Description

Technical Field

[0001] The utility model belongs to the technical field of rubber hoses, and in particular relates to a steel wire braided high-pressure rubber hose capable of preventing negative pressure deformation. Background Art

[0002] High-pressure hose refers to the pipeline used for conveying liquid transmission such as petroleum-based and water-based liquids with a certain pressure and temperature in the mechanized and automated hydraulic systems of oil field development, engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and various industrial sectors.

[0003] Nowadays, when most high-pressure hoses are transporting liquid, when the liquid transportation stops suddenly, negative pressure will be generated in the tube, and the suction caused by the negative pressure will easily cause the hose to deform. Therefore, we propose a steel wire braided high-pressure hose that can prevent negative pressure deformation. Utility Model Content

[0004] The utility model aims to provide a steel wire braided high-pressure rubber hose which is resistant to negative pressure deformation, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a steel wire braided high-pressure hose that prevents negative pressure deformation, comprising a high-pressure hose body, the high-pressure hose body comprising a hose, a reinforcement layer is arranged on the outside of the hose, and a steel wire braided layer is arranged on the outside of the reinforcement layer;

[0006] A No. 1 connector and a No. 2 connector are respectively provided at both ends of the high-pressure hose body, and sealing rings are fixedly sleeved inside the No. 1 connector and the No. 2 connector, and fixing components are provided inside the No. 1 connector and the No. 2 connector, and sealing plugs are provided at the ends of the No. 1 connector and the No. 2 connector.

[0007] As a preferred implementation, the reinforcement layer is made of steel strip, and the reinforcement layer is spirally wound around the outside of the hose.

[0008] As a preferred embodiment, the interior of the No. 1 connector is provided with an internal thread, the exterior of the No. 2 connector is provided with an external thread, and the No. 1 connector and the No. 2 connector are adapted to each other.

[0009] As a preferred implementation, the sealing ring is made of rubber material, and the sealing ring is movably sleeved with the end of the high-pressure hose body.

[0010] As a preferred embodiment, the fixing assembly includes a support pad, a fixing bolt and a fixing block. The support pad is made of rubber material, and the top of the support pad is arc-shaped. The fixing block is movably sleeved on the outside of the bottom end of the fixing bolt, and the shape of the fixing block is arc-shaped.

[0011] As a preferred implementation, the sealing plug is made of rubber material and has a semicircular ring shape.

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

[0013] The steel wire braided high-pressure hose that prevents negative pressure deformation can effectively enhance the hardness of the high-pressure hose itself by spirally winding a layer of steel belt on the outside of the hose and combining it with the outermost steel wire braided layer. In this way, when the liquid is suddenly stopped from being transported, the high-pressure hose will not be deformed due to negative pressure suction, thereby bringing convenience to the use of the high-pressure hose.

[0014] The steel wire braided high-pressure hose that prevents negative pressure deformation can facilitate the connection between two high-pressure hoses during use by providing a No. 1 connector and a No. 2 connector, and can facilitate quick disassembly and assembly of the No. 1 connector and the No. 2 connector by using a fixing component, while the sealing ring and the sealing plug can enhance the sealing between the high-pressure hose body and the No. 1 connector and the No. 2 connector, thereby effectively preventing leakage of liquid transported inside the high-pressure hose.

[0022] In this embodiment, when a reinforcing layer 12 is provided between the hose 11 and the steel wire braided layer 13, that is, a steel belt is spirally wrapped around the outside of the hose 11, the hardness of the high-pressure hose body 1 can be enhanced. When the high-pressure hose suddenly stops transporting liquid, negative pressure will be instantly generated inside the high-pressure hose. At this time, the high-pressure hose will not be deformed due to the negative pressure suction.

[0024] In this embodiment, two adjacent high-pressure hose bodies 1 can be spliced ​​using connector No. 1 2 and connector No. 2 3, and the sealing ring 4 made of rubber material can utilize its own elastic properties to make the sealing ring 4 and the end of the high-pressure hose body 1 fit tightly, so that when the high-pressure hose transports liquid, it can effectively prevent the liquid from leaking. At the same time, two semicircular sealing plugs 6 can be used to seal the end of connector No. 1 2 or connector No. 2 3, which can further prevent the liquid transported inside the high-pressure hose from leaking.
