Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite pipes, and in particular to a double-layer plastic composite pipe with a steel wire mesh skeleton. Background Technology
[0002] Steel wire mesh reinforced double-layer plastic composite pipe is a new type of composite pipe. Due to the reinforcing effect of the steel wire mesh skeleton, the composite pipe has high strength and can withstand greater pressure and tension. Compared with traditional plastic pipes, its pressure-bearing capacity can be increased several times or even more.
[0003] In existing technologies, some pipes are connected by electrofusion at the joint. However, the connection is not precise enough during the electrofusion process, which greatly reduces the sealing effect and causes leakage at the joint. This not only wastes resources but also pollutes the surrounding environment. A double-layer plastic composite pipe with steel wire mesh skeleton is proposed. Utility Model Content

[0011] As a further description of the above technical solution:
[0012] The outer tube is fixedly connected to a heat-resistant layer, and the heat-resistant layer is fixedly connected to a reinforcing layer.

The heat-resistant layer enhances the high-temperature resistance of the composite tube, allowing it to adapt to high-temperature environments. The reinforcing layer strengthens the overall structure and prevents damage from external forces.
[0014] As a further description of the above technical solution:
[0015] An antibacterial layer is fixedly connected inside the inner tube, and an oxygen barrier layer is fixedly connected outside the antibacterial layer.
[0016] The inner tube is equipped with an antibacterial layer and an oxygen barrier layer. The antibacterial layer inhibits bacterial growth, ensuring the hygiene of the transported medium. The oxygen barrier layer prevents oxygen penetration, protecting the quality of the medium.
[0017] As a further description of the above technical solution:
[0018] The heat-resistant layer is made of carbon fiber, and the reinforcing layer is made of glass fiber.
[0019] The heat-resistant layer is made of carbon fiber, which has excellent high-temperature resistance. The reinforcing layer is made of glass fiber to enhance the strength of the pipe.

