Description

Technical Field

[0001] The utility model belongs to the technical field of hoses, and particularly relates to a high-temperature and high-pressure braided hose. Background Art

[0002] Hoses are important components in modern industry. Hoses are mainly used as wire and cable protection tubes for wires, cables, and automated instrument signals, as well as civil shower hoses, with specifications ranging from 3 mm to 150 mm. Small-diameter hoses (inner diameter 3 mm - 25 mm) are mainly used for protecting the sensing circuits of precision optical scales and industrial sensor circuits.

[0003] Existing hoses are generally metal bellows. However, the internal corrugated structure of the bellows results in a relatively low internal smoothness, which easily affects the fluidity of the fluid. Especially in some applications with high requirements for fluidity, it is rather inconvenient. Therefore, we have specifically designed a high-temperature and high-pressure braided hose. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a high-temperature and high-pressure braided hose for the above-mentioned existing technical problems, achieving the effect of improving fluidity.

[0005] In view of this, the utility model provides a high-temperature and high-pressure braided hose, including:

[0006] A hose, with a braided layer arranged on the outer side of the hose;

[0007] A connection component, arranged at both ends of the hose;

[0008] Among them, the braided layer is made of a metal material.

[0009] In the above technical solution, further, the connection component includes:

[0010] A connection seat, connected to the hose, and a limit protrusion is arranged at the front end of the connection seat;

[0011] A connection sleeve, arranged at the front end of the connection seat and in limit cooperation with the limit protrusion;

[0012] A connection head, in threaded cooperation with the connection sleeve, and a first sealing ring is arranged between the connection head and the connection sleeve.

[0013] In the above technical solution, further, it further includes:

[0014] A ferrule, arranged on the outer side of the mating end of the connection seat and the hose, and is press-fitted on the hose, with an inner core arranged inside the ferrule. A threaded sink is arranged at the outer port of the inner core and is in cooperation with the connection seat.

[0015] In the above technical solution, further, the inner core includes:

[0016] The first limiting end, which is arranged at the front end of the inner core;

[0017] The second limiting end, which is arranged at the rear end of the inner core;

[0018] Wherein, after stamping, the ferrule is recessed to form a clamping platform, and the clamping platform is clamped between the first limiting end and the second limiting end.

[0019] In the above technical solution, further, it further includes:

[0020] The boss, which is arranged at the front end of the limiting protrusion. A convex edge is arranged at the port of the boss, and the first sealing ring is connected to the boss and clamped inside the convex edge.

[0021] In the above technical solution, further, it further includes:

[0022] The second sealing ring, which is arranged on the mating surface between the inner core and the threaded counterbore.

[0023] In the above technical solution, further, after stamping, the ferrule forms a hexahedron.

[0024] The beneficial effects of the present utility model are as follows: By arranging the braided layer, the structural strength of the hose can be effectively improved, which is helpful for use in high-temperature and high-pressure environments. At the same time, the connection components at both ends are convenient for assembly during use, and the inner wall surface of the hose is smooth, which is helpful for fluid flow.
