Description

Technical Field

[0001] This utility model relates to the field of water supply pipe technology, and in particular to an antibacterial PE water supply pipe. Background Technology

[0002] PE water supply pipes are a replacement for traditional steel pipes and polyvinyl chloride drinking water pipes. Their wear resistance, acid and corrosion resistance, high temperature resistance, and high pressure resistance have gradually replaced traditional pipes such as steel pipes and cement pipes in the market. In particular, because these pipes are lightweight and easy to install and move, they are the first choice for new materials.

[0003] Traditional PE water supply pipes have poor resistance and are not pressure resistant. If they are subjected to excessive pressure, they are prone to rupture, leading to water leakage accidents, which will affect production or daily life.

[0004] The existing patent (publication number: CN205664006U) discloses a high-resistance, high-pressure resistant PE water supply pipe. The advantages of this utility model are: it has a certain rigidity and pressure resistance, not only is it wear-resistant and not easy to wear, but it also has good toughness and high elasticity, thus improving product quality.

[0005] To address the aforementioned issues, existing patents offer solutions. While these solutions provide PE pipes with good pressure resistance, bacteria, algae, and other microorganisms can easily grow on the pipe walls during long-term use. As these microorganisms multiply, they form biofilms that adhere to the pipe surface. These biofilms not only corrode the pipes and shorten their lifespan but also release harmful substances that pollute the water, leading to excessive levels of bacteria in the water and affecting the safety of residents' drinking water.

[0006] Therefore, an antibacterial PE water supply pipe is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide an antibacterial PE water supply pipe that can solve the problem that bacteria, algae and other microorganisms easily grow on the pipe wall during long-term use of existing PE pipes. After these microorganisms multiply in large quantities, they form a biofilm that adheres to the pipe wall surface. The biofilm not only corrodes the pipe material and shortens its service life, but also releases harmful substances that pollute the water quality, resulting in an excessive total number of bacteria in the water and affecting the safety of residents' drinking water.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an antibacterial PE water supply pipe, comprising a PE water supply pipe body, wherein the PE water supply pipe body comprises a polyethylene main layer, a transition layer, a reinforcing layer, an anti-permeability layer and an outer protective layer arranged sequentially from the inside to the outside, wherein an antibacterial layer is provided on the inner wall of the polyethylene main layer, wherein the antibacterial layer is composed of a silver-loaded zirconium phosphate antibacterial agent coating, and wherein a plurality of raised guide ridges are evenly distributed along the axial direction on the inner wall of the polyethylene main layer.

[0009] Preferably, the transition layer is composed of an ethylene-ethyl acrylate copolymer layer, and the thickness of the ethylene-ethyl acrylate copolymer layer is 0.3-0.5 mm.

[0010] Preferably, the reinforcing layer is composed of a basalt fiber reinforced polyethylene layer.

[0011] Preferably, the reinforcing layer is provided with annular reinforcing rings at intervals, and the annular reinforcing rings are woven from polyacrylonitrile fibers.

[0012] Preferably, the impermeable layer is composed of an ethylene-vinyl alcohol copolymer layer, and the thickness of the ethylene-vinyl alcohol copolymer layer is 0.2-0.4 mm.

[0013] Preferably, the 99.

[0014] Preferably, the height of the guide rib is 0.1-0.2 mm, and the cross-section is an equilateral triangle.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application uses an antibacterial layer on the inner wall to release antibacterial ions to inhibit bacterial growth. Furthermore, during fluid transport, the guide ridges guide the water flow to form micro-turbulence. This reduces the boundary layer thickness near the pipe wall, decreasing the likelihood of microbial attachment. Additionally, the micro-turbulence enhances the scouring effect of the water flow on the pipe wall, making it difficult for microorganisms attached to the pipe wall to form a stable biofilm, further ensuring water quality. Moreover, the impermeable layer blocks oxygen from penetrating into the pipe, thereby inhibiting the growth of aerobic bacteria. Therefore, the three layers work together to cut off the biofilm formation path, ensuring water safety.

[0017] 2. This application forms a rigid support network through the reinforcing layer and the annular reinforcing ring, which enhances the circumferential strength of the pipe. This allows the pipe to better maintain its circular cross-sectional shape when subjected to external pressure (such as soil pressure when buried), preventing pipe deformation and improving the overall stability and reliability of the pipe. The transition layer enhances the bonding force between the layers, making the pipe less prone to breakage when subjected to water pressure and external loads, ensuring water delivery safety. The outer protective layer can resist ultraviolet radiation, prevent pipe aging, and extend service life. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-4 The present invention provides the following technical solution:

[0025] An antibacterial PE water supply pipe includes a PE water supply pipe body 1. The PE water supply pipe body 1 includes a polyethylene main layer 2, a transition layer 3, a reinforcing layer 4, an anti-permeability layer 5, and an outer protective layer 6 arranged sequentially from the inside to the outside. An antibacterial layer 7 is provided on the inner wall of the polyethylene main layer 2. The antibacterial layer 7 is composed of a silver-loaded zirconium phosphate antibacterial agent coating. Several raised guide ridges 8 are evenly distributed along the axial direction on the inner wall of the polyethylene main layer 2.

