Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of heat preservation, specifically relates to a heat preservation sleeve. BACKGROUND

[0002] Pipe insulation is an important energy-saving measure in industry, construction, and energy systems, with multiple significant advantages. First, insulation can effectively reduce heat loss or cold loss. By using materials with low thermal conductivity (such as rock wool, glass wool, polyurethane, etc.), the heat exchange between the inside and outside of the pipe can be greatly reduced, allowing the transported medium (such as hot water, steam, chilled water, etc.) to maintain a stable temperature, thereby reducing energy waste and lowering operating costs. Second, insulation can prevent condensation and corrosion on the surface of the pipe. When transporting low-temperature medium, the outer wall of the pipe is prone to condensation due to temperature difference, leading to corrosion or mold growth. Insulation prevents the contact between moisture and the pipe, extending the service life of the pipe. In addition, insulation can improve safety by preventing burns from exposed high-temperature pipes or freezing accidents in low-temperature pipes, especially in the fields of chemical industry and heating and ventilation. In terms of environmental protection, reducing energy consumption directly reduces carbon emissions and helps achieve the "double carbon" goal. Finally, insulation can optimize system operation stability, such as maintaining constant steam pressure and ensuring refrigeration efficiency, ensuring the reliability of the process or building environment. In summary, pipe insulation has economic, safety, environmental, and long-term value, and is an indispensable part of modern facilities.

[0003] The existing heat preservation sleeve uses sewing or magic tape to fix the joint of the heat preservation sleeve when installing it on the pipe. For pipes of different diameters, special diameter heat preservation sleeves are usually provided to ensure the heat preservation of the corresponding diameter pipes.

[0004] However, the use of sewing or magic tape to fix the joint of the heat preservation sleeve can result in poor sealing effect at the joint, leading to a large amount of heat exchange with the outside world. Different diameter pipes must match the corresponding specification of the heat preservation pipe, and it is difficult to predict the damage location and length of the pipe heat preservation sleeve during later maintenance, making it difficult to prepare the appropriate specification of the heat preservation sleeve. When the heat preservation sleeve of a certain diameter is lacking during construction, it needs to be temporarily purchased, resulting in an increase in maintenance period. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0040] like Figures 1-5 As shown, this utility model provides an insulation sleeve, including: insulation sleeve body 1, first Velcro 2 and first sealing filler 3.

[0041] The insulation sleeve body 1 is used to surround the outside of the pipe and includes a first splicing end and a second splicing end; the first hook and loop fastener 2 includes a first hook and loop hook face 21, a first overlapping block 22 and a first hook and loop rough face 23; the first hook and loop hook face 21 is fixed to the outside of the first splicing end of the insulation sleeve body 1; the first overlapping block 22 includes a first fixing part 221 and a first overlapping part 222, the first fixing part 221 is fixed to the outside of the second splicing end of the insulation sleeve body 1, and the first overlapping part 222 extends out of the second splicing end and extends to the outside of the first splicing end; the first hook and loop rough face 23 is provided on the side of the first overlapping part 222 close to the first hook and loop hook face 21 and is used to bond with the first hook and loop hook face 21; the first sealant 3 is provided on the first overlapping part 222 and is located at the joint between the first splicing end and the second splicing end when the first hook and loop rough face 23 is bonded to the first hook and loop hook face 21.

[0042] When using this insulation sleeve to insulate the pipeline, the main body 1 of the insulation sleeve is placed around the outside of the pipeline. At this time, the first splicing end and the second splicing end of the main body 1 of the insulation sleeve are joined together. Since the first splicing end of the main body 1 of the insulation sleeve is provided with a first hook and loop fastener 21, and the second splicing end of the main body 1 of the insulation sleeve is provided with a first overlapping block 22, which extends out of the second splicing end and extends to the first overlapping part 222 outside the first splicing end, the first hook and loop fastener 23 is provided inside. Therefore, the first hook and loop fastener 23 can be overlapped onto the first hook and loop fastener 21 to connect the first splicing end and the second splicing end of the insulation sleeve 1 together. However, since only the outer layer of the first overlapping block 22 blocks the seam between the first splicing end and the second splicing end, the heat inside the pipeline will exchange with the outside through the seam between the first splicing end and the second splicing end.

