Description

Technical Field

[0001] This utility model relates to the field of cast rubber pipe technology, specifically to an aging-resistant tetrahydrofuran cast rubber pipe. Background Technology

[0002] Cast rubber hoses are tubular products typically made by casting rubber materials using a specific process. They are generally made of natural or synthetic rubber and their shape and dimensions can be precisely controlled through mold casting. Cast rubber hoses possess excellent flexibility, corrosion resistance, wear resistance, and sealing performance. In the industrial field, they are commonly used to transport various fluids, such as chemical raw materials, water, and oil; in some mechanical devices, they can serve as shock absorbers and buffers, protecting equipment; and in daily life, some cast rubber hoses are also used in household products, providing convenience for people's lives.

[0003] Tetrahydrofuran (THF), an important organic synthetic raw material, is a commonly used material in the production of cast rubber pipes. Cast rubber pipes made from THF exhibit excellent chemical stability, resisting the corrosive effects of various chemical reagents, and demonstrate good mechanical properties under normal conditions. However, in practical applications, THF cast rubber pipes still have significant shortcomings. Due to their inherent structural characteristics, they are prone to aging during long-term use. Especially in damp environments, the penetration and corrosive effects of water molecules accelerate the aging process, causing the rubber material to gradually harden and become brittle, leading to cracking and breakage. This not only reduces the service life of the cast rubber pipes but may also cause safety hazards such as media leakage. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes an anti-aging tetrahydrofuran cast rubber pipe that has good anti-aging effect, is easy to use in humid environments, and has good safety performance.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is as follows: an aging-resistant tetrahydrofuran cast rubber pipe, comprising: a pipe body cast from tetrahydrofuran material, the pipe body comprising an inner pipe layer and an outer pipe layer, a reinforcing layer provided between the inner pipe layer and the outer pipe layer; and an aging-resistant coating applied to the outer surface of the outer pipe layer.

[0006] The outer side of the tube is connected to a spiral protective alloy component, which has a hollow layer inside.

[0007] Furthermore, the reinforcing layer is a fiber woven mesh, which is made of interwoven polyester fibers and glass fibers.

[0008] Furthermore, the aging-resistant coating is a nano-titanium dioxide composite coating, which is uniformly coated on the outer surface of the outer tube layer by a spraying process.

[0009] Furthermore, the inner surface of the inner tube layer is provided with an anti-corrosion layer, which is a polytetrafluoroethylene coating.

[0010] Furthermore, the tube body is provided with connecting parts at both ends, with an internal thread on the inner wall of one connecting part and a matching external thread on the outer wall of the other connecting part.

[0011] Furthermore, the connecting part is integrally formed with the tube body, and the material of the connecting part is the same as that of the tube body.

[0012] Furthermore, the protective alloy component is narrower near the tube body and wider away from the tube body.

[0013] The advantages of this utility model compared with the prior art are:

[0014] This tetrahydrofuran cast rubber pipe exhibits excellent anti-aging properties in humid environments. The nano-titanium dioxide composite anti-aging coating applied to the outer pipe surface effectively absorbs and scatters ultraviolet rays, resisting the penetration and erosion of water molecules in humid environments, significantly slowing down the aging process and preventing problems such as hardening and cracking due to aging. At the same time, the reinforcing layer uses a fiber woven mesh of polyester fiber and glass fiber to enhance the overall strength and toughness of the pipe, enabling it to maintain structural stability in humid environments and resist performance degradation due to aging.

[0015] The spiral-shaped protective alloy components not only provide mechanical protection for the pipe body, but their unique hollow layer design also acts as a buffer and heat insulation in humid environments, reducing the impact of the external environment on the pipe body. Furthermore, the PTFE anti-corrosion layer on the inner surface of the inner pipe layer prevents the erosion of the transported medium. Working in conjunction with the aging-resistant coating, this further extends the service life of the cast rubber pipe in humid environments, ensuring its stable and reliable operation.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] Combined with appendix Figure 1 To be continued Figure 4 The reinforcing layer 3 between the inner tube layer 1 and the outer tube layer 2 enhances the overall strength and pressure resistance of the pipe, making the cast rubber pipe less prone to deformation and breakage during use. The aging-resistant coating 4 on the outer surface of the outer tube layer 2 effectively resists the erosion of the pipe by external environmental factors and slows down the aging process. The spiral-shaped protective alloy component 5 with a hollow layer not only provides additional mechanical protection for the pipe and reduces collision damage, but also utilizes the hollow layer to provide a certain degree of buffering and heat insulation. Polyester fiber has good flexibility and wear resistance, while glass fiber has high strength and corrosion resistance. The fiber woven mesh formed by the two intertwines serves as the reinforcing layer 3, fully combining the characteristics of the two fibers. While enhancing the strength of the pipe, it also improves its wear resistance and corrosion resistance, further extending the service life of the cast rubber pipe.

[0023] The nano-titanium dioxide composite coating possesses excellent photocatalytic, UV resistance, and self-cleaning properties. Coated onto the outer surface of the outer tube layer 2, it effectively absorbs and scatters ultraviolet rays, reducing UV damage to the tetrahydrofuran material and thus significantly improving the aging resistance of the cast iron pipe. The spraying process ensures uniform coating coverage, guaranteeing consistent protective effects.

[0024] The polytetrafluoroethylene coating has extremely strong chemical stability and corrosion resistance. As the anti-corrosion layer 6 on the inner surface of the inner tube layer 1, it can effectively prevent the transported medium from eroding the inside of the tube. It is especially suitable for transporting corrosive liquids or gases and extends the service life of the cast rubber tube.

[0025] The mating of internal threads 8 and external threads 9 facilitates the connection and disassembly of cast iron tubing, eliminating the need for additional connecting fittings, simplifying the installation process, and improving installation efficiency. Simultaneously, the threaded connection ensures tightness and sealing, preventing media leakage. The one-piece molded connector 7 provides better integrity and consistency with the tubing body, avoiding stress concentration and weak connections that may occur due to different materials at the connection points. Furthermore, the uniform material ensures the uniformity of performance across the entire cast iron tubing, improving its reliability and stability. The protective alloy component 5 fits tightly against the tubing body near the pipe, providing stable support and protection; its wider design further away from the pipe body expands the protection range, enhancing the protection against the sides of the tubing and better resisting external collisions and impacts, further improving the safety of the cast iron tubing.

[0026] Working Principle: In practical use, this aging-resistant tetrahydrofuran cast rubber pipe functions effectively due to its unique structural design. The pipe body consists of an inner pipe layer 1, a reinforcing layer 3, and an outer pipe layer 2. The inner surface of the inner pipe layer 1 is coated with a polytetrafluoroethylene anti-corrosion layer 6, which can effectively resist the corrosion of the transported medium, making it suitable for conveying corrosive fluids in chemical, petroleum, and other applications. The reinforcing layer 3 uses a fiber woven mesh of polyester fiber and glass fiber to enhance the strength of the pipe body and ensure stable transportation under high pressure.

[0027] The nano-titanium dioxide composite anti-aging coating 4 on the outer surface of the outer tube layer 2 slows down the aging rate of the tube body by absorbing and scattering ultraviolet rays. The spiral protective alloy component 5 is installed on the outside of the tube body; its shape, narrow near the tube body and wide away from it, not only provides support by tightly fitting the tube body but also expands the protective range, effectively resisting external impacts. Its hollow layer also acts as a buffer and heat insulation. With these structural advantages, this cast rubber tube can operate stably in complex environments, providing reliable protection for fluid transportation.
