Description

Technical Field

[0001] This utility model relates to the field of PTFE tube technology, specifically to a new composite material wear-resistant PTFE tube. Background Technology

[0002] PTFE tubing, also known as polytetrafluoroethylene tubing, is a composite tubular material made from polytetrafluoroethylene resin through a plunger extrusion process. This tubing is a tight bond between steel and plastic pipes, possessing properties such as non-absorption of water and resistance to strong acids, alkalis, and chemical reagents. It is primarily used for conveying high-temperature, highly corrosive gases or liquids. Due to its excellent chemical stability and low coefficient of friction, PTFE tubing is commonly used to manufacture wire insulation sheaths, corrosive fluid pipelines, and high-frequency electrical insulation parts. Bearings made from PTFE tubing exhibit self-lubricating properties, ensuring smooth operation during mechanical start-up and shutdown.

[0003] While traditional PTFE tubing has a certain degree of corrosion resistance, it is significantly lacking in wear resistance, tensile strength, and high-temperature resistance. When conveying fluids containing solid particles or in high-temperature and high-stress environments, traditional PTFE tubing is prone to wear or rupture, leading to fluid leakage, affecting production efficiency, and causing safety hazards and environmental pollution. Utility Model Content

[0004] This invention provides a new composite material wear-resistant PTFE pipe. By combining a liner, a reinforcing layer, and a protective layer, the advantages of each material are fully utilized. The liner, made of carbon nanotube-modified PTFE composite material, improves the pipe's wear resistance. The reinforcing layer, woven from aramid fibers, enhances the pipe's tensile strength and elongation at break. The protective layer, made of nano-silica-filled PTFE material, improves the pipe's high-temperature resistance. The various structures work together to make the PTFE pipe perform excellently in terms of wear resistance, tensile strength, and high-temperature resistance. The protective tube provides additional protection for the PTFE pipe body, further reducing wear from external factors and extending the overall service life of the pipe. At the same time, the guide mechanism and installation mechanism work together to enhance the stability of the connection between the protective tube and the PTFE pipe body, preventing separation of the protective tube from the PTFE pipe body.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a new composite material wear-resistant PTFE tube, comprising:

[0025] PTFE tube body 1;

[0026] Protective tube 2 is movably sleeved on the outer wall of the wear-resistant PTFE tube body 1;

[0027] The guide mechanism 3 is provided in multiple sets, and each set of guide mechanism 3 is equidistantly arranged in the protective tube 2 along the circumferential direction;

[0028] The mounting mechanism 4 is provided in two sets, with each set of mounting mechanism 4 symmetrically located at both ends of the wear-resistant PTFE tube body 1.

[0029] In this implementation plan: the protective tube 2 is made of wear-resistant ceramic, which has extremely high hardness and wear resistance, and can provide additional protection for the PTFE tube body 1, further reducing the wear of the PTFE tube body 1 by external factors and extending the overall service life of the pipeline. The guide mechanism 3 guides the installation of the protective tube 2 and the PTFE tube body 1. The installation mechanism 4 is used to install and fix the PTFE tube body 1 and the protective tube 2 together.

[0030] Specifically, the PTFE tube body 1 includes a liner 101, a reinforcing layer 102, and a protective layer 103. The reinforcing layer 102 is fixedly sleeved on the outer wall of the liner 101, and the protective layer 103 is sleeved on the outer wall of the reinforcing layer 102.

[0031] In this embodiment: the liner 101 is made of carbon nanotube-modified PTFE composite material. Carbon nanotubes have extremely high strength and modulus. Introducing them into PTFE to form a composite material can significantly improve the wear resistance of PTFE. PTFE itself has excellent corrosion resistance and self-lubricating properties. After being combined with carbon nanotubes, the wear resistance of the material is greatly improved while maintaining these excellent properties, enabling the liner 101 to better cope with the scouring of fluids containing solid particles. The reinforcing layer 102 is woven from aramid fibers. Aramid fibers can improve the tensile strength of the tube body and increase the elongation at break. The aramid fibers are arranged in a cross direction with the pipe axis of the liner 101, which allows the reinforcing layer 102 to be uniformly stressed in all directions, effectively improving the tensile strength of the pipe and increasing the elongation at break. This makes the pipe less prone to breakage when subjected to large external forces, improving the reliability and safety of the pipe. The protective layer 103 is filled with nano-silica PTFE material. Nano-silica filled PTFE material has good high temperature resistance and chemical stability, which can effectively block external factors from damaging the inside of the pipe, allowing the pipe to work normally in high temperature environments and expanding the application range of the pipe.