[0043] The first caulking filler 3 is arranged on the first lap joint 222, and when the first magic tape rough surface 23 is bonded to the first magic tape hook surface 21, the first caulking filler 3 is located at the joint between the first splicing end and the second splicing end. The first caulking filler 3 is blocked at the joint between the first splicing end and the second splicing end, which can reduce heat exchange between the heat in the pipeline and the outside, and improve the heat preservation effect.

[0044] In order to ensure that the first caulking filler 3 has a good blocking effect, the first caulking filler 3 protrudes from the plane where the inner side surface of the first magic tape rough surface 23 is located, that is, when the first magic tape rough surface 23 is bonded to the first magic tape hook surface 21, a certain pressure can be applied to the first caulking filler 3 to ensure that the first caulking filler 3 blocks the joint between the first splicing end and the second splicing end.

[0045] In this example, the inner side and the outer side of the first splicing end and the second splicing end respectively refer to the inner wall of the cylinder, that is, the inner side, and the outer wall of the cylinder, that is, the outer side when the heat preservation sleeve body 1 is rolled up in a cylindrical shape.

[0046] Referring to Figure 3 In some optional embodiments, the heat preservation sleeve further comprises: a second magic tape 4 and a second caulking filler 5. The second magic tape 4 comprises a second magic tape hook surface 41, a second lap joint 42 and a second magic tape rough surface 43. The second magic tape hook surface 41 is fixed to the inner side of the first splicing end of the heat preservation sleeve body 1. The second lap joint 42 comprises a second fixed part 421 and a second lap joint 422. The second fixed part 421 is fixed to the inner side of the second splicing end of the heat preservation sleeve body 1, and the second lap joint 422 extends out of the second splicing end and extends to the inner side of the first splicing end. The second magic tape rough surface 43 is arranged on the side of the second lap joint 422 close to the second magic tape hook surface 41, and is used for bonding with the second magic tape hook surface 41. The second caulking filler 5 is arranged on the second lap joint 422, and when the second magic tape rough surface 43 is bonded to the second magic tape hook surface 41, the second caulking filler 5 is located at the joint between the first splicing end and the second splicing end.

[0047] In this embodiment, in order to make the heat preservation sleeve have better heat preservation effect and stability of the connection between the first splicing end and the second splicing end.

[0048] The second magic tape 4 and the second caulking filler 5 are arranged on the inner side when the heat preservation sleeve body 1 is rolled up in a cylindrical shape, and are arranged in the same way as the first magic tape 2 and the first caulking filler 3. That is, the second caulking filler 5 is arranged on the second lap joint 422, and when the second magic tape rough surface 43 is bonded to the second magic tape hook surface 41, the second caulking filler 5 is located at the joint between the first splicing end and the second splicing end. The second caulking filler 5 is blocked at the joint between the first splicing end and the second splicing end, which can reduce heat exchange between the heat in the pipeline and the outside, and improve the heat preservation effect.

[0049] Similarly, the second caulking filler 5 protrudes inwardly relative to the inner side surface of the second hook surface 43, that is, when the second hook surface 43 is attached to the second hook surface 41, a certain pressure can be applied to the second caulking filler 5 to ensure that the second caulking filler 5 seals the joint between the first joint end and the second joint end.

[0050] The first caulking filler 3 and the second caulking filler 5 are sealed by the first hook surface 2 and the second hook surface 4 on the outer side and the inner side of the joint between the first joint end and the second joint end, which plays a double role of blocking heat exchange.

[0051] Referring to Figure 3 In some optional embodiments, the second lap joint portion 422 is further provided with a second sealing filler 62, and the second sealing filler 62 is attached to the outer side of the second hook surface 43.

