Problems solved by technology

[0005] In the prior art, in order to achieve a more ideal shock absorption effect for metal hoses, two corrugated pipes nested in each other are generally used, and shock-absorbing materials are arranged in the two corrugated pipes, or multiple wires are installed in the net sleeve. The small bellows are arranged side by side to achieve further shock absorption effect. The two bellows in the first scheme will cause incongruity during the bending process, and will also have a certain impact on the bending angle range. The second scheme not only It only has a large impact on the bending angle range, and at the same time, because the inner diameter of the bellows becomes smaller and the number of bellows increases, it brings inconvenience to subsequent installation and use

Embodiment 1

[0023] like figure 1 and figure 2 As shown, a corrugated metal hose with a shock absorbing function is shown, which includes an annular metal bellows 1 and joints 2 welded at both ends thereof. Metal jacket 3, said metal jacket 3 is welded by two semicircular snap rings 10, the two ends of the snap rings shown are respectively provided with a flat lug plate 11, said metal jacket 3 and annular metal bellows 1 A glass fiber cloth layer 4 is filled in between, and a metal mesh sleeve 8 is arranged outside the annular metal bellows 1, and the metal mesh sleeve 8 is welded and fixed to the joints 2 at both ends.

Embodiment 2

[0025] like image 3 and Figure 4 As shown, there is a rubber layer 5 on the outside of the peak position of the annular metal bellows 1, and the glass fiber cloth layer 4 is bonded to the outside of the rubber layer 5 by resin. The annular metal bellows 1 and the metal jacket 3 The gaps in between are filled by the rubber layer 5 . The crest of the annular metal bellows 1 is provided with a plurality of notches 6, the inner side of the rubber layer 5 is provided with a groove 9 wrapping the crest, and the groove 9 is provided with a plurality of notches to cooperate with the notches. The raised 7.

[0026] A method for producing a corrugated metal hose with a shock-absorbing function, the specific steps are as follows:

[0027] 1) Multiple crests of the annular metal bellows 1 are pressed with multiple notches along a straight line, so that the notches 6 between each row of crests are aligned in a straight line, and the number of notches is not less than four, and four i...

Abstract

The invention provides a corrugated metal hose with a damping function. The corrugated metal hose comprises an annular metal corrugated pipe and connectors welded to the two ends of the metal corrugated pipe. The parts, located at all wave crests, of the annular metal corrugated pipe are each sleeved with an annular metal jacket. The space between the metal jackets and the annular metal corrugatedpipe is filled with a glass fiber cloth layer. A metal casing is arranged outside the annular metal corrugated pipe. The annular metal corrugated pipe are welded and fixed with the connectors at thetwo ends. By sleeving the wave crests of the annular metal corrugated pipe with the annular metal jackets, the better damping effect is achieved, and meanwhile, bending of the corrugated hose is not hampered.

Description

technical field [0001] The invention relates to a corrugated metal hose with shock-absorbing function, which belongs to the field of metal hoses. Background technique [0002] Metal hose is an important connecting component in engineering technology, which is composed of corrugated flexible pipe, net sleeve and joint. Used as compensating elements, sealing elements, connecting elements and shock absorbing elements in various gas transmission, infusion pipeline systems and length, temperature, position and angle compensation systems, used in aerospace, petrochemical, mining electronics, machinery shipbuilding, medical treatment Health, textile electronics, energy construction and other fields. The latest national specification for metal hoses is "General Technical Conditions for Corrugated Metal Hose" (GB / T14525-2010), which came into effect on October 1, 2011. [0003] Corrugated metal hose (referred to as bellows) is a high-quality flexible pipe in modern industrial pipel...
