Description

Technical Field

[0001] This utility model relates to the technical field of high temperature resistant fireproof insulation sleeves, specifically a high temperature resistant fireproof insulation sleeve. Background Technology

[0002] High-temperature resistant fireproof insulation jackets are flexible protective products that combine high-temperature resistance, fire resistance, flame retardancy, and thermal insulation. They are widely used in industrial equipment, pipelines, power systems, new energy devices, and other scenarios. They can effectively reduce heat loss, block high-temperature conduction, and delay the spread of fire in extreme situations such as fires, ensuring equipment safety and personnel protection.

[0003] Existing high-temperature fireproof insulation sleeves generally need to be produced in various sizes to accommodate pipes of different sizes. This requires multiple mold specifications, resulting in high production costs and poor compatibility. They also require the use of corresponding insulation sleeve models, which is inconvenient. Therefore, a high-temperature fireproof insulation sleeve is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature resistant, fireproof, and heat-insulating jacket to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A high-temperature resistant fireproof insulation sleeve includes a ceramic fiber layer, an aerogel composite layer, and a flame-retardant coated fabric. An aerogel composite layer is fixedly connected to the inner side of the ceramic fiber layer. A flame-retardant coated fabric is fixedly connected to the inner side of the aerogel composite layer. A support plate is fixedly connected to the inner side of the flame-retardant coated fabric. A support layer is fixedly connected to the end of the support plate away from the flame-retardant coated fabric. A pipe is provided inside the support layer. A limiting block is provided inside the pipe. A limiting rod is fixedly connected to the end of the limiting block away from the pipe, penetrating the ceramic fiber layer, aerogel composite layer, flame-retardant coated fabric, and support layer. A first limiting ring is fixedly connected to the outer side of the limiting rod, located between the flame-retardant coated fabric and the support layer. A spring is fixedly connected to the end of the first limiting ring away from the pipe, located outside the limiting rod. A second limiting ring is fixedly connected to the end of the spring away from the first limiting ring, located outside the limiting rod. A limiting disc is fixedly connected to the outer side of the ceramic fiber layer, located outside the limiting block. A handle is fixedly connected to the side of the limiting disc away from the limiting rod.

[0006] Preferably, there are four support plates, which are arranged in a cross shape between the flame-retardant coated fabric and the support layer, with the center of the support layer as the center.

[0007] Preferably, the first limiting ring, the spring, and the second limiting ring are a group, and there are several groups in total. The first limiting ring, the spring, and the second limiting ring are slidably disposed on the outside of the limiting rod.

[0008] Preferably, the outer shape of the limiting block matches the shape of the through groove on the pipe surface, and the outer dimensions of the limiting block match the dimensions of the through groove on the pipe surface.

[0009] Preferably, the side of the first limiting ring away from the second limiting ring is in contact with the support layer, and the side of the second limiting ring away from the first limiting ring is fixedly connected to the flame-retardant coated fabric.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by setting components such as a support plate, support layer, limiting block, limiting rod, spring, and limiting disc, the support plate and support layer can create a gap between the protective structure and the pipeline, further separating the fire source and the pipeline. At the same time, the limiting rod and spring are supported, and under the action of the spring, it is easy to lock and fix pipelines of various sizes, effectively improving the compatibility of the protective structure. Only one production mold is needed to meet the needs of pipelines of various sizes, saving costs. This solves the problem that existing high-temperature fireproof insulation sleeves generally need to be produced in multiple sizes to cope with the use of pipelines of different sizes, thus requiring multiple specifications of molds, resulting in high production costs and poor compatibility. They also require the use of corresponding models of insulation sleeves, which is inconvenient. 2. In this utility model, the first and second limiting rings can effectively limit the spring, making it easier for the spring to compress and rebound on an accurate trajectory. This guides the spring's movement trajectory and ensures that the limiting rod and limiting block can accurately fix the pipe. The handle allows for easier pulling of the limiting rod, facilitating the fixing of the pipe. Attached Figure Description

