[0003] Existing PVC pipes have poor wear resistance. During long-term use, especially during the dragging process during laying, the pipe wall is easily worn, which reduces the strength of the pipe body and may eventually lead to safety accidents such as pipe leakage. In addition, when PVC pipes are used outdoors or in harsh environments, they are easily affected by ultraviolet radiation, which causes the pipe to age, become brittle, and develop cracks and discoloration on the surface.

[0004] Therefore, a wear-resistant PVC pipe is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a wear-resistant PVC pipe that can solve the problems of poor wear resistance of existing PVC pipes. During long-term use, especially during the dragging process of laying, the pipe wall is easily worn, which leads to a decrease in the strength of the pipe body and may eventually cause safety accidents such as pipe leakage. In addition, when PVC pipes are used outdoors or in harsh environments, they are easily affected by ultraviolet radiation, which leads to pipe aging, brittleness, cracking and discoloration on the surface.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A wear-resistant PVC pipe includes a PVC pipe body 1, an installation component 2 is sleeved on the surface of the PVC pipe body 1, and an installation plate 3 is provided at the bottom of the installation component 2.

[0027] The PVC pipe body 1 includes a main body layer 11, a reinforcing layer 12 is provided on the surface of the main body layer 11, an anti-aging layer 13 is provided on the surface of the reinforcing layer 12, and a wear-resistant layer 14 is provided on the surface of the anti-aging layer 13.

[0028] In this embodiment: by setting the PVC pipe body 1 with a carefully designed structure of each layer, it has a significant overall effect in many aspects. The composite structure of the main body layer 11, the reinforcing layer 12, the anti-aging layer 13 and the wear-resistant layer 14 gives the pipe high strength, aging resistance and wear resistance and other excellent properties, which fundamentally improves the quality and service life of the pipe. The reinforcing layer 12 provides strong mechanical support for the pipe, the anti-aging layer 13 effectively resists ultraviolet corrosion, and the wear-resistant layer 14 reduces wear. The layers work together to ensure that the pipe maintains stable performance in complex environments and during long-term use.

[0029] Specifically, such as Figure 2 As shown, the installation component 2 includes an upper retaining ring 21 and a lower retaining ring 22. The upper retaining ring 21 and the lower retaining ring 22 are respectively fitted onto the top and bottom of the surface of the PVC pipe body 1. The inner walls of the upper retaining ring 21 and the lower retaining ring 22 are provided with rubber pads 23, and the side of the rubber pads 23 closest to the PVC pipe body 1 is in close contact with them.

[0030] Specifically, such as Figure 2As shown, both sides of the upper retaining ring 21 and the lower retaining ring 22 are provided with connecting blocks 24. A bolt passes through the interior of the top connecting block 24, and the bottom of the bolt extends into the interior of the bottom connecting block 24 and is threadedly connected to it.

[0031] In this embodiment: by setting the installation component 2, through the cooperation of the upper retaining ring 21, the lower retaining ring 22, the connecting block 24, the mounting plate 3 and the bolts, the PVC pipe body 1 can be fixed in position when used in high-rise drainage projects. Furthermore, through the rubber pad 23, the PVC pipe body 1 is in flexible contact with the upper retaining ring 21 and the lower retaining ring 22, which can reduce the wear between the pipe and the pipe clamp caused by drainage vibration, and further protect the PVC pipe body 1.

[0032] Specifically, such as Figure 5 As shown, the reinforcing layer 12 is composed of high-strength glass fiber filaments and is woven into a mesh to cover the surface of the PVC pipe body 1.

[0033] Specifically, such as Figure 5 As shown, the anti-aging layer 13 is composed of an ultraviolet absorber and is uniformly coated on the surface of the reinforcing layer 12.

[0034] Specifically, such as Figure 5 As shown, the wear-resistant layer 14 is composed of polyurethane coating and is uniformly coated on the surface of the anti-aging layer 13.

