Description

Technical Field

[0001] The utility model belongs to the technical field of polyethylene pipes, and particularly relates to a high-strength heat-resistant polyethylene pipe. Background Technique

[0002] The polyethylene pipe is also called PE pipe. PE resin is polymerized from the monomer ethylene. Due to different polymerization reaction conditions such as pressure and temperature during polymerization, resins with different densities can be obtained. Therefore, there are also high-density polyethylene, medium-density polyethylene, and low-density polyethylene. When processing different types of PE pipes, according to different application conditions and different resin grades selected, the requirements for the extruder and the die are also different.

[0003] The traditional polyethylene pipe often has limited heat resistance. When the pipe fitting bears more heat, the pipe fitting may become soft or deformed, resulting in a decrease in the strength or a shortening of the service life of the pipe fitting. Therefore, a high-strength heat-resistant polyethylene pipe is needed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-strength heat-resistant polyethylene pipe to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A high-strength heat-resistant polyethylene pipe, including a polyethylene pipe fitting, an outer metal pipe layer is arranged on the outside of the polyethylene pipe fitting, a plurality of through holes are opened on the metal pipe layer, a plurality of plate frames are fixedly connected to the outside of the metal pipe layer, a ceramic pipe layer is sleeved on the outside of the metal pipe layer, the space between the ceramic pipe layer and the metal pipe layer is a heat insulation cavity, a plurality of insertion holes are opened on the outside of the ceramic pipe layer, one end of each plate frame is inserted and fixed on the ceramic pipe layer through the insertion hole respectively, a heat dissipation plate is fixedly arranged through each plate frame, and the centripetal sides of the plurality of heat dissipation plates are fixedly connected to the metal pipe layer.

[0006] When the external environment is heated, the ceramic tube layer will first come into contact with the heat and isolate it. Due to the arrangement between the metal tube layer and the ceramic tube layer, even if the heat on the ceramic tube layer is too high, it is difficult to directly transfer to the surface of the polyethylene pipe fitting through the heat insulation cavity. As a result, the polyethylene pipe fitting has a strong heat insulation effect. In addition, due to the multiple plate frames and heat dissipation plates provided on the metal tube layer, even if the temperature on the surface of the polyethylene pipe fitting is too high, it is helpful to transfer and dissipate heat to the outside through the heat dissipation plates. During this period, due to the multiple through holes provided on the metal tube layer, the polyethylene pipe fitting can dissipate local heat into the heat insulation cavity, which helps to ensure the temperature balance in the heat insulation cavity, and further helps to ensure a strong heat dissipation and temperature equalization effect. In summary, it helps to improve the overall heat resistance of the polyethylene pipe fitting, thereby helping to ensure the service life of the polyethylene pipe fitting and enhance the use strength of the polyethylene pipe fitting.

[0007] As a preferred embodiment, heat dissipation openings are provided on both sides of each of the plate frames.

[0008] As a preferred embodiment, each of the heat dissipation openings is located outside the ceramic tube layer.

[0009] As a preferred embodiment, each of the heat dissipation plates is in contact with the outside through the heat dissipation openings.

[0010] As a preferred embodiment, a plurality of heat dissipation patterns are provided on each of the heat dissipation plates.

[0011] As a preferred embodiment, the through holes are arranged horizontally with respect to the overall polyethylene pipe fitting.

[0012] By providing a plurality of heat dissipation patterns on each of the heat dissipation plates, when the heat dissipation plate dissipates heat to the outside, the arrangement of the heat dissipation patterns helps to enhance its heat dissipation effect. In addition, due to the relative horizontal arrangement of the through holes, the connection structure between the metal tube layer and the plate frame is relatively stable, which further helps to ensure the stability of the overall structure of the polyethylene pipe fitting.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] The utility model, through the ceramic tube layer, when the external environment is heated, the ceramic tube layer will first contact the heat and isolate the heat to the outside, and because it is arranged between the metal tube layer and the ceramic tube layer, even if the heat on the ceramic tube layer is too high, it is difficult to directly transfer to the surface of the polyethylene pipe fittings through the insulation cavity, thereby making the polyethylene pipe fittings have a stronger thermal insulation effect. In addition, because a plurality of plate frames and heat dissipation plates are arranged on the metal tube layer, even if the temperature on the surface of the polyethylene pipe fittings is too high, it is helpful to transfer the heat to the outside through the heat dissipation plates. During this period, because a plurality of through holes are arranged on the metal tube layer, the polyethylene pipe fittings can dissipate local heat to the insulation cavity, which helps to ensure the temperature balance in the insulation cavity, and then helps to ensure a stronger heat dissipation and temperature uniformity effect. In summary, it helps to improve the overall heat resistance of the polyethylene pipe fittings, thereby helping to ensure the service life of the polyethylene pipe fittings and enhance the use strength of the polyethylene pipe fittings.

[0015] The utility model provides a plurality of heat dissipation patterns on each of the heat dissipation plates, so that when the heat dissipation plates dissipate heat to the outside, the arrangement of the heat dissipation patterns helps to enhance the heat dissipation effect. In addition, the through holes are relatively horizontally arranged, so that the connection structure between the metal pipe layer and the plate frame is more stable, which helps to ensure the stability of the overall structure of the polyethylene pipe fittings.

In addition, since a plurality of plate frames 7 and heat dissipation plates 8 are arranged on the metal tube layer 2, even if the temperature on the surface of the polyethylene pipe fitting 1 is too high, it is helpful to transfer the heat to the outside through the heat dissipation plate 8. During this period, since a plurality of through holes 3 are arranged on the metal tube layer 2, the polyethylene pipe fitting 1 can dissipate local heat to the insulation cavity 5, which helps to ensure the temperature balance in the insulation cavity 5, and further helps to ensure that 1 has a stronger heat dissipation and temperature uniformity effect. In summary, it helps to improve the overall heat resistance of the polyethylene pipe fitting 1, thereby helping to ensure the service life of the polyethylene pipe fitting 1 and enhance the use strength of the polyethylene pipe fitting 1.

In addition, due to the relatively horizontal setting of the through hole 3, the connection structure between the metal pipe layer 2 and the plate frame 7 is relatively stable, which helps to ensure the stability of the overall structure of the polyethylene pipe fitting 1.

[0031] The working principle and usage process of the present utility model are as follows: First, in the ceramic pipe layer 4, when the external environment is heated, the ceramic pipe layer 4 will first contact the heat and isolate it.
