Annulus section, the steel annulus section and skeleton iron ring one end are fixed, and the other end is not fixed, and the steel annulus section is exposed described
On cylinder body outer wall, the suspension ring are uniformly arranged on the outer wall of the cylinder, and are integral type structure, adjacent institute with the cylinder
State between suspension ring provided with the 2-4 skeleton iron rings.
As preferred technical scheme, the outer layer and internal layer are respectively flexiplast coated cloth and terylene, the flexibility
The dual anti-films of PVC are scribbled on plastic coated fabric and terylene.
As preferred technical scheme, the inwall of the steel annulus section is provided with convex portion.
As preferred technical scheme, between the adjacent accommodating chamber at intervals of 5cm-10cm, the adjacent skeleton iron
Between circle at intervals of 20cm-30cm.
As preferred technical scheme, pars contractilis is provided with the accent of the accommodating chamber.
(3) beneficial effect
Compared with prior art, it has the advantages that the utility model：Novel flexible rubber of the present utility model
The dual anti-positive pressure wind pipe of glue coated cloth reducing, skeleton iron ring can be slided in cylinder, according to the distance for the point suitably installed
It is different and slide into skeleton iron ring in corresponding accommodating chamber, then change adjusting the half of skeleton iron ring according to tunnel width
Footpath, can preferably adapt to the ventilating engineering in the places such as mine, tunnel that tunnel width is changed greatly, and intensity it is high, flexible,
Tear-resistant, not cracky, long service life, ventilation effect is good.

Embodiment
A kind of dual anti-positive pressure wind pipe of novel flexible rubber coated cloth reducing as shown in drawings, including cylinder 1, skeleton iron ring
2 and suspension ring 3；The cylinder 1 is made up of outer layer 11 and internal layer 12, is uniformly provided between the outer layer 11 and internal layer 12 for placing
The accommodating chamber 4 of the skeleton iron ring 2, the radius of the adjacent accommodating chamber 4 is sequentially reduced, and the skeleton iron ring 2 is provided with breach,
The indentation, there is cased with steel annulus section 5, and the steel annulus section 5 and the one end of skeleton iron ring 2 are fixed, and the other end is not fixed, just
In the radius of regulation skeleton iron ring, the suspension ring 3 are uniformly arranged on the outer wall of the cylinder 1, and are integrated with the cylinder 1
Provided with the 2-4 skeleton iron rings 2 between formula structure, the adjacent suspension ring 3.
Further, the outer layer 11 and internal layer 12 are respectively flexiplast coated cloth and terylene, and terylene has certain bullet
Property, it is ensured that accommodating chamber can adapt to the change of skeleton iron ring radius, and can also recover as former state after skeleton iron ring is removed,
Ensure to scribble the dual anti-films of PVC, antistatic and anti-flammability on original ventilation quality, the flexiplast coated cloth and terylene
