Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipelines, specifically, it relates to a corrosion-resistant PTFE-based composite material pipe. Background Technology
[0002] Composite pipes are formed by combining metal pipes and thermoplastic plastics as a base, or by welding non-metallic materials such as polyethylene or cross-linked polyethylene inside and outside. They have the advantages of both metal pipes and non-metallic pipes.
[0003] Literature review revealed that most existing composite material pipes are typically manufactured using a single-piece molding process. While these pipes offer good corrosion resistance, their continuous nature makes them susceptible to cracking under pressure during transport due to the lack of proper support, thus impacting their lifespan. Furthermore, the pipe connection process is cumbersome, requiring two workers to connect the two pipe sections before another worker connects them into a single sleeve, which is quite inconvenient. Therefore, this utility model is proposed to address these issues. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a corrosion-resistant PTFE-based composite material pipe.
[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0006] A corrosion-resistant PTFE-based composite material pipe includes a first pipe, a second pipe, a positioning block, a connecting cover, and a wear-resistant ring. One end of the first pipe and the second pipe are provided with a plug-in end. The other end of the first pipe and the second pipe are provided with a plug-in groove for the plug-in end to be inserted. Positioning blocks are fixed at both the upper and lower ends of the plug-in end. The upper and lower ends of the plug-in groove are provided with irregular grooves for the positioning blocks to be inserted.
[0007] Both the first and second pipes are fixedly fitted with external reinforcing rings, and wear-resistant rings are fixedly bonded to the outer surface of the external reinforcing rings. The wear-resistant rings are made of polyurethane.
[0008] The first pipe and the second pipe are both provided with threads for threaded connection of the connecting cover on their outer front sides. The connecting cover is provided with a clearance hole in the middle that is adapted to the outer dimensions of the first pipe and the second pipe. The first pipe and the second pipe are both fixedly fitted with a limiting ring that abuts against the inner side of the connecting cover on their outer rear sides.
[0009] A first sealing ring is fixedly installed on the outside of the plug-in end.
[0010] Optionally, a second sealing ring is provided on the inner side of the connecting cover, and a third sealing ring is fixed on the contact surface between the connecting cover and the wear-resistant ring. The second sealing ring, the third sealing ring, and the first sealing ring are all made of corrosion-resistant material.
[0011] Optionally, a buffer pad is fixed to the other end of both the first pipe and the second pipe. The buffer pad itself is made of rubber, and an annular groove for inserting the buffer pad is opened at one end of both the first pipe and the second pipe.
[0012] Optionally, the outer surface of the connecting cover is coated with a first capsaicin layer.
[0013] Optionally, both the first and second pipes include an inner base pipe, an outer base pipe, an inner support ring, an inner corrosion-resistant layer, and an outer corrosion-resistant layer. The outer base pipe is sleeved on the outside of the inner base pipe. Multiple inner support rings are provided between the inner base pipe and the outer base pipe. The gap between the inner ring and the inner and outer base pipes is filled with an inter-bonding layer. The inner wall of the inner base pipe is fixed with an inner corrosion-resistant layer, and the outer side of the outer base pipe is provided with an outer corrosion-resistant layer.

[0015] Optionally, the outer surface of the outer corrosion-resistant layer is coated with a second capsaicin layer.
[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:
[0017] This utility model patent improves the pressure resistance of the pipeline itself by setting an outer reinforcing ring and an inner support ring. In order to prevent the first and second capsaicin layers on the surface of the pipeline and the connecting cover from being scratched due to friction during transportation, and to save manpower and facilitate the docking and installation of the device, the first and second pipelines can be docked with the plug end and the plug groove, and then the positioning block is inserted into the irregular groove to complete the temporary positioning. At this time, no multiple workers are required to support it. Then, the connecting cover on the outside of the first pipeline is rotated to connect the threaded connection on the outside of the second pipeline to complete the splicing. The installation is simple and convenient.

Detailed Implementation
[0029] The present invention will now be described in further detail with reference to the accompanying drawings.
[0030] Please see Figures 1 to 6 This utility model provides a technical solution: a corrosion-resistant PTFE-based composite material pipe, including a first pipe 1, a second pipe 2, a positioning block 5, a connecting cover 9 and a wear-resistant ring 8. One end of the first pipe 1 and the second pipe 2 are provided with a plug end 3. The other end of the first pipe 1 and the second pipe 2 are provided with a plug groove 4 for the plug end 3 to be plugged in. The upper and lower ends of the plug end 3 are fixed with positioning blocks 5. The upper and lower ends of the plug groove 4 are provided with irregular grooves 6 for the positioning blocks 5 to be plugged in.
