Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline heat preservation, and particularly relates to a low-temperature pipeline heat preservation structure. Background Technique

[0002] A pipeline is a device connected by pipes, pipe connectors, valves, etc. for transporting gases, liquids, or fluids with solid particles. Usually, after the fluid is pressurized by a blower, compressor, pump, boiler, etc., it flows from the high-pressure part of the pipeline to the low-pressure part. It can also be transported by the pressure or gravity of the fluid itself. The uses of pipelines are very extensive and are mainly used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects, and various industrial installations.

[0003] Most of the interiors of low-temperature pipelines carry low-temperature liquids, and these liquids require a certain heat preservation structure during the process of flowing and transporting in the low-temperature pipelines to avoid the volatilization and diffusion of their temperatures. For this reason, we have proposed a low-temperature pipeline heat preservation structure. Content of the Utility Model

[0004] The purpose of the utility model is to provide a low-temperature pipeline heat preservation structure to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A low-temperature pipeline heat preservation structure includes a heat preservation layer. One side of the heat preservation layer is fixedly connected with a protective layer. One side of the protective layer is fixedly connected with a sealing layer. One end of the side surface of the sealing layer is fixedly connected with a wire storage block. A connecting belt is arranged inside the wire storage block. The bottom of the connecting belt is fixedly connected with a female velcro surface. The other end of the side surface of the sealing layer is fixedly connected with a connecting block. The top of the connecting belt is connected with a male velcro surface.

[0006] As a preferred implementation manner, a protective shell is sleeved on the side surface of the sealing layer. An arc-shaped groove is opened on the inner wall of the protective shell. A support block is fixedly connected inside the arc-shaped groove. The protective shell is made of bendable flexible plastic.

[0007] As a preferred implementation manner, a hollow groove is opened inside the connecting block and can be penetrated by the connecting belt.

[0008] As a preferred implementation manner, the heat preservation layer is made of polyurethane. The heat preservation layer and the protective layer are fixedly bonded by gel. The heat preservation layer made of polyurethane can insulate and heat the surroundings of the low-temperature pipeline, and has good resilience and heat insulation performance, and can be better installed on the low-temperature pipeline and closely fit with its surface.

[0009] As a preferred embodiment, the protective layer is made of polyether polyol. The protective layer and the sealing layer are fixedly bonded by gel. The protective layer adhered to the heat-insulating layer is made of polyether polyol, which can further improve the heat-insulating efficiency while protecting the heat-insulating layer.

[0010] As a preferred embodiment, the sealing layer is made of resin cloth, and the connecting belt is made of nylon cloth.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, by providing a heat-insulating layer made of polyurethane, heat insulation can be carried out around the low-temperature pipeline, and it has good resilience and heat insulation performance, can be better installed on the low-temperature pipeline and closely fit its surface. The protective layer adhered to the heat-insulating layer is made of polyether polyol, which can further improve the heat-insulating efficiency while protecting the heat-insulating layer.

[0020] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, a protective shell 9 is sleeved on the side surface of the sealing layer 3, an arc-shaped groove 10 is opened on the inner wall of the protective shell 9, a support block 11 is fixedly connected inside the arc-shaped groove 10, and the protective shell 9 is made of bendable flexible plastic.

[0021] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, a hollow groove is opened inside the connecting block 7 and can be penetrated by the connecting belt 5.

[0022] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, the heat preservation layer 1 is made of polyurethane, and the heat preservation layer 1 and the protective layer 2 are fixedly bonded by gel.

[0023] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, the protective layer 2 is made of polyether polyol, and the protective layer 2 and the sealing layer 3 are fixedly bonded by gel.

[0025] Working principle and usage process of the present utility model: The staff can first tightly wind the thermal insulation layer 1 around the low-temperature pipeline. The thermal insulation layer 1 made of polyurethane will have good resilience and heat insulation ability, and can firmly adhere to the periphery of the low-temperature pipeline. One side of the thermal insulation layer 1 is fixedly bonded with a protective layer 2 through gel. The protective layer 2 is made of polyether polyol and has good toughness and heat insulation. It can not only protect the thermal insulation layer 1 and the low-temperature pipeline, but also further improve the heat insulation efficiency. One side of the protective layer 2 is fixedly bonded with a sealing layer 3 through gel. The sealing layer 3 can not only seal and insulate the surface of the sealing layer 3, but also has a connecting block 7 installed on its side surface. The staff can draw out the connecting belt 5 from the wire storage block 4 and pass it through the connecting block 7, and adhere the hook surface 8 provided at the top of the connecting belt 5 to the loop surface 6 provided on its back. This will greatly increase the flexibility and adjustability of the installation of the thermal insulation structure. In addition, the staff can sleeved a protective shell 9 on the side surface of the sealing layer 3. Since the protective shell 9 is made of bendable flexible plastic and has a support block 11 provided in the arc-shaped groove 10 opened inside, the protective shell 9 can be prevented from deforming under the extrusion of the support block 11. The opening of the arc-shaped groove 10 also makes the protective shell 9 easier to take.
