Description

Technical Field

[0001] This utility model relates to the field of metal hose technology, specifically a corrosion-resistant metal hose. Background Technology

[0002] Metal hoses play an important role in the industrial field. They can be used as pipelines to transport liquids or gases and are suitable for transporting high-temperature, high-pressure, and corrosive media. For example, in industries such as petroleum, chemical, and metallurgy, metal hoses are widely used to transport media such as oil, natural gas, and corrosive solutions, playing a crucial role. In addition, metal hoses can also be used for connecting industrial equipment, such as pumps, pressure vessels, and valves.

[0003] Existing metal hoses are mostly coated with corrosion-resistant paint inside to increase their corrosion resistance. However, after long-term use, the corrosion-resistant coating is prone to peeling off, resulting in a decrease in corrosion resistance. Furthermore, metal hoses are prone to cracking when bent excessively, leading to damage. Therefore, we propose a corrosion-resistant metal hose. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a corrosion-resistant metal hose. It enhances the corrosion resistance of the hose's inner wall, making the hose more durable. Furthermore, the protective spring effectively protects the surface of the hose, limiting the bending angle during bending and preventing damage. The protective layer also separates the protective spring from the metal outer sheath, preventing mutual wear. This invention solves the problems of existing metal hoses, which often rely on internal corrosion-resistant coatings for increased resistance, but these coatings tend to peel off over time, reducing corrosion resistance. Additionally, excessive bending can easily cause cracks and damage to the metal hose.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned effect of increasing the corrosion resistance of the inner wall of the hose body, making the hose body more durable, and to facilitate the protection of the hose body surface under the action of the protective spring, thus limiting the bending angle of the hose body during bending and preventing damage to the hose body, the protective layer separates the protective spring from the metal jacket, preventing mutual wear between the protective spring and the metal jacket. This utility model provides the following technical solution: a corrosion-resistant metal hose, including a hose body, the inner wall of which is fixedly connected with a corrosion-resistant layer, and multiple protective springs disposed on the surface of the hose body. A protective layer is fitted onto the surface of the protective spring, and a metal jacket is fitted onto the surface of the protective layer. A first connector is fixedly connected to the left end of the hose body, and a second connector is fixedly connected to the right end of the hose body. By setting a corrosion-resistant layer, the corrosion resistance of the inner wall of the hose body can be increased, making the hose body more durable. Under the action of the protective spring, the surface of the hose body is easily protected. When the hose body is bent, the protective spring restricts the bending angle of the hose body, thereby preventing damage to the hose body. Under the action of the protective layer, the protective spring and the metal jacket are separated, preventing mutual wear between the protective spring and the metal jacket.

[0008] As a preferred technical solution of this utility model, the material of the hose body is polyurethane, and the material of the corrosion-resistant layer is fiberglass. Polyurethane has good wear resistance and mechanical properties, and fiberglass hoses are usually made of glass fiber reinforced plastic, which has the characteristics of being lightweight, high-strength, and corrosion-resistant.

[0009] As a preferred technical solution of this utility model, the material of the protective layer is rubber. The advantages of rubber mainly include high elasticity, strong adaptability, shock absorption, vibration absorption, easy repair, and flexible lining methods.

[0010] As a preferred embodiment of this utility model, the left and right ends of the plurality of protective springs are respectively fixedly connected to the right end of the first connector and the left end of the second connector, the left and right ends of the protective layer are respectively fixedly connected to the right end of the first connector and the left end of the second connector, and the left and right ends of the metal jacket are respectively fixedly connected to the right end of the first connector and the left end of the second connector. By setting the first connector and the second connector, it is convenient to connect the metal hoses, so that the first connector can be inserted into the second connector, thereby increasing the tightness of the connection between the first connector and the second connector.

[0011] As a preferred embodiment of this utility model, a sealing ring is fixedly connected to the right side of the inner wall of the second connector. By setting the sealing ring, the connection between the first connector and the second connector is made more airtight.

[0012] As a preferred technical solution of this utility model, a connecting flange is fixedly connected to the surface of the first connecting member and the surface of the second connecting member. A plurality of fastening bolts are provided on the inner wall of the connecting flange on the right side. By providing the connecting flange and fastening bolts, it is easy to tightly connect the first connecting member and the second connecting member.

[0015] Beneficial effects:

[0016] 1. This metal hose, by setting a corrosion-resistant layer, can increase the corrosion resistance of the inner wall of the hose body, making the hose body more durable. Under the action of the protective spring, it is easy to protect the surface of the hose body. When the hose body is bent, the protective spring restricts the bending degree of the hose body, thereby avoiding damage to the hose body. Under the action of the protective layer, the protective spring is separated from the metal jacket, preventing mutual wear between the protective spring and the metal jacket.

[0017] 2. The metal flexible hose, by providing a first connector and a second connector, facilitates the connection between metal flexible hoses, allowing the first connector to be inserted into the second connector, thereby increasing the tightness of the connection between the first connector and the second connector.