[0031] Both the first pipe 1 and the second pipe 2 are fixedly fitted with an outer reinforcing ring 7. A wear-resistant ring 8 is fixedly bonded to the outer surface of the outer reinforcing ring 7. The wear-resistant ring 8 itself is made of polyurethane.
[0032] The front outer sides of the first pipe 1 and the second pipe 2 are provided with threads 10 for threaded connection of the connecting cover 9. The middle part of the connecting cover 9 is provided with a clearance hole that matches the outer dimensions of the first pipe 1 and the second pipe 2. The rear outer sides of the first pipe 1 and the second pipe 2 are fixedly fitted with a limiting ring 11 that abuts against the inner side of the connecting cover 9.
[0033] The plug end 3 is externally fixed with a first sealing ring 12. Considering that the pipe is a through pipe, it is prone to pressure rupture during transportation due to the lack of good support, which will affect the service life of the pipe. Secondly, the pipe connection process is relatively troublesome, requiring two workers to connect the two pipe sections and then another worker to connect the two pipe sections into the same sleeve, which is quite troublesome. This utility model patent improves the pressure resistance of the pipe itself by setting an outer reinforcing ring 7 and an inner support ring 19. In order to prevent the first capsaicin layer 16 and the second capsaicin layer 23 on the surface of the pipe and the connecting cover 9 from being scratched due to friction during transportation, and to save manpower and facilitate the connection and installation of the device, the first pipe 1 and the second pipe 2 can be connected by plug end 3 and plug groove 4, and then the positioning block 5 and the irregular groove 6 can be plugged to complete the temporary positioning. At this time, no multiple workers are needed to support it. Then, the connecting cover 9 on the outside of the first pipe 1 and the thread 10 on the outside of the second pipe 2 can be rotated to complete the splicing. The installation is simple and convenient.
[0034] The inner side of the connecting cover 9 is provided with a second sealing ring 13, and a third sealing ring 14 is fixed on the contact surface between the connecting cover 9 and the wear-resistant ring 8. The second sealing ring 13, the third sealing ring 14 and the first sealing ring 12 are all made of corrosion-resistant material. The second sealing ring 13 fills the gap between the relief hole of the connecting cover 9 and the first pipe 1 and the second pipe 2 to prevent leakage. The third sealing ring 14 seals the contact surface between the connecting cover 9 and the wear-resistant ring 8 to prevent external liquid from seeping into the pipe.
[0035] The other end of the first pipe 1 and the second pipe 2 is fixed with a buffer pad 15. The buffer pad 15 is made of rubber. One end of the first pipe 1 and the second pipe 2 is provided with an annular groove for the buffer pad 15 to be inserted. The buffer pad 15 and the contact surface between the first pipe 1 and the second pipe 2 play a buffering role, preventing excessive force during docking from causing the contact surface of the first pipe 1 and the second pipe 2 to impact and cause damage.
[0036] The outer surface of the connecting cover 9 is coated with a first capsaicin layer 16. The first capsaicin layer 16 protects the connecting cover 9 and prevents small animals from biting the connecting cover 9 after the device is laid.
[0037] The first pipe 1 and the second pipe 2 both include an inner base pipe 17, an outer base pipe 18, an inner support ring 19, an inner corrosion-resistant layer 20, and an outer corrosion-resistant layer 21. The outer base pipe 18 is sleeved on the outside of the inner base pipe 17. Multiple inner support rings 19 are provided between the inner base pipe 17 and the outer base pipe 18. The gaps between the inner rings and the inner base pipe 17 and the outer base pipe 18 are filled with an adhesive layer. The inner wall of the inner base pipe 17 is fixed with the inner corrosion-resistant layer 20, and the outer side of the outer base pipe 18 is provided with the outer corrosion-resistant layer 21. The inner support rings 19 reinforce the inner base pipe 17 and the outer base pipe 18. Furthermore, the presence of the inner corrosion-resistant layer 20 and the outer corrosion-resistant layer 21 gives both the inner and outer surfaces of the pipe corrosion-resistant properties, thus improving the service life of the device.
[0038] Among them, a metal reinforcing mesh 22 is fixed to the outside of the outer base pipe 18. The outer surface of the metal reinforcing mesh 22 is fixed to the inner surface of the outer corrosion-resistant layer 21. The use strength of the pipeline is further enhanced by setting the metal reinforcing mesh 22.
[0039] The outer surface of the outer corrosion-resistant layer 21 is coated with a second capsaicin layer 23. The second capsaicin layer 23 acts as a bite-proof layer on the pipe surface, preventing small animals from chewing the pipe.
[0040] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
