Embodiment 1

[0015] figure 1 Shown is a schematic diagram of the structure of the wear-resistant metal composite hose equipped with flanges in the present invention. The structure of this embodiment is suitable for supporting large-diameter pipelines. It includes flanges 1, connecting pipes 2, inner rings 3, outer rings 4, network pipes 5, Bellows 6, rubber lining 7 and spring 8. The connecting pipe 2 is located at both ends of the corrugated pipe 6, and the outer wall of the connecting pipe 2 and the corrugated pipe 6 are respectively fitted with the inner ring 3 and the outer ring 4, and a rubber lining 7 is inserted in the outer crest of the corrugated pipe 6 and the whole section is covered with the network pipe 5. Then the inner ring 3, the outer ring 4, the corrugated pipe 6, and the network pipe 5 are fixedly connected with the connecting pipe 2. The outer port of the connecting pipe 2 is fixedly connected with the flange 1 . A spring 8 is plugged in the inner hole of the connecti...

Embodiment 2

[0017] figure 2 It is a schematic structural diagram of replacing the flange 1 of the external connector in the present invention with a quick joint 1, and the rest of the pipe body is completely the same as that of embodiment 1, and the technical effect after implementation is similar to that of embodiment 1. This embodiment is mainly matched with small diameter pipelines.

Abstract

The invention discloses a wear-resisting metal composite hose comprising a flange, an adapter, an inner ring, an outer ring, a net pipe, a corrugated pipe, a rubber lining and springs, wherein the two ends of the adapter are respectively and fixedly connected with the flange, the inner ring, the outer ring, the net pipe and the corrugated pipe which are mutually sheathed to form a common joint. The wear-resisting metal composite hose fills the rubber lining between the external wave crests of the corrugated pipe, and fills the springs in the whole section in the inner hole of the adapter and the corrugated pipe; the two ends of the spring are fixedly connected with the adapter port; the diameter of alloy steel wire for rolling the spring is much bigger than the thickness of the thin wall of the corrugated pipe, and the lining of the spring forms a flexible protection and guidance structure in the corrugated pipe. The wear-resisting metal composite hose is provided with double wear-resisting layers, and the spring in the corrugated pipe has strong wear-resisting property, thus greatly improving service life, reducing times for replacing metal corrugated pipes, saving production cost and improving production efficiency.

Description

technical field [0001] The invention relates to a metal hose, in particular to a metal composite hose provided with a wear-resistant structure. Background technique [0002] Furnace auxiliary materials used in modern large-scale iron and steel industry are usually transported by pipelines with high-efficiency logistics characteristics and environmental friendliness. In order to facilitate the flexible alignment output of the pipeline terminal, a hose is arranged at the pipeline terminal to make full use of the flexible and flexible positioning operation of the hose. At present, the hoses used mainly include rubber hoses and metal hoses. Due to the poor wear resistance of rubber hoses, the supporting quantity is limited, and a large number of metal bellows with slightly better wear resistance are used in the project. Although the metal bellows is made of metal, there is a large gap between the wall thickness of the metal bellows and the conventional metal pipe. The thin-wal...
