Description

Technical Field

[0001] This utility model relates to the field of MPP pipe technology, specifically a high flame retardant and high heat resistant MPP pipe. Background Technology

[0002] MPP uses modified polypropylene as the main raw material. It is a construction project that does not require a lot of dredging, excavation and road surface damage to lay pipelines and cables in special sections such as roads, railways, buildings and riverbeds. Compared with the traditional trenching and burying method, trenchless power pipe engineering is more in line with current environmental protection requirements and eliminates the nuisance factors such as dust and traffic congestion caused by traditional construction.

[0003] Some existing MPP pipes are single-pipe designs with poor flame retardancy and heat insulation. They are not only easily damaged by external fire sources, thus reducing the service life of the MPP pipes, but also cannot block external heat. External heat can easily affect the transmission of cables inside the pipes, thus significantly reducing the practicality of MPP pipes. Therefore, those skilled in the art have provided a highly flame-retardant and highly heat-resistant MPP pipe to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a highly flame-retardant and highly heat-resistant MPP pipe to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high flame-retardant and high heat-resistant MPP pipe includes an MPP round pipe body, the MPP round pipe body including an inner pipe, a first flame-retardant layer, a second flame-retardant layer, a third flame-retardant layer and a wear-resistant layer, a first connecting plate installed on the outer surface of the MPP round pipe body, a second connecting plate installed on the outer surface of the MPP round pipe body, an annular groove opened on the outer surface of the first connecting plate, and an annular clamping plate installed on the outer surface of the second connecting plate.

[0007] As a further improvement of this utility model: the inner wall of the annular slot is provided with a first positioning hole arranged in a ring, and the annular card plate is adapted to the annular slot.

[0008] As a further improvement of this utility model: the outer surface of the annular card plate is provided with second positioning holes arranged in a ring, and the inner wall of each second positioning hole is threaded with a positioning screw.

[0009] As a further improvement of this utility model: the inner wall of the wear-resistant layer is connected to the first flame-retardant layer, which is made of polytetrafluoroethylene.

[0010] As a further embodiment of this utility model: the inner wall of the first flame-retardant layer is connected to the second flame-retardant layer, and the second flame-retardant layer is made of aluminum disulfide plastic.

[0011] As a further embodiment of this utility model: the inner wall of the second flame-retardant layer is connected to the third flame-retardant layer, wherein the third flame-retardant layer is fireproof cotton.

[0012] As a further embodiment of this utility model: the inner wall of the third flame-retardant layer is connected to the insulating layer, and the inner wall of the insulating layer is connected to the inner tube.

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

[0014] This highly flame-retardant and heat-resistant MPP pipe, through the setting of a first flame-retardant layer, a second flame-retardant layer, a third flame-retardant layer, and a wear-resistant layer, not only makes the MPP round pipe body wear-resistant, but also improves the flame-retardant and heat insulation effects of the MPP round pipe body. The setting of an insulation layer makes the MPP round pipe body insulating. Through the setting of a first connecting plate, a first positioning hole, an annular groove, a second connecting plate, a positioning screw, an annular clamping plate, and a second positioning hole, it not only facilitates the splicing of the MPP round pipe body, thereby greatly increasing the construction efficiency, but also makes the connection of the MPP round pipe body more stable.

[0022] Please see Figures 1-4 In this embodiment of the present invention, a high flame-retardant and high heat-resistant MPP pipe includes an MPP round pipe body 1. The MPP round pipe body 1 includes an inner pipe 101, a first flame-retardant layer 105, a second flame-retardant layer 104, a third flame-retardant layer 103, and a wear-resistant layer 106. A first connecting plate 2 and a second connecting plate 5 are installed on the outer surface of the MPP round pipe body 1. An annular groove 4 is opened on the outer surface of the first connecting plate 2, and an annular clamping plate 7 is installed on the outer surface of the second connecting plate 5. This not only improves the heat insulation and flame-retardant effect of the MPP round pipe body 1, but also facilitates the splicing of the MPP round pipe body 1. This solves the problem mentioned in the background art that some existing MPP pipes use single pipes, have poor flame-retardant and heat insulation effects, are easily damaged by external fire sources, thus reducing the service life of the MPP pipe, and cannot block external heat. External heat can easily affect the transmission operation of cables inside the pipe, thus greatly reducing the practicality of the MPP pipe.

[0023] The inner wall of the annular slot 4 is provided with first positioning holes 3 arranged in a ring. The annular plate 7 is adapted to the annular slot 4. The outer surface of the annular plate 7 is provided with second positioning holes 8 arranged in a ring. The inner wall of each second positioning hole 8 is threaded with a positioning screw 6. This not only makes it convenient for people to splice the MPP round tube body 1, but also greatly increases the stability of the MPP round tube body 1.

[0024] The inner wall of the wear-resistant layer 106 is connected to the first flame-retardant layer 105, which is made of polytetrafluoroethylene. The inner wall of the first flame-retardant layer 105 is connected to the second flame-retardant layer 104, which is made of aluminum disulfide plastic. The inner wall of the second flame-retardant layer 104 is connected to the third flame-retardant layer 103, which is made of fireproof cotton. The inner wall of the third flame-retardant layer 103 is connected to the insulation layer 102, which is connected to the inner tube 101. This not only improves the heat insulation and flame-retardant effect of the MPP round tube body 1, but also prevents the cable from causing harm to construction personnel in the event of leakage.

[0025] The working principle of this utility model is as follows: During the construction process, the construction personnel can insert the annular card plate 7 into the annular card slot 4 and use the positioning screw 6 to position it. The first flame retardant layer 105, the second flame retardant layer 104 and the third flame retardant layer 103 can prevent external fire sources and heat from damaging the MPP round tube body 1 and the cable. The wear-resistant layer 106 can prevent wear on the MPP round tube body 1 during the construction process. The insulation layer 102 can prevent injury to the construction personnel in the event of cable leakage.