[0035] In this embodiment: A reinforcing layer 12 composed of high-strength glass fiber filaments is woven into a mesh and wrapped around the surface of the PVC pipe body 1. Glass fiber filaments have high strength and high modulus characteristics, and their mesh structure can evenly disperse the external forces, such as pressure, tension, and impact, that the pipe is subjected to during use. This effectively enhances the pipe's tensile, bending, and impact resistance, preventing the pipe from cracking or deforming due to excessive force, and greatly improving the structural stability and reliability of the pipe. An anti-aging layer 13 composed of ultraviolet absorbers is evenly coated on the surface of the reinforcing layer 12, which can effectively absorb ultraviolet radiation. In outdoor or ultraviolet-exposed environments, it can prevent ultraviolet rays from photodegrading the PVC pipe body 1 and its internal layers, preventing the pipe from aging, becoming brittle, discoloring, or cracking due to long-term ultraviolet exposure. A wear-resistant layer 14 composed of polyurethane coating is evenly coated on the surface of the anti-aging layer 13. Polyurethane has excellent wear resistance, impact resistance, and a low coefficient of friction, reducing wear during use and installation, and ensuring that the pipe maintains stable performance in complex environments and during long-term use.

[0036] Specifically, such as Figure 3As shown, the bottom of the lower retaining ring 22 is threaded with a stud 4, and the stud 4 is threadedly connected to the mounting plate 3. A damping spring 5 is provided between the rubber pad 23 and the inner wall of the upper retaining ring 21 and the lower retaining ring 22.

[0037] In this embodiment: by setting the stud 4, the lower retaining ring 22 can be connected to the mounting plate 3, which facilitates the disassembly and assembly of the mounting assembly 2. By setting the damping spring 5, when the pipe is subjected to vibration and impact, the damping spring 5 can absorb and disperse energy, reduce the impact of external force on the pipe and connection parts, prevent stress concentration and damage caused by rigid connection, and improve the stability and durability of the pipe after installation.

[0038] Specifically, such as Figure 4 As shown, the PVC pipe body 1 includes an inner pipe body 6 and an outer pipe body 7. Several reinforcing ribs 8 are arranged in a ring between opposite sides of the inner pipe body 6 and the outer pipe body 7. The inner wall of the inner pipe body 6 is provided with spiral ribs 9 in a ring.

[0039] In this embodiment, the PVC pipe body 1 is composed of an inner pipe body 6, an outer pipe body 7, and a reinforcing rib 8 in the middle. The reinforcing rib 8 is distributed in a ring between the inner pipe body 6 and the outer pipe body 7, which effectively enhances the overall strength and rigidity of the pipe. The inner wall of the inner pipe body 6 is provided with spiral ribs 9. During the fluid transportation process, the spiral ribs 9 can guide the fluid to form a spiral flow, increase the contact area and flow path between the fluid and the pipe wall, help reduce the direct scouring force of the fluid on the pipe wall, reduce the degree of wear, and at the same time, it can also enhance the pressure resistance of the pipe to a certain extent, making the pipe perform better in fluid transportation applications.

[0040] Working principle: During the installation of the PVC pipe body 1, the mounting plate 3 can be pre-fixed to the pipe installation position using expansion bolts or other structures. Then, the lower retaining ring 22 is connected to the mounting plate 3 by the threaded engagement of the stud 4 with the lower retaining ring 22. The PVC pipe body 1 is then placed inside the lower retaining ring 22, and the upper retaining ring 21 is fitted onto the pipe surface. Bolts are then used to secure the upper retaining ring 21 to the lower retaining ring 22, thus completing the pipe fixing. When the pipe is subjected to vibration or impact, the damping spring 5 and rubber pad 23 can absorb and disperse energy, reducing the impact of external forces on the pipe and installation. The influence between components 2, and the careful design of the structure of each layer of the PVC pipe body 1, have many significant overall effects. The composite structure of the main body layer 11, the reinforcing layer 12, the anti-aging layer 13 and the wear-resistant layer 14 gives the pipe high strength, aging resistance and wear resistance and other excellent properties, which fundamentally improves the quality and service life of the pipe. The reinforcing layer 12 provides strong mechanical support for the pipe, the anti-aging layer 13 effectively resists ultraviolet corrosion, and the wear-resistant layer 14 reduces wear. The layers work together to ensure that the pipe maintains stable performance in complex environments and during long-term use.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
