Description

Technical Field

[0001] This utility model relates to the field of pipe technology, and in particular to a pressure-resistant PE water pipe structure. Background Technology

[0002] PE water pipes are plastic pipes made primarily of polyethylene. They possess excellent comprehensive performance and are widely used in water supply and drainage, gas transmission, agricultural irrigation, and other fields.

[0003] Traditional PE water pipes have a relatively simple structure, typically relying on a single layer of PE material to withstand external pressure. While this single-layer structure may maintain normal operation under relatively mild pressure, it is prone to deformation or even rupture under greater external pressure. This not only wastes water resources but also damages the surrounding environment, disrupts project progress, and increases maintenance and time costs. Secondly, traditional PE water pipes lack effective pressure dispersion structures. When local pressure is too high, they are prone to local deformation and rupture, leading to leaks in the entire water system and severely impacting the pipes' normal use and lifespan. Furthermore, traditional PE water pipes become less resilient at low temperatures, making them more susceptible to rupture under pressure. At high temperatures, the PE material softens, reducing its compressive strength, making the pipes highly susceptible to deformation under external pressure and shortening their lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a pressure-resistant PE water pipe structure to solve the technical problems existing in the prior art.

[0005] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0006] A pressure-resistant PE water pipe structure includes: a PE pipe body, a fourth pressure-resistant layer outer sleeve of the PE pipe body, the fourth pressure-resistant layer being a protective layer with preset corrosion resistance, used to resist external pressure; and a first pressure-resistant layer between the PE pipe body and the fourth pressure-resistant layer, the first pressure-resistant layer being an inner protective layer with preset toughness, used to protect the PE pipe body.

[0007] Furthermore, the fourth pressure-resistant layer has a preset thickness and elasticity, and multiple slow-release grooves are formed on it. The slow-release grooves are wedge-shaped and distributed in a ring array along the central axis of the PE pipe body.

[0008] Furthermore, the first pressure-resistant layer is covered by a second pressure-resistant layer, which is a pressure-dispersing layer with a preset strength and is made of a cross-shaped fiber web; the outer diameter of the second pressure-resistant layer is smaller than that of the fourth pressure-resistant layer.

[0009] Furthermore, the second pressure-resistant layer is covered by a third pressure-resistant layer, which is a buffer layer with a preset elasticity. Its outer wall is provided with multiple buffer strips, which are made of natural rubber and are located between the third and fourth pressure-resistant layers. The outer diameter of the third pressure-resistant layer is larger than that of the second pressure-resistant layer.

[0010] Furthermore, the fourth compressive layer is made of high-density polyethylene material.

[0011] Furthermore, the third compressive layer is made of a highly elastic rubber material.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (I) This utility model sets up multiple pressure-resistant layers. From the inside to the outside of the PE pipe body, there are a first pressure-resistant layer, a second pressure-resistant layer, a third pressure-resistant layer and a fourth pressure-resistant layer. Each layer works closely together to comprehensively improve the pressure resistance of the water pipe, so that the water pipe can withstand greater external pressure than ordinary water pipes and improve its pressure resistance.

[0014] (II) By opening a slow-release groove on the fourth pressure-resistant layer and providing a buffer strip on the outer wall of the third pressure-resistant layer, when the water pipe is subjected to external pressure, the slow-release groove can change the direction of pressure transmission, so that the pressure gradually diffuses in the slow-release groove, avoiding damage to the fourth pressure-resistant layer caused by excessive local pressure. The buffer strip will undergo elastic deformation when it is compressed, thereby absorbing a large amount of pressure energy, further improving the pressure resistance of the entire water pipe structure, so that the water pipe can better protect the internal PE pipe body when subjected to impact pressure.

[0015] (III) The fourth pressure-resistant layer of this utility model is made of high-density ethylene material, which has high strength, high rigidity and good wear resistance and chemical corrosion resistance. It can directly resist large external pressure and protect the internal layers from damage. It can also operate stably in various complex chemical environments, resist the corrosion of chemicals such as acids and alkalis, and extend the service life of water pipes.

