Description

Technical Field

[0001] This utility model relates to the field of water pipe technology, specifically to a tensile-resistant rubber knitted water pipe. Background Technology

[0002] In various industrial production and daily life water supply and drainage scenarios, water pipes serve as crucial water conveyance channels, and their performance directly affects the operational stability and service life of the entire system. In industrial fields, such as mining and construction sites, water pipes are frequently subjected to external forces such as dragging, bending, and compression by heavy objects.

[0003] In industrial settings such as mining and construction sites, water pipes are frequently subjected to external forces such as dragging, bending, and compression by heavy objects. Ordinary rubber water pipes, due to their limited tensile strength, are prone to thinning and cracking under these forces, leading to leaks or even pipe failure. This not only disrupts normal production operations but also significantly increases maintenance and time costs due to frequent pipe replacements. Utility Model Content

[0004] The purpose of this invention is to provide a tensile-resistant rubber knitted water pipe that has the advantage of tensile strength and solves the problem of poor tensile strength of current rubber water pipes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tensile-resistant rubber knitted water pipe, comprising a rubber water pipe, wherein a tensile ring is provided on the outer edge of the rubber water pipe, and the rubber water pipe includes a main body layer, wherein a tensile layer is provided on the outer edge of the main body layer, and a reinforcing layer is provided on the inner edge of the main body layer, wherein a protective layer is provided on the outer edge of the tensile layer, and the tensile layer is formed by interlacing several knitted threads.

[0006] Preferably, the main body layer is made of natural rubber and styrene-butadiene rubber.

[0007] Preferably, the tensile layer is arranged in a mesh shape and covers the outer edge of the main body layer. There are four knitting threads, which are spirally wound together and together form a buffer groove.

[0008] Preferably, the tensile layer is made of ultra-high molecular weight polyethylene fiber.

[0009] Preferably, the protective layer is made of polyurethane and covers the outer edge of the tensile layer.

[0010] Preferably, the reinforcing layer is made of nanoscale silicon dioxide.

[0011] Preferably, the tensile ring is spiral-shaped, and the spiral spacing is between 8 and 12 cm.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a main layer, a tensile layer, a protective layer, and a reinforcing layer, features a tensile layer made of ultra-high molecular weight polyethylene fiber. Its tensile strength is several times higher than that of ordinary fibers, effectively improving the tensile performance of the water pipe. Ultra-high molecular weight polyethylene fiber also possesses excellent tensile strength and wear resistance, and has a low density, significantly enhancing the tensile capacity of the water pipe without adding excessive weight. The protective layer effectively resists scratches, abrasions, and punctures from sharp objects, protecting the internal rubber and knitted layers from damage. Nylon material also has high strength and wear resistance, and good chemical stability, enhancing the service life of the water pipe in harsh environments. The reinforcing layer, made of nano-silica, effectively improves the tensile strength, wear resistance, and anti-aging properties of the rubber. When uniformly dispersed in the rubber matrix, it enhances the interaction between rubber molecules, improving overall strength.

[0014] 2. This utility model utilizes a tensile ring positioned on the outer edge of the rubber water pipe. When the water pipe is subjected to tensile force, the spiral-shaped tensile ring can share part of the tensile force, preventing excessive deformation of the water pipe and further improving the overall tensile strength of the water pipe. Simultaneously, the tensile ring also enhances the water pipe's compressive strength, making it less prone to deformation under external pressure. Attached Figure Description

In specific implementation, the tensile layer 12 abandons simple plain knitting and adopts a more complex and stable double-layer or multi-layer knitting structure. For example, a spiral interlacing knitting process is used to make the fibers evenly distributed under stress in all directions, avoiding stress concentration points. Meanwhile, during the weaving process, the spacing and tension of the fibers are reasonably adjusted to ensure that the woven layer is tightly attached to the inner rubber layer, forming a cohesive whole that enhances the structural stability of the water pipe under tension. The inner edge of the main body layer 11 is provided with a reinforcing layer 14, and the outer edge of the tensile layer 12 is provided with a protective layer 13.
