Description

Technical Field

[0001] The utility model provides a corrosion-resistant and non-scaling PPR pipe, belonging to the technical field of PPR pipes. Background Art

[0002] PPR is the abbreviation of tripropylene glycol. PPR pipe is also called random copolymer polypropylene pipe. It has the advantages of energy saving and material saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, simple construction and maintenance, and long service life. PPR pipe is widely used in construction, municipal, industrial and agricultural fields. PPR pipe is made of random copolymer polypropylene through extrusion into pipes and injection molding into pipe fittings.

[0003] The existing PPR pipe can basically meet the use needs, but there are still some defects: after stopping the transmission of liquid medium, too much liquid medium will inevitably remain in the PPR pipe, and the impurities remaining in the liquid medium are easy to scale and remain on the inner wall of the PPR pipe body, which will inevitably corrode the inner wall of the PPR pipe over a long period of time. Based on this, the utility model provides a corrosion-resistant and non-scaling PPR pipe. Utility Model Content

[0004] The technical problem solved by the utility model is that too much liquid medium remains in the PPR pipe, and the impurities remaining in the liquid medium are easily scaled and retained on the inner wall of the PPR pipe body 1, corroding the inner wall of the PPR pipe.

[0005] In order to solve the technical problem, the technical solution provided by the utility model is: a corrosion-resistant and non-scaling PPR pipe, comprising a PPR pipe body, one end of the PPR pipe body is a water inlet end, and the other end is a water outlet end, a support plate is provided between the inner walls of the PPR pipe body close to the water outlet end, a support seat is provided on the side wall of the support plate close to the water inlet end, the side wall of the support seat is rotatably connected with a rotating rod, a guide cone is provided at the end of the rotating rod, and a guide thread is provided on the outer wall of the guide cone; the PPR pipe body comprises a PPR base layer, and an antibacterial and hydrophobic layer is provided on the inner wall of the PPR base layer.

[0006] Furthermore, the ports of the water inlet and the water outlet are both provided with connecting flanges, and a plurality of mounting holes are provided on the circumference of the connecting flanges.

[0007] Furthermore, the cone head of the guide cone is close to the water inlet end, and the cone head of the guide cone is a blunt circular structure.

[0008] Furthermore, the support seat and the rotating rod are rotatably connected via a bearing.

[0009] Furthermore, the antibacterial hydrophobic layer is a film made of PE material, and nano silver ion antibacterial agent is arranged inside the PE material.

[0010] Furthermore, the thickness of the PPR base layer is 3.5-5.5 mm.

[0011] Beneficial effects of the utility model:

[0012] 1. When conveying liquid medium, the flow rate of liquid medium can be accelerated. On the other hand, when the conveying of liquid medium is stopped, the guide cone in the rotating state can guide the liquid medium, so that the liquid medium retained in the PPR pipe body continues to flow forward, effectively avoiding excessive liquid medium remaining in the PPR pipe body, and then effectively preventing the impurities remaining in the liquid medium from scaling and remaining on the inner wall of the PPR pipe body, so as to avoid corrosion of the inner wall of the PPR pipe body;

[0013] 2. The antibacterial hydrophobic layer can block water and resist bacteria, achieving the function of no oil and no scaling. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Principle of the utility model

[0025] When in use, the liquid medium flows and is transported from the water inlet end 12 to the water outlet end 13. When the flowing liquid medium is transported to the guide cone 5, the flowing liquid medium will continue to flow forward along the guide thread 6 on the guide cone 5. Under the action of the bearing 11, the guide cone 5 can be rotated. On the one hand, when the liquid medium is being transported, the flow rate of the liquid medium can be accelerated. On the other hand, when the liquid medium is stopped from being transported, the guide cone 5 in a rotating state can guide the liquid medium, so that the liquid medium retained in the PPR pipe body 1 continues to flow forward, effectively avoiding excessive liquid medium remaining in the PPR pipe body 1, and thus effectively preventing the impurities remaining in the liquid medium from scaling and being retained on the inner wall of the PPR pipe body 1, so as to avoid corrosion of the inner wall of the PPR pipe body 1.