[0026] In this embodiment: the antibacterial layer 7 on the inner wall releases antibacterial ions to inhibit bacterial reproduction. During fluid transport, the guide ridge 8 guides the water flow to form micro-turbulence, which reduces the boundary layer thickness near the pipe wall and lowers the possibility of microbial attachment. On the other hand, the micro-turbulence enhances the scouring effect of the water flow on the pipe wall, making it difficult for microorganisms attached to the pipe wall to form a stable biofilm, further ensuring water quality. The anti-permeability layer 5 blocks oxygen from penetrating into the pipe, thereby inhibiting the growth of aerobic bacteria. Therefore, the three layers work together to cut off the biofilm formation path and ensure water safety. The reinforcing layer 4 and the annular reinforcing ring 9 form a rigid support network, which enhances the circumferential strength of the pipe. When the pipe is subjected to external pressure (such as soil pressure when buried), it can better maintain the circular cross-sectional shape, prevent pipe deformation, and improve the overall stability and reliability of the pipe. The transition layer 3 enhances the bonding force of each layer, making the pipe less prone to breakage when subjected to water pressure and external loads, ensuring water transport safety. The outer protective layer 6 can resist ultraviolet radiation, prevent pipe aging, and extend service life.

[0027] Specifically, such as Figure 2As shown, the transition layer 3 is composed of an ethylene-ethyl acrylate copolymer layer, and the thickness of the ethylene-ethyl acrylate copolymer layer is 0.3-0.5 mm.

[0028] Specifically, such as Figure 2 As shown, the reinforcing layer 4 is composed of basalt fiber reinforced polyethylene layer.

[0029] Specifically, such as Figure 3 As shown, the reinforcing layer 4 has annular reinforcing rings 9 spaced apart inside, and the annular reinforcing rings 9 are woven from polyacrylonitrile fibers.

[0030] In this embodiment: the ethylene-ethyl acrylate copolymer layer 3 is used to eliminate interlayer stress concentration by utilizing the flexibility and adhesion of the ethylene-ethyl acrylate copolymer layer, avoiding delamination caused by differences in material thermal expansion, ensuring the integrity of the composite structure, and also having a stress buffering effect. When the pipe is subjected to water pressure or external impact, the ethylene-ethyl acrylate copolymer layer absorbs energy through elastic deformation, preventing the polyethylene main layer 2 and the reinforcing layer 4 from directly cracking under stress. The reinforcing layer 4 is composed of basalt fiber reinforced polyethylene layer. The high strength and high modulus characteristics of basalt fiber give the pipe tensile and bending resistance, resisting radial expansion caused by water pressure and deformation caused by soil pressure, maintaining the circular cross-section of the pipe. The annular reinforcing ring 9 can be used in conjunction with the reinforcing layer 4 to improve the pipe's ability to resist external radial extrusion.

[0031] Specifically, such as Figure 2 As shown, the impermeable layer 5 is composed of an ethylene-vinyl alcohol copolymer layer, and the thickness of the ethylene-vinyl alcohol copolymer layer is 0.2-0.4 mm.

[0032] Specifically, such as Figure 2 As shown, the outer protective layer 6 is composed of a high-density polyethylene layer modified with ultraviolet absorbers.

[0033] In this embodiment: the anti-permeability layer 5 is composed of an ethylene-vinyl alcohol copolymer layer. The low permeability of the ethylene-vinyl alcohol copolymer layer prevents external oxygen from seeping into the pipe, inhibits the reproduction of aerobic microorganisms, and blocks the penetration of harmful substances in the soil, thus avoiding water pollution; the outer protective layer 6 is composed of a UV absorber modified high-density polyethylene layer. The UV absorber modified high-density polyethylene layer can resist UV radiation, prevent pipe aging, and extend service life.

[0034] Specifically, such as Figure 4 As shown, the height of the guide rib 8 is 0.1-0.2mm, and the cross-section is an equilateral triangle.

[0035] In this embodiment: the raised guide ridge 8 changes the water flow boundary layer, making it difficult for microorganisms to attach and form a biofilm. At the same time, the turbulent scouring force is enhanced, stripping away the attached bacteria. The equilateral triangular cross-section design generates moderate turbulence when guiding the water flow, which ensures the scouring effect and avoids energy loss caused by excessive turbulence, thus achieving a balance between antibacterial and water delivery efficiency.

[0036] Working principle: When the PE pipe body 1 is in use, the antibacterial layer 7 on the inner wall releases antibacterial ions to inhibit bacterial reproduction. During fluid transportation, the guide ridge 8 guides the water flow to form micro-turbulence, which reduces the thickness of the boundary layer near the pipe wall, thus reducing the possibility of microbial attachment. On the other hand, the micro-turbulence enhances the scouring effect of the water flow on the pipe wall, making it difficult for microorganisms attached to the pipe wall to form a stable biofilm, further ensuring water quality. The anti-permeability layer 5 blocks oxygen from penetrating into the pipe, thereby inhibiting the growth of aerobic bacteria. Therefore, the three layers work together to cut off the biofilm formation path and ensure water safety. The reinforcing layer 4 and the annular reinforcing ring 9 form a rigid support network, which enhances the circumferential strength of the pipe. When the pipe is subjected to external pressure (such as soil pressure when buried), it can better maintain the circular cross-sectional shape, prevent pipe deformation, and improve the overall stability and reliability of the pipe. The transition layer 3 enhances the bonding force of each layer, making the pipe less prone to breakage when subjected to water pressure and external loads, ensuring water transportation safety. The outer protective layer 6 can resist ultraviolet radiation, prevent pipe aging, and extend service life.

[0037] 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.
