Abstract
Description
Technical Field
[0001] This utility model relates to the field of water hose technology, specifically a high-strength water hose with a double-layer woven structure. Background Technology
[0002] Water hoses, as flexible conduits for liquid transportation, are widely used in fire rescue, agricultural irrigation, industrial water supply, and municipal engineering. Their core function is to achieve efficient liquid transmission under certain pressure, thus requiring strict standards for structural strength, pressure resistance, and durability. In existing technologies, the main structure of water hoses typically includes an inner lining layer and a braided reinforcement layer, with the braided reinforcement layer being the key structure determining the mechanical properties of the hose. Currently, most mainstream water hoses employ a composite structure of a single-layer braided reinforcement layer and a single-layer inner lining layer, using the interlacing warp and weft structure of the braided layer to improve tensile strength.
[0003] Although existing braided hoses have achieved basic strength improvements, the warp and weft density and structural stability of single-layer braided hoses are limited. Under the impact of high-pressure liquid, local warp and weft slippage is likely to occur, leading to excessive expansion of the hose diameter. In extreme cases, this can cause the braided layer to tear or the inner lining to rupture, resulting in liquid leakage or even explosion accidents. The exposed fibers on the surface of the single-layer braided hose are prone to single-filament breakage or local wear when dragged on rough ground or scratched by sharp objects, which in turn leads to the inner lining losing its protection and becoming damaged.
[0004] Therefore, a high-strength water hose with a double-layer woven structure is needed to improve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a high-strength water hose with a double-layer woven structure to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A high-strength water hose with a double-layer woven structure includes:
[0008] The main structure has a double-layer woven structure;
[0009] The wear-resistant structure is evenly spaced on the outside of the main structure, and the wear-resistant structure protrudes from the outer side of the main structure.
[0010] The groove structure is evenly spaced on the outside of the main structure, allowing for convenient curling of the main structure.
[0011] As a preferred embodiment of this utility model, the main structure includes an inner braided layer and an outer braided layer.
[0012] As a preferred embodiment of this utility model, the inner braided layer includes an inner braided layer, and a rubber liner is provided on the inner side of the inner braided layer; the outer braided layer includes an outer braided layer; and a middle layer of rubber is provided between the inner braided layer and the outer braided layer.
[0013] As a preferred embodiment of this utility model, the outer braided layer is provided with reinforcing ribs at equal intervals inside.
[0014] As a preferred embodiment of this utility model, an outer rubber layer is provided on the outer side of the outer braided layer, and the wear-resistant structure and the groove structure are both provided on the outer side of the outer rubber layer.
[0015] As a preferred embodiment of this utility model, the wear-resistant structure includes a convex ring disposed on the outer rubber layer, and the convex ring is provided with a set of slots.
[0016] As a preferred embodiment of this utility model, the groove structure includes several annular grooves.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] This utility model adopts a double-layer braided structure as the main reinforcing layer of the water hose, which effectively solves the problem that the existing single-layer braided layer is prone to warp and weft slippage and excessive diameter expansion under high pressure. The inner and outer braided layers are combined with the middle rubber layer to form a composite system that synergistically bears pressure. This system can significantly disperse and absorb internal liquid pressure, suppress the displacement and deformation of the braided lines, thereby greatly improving the overall structural stability and burst resistance of the water hose and preventing the risk of tearing or rupture under high pressure.
[0019] This invention features a prominent wear-resistant structure and a protective rubber layer on the outer layer, effectively overcoming the defects of easy wear and fiber exposure on the surface of existing water hose braided layers. The wear-resistant structure, as the primary contact point, bears external friction and scratches, protecting the lower braided layer and inner lining from damage. At the same time, the outer rubber layer isolates environmental erosion, together significantly enhancing the surface durability and wear resistance of the water hose and extending its service life under harsh working conditions.

[0029] Please see Figure 1-4 This utility model provides a technical solution:
[0030] Example 1, please refer to Figure 1 , 2 3 and 4, a high-strength water hose with a double-layer woven structure, including a main structure, a wear-resistant structure and a groove structure.
