Description

Technical Field

[0001] The utility model provides an oxygen-blocking, antibacterial and corrosion-resistant PPR pipe, and relates to the technical field of PPR pipes. Background Art

[0002] PP-R (polypropylene random) pipe, also known as tripropylene pipe, random copolymer polypropylene pipe or PPR pipe, is a pipe made of random copolymer polypropylene. Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, PPR pipes have the advantages of energy saving and material saving, environmental protection, light weight and high strength, corrosion resistance, long service life, etc., and are widely used in construction, municipal administration, industry and agriculture.

[0003] Since the length of each section of PPR pipe is limited and it cannot be bent during construction, if the pipe is laid over a long distance or has many corners, a large number of joints will be used during construction. The surface of PPR pipe is smooth, and hot-melt socket connection is usually used when making joints. Hot-melt connection has many steps and requires the use of special hot-melt tools, which is troublesome and time-consuming. In addition, although the existing PPR pipe usually has an antibacterial layer on the inside, since the PPR pipe itself does not have oxygen barrier properties and is translucent, once the water flow slows down or the water pipe is not used for a long time and there is still water in the pipe, microorganisms will breed in large numbers, and the antibacterial effect is poor. For this reason, we propose oxygen-barrier, antibacterial and corrosion-resistant PPR pipes. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing PPR pipes are difficult to splice and have poor antibacterial effect.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: an oxygen-blocking, antibacterial and corrosion-resistant PPR pipe, comprising a pipe body, the pipe body comprising a PPR pipe layer, one end of the pipe body is provided with a connecting female end, and the other end is provided with a connecting male head, and a plurality of split structures are also provided on the pipe body, the split structure comprises a secondary connecting thread arranged on the outside of the pipe body and a sheath arranged on the outside of the secondary connecting thread, and the inner side of the PPR pipe layer is provided with a light-blocking layer and an oxygen-blocking layer.

[0006] Preferably, a dividing groove is formed on the tube body near the secondary connecting thread, and the dividing groove is annular.

[0007] Preferably, a rib is fixedly connected to the outer wall of the tube body near the secondary connecting thread, and a plurality of ribs are arranged at equal angles around the circumference of the tube body. A connecting tooth is fixedly connected to one side of the sheath near the rib, and one end of the connecting tooth is fixedly connected to the rib.

[0008] Preferably, a limiting burr having a shape matching that of the dividing groove is fixedly connected to one side of the sheath close to the dividing groove.

[0009] Preferably, the male connector is provided with a main connecting thread, and the inner side of the female connector is provided with an internal thread matching the main connecting thread.

[0010] Preferably, a wear-resistant layer is provided on the outer side of the PPR pipe layer.

[0011] Preferably, the light-blocking layer is arranged between the PPR tube layer and the oxygen-blocking layer, and an antibacterial layer is arranged on the inner side of the oxygen-blocking layer.

[0012] Beneficial effects of the utility model:

[0013] By setting the female end, the male end and the split structure, the pipe body can be directly threaded when splicing, so that hot melting operation is not required, which is more convenient and quick;

[0014] By setting up the light-blocking layer and the oxygen-blocking layer, light and oxygen can be blocked to prevent the growth of microorganisms in the tube. Combined with the antibacterial layer, the antibacterial performance of the tube can be greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Reference Figures 1 to 5The utility model provides an oxygen-blocking, antibacterial, and corrosion-resistant PPR pipe, comprising a pipe body 1, wherein the pipe body 1 comprises, from outside to inside, a wear-resistant layer 10, a PPR pipe layer 11, a light-blocking layer 12, an oxygen-blocking layer 13, and an antibacterial layer 14. Specifically, the wear-resistant layer 10 is used to improve the wear resistance of the surface of the pipe body 1, effectively preventing the pipe body 1 from being severely worn due to friction and collision during use, the light-blocking layer 12 is used to block light, making the pipe body 1 opaque, and the oxygen-blocking layer 13 can block oxygen from entering the inside of the pipe body 1 from the outside, and prevent the growth of microorganisms in the pipe body 1 by blocking light and oxygen. In combination with the use of the antibacterial layer 14, the antibacterial performance of the pipe body 1 is greatly improved.

[0023] It should be noted that the oxygen barrier layer 13 is an EVOH oxygen barrier layer 13 and an adhesive layer is provided between adjacent layers, and the antibacterial layer 14 is a nano silver ion antibacterial layer.

Specifically, when the pipe bodies 1 are spliced ​​with each other, the connecting male end 15 can be directly threadedly connected with the connecting female end 3, or a threaded joint can be used, without the need for hot melt connection, and the operation is convenient and quick.

[0025] Furthermore, if Figure 1 , Figure 2 , Figure 3 As shown, the pipe body 1 is also provided with a plurality of segmentation structures 2, the segmentation structures 2 comprising a secondary connection thread 7 provided on the outside of the pipe body 1 and a sheath 5 sleeved on the outside of the secondary connection thread 7, the pipe body 1 is provided with a segmentation groove 8 near the secondary connection thread 7, and the segmentation groove 8 is annular. Specifically, the segmentation structure 2 is used to cut the pipe body 1, and during cutting, the segmentation groove 8 is used for rapid positioning, and after cutting at the segmentation groove 8, the sheath 5 is removed to expose the secondary connection thread 7, and the secondary connection thread 7 can be connected to an existing threaded joint, or connected to a connecting female end 3 of another pipe body 1, and can be quickly connected through threads without hot melt connection.

[0026] Furthermore, if Figure 2 , Figure 3 As shown, the outer wall of the tube body 1 is fixedly connected with a rib 4 near the secondary connection thread 7, and the rib 4 is arranged at a plurality of equal angles around the tube body 1. The side of the sleeve 5 near the rib 4 is fixedly connected with a connecting tooth 6, and one end of the connecting tooth 6 is fixedly connected to the rib 4. Specifically, the sleeve 5 protects the secondary connection thread 7 to prevent wear, and the connection point between the connecting tooth 6 and the rib 4 is very small. By rotating the sleeve 5 with external force, the connecting tooth 6 and the rib 4 can be twisted off, and the sleeve 5 can be removed.

[0027] Furthermore, if Figure 4 As shown, a limiting burr 9 having a shape matching the dividing groove 8 is fixedly connected to one side of the sheath 5 close to the dividing groove 8. Specifically, the limiting burr 9 is concavely engaged in the dividing groove 8 to limit the sheath 5. When the tube body 1 is cut, the limiting burr 9 is also cut, and the sheath 5 can be removed at this time.
