Description

Technical Field

[0001] This utility model relates to the field of pipe technology, and in particular to a cold-resistant reinforcement layer for pipes. Background Technology

[0002] Pipes are materials used to make pipe fittings. Their types and properties directly affect the quality and application range of pipe fittings. Pipes are an indispensable basic material in construction projects, industrial facilities and daily life. They are mainly used to transport fluids (such as water, gas, oil, etc.), protect cables or serve as structural supports. Pipes are hollow cross-section materials made of metal, plastic or composite materials, used to make piping systems or other pipe fittings. Different pipe materials have different properties such as strength, corrosion resistance, and temperature resistance. For example, stainless steel pipes have strong corrosion resistance, while PVC pipes are lightweight and low in cost.

[0003] The existing technical solutions mentioned above have the following drawbacks: the existing pipes lack a cold-resistant protective structure, making them prone to breakage in cold environments, which affects their use. Utility Model Content

[0004] The purpose of this invention is to provide a cold-resistant reinforcing layer for pipes.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The cold-resistant reinforcement layer of the pipe includes an inner pipe body, the outer side of which is wrapped with a braided layer, a metal coil is installed on the outer side of the braided layer, a polyurethane insulation layer is wrapped on the outer side of the braided layer, a rubber layer is wrapped on the outer side of the polyurethane insulation layer, and the interior of the braided layer includes a first nylon wire and a second nylon wire.

[0007] By adopting the above technical solution, a cold-resistant and heat-insulating material layer is added to the outside of the inner tube, and a structurally reinforced protective layer is added at the same time. This can provide structural strength to the pipe while ensuring cold resistance, and prevent the pipe from breaking easily.

[0008] Furthermore, the metal coil is spirally wound around the outside of the braided layer.

[0009] By adopting the above technical solution, the metal coil ensures the structural strength of the pipe's interior and prevents it from breaking due to strength.

[0010] Furthermore, multiple sets of the first nylon thread and the second nylon thread are provided, and the first nylon thread and the second nylon thread in each set are interwoven and woven together.

[0011] By adopting the above technical solution, a braided layer made of multiple sets of nylon threads can be used to wrap the outer side of the inner tube, and with the help of metal coils, the strength of the tube can be further improved.

[0012] Furthermore, the polyurethane insulation layer is placed between the polyurethane insulation layer and the metal coil.

[0013] By adopting the above technical solutions and adding an insulation layer, the insulation effect can be improved.

[0014] In summary, the beneficial technical effects of this utility model are as follows:

[0015] The tube incorporates a braided layer, a polyurethane insulation layer, a rubber layer, metal coils, and nylon wire. The braided layer and metal coils inside the tube can be wound and fixed to ensure the internal structural strength. At the same time, the polyurethane insulation layer and rubber layer add a heat-insulating and cold-resistant structure to the outside, providing protection from the outside and creating a cold-resistant protection effect.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Reference Figure 1-3 The pipe's cold-resistant reinforcement layer includes an inner pipe body 1, a braided layer 2 wrapped around the outside of the inner pipe body 1, a metal coil 5 installed on the outside of the braided layer 2, a polyurethane insulation layer 3 wrapped around the outside of the braided layer 2, and a rubber layer 4 wrapped around the outside of the polyurethane insulation layer 3. The braided layer 2 contains a first nylon thread 21 and a second nylon thread 22. By adding a cold-resistant and heat-insulating material layer to the outside of the inner pipe body 1, and simultaneously adding a structurally reinforced protective layer, the pipe's structural strength can be provided while ensuring cold resistance, preventing the pipe from easily breaking. The metal coil 5 ensures the internal structural strength of the pipe and prevents it from breaking due to excessive strength. The braided layer 2, formed by multiple sets of nylon threads interwoven together, can wrap the outside of the inner pipe body 1, and together with the metal coil 5, can further improve the strength of the pipe.

[0022] like Figure 1-3As shown, the metal coil 5 is spirally wound on the outside of the braided layer 2. Multiple sets of the first nylon wire 21 and the second nylon wire 22 are provided. Each set of the first nylon wire 21 and the second nylon wire 22 are interwoven with each other. The polyurethane insulation layer 3 is placed between the polyurethane insulation layer 3 and the metal coil 5.

[0023] The implementation principle of this embodiment is as follows: the outer side of the inner tube 1 has a braided layer 2 and a metal coil 5. The braided layer 2 can be interwoven to improve the protection of the outer side of the inner tube 1. At the same time, the metal coil 5 wound on the outer side can improve the structural strength of the tube. In addition, the polyurethane insulation layer 3 is added to the outer side to improve the heat preservation and cold resistance. The rubber layer 4 protects the outer side of the tube, so that the tube has a certain cold resistance, the structure will not break easily, the strength is sufficient, and the practicality is higher.

[0024] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
