22 can undergo a certain deformation, thereby better fitting the outer wall of the pipe 100 and improving the thermal insulation effect.

[0023] A plurality of through holes 211 are opened and evenly distributed on the inner protective plate 21. The inner protective plate 21 placed between the inner lining 11 and the middle thermal insulation layer 12, together with the plurality of through holes 211 opened and evenly distributed thereon, ensures the thermal insulation effect while making the inner lining 11 that fits the outer wall of the pipe 100 have good air permeability relative to the main body of the thermal insulation jacket 1, thereby reducing the unnecessary influence of moisture or water vapor generated by the outer wall of the pipe 100 on the pipe 100 and the main body of the thermal insulation jacket 1 during use. In addition, the through holes 211 cooperate with the middle thermal insulation layer 12 to further increase the contact area, thereby further improving the thermal insulation effect.

[0024] A protective layer 4 for buffering and shock absorption is arranged in the cavity formed by connecting the inner protective plate 21 and the outer protective plate 22 through multiple groups of compression springs 3. The protective layer 4 can provide additional buffering and shock absorption effects while also playing a certain protective role for the multiple groups of compression springs 3, thereby reducing the probability of deformation or even damage of the compression springs 3 during long-term use. In addition, the protective layer 4 also plays a certain protective role for the inner protective plate 21 in the main body of the thermal insulation jacket 1, thereby further improving the supporting stability and thermal insulation effect of the main body of the thermal insulation jacket 1.

[0025] The protective layer 4 is filled with any material of flexible material or elastic material. The protective layer 4 can be filled with flexible material or elastic material according to specific usage requirements. The flexible material can be thermal insulation cotton. The protective layer 4 filled with thermal insulation cotton forms a new intermediate thermal insulation layer 12, thereby further improving the thermal insulation performance of the main body of this thermal insulation jacket 1; the elastic material can be made of any structure of a buffer pad or a rubber pad, thereby further improving the buffering and shock absorption effect of the protective component 2, and improving the stability of this thermal insulation jacket 1 during use.

[0026] The insulation jacket 1 has a main body in which adjacent protective components 2 are provided with partitions 5 to form a plurality of independent cavities. Figure 3 As shown, the setting of the partition net 5 can ensure that adjacent protection components 2 do not interfere with each other during the protection process, and the independent cavities formed by the partition net 5 can also avoid the displacement of the protection components 2, thereby ensuring the best protection effect of the protection components 2 and further improving the protection stability. In addition, the setting of the partition net 5 can produce a certain deformation process while ensuring the uniformity and uniformity of the internal temperature circulation.

[0027] Openings 14 are provided at corresponding positions of the main body of the thermal insulation jacket 1 on both sides of the inner protective plate 21 and the outer protective plate 22, and matching protective covers 6 are provided at the openings 14 through detachable structural covers. The protective covers 6 can be provided at the openings 14 using detachable structural covers such as Velcro or straps, thereby facilitating the installation, removal and replacement of the protective component 2 through the openings 14, thereby improving convenience and flexibility during use.

Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