[0021] The antibacterial layer is made of an inorganic antibacterial agent, and the oxygen barrier layer is made of an oxygen barrier agent.
[0022] The antibacterial layer is made of inorganic antibacterial agents, effectively preventing bacteria. The oxygen barrier layer uses oxygen barrier agents to prevent oxygen penetration.
[0023] As a further description of the above technical solution:
[0024] An adhesive layer is fixedly connected to the outside of the outer tube, and the material of the adhesive layer is epoxy resin.
[0025] The outer tube has an adhesive layer made of epoxy resin. This enhances connectivity, making the composite pipe bond more firmly to other components. It also improves sealing and prevents leakage.
[0026] As a further description of the above technical solution:
[0027] The inner part of the connecting frame is slidably connected to the outside of the limiting post, and the outer part of the connecting frame is slidably connected to the inside of the connecting plate.
[0028] This sliding connection method can precisely limit the movement trajectory of the connecting frame and prevent it from deviating.
[0029] This utility model has the following beneficial effects:
[0030] 1. In this utility model, by placing two connecting rings on the connection points of the two outer pipes respectively, tying the connecting rope to the fixing ring, and then holding the connecting frame, passing it through one of the connecting rings from below, and then passing it through the connecting ring from above, the connecting rope passes through both connecting rings, thus achieving the effect of precisely connecting the two pipes that need to be electrofused.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] Reference Figure 1 , Figure 2This utility model provides an embodiment of a double-layer plastic composite pipe with a steel wire mesh skeleton, comprising an outer pipe 1, with a steel mesh frame 2 fixedly connected inside the outer pipe 1. The steel mesh frame 2 is woven from high-strength steel wire, presenting a mesh structure. The steel wire is usually made of high-quality carbon steel or alloy steel, and after special processing, it has extremely high strength and toughness. An inner pipe 3 is fixedly connected to the outside of the steel mesh frame 2. The inner pipe 3 is also cylindrical and is made of sanitary-grade polyethylene plastic, which has good corrosion resistance and chemical stability, and can ensure that the transported medium is not contaminated. A connecting ring 4 is sleeved on the outside of the outer pipe 1. The connecting ring 4 is usually a ring-shaped metal structure, made of high-strength alloy, with a regular shape, smooth surface, and a certain thickness and width. A connecting rope 5 is sleeved on the outside of the connecting ring 4. The connecting rope 5 is generally made of high-strength fiber material, which is usually relatively soft but has high tensile strength. A fixing ring 6 is fixedly connected to the outside of the connecting rope 5.
[0040] The top of the fixed ring 6 is fixedly connected to a limiting component that provides limiting force. The limiting component includes a connecting plate 7, which is usually a rectangular metal plate made of high-strength alloy. The bottom of the connecting plate 7 is fixedly connected to the top of the fixed ring 6. Two limiting posts 8 are fixedly connected to the outside of the connecting plate 7. The limiting posts 8 are generally cylindrical metal structures with certain strength and rigidity. The outside of the limiting component is slidably connected to a connecting frame 9. The shape and size of the connecting frame 9 are determined according to the connection requirements of the composite pipe. It generally has certain strength and stability. The inside of the connecting frame 9 is slidably connected to the outside of the limiting posts 8, and the outside of the connecting frame 9 is slidably connected to the inside of the connecting plate 7.
[0041] Reference Figure 3 , Figure 4 The outer tube 1 is fixedly connected to a heat-resistant layer 11, which is usually in the form of a thin sheet and evenly covers the outer surface of the outer tube 1. The heat-resistant layer 11 is fixedly connected to a reinforcing layer 10. The heat-resistant layer 11 is made of carbon fiber, which has extremely high heat resistance and can withstand high temperature environments without deformation or damage. The reinforcing layer 10 is made of glass fiber, which has high strength and high toughness and can provide additional reinforcement for the composite tube. The inner tube 3 is fixedly connected to an antibacterial layer 13. The antibacterial layer 13 is fixedly connected to an oxygen barrier layer 14. The antibacterial layer 13 is made of an inorganic antibacterial agent, which can effectively inhibit the growth of bacteria and microorganisms and ensure that the transported medium is not contaminated. The oxygen barrier layer 14 is made of an oxygen barrier agent, which has good chemical stability and weather resistance and can maintain its oxygen barrier performance under various environmental conditions. The outer tube 1 is fixedly connected to an adhesive layer 12, which is made of epoxy resin, which has good bonding properties and can firmly bond the outer tube 1 to other components.
[0042] Working principle: First, place the two connecting rings 4 on the connection points of the two outer pipes 1 respectively, and tie the connecting rope 5 to the fixing ring 6. Then, hold the connecting frame 9 and pass it through one of the connecting rings 4 through the limiting post 8 below the connecting plate 7. Then, pass it through the connecting ring 4 through the limiting post 8 above the connecting plate 7, so that the connecting ring 4 passes through the inside of the connecting frame 9 and out. Thus, the connecting rope 5 on the fixing ring 6 passes through the two connecting rings 4, moving the two pipes with connecting rings together to make the two pipes accurately fixed. Then, use the electrofusion device to make a precise electrofusion connection at the pipe connection point.
[0043] Then, the outer pipe 1 has a reinforcing layer 10 made of glass fiber, which increases the strength and rigidity of the outer pipe 1 while reducing the weight of the pipe. Glass fiber also enhances the heat resistance and dimensional stability of the pipe. There is also a heat-resistant layer 11 made of carbon fiber, which increases the heat resistance and dimensional stability of the inner pipe 3. Carbon fiber also has good corrosion resistance and fatigue resistance. There is also an antibacterial layer 13 made of inorganic antibacterial agent, which effectively inhibits the growth of bacteria and microorganisms in the pipe, prevents the pipe from being contaminated, and ensures the hygiene and safety of the transported medium. There is also an oxygen barrier layer 14 made of oxygen barrier agent, which has good chemical stability and weather resistance, effectively preventing oxygen penetration and preventing the transported medium from being oxidized and deteriorated, thus improving the overall performance of the double-layer composite pipe.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
