[0002] Teflon tubing is extruded from polytetrafluoroethylene resin. The product is resistant to high temperatures, wear and corrosion, non-stick and weathering. According to the wall thickness and voltage resistance level of the product, Teflon tubing can be divided into three types: S-type, T-type and L-type. The current pressure resistance of Teflon tubing is usually achieved through the characteristics of the material itself, which will result in the pressure resistance of the tubing being very limited, and usually cannot effectively protect the internal pipes.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-Figure 3 A pressure-resistant Teflon casing comprises a Teflon tube 1. A buffer layer 2 is provided on the surface of the Teflon tube 1, and a reinforcing fiber layer 3 is provided on the surface of the buffer layer 2. A pressure-resistant layer 4 is provided on the surface of the fiber layer 3, and connecting strips 5 are provided on the surface of the pressure-resistant layer 4 in an annular manner and equidistantly. A connecting ring 6 is connected to the surface of the pressure-resistant layer 4, and a shell 7 is connected to the surface of the connecting ring 6. The shell 7 not only has excellent pressure resistance, but also can protect the internal buffer layer 2 and the reinforcing fiber layer 3 from erosion by the external environment. The shell 7 provides an additional protective barrier for the casing, making it more sturdy and durable when facing extreme pressure or impact. The connecting ring 6 and the support strip 9 help prevent the casing from deformation or collapse under high pressure.

[0025] Furthermore, grooves 8 are equidistantly provided on the surface of the connecting ring 6 , and support bars 9 are inserted into the grooves 8 , so that the connecting ring 6 can contact the surface of the housing 7 through the support bars 9 .

[0026] Furthermore, the material of the buffer layer 2 is silicone. One or more buffer layers 2 are arranged on the outer surface of the Teflon sleeve. The buffer layer 2 is usually made of a material with excellent elasticity and pressure resistance, such as rubber, silicone or other polymer materials. When the sleeve is subjected to external pressure, the buffer layer 2 can absorb and disperse part of the pressure, thereby reducing the direct impact on the internal pipeline of the sleeve and improving its pressure resistance.

[0027] Furthermore, the fiber layer 3 is made of glass fiber, and a reinforcing fiber layer 3, such as glass fiber, carbon fiber, etc., is wrapped on the outside of the buffer layer 2 or the outer surface of the sleeve. These fiber materials have high strength and high modulus, and can effectively enhance the compression and tensile strength of the sleeve. The reinforcing fiber layer 3 can significantly improve the overall strength of the sleeve, making it less likely to deform or break when facing a high-pressure environment.

[0028] Furthermore, the pressure-resistant layer 4 is circular and wavy, and the material of the pressure-resistant layer 4 is rubber. The circular and wavy pressure-resistant layer 4 can form a buffer zone, thereby improving the pressure resistance of the casing through the buffer effect.

[0029] Furthermore, the surface of the outer shell 7 is provided with a wear-resistant layer, which is used to prevent the surface of the outer shell 7 from being damaged by wear.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
