Description

Technical Field

[0001] This utility model belongs to the field of PVC pipe technology, and in particular relates to a high-strength, pressure-resistant PVC pipe. Background Technology

[0002] Polyvinyl chloride (PVC) pipes, widely used in construction, municipal, industrial, and agricultural fields, play an irreplaceable role in water supply and drainage systems, cable protection conduits, irrigation pipelines, and chemical fluid transportation due to their advantages such as light weight, corrosion resistance, low cost, and convenient installation. For example, in building drainage systems, PVC pipes can effectively resist the erosion of sewage and chemicals, ensuring long-term stable operation; in municipal water supply and drainage projects, their lightweight nature significantly reduces installation difficulty and transportation costs; and in agricultural irrigation, PVC pipes have become the preferred piping material due to their excellent weather resistance and economy.

[0003] Currently, the connection between two adjacent PVC pipes is generally achieved by welding, which involves melting the pipe joints together using hot melt or chemical solvents. However, existing PVC pipes are prone to deformation and damage during installation due to accidental bumps or external pressure, requiring the replacement of the entire pipe. Since adjacent pipe sections are welded together to form an integrated structure, destructive methods such as cutting are required to remove the weld points and surrounding pipes. After replacing the pipe, re-welding is necessary, making the replacement process complex, time-consuming, and labor-intensive. Utility Model Content

[0009] Optionally, a flexible layer is provided between the heat-resistant layer and the outer layer, the flexible layer being made of an elastic material; a metal mesh layer is provided on the outer surface of the flexible layer near the outer layer.

[0010] Optionally, the outer surface is provided with a wear-resistant coating, which is made of epoxy resin, polyethylene, or polyurethane material.

[0011] Optionally, the fixing buckle includes two sets of first fixing rings and second fixing rings symmetrically distributed vertically; a fixing plate for fixing is provided between the first fixing ring and the second fixing ring on the same side, and the first fixing ring and the second fixing ring are rotatably connected to the fixing plate respectively; a first connecting platform is provided on the other side of the first fixing ring and the second fixing ring; a fixing rod is provided between the two sets of first connecting platforms; one end of the fixing rod is rotatably connected to one of the sets of first connecting platforms, and a threaded locking nut is provided on the other end.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0031] In one embodiment of this utility model, such as Figures 1-6 As shown, a high-strength, pressure-resistant PVC pipe is provided, including a pipe body 10. Both ends of the pipe body 10 are provided with outwardly protruding connecting portions 11, and sealing rings 12 for sealing are provided on the connecting portions 11. The connecting portions 11 are provided with fixing buckles 20 for quick connection of the connecting portions 11 on adjacent sets of pipe bodies 10. One end of the pipe body 10 is provided with a snap-fit ​​portion 17 extending axially along the pipe body 10, and the snap-fit ​​portion 17 is detachably connected to the pipe body 10. The other end is provided with a snap-fit ​​groove 18 corresponding to the snap-fit ​​portion 17, and the snap-fit ​​portion 17 of the front set of pipe bodies 10 can snap into or disengage from the snap-fit ​​groove 18 of the rear set of pipe bodies 10. The pipe body 10 includes an outer layer 32 and an inner layer 31. A reinforcing layer 33 is provided between the outer layer 32 and the inner layer 31. A reinforcing structure 34 is provided between the reinforcing layer 33 and the inner layer 31.

[0032] By setting an outer layer 32, an inner layer 31, a reinforcing layer 33, and a reinforcing structure 34, and by having multiple sets of first reinforcing ribs 341 and second reinforcing ribs 342 in the reinforcing structure 34 distributed at equal intervals between the reinforcing layer 33 and the inner layer 31, and forming a mesh structure through an interlaced distribution, this multi-layered mesh structure with reinforcing ribs greatly improves the overall strength and compressive strength of the pipe body 10, effectively disperses the stress generated by accidental impacts or external pressure, and reduces the possibility of deformation and damage to the pipe body 10.

[0033] By setting the snap-fit ​​part 17 and the snap-fit ​​groove 18, the snap-fit ​​part 17 of the front group of pipe body 10 snaps into the snap-fit ​​groove 18 of the rear group of pipe body 10, thus completing the initial fixation between the two adjacent groups of pipe bodies 10. Then, the first fixing ring 21 and the second fixing ring 22 in the fixing buckle 20 are used for quick fixation and locking. The connection and fixation of adjacent pipe sections can be completed in a short time, so that adjacent pipe sections do not need to be welded to form an integrated structure. At the same time, when it is necessary to replace the pipe, it is only necessary to release the locking of the fixing buckle 20 and detach the snap-fit ​​part 17 from the snap-fit ​​groove 18 to easily disassemble the damaged pipe section. There is no need to use destructive methods such as cutting to remove the welding point and the surrounding pipe body 10, which simplifies the disassembly steps and saves time and manpower.

[0034] Preferably, the reinforcing structure 34 includes a first reinforcing rib 341 and a second reinforcing rib 342. Multiple sets of first reinforcing ribs 341 and second reinforcing ribs 342 are evenly spaced between the reinforcing layer 33 and the inner layer 31, and the first reinforcing ribs 341 and second reinforcing ribs 342 are staggered to form a mesh structure. In this embodiment, the reinforcing layer 33 is made of glass fiber, modified carbon fiber, or high-strength steel wire, and the first reinforcing ribs 341 and second reinforcing ribs 342 are made of steel wire, polyester fiber, aramid fiber, or glass fiber bundles. The materials of the first reinforcing ribs 341 and second reinforcing ribs 342 can be the same, or different materials can be combined. By setting the staggered mesh structure of the first reinforcing ribs 341 and second reinforcing ribs 342, the radial pressure of the tube body 10 is effectively dispersed, effectively preventing deformation of the tube body 10, improving its overall structural strength, and extending the service life of the tube body 10.

