Description
Technical field
The present invention relates to a kind of corrugated flexible metal tubes with shock-absorbing function, belong to metal hose field.
Background technique
Metal hose is connecting elements important in engineering technology, is combined by corrugated flexible hoses, net cover and connector.In
In various gas transmissions, infusion pipeline system and length, temperature, position and angle compensation system as compensating element, sealing element,
Connecting element and damper element are applied to aerospace, petrochemical industry, mine electronics, mechanical shipbuilding, health care, light textile
Each fields such as electronics, energy building.The newest national regulation of metal hose is " corrugated flexible metal tube general technical specifications " (GB/
T14525-2010), implement on October 1st, 2011.
Corrugated flexible metal tube (abbreviation bellows) is a kind of flexible duct of high-quality in modern industry pipeline.It mainly by
Bellows, net cover and connector composition.Its inner tube is the thin-wall stainless steel bellows with spiral shape or annular waveform, bellows
The net cover of outer layer is to be woven by stainless steel wire or steel band by certain parameter.The connector or flange at hose both ends be and visitor
What the connector or flange of family pipeline matched.
Corrugated flexible metal tube is from structure, and the training material of metal bellows has two clock of band and tubing, they are ok
Mold ring bellows and helical fissure pipe.For no other reason than that the molding bellows of band always have certain length soldering or
The hasp and connector of melting welding, these places usually accumulate the residue of working media, and precipitate to have and clean test and working media
In introduction of contaminants inner cavity.Therefore, its is relatively weaker using Reliability.Ring bellows is several torus membranes
The semicircular ring phase cut-grafting centripetal with several concave surfaces of piece outer rim, the special geometric of inner edge and the semicircular ring phase cut-grafting of several concave surface vests
The pipe of shape.For its blank based on tubing, this kind of bellows has the spies such as flexibility is big, elasticity is good, be simple to manufacture, rigidity is small
Point.It is suitable for bearing general work pressure for making, to the metal hose of flexible more demanding big or middle latus rectum.Helicon wave
Line pipe is the diaphragm outer rim and the semicircular ring phase cut-grafting centripetal around the concave surface of spring shape around spring shape of certain length, inner edge with around spring shape
Concave surface vest semicircular ring phase cut-grafting particular geometry pipe.This kind of bellows is high with intensity, rigidity is big, manufacture
The features such as simple is suitable for requiring flexibility general, higher high, the middle pressure of intensity requirement, the metal of middle or small latus rectum for making
Hose.
It, generally can be using in two phases in the prior art in order to enable metal hose to reach more ideal damping effect
Mutually nested bellows, and vibration-absorptive material is set in two bellowss, or installs a plurality of small-sized ripple arranged side by side in net cover
Pipe, to reach further damping effect, two bellowss of the first scheme will cause during bending it is uncoordinated, and
Also it can affect to curved angular range, second scheme not only causes biggish shadow to bending angle range
It is loud, simultaneously because the internal diameter of bellows becomes smaller and the quantity of bellows becomes more, subsequent installation and use are all brought
It is inconvenient.
Summary of the invention
In view of the above-mentioned problems, specific structure is as follows the present invention provides a kind of corrugated flexible metal tube with shock-absorbing function:
A kind of corrugated flexible metal tube with shock-absorbing function, which is characterized in that including ring metal bellows and be welded on
The connector at its both ends, the outside that the ring metal bellows are located at each wave crest are cased with a cricoid metal-coating, the gold
Belong to and be filled with a fiberglass cloth between housing and ring metal bellows, a gold medal is provided with outside ring metal bellows
The weld at category net cover, the metal net cover and both ends is fixed.
Further, the metal-coating is welded by two semicircle snap rings.
Further, a rubber layer, the glass fabric are cased in the outside of the ring metal bellows crest location
The outside that layer passes through rubber layer described in resin adhesion.
Further, the gap between the ring metal bellows and metal-coating is filled by the rubber layer.
Further, the wave crest of the ring metal bellows is equipped with multiple recesses, and the inside of the rubber layer is equipped with packet
The groove of the wave crest is wrapped up in, multiple protrusions with mating recesses are equipped in the groove.
Compared to the prior art compared with, the present invention in be socketed respectively by each crest location in a ring metal bellows
Endless metal housing while further improving damping effect, will not impact the bending of bellows, pass through simultaneously
Glass fabric is set in the inner cavity that metal-coating and bellows are constituted, improve bellows crest location and metal-coating it
Between lubricity, will not cause during bending the generation of housing and bellows wear, increase service life, further exist
Rubber ring is set in its inner space to make to have certain elasticity between housing and bellows, to further reduced inside
It is lost caused by friction, while utilizing the insulating properties of glass fabric, it is therefore prevented that rubber ring generates electrostatic in friction process and makes
At accident.