[0031] The main structure forms the base tube of the water hose. It adopts a double-layer braided design, which allows each braided layer to support and restrain each other when the water hose is subjected to internal water pressure, effectively dispersing stress, significantly improving the burst strength and pressure resistance of the water hose, and preventing rupture under high pressure.
[0032] On the outer side of the main structure, wear-resistant structures are installed at equal intervals. These wear-resistant structures protrude outward from the outer surface of the hose, so that when the hose is dragged, moved, or rubbed against the ground or other objects, the protruding wear-resistant structures bear the wear first, thereby effectively protecting the outer surface of the main structure and extending the service life of the hose.
[0033] The grooves are also evenly spaced on the outside of the main structure. The presence of these grooves gives the hose wall greater flexibility in the corresponding positions. When coiling and storing, the hose can bend more easily along these pre-set grooves, making the coiling process more labor-saving and smoother. The coiled shape is also more regular, making it easier to transport and store.
[0034] Example 2: The main structure specifically includes an inner braided layer and an outer braided layer. The inner braided layer directly contacts the internal fluid, providing a basic pressure-bearing skeleton; the outer braided layer further strengthens the overall structure. This double-layered braiding design forms a composite reinforced structure, and the synergistic effect allows the hose to possess both flexibility and high strength.
[0035] Preferably, the inner braided layer is specifically an inner braided layer 6, the inner surface of which is laminated with a rubber liner 5. The rubber liner 5 can effectively seal and prevent fluid from penetrating through the braided layer. At the same time, its smooth surface can reduce fluid transport resistance. Between the inner braided layer 6 and the outer braided layer 8, a middle layer rubber 7 is also provided. The middle layer rubber 7 can not only firmly bond the inner and outer braided layers into a whole and improve the interlayer bonding performance, but also play an additional sealing and buffering role, further improving the pressure bearing capacity and durability of the water hose.
[0036] Example 3, based on Example 2, further optimizes the main structure.
[0037] Inside the outer braided layer 8, several reinforcing ribs 9 are woven or embedded at equal intervals. These reinforcing ribs 9 can be made of high-strength synthetic fibers or metal materials. As the main load-bearing elements, they can significantly enhance the circumferential strength and axial tensile strength of the outer braided layer 8 and even the entire water hose wall, enabling it to adapt to higher working pressures.
[0038] The outer braided layer 8 is also covered with an outer rubber layer 10. The outer rubber layer 10 mainly serves a protective function, preventing the outer braided layer 8 from being eroded by the external environment, such as sun exposure, rain, and chemical corrosion. The aforementioned wear-resistant structure and groove structure are integrally formed on the outer surface of the outer rubber layer 10 through processes such as molding and vulcanization, making these functional structures more firmly bonded to the water hose body. Example
[0039] Based on Example 3, this example specifically describes one implementation of the wear-resistant structure and the groove structure.
[0040] The wear-resistant structure is specifically a ring-shaped protrusion 3 on the surface of the outer rubber layer 10. These protrusions 3 are evenly distributed to form a series of protective bands. In order to ensure wear resistance without excessively increasing the rigidity and weight of the hose, a set of through slots 4 can be opened on the protrusions 3 in the circumferential direction. These slots 4 increase the elasticity of the protrusions 3, so that the protrusions 3 can better adapt to deformation when the hose is bent.
[0041] The groove structure specifically consists of several annular grooves 2 surrounding the outer wall of the hose. These annular grooves 2 can be set between adjacent convex rings 3, or can be set independently according to flexibility requirements. The annular grooves 2 locally reduce the thickness of the pipe wall, creating natural bending hinge points, so that the hose can bend preferentially at these annular grooves 2 when it is rolled up, thereby achieving easy and regular winding. The alternating arrangement of convex rings 3 and annular grooves 2 together constitutes the functional texture of the outer surface of the hose.
[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