[0020] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] like Figure 1-3 As shown, this embodiment provides a pressure-resistant PE water pipe structure, including: a PE pipe body 1, with a fourth pressure-resistant layer 5 outer sleeved on the PE pipe body 1. The fourth pressure-resistant layer 5 is a protective layer with preset corrosion resistance, made of high-density polyethylene material. The high-density polyethylene material has high strength, high rigidity, and good wear resistance and chemical corrosion resistance. The fourth pressure-resistant layer 5 is used to resist external pressure. When facing external pressure, the fourth pressure-resistant layer 5 can buffer part of the pressure through its own deformation, effectively reducing the impact of external pressure on the internal structure. Furthermore, it can maintain stability in various complex environments, whether acidic or alkaline, or in humid soil environments. The four pressure-resistant layers 5 can resist the erosion of external chemical substances for a long time, thus maintaining the integrity of its structure and the stability of its performance, providing reliable external protection for the device and effectively resisting various pressures from the outside. A first pressure-resistant layer 2 is provided between the PE pipe body 1 and the fourth pressure-resistant layer 5. The first pressure-resistant layer 2 is an inner protective layer with preset toughness, which is used to protect the PE pipe body 1. The first pressure-resistant layer 2 is tightly arranged around the outer wall of the PE pipe body 1. When the water pipe is subjected to external pressure, the first pressure-resistant layer 2 can absorb and disperse part of the pressure, preventing the PE pipe body 1 from directly bearing excessive pressure, thereby effectively preventing the PE pipe body 1 from cracking or being damaged due to excessive pressure.

[0022] like Figure 1-2 As shown, the fourth pressure-resistant layer 5 has a preset thickness and elasticity, and multiple slow-release grooves 7 are formed on it. The slow-release grooves 7 are wedge-shaped and distributed in a ring array along the central axis of the PE pipe body 1. Specifically, the slow-release grooves 7 are trapezoidal. When the fourth pressure-resistant layer 5 is subjected to external pressure, the slow-release grooves 7 change the direction of external pressure transmission, avoid excessive pressure concentration at a certain point, effectively prevent excessive local pressure from damaging the fourth pressure-resistant layer 5, further enhance the ability of the fourth pressure-resistant layer 5 to resist external pressure, and make the pressure resistance of this device stronger.

[0023] Furthermore, the first pressure-resistant layer 2 is covered by a second pressure-resistant layer 3. The second pressure-resistant layer 3 is a pressure-dispersing layer with a preset strength. It is made of a cross-shaped fiber mesh, which can evenly disperse pressure when subjected to pressure, preventing pressure concentration in one place and thus avoiding damage to the water pipe. The outer diameter of the second pressure-resistant layer 3 is smaller than that of the fourth pressure-resistant layer 5. The second pressure-resistant layer 3 is covered by a third pressure-resistant layer 4, which is made of a highly elastic rubber material. The third pressure-resistant layer 4 is a buffer layer with a preset elasticity, which can quickly and significantly expand when subjected to pressure. The elastic deformation effectively absorbs a large amount of pressure energy, further improving the pressure resistance of the device; the outer wall of the third pressure-resistant layer 4 is provided with multiple buffer strips 6, which are made of natural rubber and are located between the third pressure-resistant layer 4 and the fourth pressure-resistant layer 5. After being subjected to pressure, the buffer strips 6 absorb and buffer the pressure through their own elastic deformation, sharing the pressure impact for the third pressure-resistant layer 4; the outer diameter of the third pressure-resistant layer 4 is larger than that of the second pressure-resistant layer 3; the first pressure-resistant layer 2, the second pressure-resistant layer 3, the third pressure-resistant layer 4 and the fourth pressure-resistant layer 5 are tightly fitted together, comprehensively improving the pressure resistance of the device.
