Description
Technical Field
The utility model relates to a flexible air pipe, in particular to a flexible air pipe with a high-strength maintenance external cylindrical structure.
Background
In the use of current flexible tuber pipe, because of inside and outside pressure and outside collision, easily lead to unable the restoration of original state after the tuber pipe indent warp, influence appearance pleasing to the eye and interior passageway ventilation performance. In the applicant's prior application, prevent that the body circumference warp through setting gradually the multiturn steel wire circle in the tuber pipe, but in logical long tuber pipe structure, still have indent deformation hidden danger in the steel wire circle interval distance, simultaneously at steel wire rope long-term bearing of steel wire circle position circumference structure, easy circumference structure warp to the steel wire circle is difficult to resume after being pressed or collision deformation, thereby leads to the tuber pipe to correspond the shape after the external structure deformation of a plurality of steel wire circles different, influences whole harmony pleasing to the eye.
Disclosure of Invention
The utility model provides the flexible air pipe which has a simple structure, can effectively support the flexible air pipe body to keep a circumferential shape, can recover automatically or is convenient for external auxiliary recovery, and has high strength and maintains an external cylindrical structure.
The technical scheme adopted by the utility model is as follows: a high-strength flexible air pipe with an external cylindrical structure is maintained, which is characterized in that: the tube plate is wound into a tube-shaped tube body structure and comprises an inner fireproof fiber cloth layer, a glass wool layer, a hard fireproof net and an outer fireproof fiber cloth layer, wherein the glass wool layer is bonded on the inner fireproof fiber cloth layer, the hard fireproof net is bonded on the glass wool layer uniformly distributed at multiple points through fireproof fiber lines, and the outer fireproof fiber cloth layer is bonded on the hard fireproof net.
And the inner wall of the inner fireproof fiber cloth layer and/or the outer wall of the outer fireproof fiber cloth layer is/are coated with a fireproof silica gel coating.
The inner fireproof fiber cloth layer and/or the outer fireproof fiber cloth layer are/is fiber cloth impregnated with fireproof silica gel coating.
The hard fireproof net is provided with net edges at the lateral sides of the width direction of the tube plate.
And the joint point of the hard fireproof net and the glass wool layer is positioned at the intersection point of the grid.
The hard fireproof net is an elastic metal net or a nylon net.
The elastic metal net is an elastic alloy net.
The elastic alloy net is a copper-based alloy.
The outer layer of the hard fireproof net is sewn with the fireproof felt through fireproof fiber threads at multiple points, and the fireproof felt is externally glued with an outer fireproof fiber cloth layer.
The glass wool layer is replaced by a fireproof felt.
The beneficial effects of the utility model are as follows:
1. the hard fireproof net is used as a recoverable layer, copper-based alloy and nylon net with good elastic coefficients are preferable, and the air pipe can recover by itself or recover by positive pressure after internal ventilation or recover by external suction cup action by external pulling of the outer fireproof fiber cloth layer when concave deformation is generated by internal and external pressure or external collision.
2. The hard fireproof net is not glued with the upper and lower glass cotton layers and the fireproof felt, and is sewn by fireproof fiber lines, so that the inner layer structure can be prevented from being torn and loosened during various impacts or compression deformation and resetting, and the effective recovery under various special-shaped deformation is ensured. The positions of grid points of the hard fireproof net are sewn, the integral connection firmness is improved, and meanwhile reset stability after deformation is ensured.
