[0019] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.
[0020] Embodiment 1.
[0021] like Figure 1 to Figure 2 As shown, the utility model provides a direct drinking water pipe, which includes a base material layer 1 and a mesh layer 2 and a pipe outer layer 4 which are sequentially sleeved outside the base material layer 1, and a reinforcing rib 3 is arranged between the mesh layer 2 and the pipe outer layer 4; the reinforcing rib 3 surrounds the outside of the mesh layer 2; the cross-section of the reinforcing rib 3 is semicircular, elliptical, square or triangular.
[0022] Specifically, the mesh layer 2 is elastic; the mesh layer 2 includes a plurality of yarns, and the yarns may be yarn latex composite yarns, latex composite yarns, TPR composite yarns, TPE composite yarns, nylon yarns or / and fiber yarns. A plurality of the yarns are woven into a mesh. In actual use, when water flows into the direct drinking water pipe, the mesh layer 2 can slightly expand and contract, has elasticity, and generates lateral tension, which can effectively improve the water pressure resistance and tensile strength of the direct drinking water pipe. At the same time, reinforcing ribs 3 are arranged in the direct drinking water pipe to effectively strengthen the stress resistance of the direct drinking water pipe under mechanical fatigue, and improve the service life and bending resistance of the direct drinking water pipe.
[0023] Furthermore, the substrate layer 1 includes a first inner layer 11 and a second inner layer 12 which are sequentially arranged from the inside to the outside.
[0024] Specifically, the first inner layer 11 can be made of PE, TPU, TPV, TPE, PEX, PP or PU; the second inner layer 12 can be made of PE, TPU, TPV, TPE, PEX, PP or PU. The thickness of the first inner layer 11 is 0.02-1MM, and the thickness of the second inner layer 12 is 0.02-2MM. In actual use, the substrate layer 1 is made of two different soft materials to further improve the bending resistance of the direct drinking water pipe.
[0025] Furthermore, the outer layer 4 of the pipe can be made of materials such as TPE, PU, PE, PEX, PVC, TPV or TPU. The thickness of the outer layer 4 of the pipe is 0.02-5MM, which can further improve the anti-bending ability of the direct drinking water pipe.
[0026] Furthermore, the reinforcing rib 3 can be made of PE or PP material. The diameter of the reinforcing rib 3 is 0.05-5MM.
[0027] An extrusion molding device is used for synchronously extruding a first inner layer 11 and a second inner layer 12, and making the second inner layer 12 wrap around the first inner layer 11.
[0028] The extrusion molding device can realize the co-extrusion of the first inner layer 11 and the second inner layer 12, thereby simplifying the production steps of the direct drinking water pipe.
[0029] All technical features in this embodiment can be freely combined according to actual needs.
[0030] Embodiment 2.
[0031] The difference between this embodiment and the first embodiment is that the plurality of yarns are twisted into a plurality of wires and then arranged transversely outside the base material layer 1 .
[0032] In actual use, a plurality of the yarns are twisted into a plurality of wires, which improves the overall tensile strength of the yarns. The twisted wires are then transversely installed outside the substrate layer 1, which can effectively improve the tensile strength of the direct drinking water pipe.
[0033] The remaining structures of this embodiment are the same as those of the first embodiment. The same structures can adopt the analysis of the first embodiment, which will not be described in detail here.
[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
