A high-temperature and high-pressure resistant metal hose

Abstract

This utility model discloses a high-temperature and high-pressure resistant metal hose, comprising a metal outer tube, an inner metal tube sleeved inside the outer metal tube, a multi-layer metal mesh sleeve surrounding the outer metal tube, and multiple layers of asbestos cloth wrapped around the outside of the metal mesh sleeve. The outer metal tube protects the inner metal tube and enhances the overall strength and pressure resistance. The multi-layer metal mesh sleeve tightly wrapped around the outer metal tube protects the outer metal tube and allows it to withstand greater pressure. The multiple layers of asbestos cloth tightly wrapped around the outside of the metal mesh sleeve insulate against high temperatures, enabling the metal hose to be used for extended periods in high-temperature and high-pressure environments, reducing replacement frequency and costs.

Description

Technical Field

[0001] This utility model belongs to the field of metal pipe technology, and in particular relates to a high-temperature and high-pressure resistant metal flexible hose. Background Technology

[0002] Metal hoses are flexible pipes made of metal, possessing flexibility, pressure resistance, and sealing properties. They are widely used in industries such as industrial, energy, chemical, and aerospace. Their main functions include compensating for displacement, absorbing vibration, sealing connections, and adapting to complex pipeline layouts.

[0003] Because metal hoses are used in a variety of complex environments, especially in high-temperature and high-pressure environments, ordinary metal hoses cannot meet the requirements, resulting in a short service life and frequent replacement, which is both cumbersome and increases costs. Utility Model Content

[0004] To address the above problems, this utility model provides a metal hose resistant to high temperature and high pressure.

[0005] This utility model is implemented as follows: A high-temperature and high-pressure resistant metal hose includes a metal outer tube, inside which a metal inner tube is tightly fitted. The metal outer tube protects the metal inner tube and enhances the overall strength and pressure resistance. The two ends of the metal inner tube are welded to the two ends of the metal outer tube, making the metal outer tube and metal inner tube a single unit with a reliable connection. The outer metal tube is tightly fitted with multiple layers of metal mesh made of woven metal wire, which protects the metal outer tube and enables it to withstand greater pressure. The ends of the metal mesh are connected to the metal outer tube. The two ends are welded together, making the metal mesh sleeve and the metal outer tube a whole, ensuring the stability of the position of the metal mesh sleeve, and thus ensuring that the metal wires will not come loose. The connection between the end of the metal mesh sleeve and the metal outer tube is tightly fitted and welded with a joint, which not only ensures the reliable connection between the end of the metal mesh sleeve, the end of the metal outer tube, the end of the metal inner tube and the joint, but also improves the stability and reliability of the position of the end of the metal mesh sleeve, and facilitates connection with external equipment. The outside of the metal mesh sleeve is tightly wrapped with multiple layers of asbestos cloth to insulate against high temperatures, so that the metal hose composed of the metal mesh sleeve, the metal outer tube and the metal inner tube can withstand higher temperatures.

[0006] Preferably, rubber sleeves are tightly fitted at the connection points between the two ends of the asbestos cloth and the joint, thereby limiting the position of the two ends of the asbestos cloth and ensuring that the ends of the asbestos cloth are tightly attached to the metal mesh sleeve.

[0007] Preferably, the inner diameter of the inner metal tube is 14-18 mm, and the diameter of the outer metal tube is 23-27 mm.

[0008] Preferably, the metal mesh sleeve has 4 to 6 layers, providing good protection.

[0009] Preferably, the asbestos cloth has 3 to 5 layers, which provides good high-temperature resistance.

[0010] Preferably, the outer metal tube, the inner metal tube, and the metal mesh sleeve are made of stainless steel, which has high strength, is not easy to rust, and has a long service life.

[0011] The beneficial effects of this utility model are: the outer metal tube protects the inner metal tube and enhances the overall strength and pressure resistance. The outer metal tube is tightly fitted with multiple layers of metal mesh woven from metal wire, which protects the outer metal tube and enables it to withstand greater pressure. The outer metal mesh is tightly wrapped with multiple layers of asbestos cloth to insulate against high temperatures, allowing the metal hose to be used for a long time in high temperature and high pressure environments, reducing the frequency of replacement and costs.

[0014] To better understand the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, further illustrates this utility model.

[0015] like Figure 1The illustrated high-temperature and high-pressure resistant metal hose includes a metal outer tube 1, inside which a metal inner tube 2 is tightly fitted. The inner diameter of the metal inner tube 2 is 16 mm, and the diameter of the metal outer tube 1 is 25 mm. The metal outer tube 1 protects the metal inner tube 2 and enhances the overall strength and pressure resistance. The two ends of the metal inner tube 2 are welded to the two ends of the metal outer tube 1, making the metal outer tube 1 and metal inner tube 2 a single unit with reliable connection. The outer metal tube 1 is tightly fitted with multiple layers of metal mesh sleeve 3 made of woven metal wire, which protects the metal outer tube 1 and enables it to withstand greater pressure. The metal mesh sleeve 3 has 5 layers, providing good protection. The ends of the metal mesh sleeve 3 are welded to both ends of the outer metal tube 1, making the metal mesh sleeve 3 and the outer metal tube 1 a single unit. This ensures the stability of the position of the metal mesh sleeve 3 and prevents the metal wires from coming loose. A connector 4 is tightly fitted and welded to the connection between the end of the metal mesh sleeve 3 and the outer metal tube 1, ensuring a reliable connection between the ends of the metal mesh sleeve 3, the outer metal tube 1, the inner metal tube 2, and the connector 4. This further improves the stability and reliability of the end position of the metal mesh sleeve 3 and facilitates connection to external equipment. Multiple layers of asbestos cloth 5 are tightly wrapped around the outside of the metal mesh sleeve 3 to insulate against high temperatures, allowing the flexible metal hose formed by the metal mesh sleeve 3, outer metal tube 1, and inner metal tube 2 to withstand higher temperatures. The asbestos cloth 5 has four layers, providing excellent high-temperature resistance.

[0016] The ends of the asbestos cloth 5 are tightly fitted with rubber sleeves 6 at the connection points with the joints 4. The rubber sleeves 6 are made of high-temperature resistant silicone rubber. The rubber sleeves 6 limit the position of the ends of the asbestos cloth 5, so that the ends of the asbestos cloth 5 are tightly attached to the metal mesh sleeve 3.

[0017] The outer metal tube 1, the inner metal tube 2, and the metal mesh sleeve 3 are made of stainless steel, which has high strength, is not easy to rust, and has a long service life.

[0018] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
