Description

TECHNICAL FIELD

[0001] The utility model relates to PVC water pipe technical field, especially a kind of high-pressure PVC water pipe. BACKGROUND

[0002] In modern industry and daily life, water pipes are widely used to transport various liquids, such as tap water, industrial water, chemical liquids, etc. High-pressure PVC water pipes are made of polyvinyl chloride as the main raw material and are formed by extrusion molding process for transporting high-pressure liquids.

[0003] The PVC water pipe in the prior art has inner and outer layers, and a woven mesh is added between the two layers to enhance the pressure resistance of the water pipe. However, the woven mesh fills the space between the inner and outer layers, which requires more materials and increases the manufacturing cost. In addition, when the water pipe is partially cracked, it cannot be isolated, so the total valve must be closed and the water source in the pipeline must be completely drained before the pipeline can be replaced, which is inconvenient for maintenance.

[0004] The existing patent (publication number: CN215258477U) discloses a high-pressure PVC water pipe to solve the problems in the prior art. It includes a water pipe body, which includes an outer pipe, an inner pipe, and an end head. The hollow layer is formed between the outer pipe and the inner pipe, and the hollow layer is filled with a ring-shaped distribution of pressure-resistant metal mesh. The pressure-resistant metal mesh is connected by elastic connecting members. The outer pipe and the inner pipe are fixedly connected to the end head, which is ring-shaped. The water pipe body is divided into an outer pipe and an inner pipe by the pressure-resistant metal mesh, the inner pipe can expand and reduce pressure after being pressed, and the pressure-resistant metal mesh is assembled by four parts and connected by rubber. The use of materials is small, and the manufacturing cost is low.

[0005] To solve the above problems, the existing patent provides a solution. However, the existing PVC water pipe has limited pressure-bearing capacity in high-pressure environments, which can easily cause cracking, deformation, and other problems, and cannot meet the growing demand for high-pressure transportation. Although metal water pipes have high strength, they have the disadvantages of easy rust and corrosion, heavy weight, inconvenient installation, high cost, and other shortcomings. In addition, some existing high-pressure water pipes are subjected to long-term high-pressure water flow impact and complex external environmental effects, which can cause cracks, ruptures, and even pipe explosions in the water pipe wall.

[0029] Specifically, as shown in Figure 2 , Figure 4 , reinforcing layer 102 is a woven steel wire mesh layer, and the material of outer tube layer 103 is modified polyvinyl chloride.

[0030] Specifically, as shown in Figure 2 , Figure 3 , the surface of inner tube layer 101 is bonded with an adhesive layer 104, and reinforcing layer 102 is bonded to the surface of inner tube layer 101 through the adhesive layer 104.

[0032] In this embodiment: by setting the reinforcing layer 102 as a woven steel wire mesh layer, the overall strength and pressure bearing capacity of the water pipe structure 1 are improved, so that the water pipe structure 1 can stably cope with the impact of high-pressure water flow, effectively prevent the water pipe structure 1 from being broken due to excessive pressure, and ensure the safety and stability of high-pressure liquid transportation. The adhesive layer 104 between the inner pipe layer 101 and the reinforcing layer 102 and the hot melt adhesive layer 105 between the reinforcing layer 102 and the outer pipe layer 103 ensure the tight and firm connection between the layers, forming an organic whole structure, effectively avoiding the phenomenon of delamination and peeling of each layer due to uneven stress in the long-term use process, maintaining the integrity and stability of the water pipe structure 1, thereby ensuring that the water pipe structure 1 can work reliably and continuously under complex working conditions.

[0033] Specifically, as shown in Figure 2 , Figure 4 , the surface of the outer pipe layer 103 is coated with a corrosion-resistant coating 106, and the material of the corrosion-resistant coating 106 is epoxy resin.

[0034] Specifically, as shown in Figure 2 , Figure 4 , the surface of the corrosion-resistant coating 106 is provided with a protective layer 107, and the material of the protective layer 107 is polyurethane elastomer.

[0035] In this embodiment: the epoxy resin corrosion-resistant coating 106 on the surface of the outer pipe layer 103 can form a dense protective barrier on the surface of the water pipe structure 1, effectively isolating external corrosive substances such as acid-base solution, humid air, and chemical impurities in water, reducing the risk of corrosion of the water pipe structure 1, prolonging the service life of the water pipe structure 1, reducing leakage and maintenance caused by corrosion, and reducing use cost and safety hazards. The protective layer 107 is made of polyurethane elastomer, which has excellent wear resistance and flexibility, so that the water pipe structure 1 can be effectively buffered and protected when subjected to external friction, collision and other mechanical damage, avoiding scratches, wear and other damage to the water pipe structure 1 caused by slight external force, and maintaining the appearance integrity and structural stability of the water pipe structure 1.

[0036] Specifically, as shown in Figure 1 , Figure 5 , the inner wall of the reinforcing assembly 3 is fixedly connected with a reinforcing rib 4, and the material of the reinforcing pad 2 is rubber.

[0038] In the embodiment, the reinforcing rib 4 in the reinforcing assembly 3 provides additional strength support, enhances the anti-deformation ability of the water pipe structure 1 when subjected to external force, so that the water pipe structure 1 can better maintain shape stability under complex installation and use conditions, such as uneven soil pressure, natural disasters such as earthquakes or external force impact, prevent the water pipe structure 1 from being deformed, such as bending, twisting, and ensure the normal operation of the water pipe structure 1 system, the reinforcing pad 2 made of rubber material not only has good elasticity, can absorb and disperse the impact force from the outside, reduce the direct damage to the water pipe structure 1, the combination structure of the first fixing ring 301, the protective frame 302 and the second fixing ring 303 further enhances the connection stability of the reinforcing pad 2 and the water pipe structure 1, and ensures that the reinforcing assembly 3 can always effectively play its protection role in the long-term use process.

[0039] Working principle: during the use of the water pipe structure 1, when the high-pressure water flow passes through the inner pipe layer 101, the chemical stability of the polyvinyl chloride resin material of the inner pipe layer 101 ensures that the quality of the transported liquid is not affected by the pipe wall material, and the smooth surface of the inner wall reduces the water flow resistance, so that the water flow can pass through efficiently and smoothly, the woven steel wire mesh structure of the reinforcing layer 102 uniformly disperses the pressure generated by the water flow to the entire cross section of the water pipe structure 1, effectively preventing the risk of rupture caused by excessive local pressure, providing strong pressure-bearing capacity support for the water pipe structure 1, the modified polyvinyl chloride material of the outer pipe layer 103, the corrosion-resistant coating 106 and the protective layer 107 jointly resist various physical and chemical erosion from the outside, and protect the internal structure from being damaged, when the water pipe structure 1 is subjected to external impact force or displacement due to environmental factors, the rubber material of the reinforcing pad 2 first plays a buffering role, absorbs part of the energy, and reduces the impact on the water pipe structure 1, while the reinforcing assembly 3 and the reinforcing rib 4 limit the deformation of the water pipe structure 1, maintain its overall stability and structural integrity.

[0040] The above is only a preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
