Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline protection, and particularly relates to a heat insulation sheath for a hot water pipeline. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for transporting gas, liquid or fluid with solid particles. A hot water pipeline, as the name suggests, refers to a pipeline for transporting hot water.

[0003] Some existing pipelines are often exposed to the outside during the process of transporting liquids. When encountering bad weather or being hit by objects, they may be damaged. Therefore, a pipeline protection cover is used.

[0004] During use, the pipe protective cover can wrap and protect the pipe in all directions, thereby preventing the pipe from direct contact with the outside and playing a certain protective role. However, the size of the traditional pipe protective cover is relatively fixed, so when the staff installs the protective cover on the pipe, they need to select the corresponding protective cover according to the size of the pipe itself, making the installation process of the protective cover relatively rigid. For this reason, we propose an insulating cover for hot water pipes. Utility Model Content

[0005] The purpose of the present invention is to provide a heat-insulating sheath for hot water pipes, so as to solve the problem in the above-mentioned background technology that the size of the pipe protective sheath is relatively fixed and the corresponding protective sheath needs to be selected according to the size of the pipe itself, thereby making the installation process of the protective sheath relatively rigid.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a thermal insulation sheath for a hot water pipe, comprising a temperature-sensitive color-changing layer, the top of the temperature-sensitive color-changing layer is fixedly connected to a high-temperature heat-resistant insulation layer, the top of the high-temperature heat-resistant insulation layer is fixedly connected to an anti-slip outer layer, the top of the anti-slip outer layer is fixedly connected to anti-slip particles, the top of the anti-slip outer layer is fixedly connected to a Velcro sub-surface, the bottom of the temperature-sensitive color-changing layer is fixedly connected to a Velcro mother surface, the top of the temperature-sensitive color-changing layer and the interior of the high-temperature heat-resistant insulation layer and the anti-slip outer layer are fixedly connected to a raised block, the raised block penetrates the high-temperature heat-resistant insulation layer and the anti-slip outer layer, the user first sticks the anti-slip outer layer on the surface of the hot water pipe, and then pulls the Velcro sub-surface to wrap the thermal insulation protective sheath around the surface of the hot water pipe as a whole. The Velcro sub-surface and the Velcro main surface on the back of the thermal insulation protective cover are bonded to each other, thereby completing the installation of the thermal insulation protective cover. During the installation of the thermal insulation protective cover, the elasticity of the anti-slip particles themselves makes the thermal insulation protective cover fit more tightly and is not easy to loosen, thereby effectively extending the service life of the thermal insulation protective cover. The high-temperature resistant insulation layer can insulate the heat emitted by the hot water pipe to prevent heat from dissipating, thereby reducing the loss of hot water circulating inside the pipe, playing an energy-saving, environmentally friendly and practical role. Finally, the temperature-sensitive color-changing layer can sense the temperature of the hot water pipe surface and change its own color, which can produce a warning effect for surrounding users, facilitate the use of users, and effectively improve practicality and convenience.

[0007] As a preferred embodiment, the temperature-sensitive color-changing layer is made of warp yarn, weft yarn and temperature-sensitive color paste, and its color changes with changes in ambient temperature.

[0008] As a preferred embodiment, the high temperature resistant insulation layer is a polyimide film tape, which is based on polyimide film and coated with high performance silicone pressure sensitive adhesive on one side. It can be composited with or not composited with a single-sided fluoroplastic release material.

[0009] As a preferred embodiment, the anti-slip outer layer is woven from warp flax fibers and weft flax fibers.

[0010] As a preferred embodiment, the Velcro sub-surface is adapted to the Velcro main surface, and the anti-slip particles are distributed in a front-to-back parallel array to the top of the anti-slip outer layer, and the anti-slip particles are made of rubber, plastic and other materials.

[0011] As a preferred embodiment, the raised block is made of warp yarn, weft yarn and thermochromic color paste, and its color changes with the change of ambient temperature. It is located on the top of the thermochromic layer and passes through the high temperature resistant insulation layer and the anti-slip outer layer.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model is used by a worker who first sticks the non-slip outer layer on the surface of the hot water pipe, and then pulls the Velcro surface to wrap the thermal insulation protective sleeve around the surface of the hot water pipe, and makes the Velcro surface and the Velcro mother surface on the back of the thermal insulation protective sleeve adhere to each other, which can cope with the installation of pipes of various sizes. In addition, during the installation of the thermal insulation protective sleeve, the elasticity of the non-slip particles makes the sleeve connection of the thermal insulation protective sleeve tighter and not easy to loosen, thereby effectively extending the service life of the thermal insulation protective sleeve. The high-temperature resistant heat-insulating layer can keep the heat emitted by the hot water pipe warm and prevent the heat from dissipating, thereby reducing the loss of hot water circulating inside the pipe, playing an energy-saving, environmental-friendly and practical role. Finally, the temperature-sensitive color-changing layer can sense the temperature of the hot water pipe surface and change its own color, which has a warning effect on the surrounding workers. The workers can understand the temperature changes of the hot water pipe by observing the raised blocks, which effectively improves the practicality and convenience and facilitates the use of the workers.

[0014] The utility model makes it more convenient for workers to install and remove the heat insulation protective cover through the adaptation of the Velcro sub-surface and the Velcro main surface. It can also cope with the installation of pipes of various sizes, greatly improving the adaptability and use range of the protective cover, facilitating the use of workers, and effectively improving practicality.
