[0024] To facilitate a better understanding of this utility model, the following examples are provided in conjunction with the accompanying drawings. These examples fall within the protection scope of this utility model, but do not limit the protection scope of this utility model.

[0025] Example 1

[0026] A new type of PE / PVC-O water supply pipe, such as Figures 1-4 As shown, it includes: a first layer 1, which is a ring structure; and a second layer 2, which is a ring structure and is disposed on the outer surface of the first layer 1; the first layer 1 is made of PVC-O material; and the second layer 2 is made of HDPE material.

[0027] The water supply pipe has two layers: the first layer is made of PVC-O material and the second layer is made of PE material. The PVC-O material is inside the pipe and the PE material is outside the pipe. When used as a water supply pipe, it fully combines the advantages of the two materials, and can have the characteristics of high strength and high toughness on the basis of PE pipe, while the production cost is relatively controllable.

[0028] PE / PVC-O water supply pipes are composite water supply pipes that can be used in municipal water, residential, industrial, and agricultural water supply applications.

[0029] Example 2

[0030] like Figures 1-4 As shown, the PE / PVC-O water supply pipe also includes: a reinforcing rib 3, one end of which is provided on the outer surface of the first layer 1, and the other end is connected to the second layer 2; there are several reinforcing ribs 3, which are distributed at intervals on the outer surface of the first layer 1.

[0031] like Figures 1-4 As shown, the reinforcing rib 3 is a long strip with the same length as the pipe, and it is a protrusion facing the second layer 2 with a larger bottom and a smaller top.

[0032] likeFigures 1-4 As shown, the height of the reinforcing rib 3 is 0.2-0.5 times the thickness of the pipe; each reinforcing rib 3 is symmetrically arranged around the centerline of the pipe.

[0033] like Figures 1-4 As shown, the PE / PVC-O water supply pipe also includes: a buffer layer 4, which is located in the area between the first layer 1 and the second layer 2; the outer side of the reinforcing rib 3 can be wrapped by the buffer layer 4.

[0034] Several reinforcing ribs are provided, and they can be symmetrically arranged with the center line of the longitudinal section of the PE / PVC-O water supply pipe as the axis. The symmetrical arrangement of the reinforcing ribs can enable the water supply pipe to better withstand the external force on the circumference. The number of reinforcing ribs can be reasonably set according to the pipe diameter, usage requirements, etc., such as setting 8 or 10 ribs.

[0035] The longitudinal interface of the reinforcing rib has a convex structure facing the second layer, with one end larger than the first layer and the other end smaller than the second layer, which provides better stability in use.

[0036] The buffer layer can completely enclose the reinforcing ribs, creating a buffer layer between the reinforcing ribs and the second layer, which can reduce the impact of external forces on the reinforcing ribs; the buffer layer can be made of a slightly softer material, which can prevent the material from being too rigid and breaking when the water pipe is subjected to external forces, thus improving its service life.

[0037] Example 3

[0038] like Figures 1-4 As shown, the PE / PVC-O water supply pipe also includes: a first reinforcing mesh 5, which is a ring structure and is located between the second layer 2 and the buffer layer 4; the length of the first reinforcing mesh 5 is the same as the length of the pipe.

[0039] like Figures 1-4 As shown, the PE / PVC-O water supply pipe also includes: a second reinforcing mesh 6, which is a ring structure, with one side located on the outer surface of the first layer 1 and the other side connected to the bottom of the reinforcing rib 3; the length of the second reinforcing mesh 6 is the same as the length of the pipe.

[0040] The first reinforcing mesh is designed as a ring structure, tightly wrapped around the outside of the buffer layer, which can effectively enhance the pressure resistance of the pipe; moreover, the ring structure can make the external force on the water supply pipe more uniform, while the reinforcing ribs set on the outer surface of the first layer can provide support for the first reinforcing mesh and improve its pressure resistance.

[0041] The second reinforcing net also adopts a ring structure, and is wrapped outside the first reinforcing net, and the bottom of the reinforcing rib is arranged on the second reinforcing net; the second reinforcing net and the first reinforcing net are concentric tubular structures, and the two are combined to form a net-shaped area, and the reinforcing rib and the buffer layer are arranged in the area; in this way, the compression resistance of the water supply pipe is further improved, and the durability of the water supply pipe in complex environments is enhanced.

[0042] The first reinforcing net can be made of an existing plastic material, and the second reinforcing net can be made of an existing metal material; the second reinforcing net is made of a metal material, can provide better support for the reinforcing rib, and protects the first layer made of the PVC-O material, so that the first layer can still be normally used when the second layer is damaged by external force, and water flow waste caused by pipe rupture is avoided.

[0043] In actual use, the PE / PVC-O water supply pipe has good compression resistance, can resist pressure from water pressure, construction and other aspects, avoids pipe damage caused by excessive pressure, and solves problems such as water leakage and water stop, and ensures normal operation of the water supply pipe and water supply safety.

[0044] The first layer, the second layer, the reinforcing rib, the buffer layer, the first reinforcing net, the second reinforcing net and other layers in the application are bonded by using a bonding layer, and the bonding layer is an existing adhesive.

[0045] It should be noted that, in this text, relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment. Without more limitations, the statement "including a limited element" does not exclude the existence of another identical element in the process, method, article or equipment including the element.

[0046] The above is only a preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
