Embodiment
In the accompanying drawings, same or similar element is represented or with same or like function using same or similar label
Element.Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
In description of the present utility model, term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear", "left", "right", " perpendicular
Directly ", the orientation or position relationship of the instruction such as " level ", " top ", " bottom " " interior ", " outer " are based on orientation shown in the drawings or position
Relation, is for only for ease of description the utility model and simplifies description, rather than indicate or imply that the device or element of meaning must
There must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to the utility model protection domain
Limitation.
As depicted in figs. 1 and 2, the corrugated flexible hose that the present embodiment is provided includes bellows body 1 and insulating 2, its
In：
Insulating 2 is wrapped in the lateral wall of bellows body 1, by insulating 2, has to corrugated flexible hose body 1
Heat-insulated and insulation effect, therefore effectively prevent from being arranged in the parts near blast pipe corrugated flexible hose by high-temperature baking, occur
Damage of components phenomenon, reduces component failure rate.
But, insulating 2 can not influence the flexibility that bellows body 1 has itself, therefore, and insulating 2 is by energy
The malleable material for enough making bellows body 1 freely stretch is made, such as woven materials, and woven materials can be well adapted for ripple
The telescopicing performance of line body 1, it is ensured that bellows body 1 freely stretches.Even if that is, be additionally arranged insulating 2, also not shadow
The flexibility that bellows body 1 has in itself is rung, and then can effectively absorb the vibrational energy of blast pipe, reduces the vibration of blast pipe,
Blast pipe is prevented to be broken.Certainly it is all that there is ductility, it is necessary to which explanation, insulating 2 is not limited to woven materials
And can reach that the material of heat-insulation and heat-preservation can be used.The insulation feelings that the thickness of insulating 2 mainly reaches as needed
Condition is determined.
In one embodiment, the corrugated flexible hose also includes layer of silica gel 3, and layer of silica gel 3 is formed in the outer of insulating 2
Surface.By the outer surface packaging silicon rubber layer 3 in insulating 2, the heat-insulation and heat-preservation of insulating 2 can not only be ensured
Can, additionally it is possible to prevent insulating 2 from making moist or because the reduction service life such as dust.
In one embodiment, the corrugated flexible hose also include metal net cover 4, metal net cover 4 be located at bellows body 1 with every
Between hot heat-insulation layer 2, so that insulating 2 can smoothly be wrapped in the bellows body 1, bellows body can also be increased
1 reliability.Specifically, metal net cover 4 is pressed to outside bellows body 1 by compaction techniques, and the internal diameter of metal net cover 4 is equal to ripple
The external diameter of line body 1, width is identical with the straightway width of bellows body 1, to envelope bellows body 1 completely.
In one embodiment, the corrugated flexible hose also includes the first outer shroud 5, and the first outer shroud 5 is arranged in the way of press-fiting
