Description

Technical Field

[0001] This utility model relates to the field of PE pipe technology, specifically to a rodent-resistant, tensile-resistant, high-strength composite PE pipe. Background Technology

[0002] In the installation of water purifiers and water dispensers, PE water pipes are a very important component, used as water supply pipelines to connect the water purifier and the water dispenser.

[0003] In the existing technology, there are usually two methods for laying PE water pipes: pre-buried installation and exposed installation. When pre-buried installation is used, the existing PE water pipes have relatively low tensile strength. Therefore, when the water pressure is too high, the PE water pipes are prone to damage and leakage, resulting in a large workload for repair and replacement. When exposed installation is used, the PE water pipes contain water, which makes them easy targets for rats in search of water. This can directly cause the PE water pipes to be chewed and damaged. Utility Model Content

[0004] The purpose of this utility model is to provide a rodent-proof, tensile-resistant, high-strength composite PE pipe to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a rodent-resistant, tensile-resistant, high-strength composite PE pipe, comprising a PE pipe body, the outer periphery of which is covered with an outer PVC protective layer and an inner glass fiber protective layer, which are used to enhance the tensile strength of the PE pipe body and provide external protection against biting by means of the PVC protective layer and the glass fiber protective layer.

[0007] Preferably, the PE pipe body is a two-point hose or a three-point hose.

[0008] Preferably, the glass fiber protective layer is wrapped tightly around the outside of the PE pipe body.

[0009] Preferably, the glass fiber protective layer has at least two winding layers.

[0010] Preferably, the PVC protective layer is coated and adhered to the outside of the glass fiber protective layer by a colloid spraying method.

[0011] Preferably, the thickness of the PVC protective layer is between 1 mm and 2 mm.

[0012] Preferably, the outer surface of the PVC protective layer is coated with a rodent-repellent coating to prevent rodent bites.

[0013] Preferably, the rodent-repellent coating is Caritys rodent-proof coating.

[0014] Preferably, the coating thickness of the rodent-repellent coating is not less than 0.5 mm.

[0015] The aforementioned rodent-resistant, tensile-resistant, high-strength composite PE pipe, in its practical application, features an outer PVC protective layer and an inner fiberglass protective layer surrounding the PE pipe body. These layers enhance the tensile strength of the PE pipe, ensuring it can withstand high water pressure without damage or leakage, thus extending its reliable service life. Simultaneously, they provide external protection against rodent damage from chewing. Furthermore, the fiberglass protective layer is wrapped and secured using a winding method. On the outside of the PE pipe body, the PVC protective layer can be wrapped and adhered to the outside of the glass fiber protective layer by means of colloid spraying. The method of wrapping the PVC protective layer and the glass fiber protective layer on the outside of the PE pipe body is simple and easy to implement, which is conducive to efficient mass production. Furthermore, since the outside of the PVC protective layer is coated with a rodent-repellent coating that has a rodent-repellent effect, and the rodent-repellent coating is Caritys rodent-repellent paint, the rodent-repellent coating can fundamentally prevent rats from avoiding the PE pipe body, thereby further enhancing the rodent-repellent effect of the PE pipe body.

[0016] The beneficial effects are as follows: 1. This utility model has an outer PVC protective layer and an inner glass fiber protective layer wrapped around the PE pipe body. With the help of the PVC protective layer and the glass fiber protective layer, the tensile strength of the PE pipe body can be enhanced, ensuring that it will not be damaged or leaked when subjected to large water pressure, which is conducive to extending the reliable service life. At the same time, it can also protect the PE pipe body from external gnawing and prevent damage from rats.

[0017] 2. By using a winding method, the glass fiber protective layer can be wrapped around the outside of the PE pipe body. At the same time, by using an adhesive spraying method, the PVC protective layer can be wrapped and adhered to the outside of the glass fiber protective layer. The method of wrapping the PVC protective layer and the glass fiber protective layer on the outside of the PE pipe body is simple and easy to achieve, which is conducive to efficient mass production.