[0052] In the embodiment, the heat exchange between the inner side and the outer side of the heat preservation sleeve body 1 not only comes from the joint between the first joint end and the second joint end in the forward direction, but also comes from the gap between the second hook surface 43 and the second hook surface 41 after the two are attached. Therefore, in order to reduce the heat exchange between the inner side and the outer side of the heat preservation sleeve body 1 from the gap between the second hook surface 43 and the second hook surface 41, in the present solution, the second lap joint portion 422 is further provided with the second sealing filler 62, and the second sealing filler 62 is attached to the outer side of the second hook surface 43 and located at the outermost side of the second lap joint portion 422, that is, the second sealing filler 62 and the second caulking filler 5 are located on both sides of the second hook surface 43. The second sealing filler 62 also protrudes inwardly relative to the inner side surface of the second hook surface 43, that is, when the second hook surface 43 is attached to the second hook surface 41, a certain pressure can be applied to the second sealing filler 62 to ensure that the second sealing filler 62 seals the gap between the second hook surface 43 and the second hook surface 41, thereby improving the heat preservation effect.

[0053] Referring to Figure 1 In some optional embodiments, the second lap joint portion 422 includes two layers of fiber cloth, and the second sealing filler 62 and the second caulking filler 5 are filled between the two layers of fiber cloth.

[0054] In the embodiment, the second lap joint block 42 is made of two layers of fiber cloth, and the second sealing filler 62 and the second caulking filler 5 are filled between the two layers of fiber cloth. The second sealing filler 62 and the second caulking filler 5 are made of thermal insulation materials. Since the other parts of the second lap joint block 42 are only two layers of fiber cloth, the places where the second sealing filler 62 and the second caulking filler 5 are arranged naturally protrude inward relative to the inner side surface of the second magic tape rough surface 43. When the second magic tape rough surface 43 is bonded to the second magic tape hook surface 41, a certain pressure can be applied to the second sealing filler 62 and the second caulking filler 5, so that the second sealing filler 62 and the second caulking filler 5 play a better sealing role.

[0055] Referring to Figure 2 In some optional embodiments, the first lap joint part 222 is further provided with a first sealing filler 61, and the first sealing filler 61 is arranged on the outer side of the first magic tape rough surface 23.

[0056] Similarly, there is a gap between the first magic tape rough surface 23 and the first magic tape hook surface 21. In order to reduce the heat exchange between the inner side and the outer side of the thermal insulation sleeve main body 1 at the gap between the first magic tape rough surface 23 and the first magic tape hook surface 21, in the present scheme, the first sealing filler 61 is arranged on the first lap joint part 222, and the first sealing filler 61 is arranged on the outer side of the first magic tape rough surface 23 and located at the outermost side of the first lap joint part 222, that is, the first sealing filler 61 and the first caulking filler 3 are located on both sides of the first magic tape rough surface 23. The first sealing filler 61 also protrudes inward relative to the inner side surface of the first magic tape rough surface 23, that is, when the first magic tape rough surface 23 is bonded to the first magic tape hook surface 21, a certain pressure can be applied to the first sealing filler 61, so as to ensure the sealing of the gap between the first magic tape rough surface 23 and the first magic tape hook surface 21 by the first sealing filler 61, thereby improving the thermal insulation effect.

[0057] In some optional embodiments, the first lap joint block 22 includes two layers of fiber cloth, and the first sealing filler 61 and the first caulking filler 3 are filled between the two layers of fiber cloth.

[0058] In the present embodiment, the first lap joint block 22 and the second lap joint block 42 have the same structure, and the first sealing filler 61 and the first caulking filler 3 are also arranged between the two layers of fiber cloth and play the same role as the second sealing filler 62 and the second caulking filler 5. Here, it will not be described one by one.

[0059] In some optional embodiments, the first splicing end of the thermal insulation sleeve main body 1 is provided with a main body groove 11, and the second splicing end is provided with a main body protruding part 12 corresponding to the main body groove 11.

[0060] In the embodiment, the main body groove 11 is arranged at the middle of the first splicing end, and the main body protrusion 12 corresponding to the main body groove 11 is arranged at the middle of the second splicing end, so as to increase the length of the joint between the first splicing end and the second splicing end, increase the difficulty of passing through the joint inside and outside the main body 1 of the heat preservation sleeve, and improve the heat preservation effect.

