Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic composite pipe devices, and in particular to a corrosion-resistant steel wire mesh reinforced plastic composite pipe. Background Technology
[0002] Corrosion-resistant steel wire mesh reinforced plastic composite pipes (commonly referred to as steel wire mesh composite pipes) are widely used in various fields due to their excellent performance. They are commonly used in urban water supply and drainage systems, as well as agricultural irrigation systems. They can effectively withstand internal and external pressure, preventing pipe deformation or rupture. They are also used in the transportation of oil, natural gas, and chemicals.
[0003] In existing technologies, some corrosion-resistant steel wire mesh reinforced plastic composite pipes combine a steel wire mesh skeleton and plastic materials to enhance the pipe's mechanical strength and pressure resistance. The inner and outer layers of plastic pipe provide corrosion resistance and chemical stability, while the middle steel wire mesh skeleton enhances the pipe's structural strength and pressure resistance. However, some corrosion-resistant steel wire mesh reinforced plastic composite pipes, without undergoing testing, transport different liquids without cleaning the inside of the pipe. This leads to chemical reactions between the different liquids, causing corrosion and damage to the pipe's interior, resulting in leaks and performance degradation. Utility Model Content
[0004] This utility model proposes a corrosion-resistant steel wire mesh reinforced plastic composite pipe, which aims to improve the problem that some existing corrosion-resistant steel wire mesh reinforced plastic composite pipes are inconvenient for liquid sampling and testing.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A corrosion-resistant steel wire mesh reinforced plastic composite pipe includes an outer pipe, a steel wire mesh fixedly connected to the inner wall of the outer pipe, an adhesive layer fixedly connected to the inner wall of the outer pipe, an inner pipe fixedly connected to the inner wall of the steel wire mesh, a connecting ring fixedly connected to one end of the outer pipe, a threaded post fixedly connected to the top outer wall of the connecting ring, an elastic component for providing elasticity to prevent liquid leakage in the pipe fitted on the inner wall of the threaded post, a pressure ring fixedly connected to the outside of the elastic component, a connecting rod fixedly connected to the bottom of the pressure ring, a blocking block fixedly connected to the bottom of the connecting rod, and a protective cap threadedly connected to the outside of the threaded post.
[0007] The outer and inner pipes are used to transport liquids. The wire mesh enhances the overall stability of the pipeline, reduces damage caused by external pressure, and thus extends the service life of the pipeline. The connecting ring connects the pipeline while preventing liquid leakage from its inner wall. The protective cover is used to protect the device inside. By pressing down the pressure ring, the connecting rod moves with the blocking block, allowing the liquid in the pipeline to be drawn out by the external pipeline, achieving the sampling effect.
[0008] As a further description of the above technical solution:
[0009] The elastic component includes a spring, one end of which is fixedly connected to a pressure rod, and the other end of which is fixedly connected to the inner wall of the threaded column.
[0010] The spring provides elasticity, keeping the blockage in a certain horizontal position to prevent liquid leakage from the pipe.
[0011] As a further description of the above technical solution:
[0012] The inner wall of the outer tube is fixedly connected with an anti-corrosion layer, and the inner wall of the outer tube is fixedly connected with a flame-retardant layer.
[0013] The anti-corrosion layer protects pipelines from the corrosive effects of chemicals and moisture in the underground environment. It extends the pipeline's lifespan, reduces the frequency of maintenance and replacement, and ensures the safe and stable operation of the pipeline system. The flame-retardant layer prevents the pipeline from contributing to combustion or rapidly spreading flames in the event of a fire. This layer helps improve the pipeline's safety under fire conditions, protecting both the pipeline and the surrounding environment.
[0014] As a further description of the above technical solution:
[0015] The inner wall of the inner tube is fixedly connected with a pressure-resistant layer, and the inner wall of the outer tube is fixedly connected with a waterproof layer.
[0016] The pressure-resistant layer is used to withstand the pressure from soil settlement, preventing pipe deformation or rupture, while also providing additional support. The waterproof layer is used to prevent groundwater or moisture from penetrating the inside of the pipe.
[0017] As a further description of the above technical solution:
[0018] The flame-retardant layer is made of fire-resistant and flame-retardant rock wool.
[0019] A commonly used flame-retardant material with excellent heat insulation and fire resistance properties.
[0020] As a further description of the above technical solution:
[0021] The anti-corrosion layer is made of corrosion-resistant polyethylene.
[0022] A thermoplastic material, resistant to chemical corrosion, suitable for external corrosion protection of pipes.
[0023] As a further description of the above technical solution:
[0024] The pressure-resistant layer is made of high-density polyethylene, which is resistant to pressure.
[0025] It is designed to provide good pressure resistance and durability.
[0026] As a further description of the above technical solution:
[0027] The waterproof layer is made of water-resistant polyurethane.
[0028] It has excellent waterproofing properties and is commonly used as a waterproofing layer for pipes.
[0029] This utility model has the following beneficial effects:
[0030] 1. In this utility model, the connecting ring is welded to the outer pipe to ensure that the pipe will not leak. At the same time, the protective cover is rotated off, the external pipe is connected, and the pressure ring is inserted. The blocking block is pressed down to allow the liquid in the pipe to be drawn out from the gap between the pressure ring and the blocking block, thereby achieving the effect of detecting the liquid in the pipe.