[0032] Specifically, each guide mechanism 3 includes a guide rod 301 and a guide groove 302. The guide rod 301 is fixedly installed on the inner wall of the protective tube 2, and the guide groove 302 is opened on the outer wall of the PTFE tube body 1. The guide rod 301 and the guide groove 302 are in sliding fit.

[0033] In this embodiment: the sliding fit between the guide rod 301 and the guide groove 302 can guide the relative movement between the protective tube 2 and the PTFE tube body 1, ensuring that the protective tube 2 can be stably fitted outside the PTFE tube body 1, and preventing misalignment or jamming between the protective tube 2 and the PTFE tube body 1 when the pipeline is subjected to external force, thus ensuring the normal operation of the pipeline.

[0034] Specifically, each set of installation mechanisms 4 includes a connecting ring 401, multiple sets of positioning components and multiple sets of fixing components. The connecting ring 401 is located on multiple sets of positioning components, each set of positioning components is located on the connecting ring 401, and each set of fixing components is located on the connecting ring 401.

[0035] In this embodiment: the protective tube 2 and the PTFE tube body 1 can be connected together by the positioning component on the connecting ring 401, and the connecting ring 401 can be fixed on the protective tube 2 by the fixing component.

[0036] Specifically, each positioning component includes a first positioning groove 402, a second positioning groove 403, and two positioning rods 404. The first positioning groove 402 is opened on one side of the outer wall of the PTFE tube body 1, and the second positioning groove 403 is opened on one side of the outer wall of the protective tube 2. Each positioning rod 404 is slidably embedded in the inner wall of the first positioning groove 402 and the second positioning groove 403, and each positioning rod 404 is fixedly set on one side of the outer wall of the connecting ring 401.

[0037] In this embodiment, the positioning rod 404 on the connecting ring 401 enters the first positioning groove 402 and the second positioning groove 403 respectively, which can accurately position the protective tube 2 and the PTFE tube body 1, ensuring that the relative position between the two is accurate and providing convenience for subsequent fixing operations.

[0038] Specifically, each set of fixing components includes a threaded groove 405 and a screw 406. The threaded groove 405 is opened on one side of the outer wall of the protective tube 2, and the screw 406 is bolted to one side of the outer wall of the connecting ring 401, and the screw 406 is threaded to the inner wall of the threaded groove 405.

[0039] In this embodiment, the threaded engagement between the screw 406 and the threaded groove 405 secures the protective tube 2 and the PTFE tube body 1 together, preventing the protective tube 2 from separating from the PTFE tube body 1 during use and ensuring the overall structural stability of the pipeline.

[0040] In use, the liner 101, reinforcing layer 102, and protective layer 103 are combined to fully utilize the advantages of each material. The liner 101, made of carbon nanotube-modified PTFE composite material, improves the pipe's wear resistance; the reinforcing layer 102, woven from aramid fibers, enhances the pipe's tensile strength and elongation at break; and the protective layer 103, made of nano-silica-filled PTFE material, improves the pipe's high-temperature resistance. The coordinated structure results in excellent performance in terms of wear resistance, tensile strength, and high-temperature resistance, meeting the fluid transport requirements under complex working conditions. Furthermore, the protective pipe 2 provides additional protection for the PTFE pipe body 1. To reduce wear on the PTFE tube body 1 from external factors and extend the overall service life of the pipeline, when installing the protective tube 2, first, put the protective tube 2 on the outer wall of the PTFE tube body 1, so that the guide rod 301 and the guide groove 302 are properly matched to achieve relative sliding between the protective tube 2 and the PTFE tube body 1. Place the connecting ring 401 in a suitable position so that the positioning rod 404 is embedded in the first positioning groove 402 and the second positioning groove 403 respectively to achieve accurate positioning of the protective tube 2 and the PTFE tube body 1. Then, pass the screw 406 through the connecting ring 401 and screw it into the threaded groove 405. The protective tube 2 and the PTFE tube body 1 are firmly fixed together by bolt connection.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