[0016] Please see Figure 1-3 This utility model provides a technical solution: A high-temperature resistant fireproof insulation jacket includes a ceramic fiber layer 1, an aerogel composite layer 2, and a flame-retardant coated fabric 3. The aerogel composite layer 2 is fixedly connected to the inner side of the ceramic fiber layer 1. The flame-retardant coated fabric 3 is fixedly connected to the inner side of the aerogel composite layer 2. A support plate 4 is fixedly connected to the inner side of the flame-retardant coated fabric 3. A support layer 5 is fixedly connected to the end of the support plate 4 away from the flame-retardant coated fabric 3. A pipe 6 is provided inside the support layer 5. A limiting block 7 is provided inside the pipe 6. A penetrating element is fixedly connected to the end of the limiting block 7 away from the pipe 6. Limiting rod 8 of layer 2, flame-retardant coated fabric 3 and support layer 5. A first limiting ring 9 located between flame-retardant coated fabric 3 and support layer 5 is fixedly connected to the outside of limiting rod 8. A spring 10 located outside of limiting rod 8 is fixedly connected to the end of the first limiting ring 9 away from pipe 6. A second limiting ring 11 located outside of limiting rod 8 is fixedly connected to the end of spring 10 away from the first limiting ring 9. A limiting disc 12 located outside of ceramic fiber layer 1 is fixedly connected to the end of limiting rod 8 away from limiting block 7. A handle 13 is fixedly connected to the side of limiting disc 12 away from limiting rod 8.

[0017] There are four support plates 4, which are arranged in a cross shape between the flame-retardant coated fabric 3 and the support layer 5, with the center of the support layer 5 as the center. The four support plates 4 can provide support while creating a movement gap between the spring 10 and the limiting rod 8. The first limiting ring 9, the spring 10 and the second limiting ring 11 are grouped together, and there are several groups in total. The first limiting ring 9, the spring 10 and the second limiting ring 11 are slidably arranged on the outside of the limiting rod 8, which effectively maintains the linkage between the spring 10 and the limiting rod 8, and facilitates the compression of the spring 10 by driving the limiting rod 8. The outer shape of the limiting block 7 matches the shape of the through groove on the surface of the pipe 6, and the outer size of the limiting block 7 matches the size of the through groove on the surface of the pipe 6. The matching size of the limiting block 7 and the through groove can effectively prevent the pipe 6 from rotating after it is fixed. The side of the first limiting ring 9 away from the second limiting ring 11 is in contact with the support layer 5, and the side of the second limiting ring 11 away from the first limiting ring 9 is fixedly connected to the flame-retardant coated fabric 3.

[0018] Workflow: When a high-temperature resistant fireproof insulation sleeve is required, first insert the pipe 6 into the support layer 5. Then, pull the handle 13 one full turn. The handle 13 drives the limiting rod 8 to move under the guidance of the ceramic fiber layer 1, aerogel composite layer 2, flame-retardant coated fabric 3, and support layer 5. At this time, the limiting rod 8 compresses the spring 10 through the first limiting ring 9, and supports and limits the other end of the spring 10 through the second limiting ring 11, ensuring the running trajectory of the spring 10. Then, continue to insert the pipe 6. At this time, the limiting block 7 will enter the through groove on the surface of the pipe 6. Under the compression of the spring 10, the limiting block 7 and the through groove on the surface of the pipe 6 are combined to assemble the overall protective structure with the pipe 6. The support plate 4 and the support layer 5 can make the protective structure A gap is created between the pipe 6 and the fire source, further separating the fire source from the pipe 6. At the same time, it supports the limiting rod 8 and the spring 10. Under the action of the spring 10, it is easy to lock and fix pipes 6 of various sizes, effectively improving the compatibility of the protective structure. The ceramic fiber layer 1, aerogel composite layer 2 and flame-retardant coated fabric 3 are set to protect the pipe 6 from fire and high temperature. The first limiting ring 9 and the second limiting ring 11 can effectively limit the spring 10, making it easy for the spring 10 to compress and rebound on the accurate trajectory. It plays a guiding role in the movement trajectory of the spring 10, ensuring that the limiting rod 8 and the limiting block 7 can accurately fix the pipe 6. The handle 13 can be set to pull the limiting rod 8 to move more easily, making it easier to fix the pipe 6.
