Description

Technical Field

[0001] This utility model relates to the field of thermal insulation pipe technology, specifically a composite rubber and plastic thermal insulation sleeve. Background Technology

[0002] In industrial production and daily life, various pipelines are widely distributed for transporting different media, such as hot water, steam, and cold air. In many scenarios, pipeline insulation becomes a critical requirement. Traditional insulation materials and methods have many limitations. The installation of traditional insulation materials often requires professionals to use specific tools for complex operations, such as cutting, pasting, and binding, resulting in low installation efficiency and difficulty in ensuring the tightness and stability of the installation, further affecting the insulation quality. Based on these problems, the development of a composite rubber-plastic insulation sleeve has become an inevitable trend. It aims to overcome the shortcomings of traditional insulation materials and provide an efficient, durable, and convenient pipeline insulation solution to meet the increasingly high standards of pipeline insulation required by modern industry and daily life.

[0003] When the insulation sleeve cannot fit tightly against the pipe, an air gap will form between the pipe and the sleeve. Air is a poor conductor of heat, but these gaps will cause heat convection to intensify. Due to the lack of an effective tightening device, the insulation sleeve is prone to loosening and displacement, which requires frequent inspection and readjustment of the sleeve's position. Utility Model Content

[0004] The purpose of this utility model is to provide a composite rubber and plastic insulation sleeve. Through the cooperation mechanism between the tightening strap, the fastening block, and the Velcro, the installation and fixing of the sleeve on the pipeline is greatly facilitated. The fastening block rolls up the tightening strap, effectively eliminating any gaps that may exist between the sleeve and the pipeline, thereby greatly enhancing the insulation effect and preventing heat loss from the gaps. The sleeve can be easily installed through simple wrapping and pasting, significantly shortening the installation time. This easy-to-install, easy-to-disassemble, and reusable feature significantly reduces maintenance costs during long-term use and greatly simplifies the operation process.

[0005] To achieve the above objectives, a composite rubber-plastic insulation sleeve is provided, comprising: a protective layer, wherein a tightening strap and a fastening block are fixedly connected to the outer surface of the protective layer, and the fastening block retracts the tightening strap; a hook-and-loop fastener is fixedly connected to the upper surface of the tightening strap, and a hook-and-loop hook is fixedly connected to the side of the tightening strap away from the hook-and-loop fastener; the hook-and-loop fastener and the hook-and-loop hook are compatible. The tightening strap facilitates and quickly secures the sleeve, ensuring a tight wrap around the pipe, effectively reducing heat loss, enhancing insulation performance, and facilitating installation and disassembly. It is reusable, reduces maintenance costs and operational difficulty, and improves overall efficiency.

[0006] According to the aforementioned composite rubber-plastic insulation sleeve, the protective layer is woven from EPDM rubber, and an insulation layer is provided on the inner surface of the protective layer. The EPDM rubber woven protective layer has excellent weather resistance, aging resistance, and waterproof properties, and can resist external erosion for a long time, protecting the internal structure and reducing performance degradation and damage caused by environmental factors.

[0007] According to the aforementioned composite rubber-plastic insulation sleeve, the insulation layer is woven from a composite material consisting of nitrile rubber and polyvinyl chloride, and an adhesive layer is provided on the inner surface of the insulation layer. The composite insulation layer composed of nitrile rubber and polyvinyl chloride effectively blocks heat transfer, significantly reduces heat loss, maintains a stable temperature of the medium inside the pipeline, and saves energy.

[0008] According to the aforementioned composite rubber-plastic insulation sleeve, the adhesive layer is woven from a mixture of neoprene rubber and adhesive, and a rubber contact layer is provided on the inner surface of the adhesive layer. Utilizing the special properties of its mixed materials, the adhesive layer strongly bonds the various layers, forming a stable whole within the insulation sleeve. This ensures that each layer works collaboratively, effectively preventing interlayer separation or loosening, guaranteeing the continuity and reliability of insulation performance, and preventing insulation failure caused by structural instability.

[0009] According to the aforementioned composite rubber-plastic insulation sleeve, the rubber contact layer is woven from EPDM rubber, and a pipe is provided on the inner surface of the rubber contact layer. The rubber contact layer directly contacts the pipe, providing not only cushioning protection and reducing damage to the pipe from external impacts or friction, but also a certain degree of sealing performance, preventing moisture and other impurities from entering between the pipe and the insulation layer. This further maintains the integrity of the pipe and the effectiveness of the insulation layer, extending the overall service life of the pipe and the insulation sleeve.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model features a tightening strap, a fastening block, a hook and loop fastener, and a loop fastener hook side. Through the interaction mechanism between the tightening strap, the fastening block, and the loop fastener, it greatly facilitates the installation and fixing of the sleeve on the pipeline. The fastening block retracts the tightening strap, effectively eliminating any gaps between the sleeve and the pipeline, thus significantly enhancing the insulation effect and preventing heat loss through gaps. The sleeve can be easily installed through simple wrapping and pasting, greatly shortening installation time. This easy-to-install, easy-to-disassemble, and reusable feature significantly reduces maintenance costs during long-term use and greatly simplifies the operation process.

Water-based, protecting the internal structure, the inner surface of the protective layer 1 is provided with a heat insulation layer 4, which is woven from a composite material composed of nitrile rubber and polyvinyl chloride, effectively blocking heat transfer and playing a role in heat insulation. The inner surface of the heat insulation layer 4 is provided with an adhesive layer 3, which is woven from a mixture of neoprene rubber and glue, enhancing the adhesion with the rubber contact layer 2 and making the structure of each layer tightly bonded.

The inner surface of the rubber contact layer 2 is provided with the pipe 5.

[0021] Working principle: The rubber contact layer 2 is aligned with the pipe 5 requiring insulation, tightly wrapping the outer surface of the pipe 5. Adhesive from the adhesive layer 3 is evenly applied to the outer surface of the rubber contact layer 2. Then, the insulation layer 4 is placed over the adhesive layer 3 and pressed down appropriately to ensure a tight bond between the insulation layer 4 and the adhesive layer 3, thus creating an effective insulation barrier to block heat transfer. The protective layer 1 is then wrapped around the insulation layer 4, ensuring complete coverage. The protective layer 1 protects the internal structure from external environmental factors. The tightening strap 7 is then wrapped around the protective layer 1, ensuring the hook and loop sides 8 and 9 are aligned. The tightening strap 7 is then rolled up using the fastening block 6, adjusting its tightness until the protective layer 1 is tightly adhered to the insulation layer 4 and the entire insulation sleeve is securely fixed. The tightening strap 7 further secures the layers of the insulation sleeve, preventing loosening or displacement during use and ensuring the stability and reliability of its insulation performance.
