Heat preservation jacket for pipeline

Abstract

The heat preservation outer sleeve comprises a straight pipe A and a straight pipe B, a bent pipe is arranged between the straight pipe A and the straight pipe B, notches are formed in the positions of the straight pipe A, the straight pipe B and the bent pipe in a penetrating mode, clamping pieces are arranged in the notches to achieve combination of the straight pipe A, the straight pipe B and the bent pipe, and the straight pipe A, the straight pipe B and the bent pipe can deform to achieve opening and closing. Through the arrangement of the built-in air bag, intelligent adaptation and efficient sealing of pipelines with different pipe diameters are achieved. The inflated air bag can expand in a self-adaptive mode and is tightly attached to the outer walls of pipelines of various specifications, and a gap between a traditional heat preservation sleeve and the pipelines is eliminated. The elastic material of the air bag not only can compensate the unevenness of the surface of the pipeline, but also can form uniform radial pressure, so that all-directional dead-corner-free contact is ensured. The dynamic sealing mechanism effectively obstructs air convection, and the heat preservation efficiency is remarkably improved.

Description

Technical Field

[0001] This utility model relates to the technical field of thermal insulation jackets for pipelines, and in particular to a thermal insulation jacket for pipelines. Background Technology

[0002] Pipe insulation jackets are devices used to wrap pipes and reduce heat loss, widely used in industries such as petrochemicals, HVAC, and power. Their main function is to reduce heat loss from the medium inside the pipe, improving energy efficiency, while preventing condensation or freezing on the pipe surface. Traditional insulation jackets typically use fixed-size insulation material to wrap the pipe and secure it with straps or tape, but in practical applications, problems such as poor fit and incomplete sealing still exist. Currently, common pipe insulation technologies mainly include...

[0003] Pre-fabricated insulation materials such as cotton and rubber-plastic foam are used, cut to size according to the pipe dimensions, wrapped around it, and secured with metal cable ties or tape. The disadvantages are cumbersome installation, difficulty adapting to different pipe diameters or complex bends, and a tendency for poor fit leading to reduced insulation performance. Some systems consist of two halves of a rigid outer shell joined together and secured with bolts or clips. While easy to assemble and disassemble, the rigid structure makes it difficult to completely fit the pipe, especially at uneven surfaces or diameter changes, which can easily create thermal bridges and affect insulation performance. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a thermal insulation jacket for pipelines to solve the technical problems in the background technology.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a thermal insulation jacket for pipes, including a straight pipe A and a straight pipe B, with a bend between the straight pipe A and the straight pipe B. The straight pipe A, the straight pipe B, and the bend are all provided with slots. The inside of the slots is provided with snap-fit ​​components to realize the combination of the straight pipe A, the straight pipe B, and the bend. The straight pipe A, the straight pipe B, and the bend can all be deformed to realize opening and closing.

[0006] Both straight pipe A and straight pipe B have internal fillers, including airbags that are snapped into the inner walls of straight pipe A and straight pipe B. One side of the bend has an inflation structure for inflating the airbags. After the outer sleeve is fitted onto the pipe, the inflation structure makes close contact with the outer wall of the pipe.

[0007] Optionally, the snap-fit ​​component includes a snap fastener located on one side of the inner wall of the slot, and a slot adapted to the snap fastener is provided on the other side of the slot, with the snap fastener inserted into the slot.

[0008] Optionally, the lower end of the buckle has a triangular structure, and the cross-section of the slot has a T-shaped structure. After the buckle enters the slot, it contacts the side wall of the slot to fix the position.

[0009] Optionally, the outer periphery of the airbag is provided with a deformable connecting piece, the inner walls of the straight tube A and the straight tube B are provided with several female buckles, and one side of the curved tube is provided with a female buckle that engages with the female buckles.

[0010] Optionally, the inflation structure includes two inflation tubes located on the inner walls of straight tube A and straight tube B respectively, and a slot adapted to the inflation tube is provided on one side of the connecting piece, and the air inlet buckle of the airbag is connected to the slot.

[0011] Optionally, the ends of the two inflation tubes furthest from the airbag pass through straight tube A and straight tube B respectively and are connected to a connecting tube. One end of the connecting tube is provided with an air inlet, and one end of the air inlet is provided with an air nozzle.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention achieves intelligent adaptation and efficient sealing for pipes of different diameters through the built-in airbag. The inflated airbag expands adaptively, tightly fitting the outer wall of pipes of various specifications, eliminating gaps between the insulation sleeve and the pipe, as is common in traditional systems. The elastic material of the airbag not only compensates for unevenness on the pipe surface but also creates uniform radial pressure, ensuring omnidirectional, dead-angle-free contact. This dynamic sealing mechanism effectively blocks air convection, significantly improving insulation efficiency. Attached Figure Description

A snap-fit ​​component is provided inside the slot 4 to realize the combination of the straight pipe A1, the straight pipe B2, and the bend 3. The straight pipe A1, the straight pipe B2, and the bend 3 can all be deformed to realize opening and closing.

[0020] Both straight pipes A1 and B2 have internal fillers, including air bladders 5 that snap onto the inner walls of the pipes. One side of the bend 3 has an inflation structure for inflating the air bladders 5. After the outer sleeve is fitted over the pipe, the inflation structure ensures tight contact with the outer wall of the pipe. The built-in air bladders 5 enable intelligent adaptation and efficient sealing for pipes of different diameters. The inflated air bladders 5 expand adaptively, tightly fitting the outer wall of pipes of various specifications, eliminating gaps between the insulation sleeve and the pipe, as is common in traditional insulation systems. The elastic material of the air bladders 5 not only compensates for unevenness on the pipe surface but also creates uniform radial pressure, ensuring omnidirectional, dead-angle-free contact. This dynamic sealing mechanism effectively blocks air convection, significantly improving insulation efficiency.

[0021] In this embodiment, the snap-fit ​​component includes a snap fastener 8 located on one side of the inner wall of the slot 4, and a slot 9 adapted to the snap fastener 8 on the other side of the slot 4. The snap fastener 8 is inserted into the slot 9. The lower end of the snap fastener 8 has a triangular structure, and the cross-section of the slot 4 has a T-shaped structure. After the snap rod enters the slot 4, the snap fastener 8 contacts the side wall of the slot 4 to fix its position.

[0022] In this embodiment, the outer wall of the airbag 5 is provided with a deformable connecting piece, and the inner wall of the straight tube A1 and the straight tube B2 is provided with a plurality of male buckles 10. The side of the bent tube 3 is provided with a female buckle 11 that is engaged with the male buckles 10. By using the male buckles 10 and the female buckles 11, the airbag 5 can be installed into the straight tube A1 and the straight tube B2 to realize the maintenance of the airbag 5.

[0023] In this embodiment, the inflation structure includes two inflation tubes 12 located on the inner walls of straight tubes A1 and B2, respectively. A slot 4, adapted to the inflation tube 12, is provided on one side of the connecting piece. The air inlet buckle of the airbag 5 is connected to the slot 4. The inflation tubes 12 allow for inflation of the airbag 5 after it is installed in straight tubes A1 and B2, enabling the airbag 5 to inflate.

[0024] In this embodiment, the ends of the two inflation tubes 12 furthest from the airbag 5 pass through straight tube A1 and straight tube B2 respectively and are connected to a connecting tube 13. One end of the connecting tube 13 has an air inlet, and one end of the air inlet is equipped with an air nozzle 14. The inflation tubes 12 allow for simultaneous inflation of both airbags 5, and the air nozzle 14 is the existing swimming ring air nozzle, which is convenient for personnel to operate.
