Abstract
Description
Technical Field
[0001] This utility model relates to the field of PE drip pipes, specifically a corrosion-resistant PE drip pipe. Background Technology
[0002] PE drip irrigation pipes, also known as drip irrigation pipes, are water-saving products. The uniformity of water flow from internally embedded drip irrigation pipes (tapes) is higher than that from side-wing drip irrigation tapes. They have a wide range of applications, can be laid in long lengths, and are available in 1.38 liters and 2.5 liters per minute. Wall thickness varies from 0.2 to 0.6 mm. They employ embedded labyrinth flow-throttling and labyrinth compensation drippers, creating turbulent flow. They have strong self-cleaning and anti-clogging capabilities, and the filtration level is relaxed to 80 mesh.
[0003] Currently, drip irrigation pipes are typically placed on soil and fields for drip irrigation. However, existing drip irrigation pipes are susceptible to corrosion from soil, fertilizers, and pesticides, leading to gaps or reduced toughness due to corrosion. Furthermore, drip irrigation pipes are often dragged on the field, causing them to break or tear, creating holes and resulting in water leakage. This affects the normal use and lifespan of the drip irrigation pipes. Therefore, it is necessary to design a corrosion-resistant PE drip irrigation pipe to solve these problems. Utility Model Content

[0019] 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.
[0020] Example 1: Please refer to Figure 1-3 As shown, this utility model provides a corrosion-resistant PE drip pipe, including a pipe body 1, and a protective component is embedded in the inner wall of the pipe body 1.
[0021] The pipe body 1 is mainly made of PE (polyethylene). The pipe body 1 has the characteristics of high strength, corrosion resistance and non-toxicity. The protective parts can protect the pipe body 1 from corrosion and strengthen the pipe body 1, extend the service life of the pipe body 1, and at the same time prevent the pipe body 1 from being corroded by soil, pesticides, fertilizers, etc., and avoid the pipe body 1 from cracking and causing damage and leakage.
[0022] Specifically, the protective components include a protective layer 2 embedded inside the tube body 1, an anti-corrosion layer 3 located inside the tube body 1 and outside the protective layer 2, a thermal insulation layer 4 fitted outside the anti-corrosion layer 3, a reinforcing layer 5 fitted outside the thermal insulation layer 4, a flame-retardant layer 8 fitted outside the reinforcing layer 5, and a nylon layer 9 fitted outside the flame-retardant layer 8.
[0023] In addition, the protective layer 2 is mainly made of polyvinyl chloride (PVC) as a geomembrane, which is acid-resistant, alkali-resistant, and durable. The anti-corrosion layer 3 is mainly made of three-layer polyethylene (3PE), which consists of epoxy powder coating primer, copolymer adhesive layer and polyethylene outer protective layer. It has high insulation resistance, strong adhesion, impact resistance and wear resistance, and is suitable for various harsh environments. The thermal insulation layer 4 is mainly made of polyurethane material, which has excellent thermal insulation performance and low thermal conductivity. The reinforcing layer 5 is mainly made of non-woven fabric and waterproof coating, which improves the corrosion resistance and service strength of the drip pipe.
[0024] The flame-retardant layer 8 is primarily made of rubber-plastic sponge, characterized by its softness, cold resistance, and excellent flame-retardant properties. It is suitable for applications requiring good flame retardancy, preventing damage from high-temperature burning during drip pipe storage or use. The nylon layer 9 is mainly made of nylon resin, a synthetic fiber with excellent physical, chemical, and mechanical properties. It is wear-resistant and suitable for environments containing sand and iron filings. The smooth surface of the nylon layer 9 reduces resistance and prevents rust and scaling.
[0025] More specifically, the inner side of the tube body 1 is provided with a plurality of reinforcing ribs 6 arranged in a circular pattern, the outer side of the tube body 1 is provided with a plurality of grooves 7 arranged in a circular pattern, and the inner side of the protective layer 2 is provided with a plurality of guide grooves 10 arranged in a circular pattern.
[0026] Furthermore, the reinforcing rib 6 mainly consists of steel wire and glass fiber, which can significantly improve the pressure-bearing capacity and impact resistance of the pipe, while also enhancing its corrosion resistance and wear resistance. The flow guide trough 10 can guide the water flow. The groove 7 and the flow guide trough 10 facilitate the deformation and bending of the pipe body 1, which can prevent the pipe body 1 from being dragged and cause damage and extend the service life of the pipe body 1.
[0027] Working principle: First, the flame-retardant layer 8 and the nylon layer 9 protect the tube body 1. The anti-corrosion layer 3 and the heat insulation layer 4 can protect the tube body 1 again. The reinforcing rib 6 can strengthen the protection of the tube body 1 when it is dragged, so as to avoid the tube body 1 from being broken or torn. The groove 7 on the outside of the tube body 1 and the guide groove 10 on the inside can facilitate the deformation and bending of the tube body 1, thus extending the service life of the tube body 1.
[0028] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
