In addition, the polyethylene pipeline also has good impact resistance and wear resistance, and can resist the direct pressure of heavy objects without breaking.

[0004] In the above scheme, the liquid is treated by nano zinc oxide, which still has the following shortcomings: nano zinc oxide may be directly soaked in the flowing liquid in the pipeline, and the nano zinc oxide may be eroded with the scouring of the flowing liquid, reducing the service life of nano zinc oxide in antibacterial. UTILITY MODEL CONTENT

[0005] The utility model aims at providing an antibacterial polyethylene pipe for water supply to solve the problem that the nano zinc oxide may be eroded with the scouring of the flowing liquid, reducing the service life of nano zinc oxide in antibacterial.

[0006] In order to achieve the above utility model purpose, the utility model adopts the following technical scheme: an antibacterial polyethylene pipe for water supply, comprising a pipeline outer layer, the inner wall surface of the pipeline outer layer is fixed with a temperature resistant layer, the inner wall surface of the temperature resistant layer is fixed with a reinforcing layer, the inner wall surface of the reinforcing layer is fixed with an antibacterial layer, the inner wall surface of the antibacterial layer is fixed with a permeation layer, the antibacterial layer is made of zinc oxide, and the permeation layer is made of polypropylene material.

[0007] Preferably, the pipeline outer layer is made of polyethylene, the temperature resistant layer is made of ceramic, and the reinforcing layer is made of polyethylene.

[0008] Preferably, the surface of one end of the pipeline outer layer is fixed with a threaded pipe, the surface of the other end of the pipeline outer layer is fixed with a fixed pipe, a connecting pipe is threadedly connected on the threaded pipe, and the surface of the connecting pipe is fixed with a plurality of anti-skid strips.

[0009] Preferably, the inside of the threaded pipe is detachably provided with a mounting ring, and the inside of the mounting ring is fixed with a filter plate.

[0010] Preferably, the inner wall surface of the threaded pipe is fixed with a plurality of limiting plates, and the surface of the mounting ring is provided with a plurality of limiting openings, and the limiting plates and the limiting openings are slidably arranged.

[0011] Preferably, the inner wall surface of the permeation layer is fixed with a plurality of support columns, and adjacent two support columns are arranged at 90 degrees.

[0012] Compared with the prior art, the water supply antibacterial polyethylene pipe has the following beneficial effects:

[0013] I. The outer layer and the reinforcing layer of the polyethylene support not only increase the internal corrosion performance of the pipeline, but also increase the wear resistance of the pipeline, which makes the pipeline perform well in the fields of chemical industry, chemical fiber, food, etc. Moreover, the high wear resistance can increase the service life of the pipeline in use. In the process of conveying liquid, the antibacterial layer made of zinc oxide releases zinc ions, which then penetrate into the conveyed liquid through the permeation layer. The zinc ions can destroy the cell membrane of microorganisms in the liquid, thereby inhibiting the growth and reproduction of the microorganisms. The antibacterial layer is separated from the liquid by a layer of permeation layer, which avoids the erosion of the antibacterial layer caused by water flow, thereby increasing the service life of the antibacterial layer.

[0014] II. When connecting two sections of pipeline, the worker will set the threaded pipe on the surface of the other section of pipeline and adhere to one side of the fixed pipe. The worker can install or remove the mounting ring into or from the pipeline when assembling or disassembling two sections of pipeline, so as to replace the blocked filter plate in time. During the use of the pipeline, the pipeline may be directly installed on the ground. When the pipeline is stepped on and bears pressure, the support column can increase the pressure resistance of the pipeline in use. BRIEF DESCRIPTION OF DRAWINGS