[0035] Furthermore, a corrosion-resistant layer 35 is provided between the inner layer 31 and the reinforcing structure 34. The corrosion-resistant layer 35 is made of epoxy resin or polyethylene material. By providing the corrosion-resistant layer 35 made of epoxy resin or polyethylene material, the pipe body 10 has better corrosion resistance, which improves the corrosion resistance of the pipe body 10 and extends the service life of the pipe body 10.

[0036] Furthermore, a heat-resistant layer 36 is provided between the reinforcing layer 33 and the outer layer 32. The heat-resistant layer 36 is made of glass wool or rock wool. By providing the heat-resistant layer 36, the heat resistance of the tube body 10 is greatly improved, and it can be used in high-temperature environments, thus expanding the application range of the tube body 10.

[0037] Furthermore, a flexible layer 37 is provided between the heat-resistant layer 36 and the outer layer 32. The flexible layer 37 is made of an elastic material, such as silicone or rubber. A metal mesh layer 38 is provided on the outer surface of the flexible layer 37 near the outer layer 32. By providing the elastic flexible layer 37, it can buffer external pressure, making the pipe less prone to deformation under pressure, thereby improving the overall strength and toughness of the pipe and preventing the pipe from breaking under large external forces. At the same time, by providing the metal mesh layer 38, it can further improve the deformation resistance of the pipe body 10. The elastic flexible layer 37 and the metal mesh layer 38 form a double protection, further improving the service life of the pipe body 10.

[0038] Furthermore, the outer layer 32 has a wear-resistant coating 39 on its surface, which is made of epoxy resin, polyethylene, or polyurethane. By providing the wear-resistant coating 39, the tube body 10 can be protected from scratches during dragging and transportation, and the tube body 10 can be prevented from failing prematurely due to stress concentration caused by surface damage, thereby improving the service life of the tube body 10.

[0039] Preferably, the fixing buckle 20 includes two sets of first fixing rings 21 and second fixing rings 22 symmetrically distributed vertically. A fixing plate 23 for fixing is provided between the first fixing rings 21 and second fixing rings 22 on the same side, and the first fixing rings 21 and second fixing rings 22 are rotatably connected to the fixing plate 23. A first connecting platform 24 is provided on the other side of each of the first fixing rings 21 and second fixing rings 22. A fixing rod 25 is provided between the two sets of first connecting platforms 24. One end of the fixing rod 25 is rotatably connected to one set of first connecting platforms 24, and the other end is provided with a threaded locking nut 26. When the first fixing rings 21 and second fixing rings 22 fix two adjacent sets of connecting parts 11, the locking nut 26 abuts against the outer surface of the other set of first connecting platforms 24. When the connecting part 11 of two adjacent sets of pipe bodies 10 is fixed, the first fixing ring 21 and the second fixing ring 22 are fastened to the outside of the connecting part 11. Then, the fixing rod 25 is rotated into the two sets of first connecting platforms 24, and the locking nut 26 is tightened so that the locking nut 26 abuts against the outer side of the first connecting platform 24 on the first fixing ring 21, thereby realizing the quick fixation between the two adjacent sets of pipe bodies 10. Conversely, the quick disassembly between the two adjacent sets of pipe bodies 10 is realized, which simplifies the assembly and replacement steps between the two sets of pipe bodies 10. In particular, when replacing a damaged pipe body 10, there is no need to cut the pipe body 10, thereby shortening the assembly and replacement time.

[0040] Furthermore, one side of the connecting part 11 is provided with an inclined first slope, forming a conical structure between adjacent sets of connecting parts 11. Both the first fixing ring 21 and the second fixing ring 22 are provided with fixing grooves 27 corresponding to the conical structure, and the two inner sides of the fixing grooves 27 are provided with second slopes that abut against the first slope. By providing the first slope, the first slope can guide the installation of the fixing grooves 27, making the installation of the fixing buckle 20 more stable and smooth. The design of the first and second slopes increases the contact area between the fixing buckle 20 and the connecting part 11, resulting in a more uniform distribution of connection strength and preventing cracking caused by localized stress concentration.

[0041] Preferably, one end of the snap-fit ​​portion 17 is provided with a threaded portion, which is threadedly connected to the pipe body 10. The other end of the snap-fit ​​portion 17 is provided with an outwardly protruding rubber ring 14, and the top of the rubber ring 14 has an arcuate portion 141. A locking ring 15 for fixing the position of the rubber ring 14 is provided between the snap-fit ​​portion 17 and the rubber ring 14, and the locking ring 15 is threadedly connected to the snap-fit ​​portion 17. A groove 16 corresponding to the arcuate portion 141 is provided between the rubber ring 14 and the snap-fit ​​groove 18. By setting the arcuate portion 141 and the groove 16 of the rubber ring 14, when the snap-fit ​​portion 17 and the snap-fit ​​groove 18 are connected, the two can be initially fixed, so as to facilitate the rapid installation of the subsequent fixing buckle 20 and improve the installation efficiency of the pipe body 10.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
