Description

Technical Field

[0001] The invention relates to the technical field of polyethylene water supply pipes, in particular to a rare earth antibacterial PE water supply pipe. Background Art

[0002] PE water supply pipes are made of polyethylene and other materials. Due to their high strength, corrosion resistance, and non-toxicity, they are widely used in the field of water supply pipe manufacturing. Because PE water supply pipes will not rust, they have good applicability and are often used in the fields of chemistry and construction. However, the existing PE water supply pipes have some shortcomings, such as: Application number: CN202210725998.6 An antibacterial and anti-cracking PE water supply pipe and a preparation method thereof. The PE water supply pipe can utilize the expansion and contraction of the PE corrugated belt to expand the internal space of the water supply inner pipe, thereby preventing the water supply inner pipe from being ruptured due to excessive expansion pressure. However, in actual use, the PE water supply pipe is difficult to support the inside of the water supply pipe, which may cause the water pipe to be deformed due to external pressure or strong internal water pressure, thereby reducing the durability of the equipment.

[0003] Therefore, we proposed a rare earth antibacterial PE water supply pipe to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a rare earth antibacterial PE water supply pipe to solve the problem raised in the above background technology that most PE water supply pipes on the market are difficult to support the inside of the water supply pipes, which may cause the water pipes to be deformed by external pressure or strong internal water pressure, thereby reducing the durability of the equipment.

[0005] To achieve the above object, the present invention provides the following technical solution: a rare earth antibacterial PE water supply pipe, comprising a pipe body and a fixing seat arranged below the pipe body; the bottom of the pipe body is fixedly connected to the fixing seat, and a connecting mechanism is provided at the right end of the pipe body, and the pipe body is connected to another group of pipe bodies through the connecting mechanism; The right end of the pipeline body is connected with a fixing sleeve, and the fixing sleeve fixes the pipeline body, and the right end of the fixing sleeve is fixedly connected to the fixing seat, and the right end of the fixing seat is fixedly connected to the connecting mechanism.

[0006] The bottom side of the pipe body can be fixed by the fixing seat at the bottom of the pipe body, and when the top of the pipe body is subjected to pressure, the pipe body can be buffered by the fixing seat. At the same time, since the pipe bodies are interconnected by connecting mechanisms, the connection between the two groups of pipes can be protected by the connecting mechanism, so that when the pipe body itself is subjected to pressure, it can be buffered by the pipe body itself and the fixing seat, and when the connection is subjected to pressure, it can be protected by the connecting mechanism.

[0007] As a preferred technical solution of the present invention, the pipeline body includes an antibacterial tube layer, and a fixed tube is connected to the outside of the antibacterial tube layer, and a support damper is connected to the outside of the fixed tube, and a support pipe sheet is connected to the outside of the support damper, and a bonding pipe sheet is connected to the outside of the support pipe sheet, and a buffer layer is provided between the bonding pipe sheet and the fixed tube; An anti-aging tube layer is connected to the outside of the fitted tube piece, and the left end of the anti-aging tube layer is fixedly connected to the fixed sleeve, and the antibacterial tube layer, the fixed tube and the left end of the fitted tube piece are all fixedly connected to the fixed sleeve.

[0008] The adoption of the above technical solution ensures that after the gas and liquid enter the pipeline body, the bacteria in the gas and liquid will not be adsorbed inside the pipeline body to damage the pipeline, thereby increasing the durability of the equipment, and through the setting of support damping and support pipe segments, when the outside or inside of the pipeline body is subjected to pressure, the pressure can be transmitted to the support damping, and the pressure is transmitted to the support pipe segments and the buffer layer through the support damping for pressure buffering, thereby increasing the antibacterial properties of the inner wall of the pipeline body and the pressure resistance of the middle layer of the pipeline.

[0009] As a preferred technical solution of the present invention, the bottom of the anti-aging tube layer is fitted with the fixed seat, and the fixed seat includes a fitting seat, and a fixed bottom cover is connected to the left end of the fitting seat, a fixing ring is connected to the top of the fixed bottom cover, and the fixing ring is fixedly connected to the fixing sleeve, and a first connecting bolt is provided at the bottom of the fixed bottom cover.

[0013] As a preferred technical solution of the present invention, a bonding film is provided inside the first flange and the second flange, and the outer side of the antibacterial tube layer inside the pipeline body is fixedly connected to the first flange and the second flange through the bonding film.

[0014] The above technical solution enables the antibacterial tube layer to be connected to the first flange and the second flange through the bonding film when being bonded to the antibacterial tube layer, thereby making the first flange and the second flange more firmly connected to the antibacterial tube layer and increasing the sealing performance of the antibacterial tube layer when connected to the connecting mechanism.

[0015] As a preferred technical solution of the present invention, the buffer layer inside the pipe body is made of rubber particles, and the buffer layer is located outside the support damping, and the buffer layer is elastic.
