If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0025] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0026] See also Figure 1-5 , the utility model provides a technical solution: a PE water supply pipe for enhancing the stability of the water supply pipe, comprising an inner pipe 3;

[0027] The protection component is arranged on the outside of the inner pipe 3, and the protection component includes an outer pipe 1, multiple supporting arc parts 2 and multiple reinforcing ribs 4. One ends of the multiple supporting arc parts 2 are bonded to the inner pipe 3, and the other ends of the multiple supporting arc parts 2 are bonded to the inner side of the outer pipe 1. One ends of the multiple reinforcing ribs 4 are respectively bonded to the corresponding supporting arc parts 2, and the other ends of the multiple reinforcing ribs 4 are bonded to the inner pipe 3.

[0028] A counterweight arc piece 5 is fixedly connected to the surface of the outer pipe 1 , connecting rods 6 are fixedly connected to both sides of the counterweight arc piece 5 , and counterweight balls 7 are fixedly connected to the other ends of the two connecting rods 6 .

[0029] The inner pipe 3 is composed of an inner pipe outer layer 8, an inner pipe interlayer 9 and an inner pipe inner layer 10. The inner pipe interlayer 9 is fixed to the outside of the inner pipe inner layer 10, and the inner pipe outer layer 8 is fixed to the outside of the inner pipe interlayer 9. The inner pipe outer layer 8 is composed of polyethylene, which has the ability to withstand erosion by various corrosive media and has good corrosion resistance.

[0030] The inner pipe interlayer 9 is an adhesive layer, which is used to adhere the inner pipe outer layer 8 and the inner pipe inner layer 10 .

[0031] The inner layer 10 of the inner pipe is an epoxy powder base layer with corrosion resistance. The coating can withstand corrosion from strong acids, alkalis, and salts, and has good anti-corrosion properties and wear resistance. The coating formed after the epoxy powder is cured has high wear resistance and can effectively resist wear and scratches in daily use. The epoxy powder has excellent adhesion and can adhere tightly to the surface of objects to form a solid protective layer. The epoxy powder coating is 100% solid for the inner layer of the inner pipe, is solvent-free, and pollution-free.

[0032] The outer pipe 1 is composed of a wear-resistant layer 11 and a PE layer 12. The wear-resistant layer 11 is fixed on the outside of the PE layer 12. The wear-resistant layer 11 is composed of polyhexamethylene adipamide, which has high mechanical strength and hardness, great rigidity and good wear resistance.

[0033] The material of the PE layer 12 is consistent with the material of the inner pipe outer layer 8 .

[0034] By providing the outer pipe 1, the supporting arc member 2 and the reinforcing ribs 4 in the protection assembly, when subjected to external impact, the outer pipe 1 can initially protect the inner pipe 3, and the multiple supporting arc members 2 can mitigate the impact on the whole, while the multiple reinforcing ribs 4 can enhance the resistance strength when subjected to radial impact, that is, reduce the possibility of deformation of the supporting arc member 2 due to impact, thereby mitigating the impact force on the outer pipe 1, thereby protecting the inner pipe 3, that is, improving the safety of the inner pipe 3.

[0035] Since the outer pipe 1 is often not arranged along the central axis when subjected to external impact, that is, when the outer pipe 1 is impacted, it is possible to rotate, and the rotation of the outer pipe 1 will also destroy the air tightness of the entire pipe, causing a safety accident. By providing a counterweight arc 5, counterweight balls 7 are provided on both sides of the counterweight arc 5, and the counterweight balls 7 are symmetrically distributed on the counterweight arc 5, the overall weight of the outer pipe 1 can be enhanced. When there is a torque on the outer pipe 1, the counterweight balls 7 at both ends of the counterweight arc 5 can quickly balance the torque, thereby reducing the possibility of rotation of the outer pipe 1, that is, improving the safety of the outer pipe 1 when in use.

[0036] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