[0031] 2. In this utility model, the outer tube of the plastic composite pipe is provided with an anti-corrosion layer to protect the pipe from the corrosion of chemicals and moisture in the underground environment. At the same time, the outer layer is also provided with a flame-retardant layer to reduce the risk of fire and prevent the pipe from fueling the fire or spreading the flame rapidly in the event of a fire. These material layers protect the pipe while protecting the surrounding environment. Attached Figure Description

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.
[0041] Reference Figures 3 to 5 This utility model provides an embodiment of a corrosion-resistant steel wire mesh reinforced plastic composite pipe, comprising an outer pipe 1, the inner wall of which is provided with a material layer to protect the pipe; a steel wire mesh 2 is fixedly connected to the inner wall of the outer pipe 1 to increase the strength and durability of the pipe structure; an adhesive layer 12 is fixedly connected to the inner wall of the outer pipe 1 to fix the steel wire mesh 2, the outer pipe 1, and the inner pipe 3; an inner pipe 3 is fixedly connected to the inner wall of the steel wire mesh 2, the inner wall of which is provided with a material layer to prevent the penetration of liquid in the pipe and to resist pressure to protect the pipe; a connecting ring 4 is fixedly connected to one end of the outer pipe 1 to connect the pipe and prevent the liquid in the pipe from leaking out; a threaded post is fixedly connected to the top outer wall of the connecting ring 4. 5. A spring 7 is fitted inside the threaded post 5 to provide elasticity and prevent liquid leakage from the pipeline. The elasticity keeps the pressure rod 6 and the connected device in a certain position. One end of the spring 7 is fixedly connected to the pressure rod 6 to support part of the device. A pressure ring 8 is fixedly connected to the outside of the pressure rod 6 and is connected to the pipe joint. The pressure ring 8 is moved downwards. A connecting rod 9 is fixedly connected to the bottom of the pressure ring 8 to connect to the plug 10. The gap of the ring 8 allows liquid to be drawn out. A plug 10 is fixedly connected to the bottom of the connecting rod 9 to plug the threaded post 5 to prevent liquid from leaking out. A protective cover 11 is threadedly connected to the outside of the threaded post 5 to protect the device inside.
[0042] Reference Figure 1 , Figure 2 The inner wall of the outer pipe 1 is fixedly connected with an anti-corrosion layer 16, which is made of anti-corrosion polyethylene, to protect the pipe from the corrosion of chemicals and moisture in the underground environment. The inner wall of the outer pipe 1 is fixedly connected with a flame-retardant layer 15, which is made of fireproof and flame-retardant rock wool, to prevent the pipe from fueling combustion or rapidly spreading flames in the event of a fire.
[0043] Reference Figure 2The inner wall of the inner pipe 3 is fixedly connected with a pressure-resistant layer 13, which is made of high-density polyethylene that resists pressure, and is used to enhance the pressure resistance of the pipe in the underground environment. The inner wall of the outer pipe 1 is fixedly connected with a waterproof layer 14, which is made of water-resistant polyurethane, and is used to prevent liquid from seeping out of the inner wall of the pipe.
[0044] Compared with some existing devices, the above-described method involves welding the connecting ring 4 to the outer pipe 1 to prevent pipe leakage. Simultaneously, the protective cover 11 is rotated and removed, connected to an external pipe, inserted into the pressure ring 8, and the blocking block 10 is pressed down to allow liquid in the pipe to be drawn out through the gap between the pressure ring 8 and the blocking block 10, thus solving the problem of not being able to detect liquid inside the pipe. The outer pipe 1 of the plastic composite pipe is equipped with an anti-corrosion layer 16 to protect it from corrosion by chemicals and moisture in the underground environment. It also has a flame-retardant layer 15 to reduce fire risk and prevent the pipe from contributing to combustion or rapidly spreading flames in the event of a fire, thus solving the problems of pipe damage from chemicals and pipe combustion in the event of a fire.
[0045] Working principle: One end of the two outer tubes 1 is fixed with the connecting ring 4 to prevent leakage of liquid flowing from the inner wall. The protective cover 11 is unscrewed from the threaded post 5, and the external pipe is inserted into the pressure ring 8. The connecting rod 9 slides in the threaded post 5, and at the same time, the connecting rod 9 moves the plug 10 downward, allowing the liquid in the pipe to be drawn out from the gap between the pressure ring 8 and the plug 10, so as to facilitate the detection of the liquid in the pipe. The spring 7 connected to the pressure rod 6 provides elasticity, allowing the plug 10 to bounce back to the inner wall of the threaded post 5 to prevent liquid from leaking from the threaded post 5.
[0046] The pipeline has two layers: an outer pipe 1 and an inner pipe 3, connected by a wire mesh 2 and an adhesive layer 12 to increase the strength and durability of the pipeline structure. The inner wall of the outer pipe 1 is equipped with an anti-corrosion layer 16 to protect the pipeline from the corrosion of chemicals and moisture in the underground environment, and also has a flame-retardant layer 15 to prevent the pipeline from contributing to combustion or rapidly spreading flames in the event of a fire. The inner pipe 3 is equipped with a pressure-resistant layer 13 and a waterproof layer 14. The pressure-resistant layer 13 enhances the pipeline's compressive strength in the underground environment, resisting pressure from the soil, while the waterproof layer 14 prevents liquid from seeping out of the inner wall of the pipeline.
[0047] 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.