[0061] Referring to Figure 4 and Figure 5 , in some optional embodiments, the main body 1 of the heat preservation sleeve comprises the cover layer 13, the heat preservation layer 14 and the cover layer 13 arranged in sequence, and the main body groove 11 and the main body protrusion 12 are arranged at two ends of the heat preservation layer 14.

[0062] In the embodiment, the cover layer 13 is made of fiber cloth, the heat preservation layer 14 is made of ceramic glass fiber cotton or aerogel felt, and the thickness of the heat preservation layer 14 is greater than the thickness of the cover layer. The main body groove 11 and the main body protrusion 12 are arranged at two ends of the heat preservation layer 14. When the two ends of the heat preservation layer 14 are butted, the length of the joint of the two ends of the heat preservation layer 14 is increased, so as to increase the difficulty of heat exchange and improve the heat preservation effect.

[0063] As shown in Figure 6 and Figure 7 , in some optional embodiments, the heat preservation sleeve further comprises a plurality of splicing blocks 7, each splicing block 7 comprises a splicing block main body 71, an outer side Velcro 72 and an outer side caulking filler 73, and the lengths of the splicing block main bodies 71 of the splicing blocks 7 are different. The outer side Velcro 72 has the same structure as the first Velcro 2, and the outer side caulking filler 73 has the same structure as the first caulking filler 3.

[0064] In the embodiment, the splicing block main body 71 of each splicing block 7 has the same structure as the main body 1 of the heat preservation sleeve, and only the length after unfolding is different. The length of the splicing block main body 71 of each splicing block 7 is also different. The outer side Velcro 72 has the same structure as the first Velcro 2, and the connection and relative relationship between the outer side Velcro 72 and the splicing block main body 71 are the same as the connection and relative relationship between the first Velcro 2 and the main body 1 of the heat preservation sleeve. The outer side caulking filler 73 has the same structure as the first caulking filler 3, and is arranged at the same position on the outer side Velcro 72 as the first caulking filler 3 arranged on the first Velcro 2. The outer side Velcro 72 also has an outer side caulking filler arranged on the outer side Velcro 72. Details are not described here.

[0065] Referring to Figure 7 , in addition, the splicing block 7 further comprises an inner side Velcro 74 and an inner side caulking filler 75, which have one-to-one correspondence with the second Velcro 4 and the second caulking filler 5. Details are not described here.

The inner side magic tape 74 comprises an inner side magic tape hook face 741, an inner side lap joint block 742 and an inner side magic tape flet 743.

[0067] In some optional embodiments, the middle part of one end of the splicing block body 71 is provided with a splicing block groove 711, and the middle part of the other end is provided with a splicing block protruding part 712 corresponding to the splicing block groove 711.

[0068] In the present embodiment, the splicing block groove 711 is the same as the main body groove 11, and the splicing block protruding part 712 has the same structure as the main body protruding part 12, so that the heat preservation sleeve main body 1 and the splicing block body 71 of any splicing block 7 can be connected in use. When connected, the splicing block protruding part 712 of the splicing block 7 extends into the main body groove 11 of the heat preservation sleeve main body 1, and the main body protruding part 12 of the heat preservation sleeve main body 1 extends into the splicing block groove 711 of the splicing block body 71. The length of the entire heat preservation sleeve is extended.

[0069] Referring to Figure 6 In actual use, the splicing block body 71 and the heat preservation sleeve main body 1 of different lengths can be selected according to the needs to adapt to the needs of different diameter pipelines. After the heat preservation sleeve main body 1 and the splicing block body 71 are spliced together, the outer side magic tape flet 723 is pasted on the first magic tape hook face 21, the outer side caulking filler 73 is blocked at the joint between the splicing block body 71 and the heat preservation sleeve main body 1, the first magic tape flet 23 is pasted on the outer side magic tape hook face 721, and the first caulking filler 3 is located at the other joint between the splicing block body 71 and the heat preservation sleeve main body 1. The outer side joint is blocked by the outer side caulking filler 73 and the first caulking filler 3.
