A replaceable metal hose

Abstract

The invention discloses a replaceable metal hose. The replaceable metal hose comprises a metal pipe body, a connecting pipe (3) and a flange (4), wherein the metal pipe body is connected with one end of the connecting pipe (3), and the other end of the connecting pipe (3) is connected with the flange (4); the metal pipe body comprises an inner hose (2) and an outer pipe (1), and the inner hose (2) is sleeved with the outer pipe (1); the outer pipe (1) is composed of a plurality of sectional pipe bodies, and the junction of every two adjacent pipe bodies is provided with a seal washer; a cavity is formed between the inner hose and each pipe body of the outer pipe (1), and the inner surface of each cavity is fixedly provided with a spring (6); the bottom of each spring (6) is connected to an elastic layer (7). According to the replaceable metal hose, by means of the cooperation of the springs and the elastic layers, the protective effect is improved, and a split structure is easy to replace and disassemble when the outer pipe fails, so that the service life is prolonged.

Description

technical field [0001] The invention relates to a replaceable metal hose, which belongs to the technical field of metal hoses. Background technique [0002] Metal hose is an important component in the connection pipeline of modern industrial equipment. Metal hoses are used as wire and cable protection tubes for wires, cables, automated instrument signals, and civil shower hoses, with specifications ranging from 3mm to 150mm. Small-diameter metal hoses (inner diameter 3mm-25mm) are mainly used for the protection of sensing lines of precision optical rulers and industrial sensor lines. [0003] Since the metal hose can be bent at will and the internal stress generated by bending under the rated bending radius is extremely small, it can bring great convenience to the installation work and also guarantee the safe operation of the pipeline system. effect. This is the main reason why some piping systems must use metal hoses. [0004] The good comprehensive performance of the m...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a replaceable metal hose, which solves the problem that the pipe body of the existing metal hose is generally an integral structure, and when there is a crack in one place of the pipe body, it will cause Leakage of the entire pipe body makes it impossible to continue to use, the wear resistance of the entire pipe body structure is poor, and it is easy to bend and cause leakage problems