[0018] 3. The outer coating of the PVC protective layer is covered with a rodent-repellent coating to prevent rodent bites. The rodent-repellent coating is Caritys rodent-repellent paint. With the help of the rodent-repellent coating, rats can be fundamentally prevented from avoiding the PE pipe body, thereby further enhancing the rodent-repellent effect of the PE pipe body.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] See Figures 1-5As shown, this utility model provides a rodent-resistant, tensile-resistant, high-strength composite PE pipe, including a PE pipe body 4. The PE pipe body 4 is surrounded by an outer PVC protective layer 2 and an inner glass fiber protective layer 3. The PVC protective layer 2 and the glass fiber protective layer 3 are used to enhance the tensile strength of the PE pipe body 4 and to provide external protection against rodent bites. The purpose of this design is that, firstly, the PVC protective layer 2 and the glass fiber protective layer 3 can enhance the tensile strength of the PE pipe body 4, ensuring that it can withstand high water pressure without damage or leakage, thus extending its reliable service life. At the same time, it can also provide external protection against rodent bites, preventing damage from rodents.

[0029] See Figures 1-4 As shown, the following optimizations have been made to this application. Specifically, the PE pipe body 4 is a two-point or three-point flexible hose, so that the PE pipe body 4 can meet the usage requirements of water purifier pipeline layout. Optionally, the glass fiber protective layer 3 is tightly wound around the outside of the PE pipe body 4, and the PVC protective layer 2 is coated and adhered to the outside of the glass fiber protective layer 3 by adhesive spraying. Preferably, both the tight winding and adhesive spraying are completed using corresponding equipment. With this setup, the glass fiber protective layer 3 can be wrapped around the outside of the PE pipe body 4 by winding, and the PVC protective layer 2 can be coated and adhered to the outside of the glass fiber protective layer 3 by adhesive spraying. The method of covering the PVC protective layer 2 and the glass fiber protective layer 3 on the outside of the PE pipe body 4 is simple and easy to implement.

[0030] See Figures 1-5 As shown, the fiberglass protective layer 3 has at least two winding layers, and the thickness of the PVC protective layer 2 ranges from 1mm to 2mm. This arrangement ensures that the fiberglass protective layer 3 provides good and stable tensile reinforcement, while also ensuring that the thickness of the PVC protective layer 2 provides good protection against chewing damage. The PVC protective layer 2 is coated with a rodent-repellent coating 1, which is Caritys rodent-repellent paint. This arrangement effectively prevents rats from avoiding the PE pipe body 4, further enhancing the rodent-repellent effect of the PE pipe body 4. Optionally, the rodent-repellent coating 1 has a coating thickness of not less than 0.5mm to ensure that its design thickness meets usage requirements and avoids insufficient rodent-repellent effectiveness due to excessive thinness.

[0031] With the above structure, in practical applications, the PE pipe body 4 is surrounded by an outer PVC protective layer 2 and an inner fiberglass protective layer 3. These layers enhance the tensile strength of the PE pipe body 4, ensuring it can withstand high water pressure without damage or leakage, thus extending its reliable service life. They also provide external protection against rodent damage. Furthermore, the fiberglass protective layer 3 is wrapped around the PE pipe body using a winding method. On the outside of 4, the PVC protective layer 2 can be wrapped and adhered to the outside of the glass fiber protective layer 3 by means of colloid spraying. The method of wrapping the PVC protective layer 2 and the glass fiber protective layer 3 on the outside of the PE pipe body 4 is simple and easy to implement, which is conducive to efficient mass production. Furthermore, since the outside of the PVC protective layer 2 is coated with a rodent-repellent coating 1, which has the effect of preventing rodent bites, and the rodent-repellent coating 1 is Caritys rodent-repellent coating, the rodent-repellent coating 1 can fundamentally prevent rats from avoiding the PE pipe body 4, thereby further enhancing the rodent-repellent effect of the PE pipe body 4.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
