Abstract
The utility model discloses a kind of noise reduction heat preservation ventilating pipes, including aluminium foil layer and layer of PVC, sound insulation cotton layer is provided between the aluminium foil layer and layer of PVC, interior noise reduction hole is provided on the aluminium foil layer, the layer of PVC is provided with outer noise reduction hole, the interior noise reduction hole extends to sound insulation cotton layer by aluminium foil layer, the outer noise reduction hole extends to sound insulation cotton layer by layer of PVC, the interior noise reduction hole and outer noise reduction hole are successively arranged alternately horizontal and vertical, the utility model adds sound insulation cotton layer in ventilation duct, and in inside and outside punching to sound insulation cotton layer, form noise reduction hole, the internal noise generated can be absorbed by reaching wind interior noise reduction hole in internal flow, outer noise reduction hole can absorb indoor noise simultaneously, increase ventilation duct action function.
Description
Technical field
The utility model belongs to ventilation duct field, more specifically to a kind of noise reduction heat preservation ventilating pipe.
Background technique
For ventilation duct commonly used to be mounted on indoor roof used in ventilation, generalling use internal layer is aluminium foil layer,
It when aluminium foil layer is soft layer, needs to be supported using spiral wire, without support when aluminium foil layer is hard, be used in outer layer
Layer of PVC carries out one layer of protection, but when wind flows in pipeline, and generating friction with aluminium foil layer has noise, is especially more pacifying
This noise is particularly evident in stationary ring border.
Utility model content
In view of the deficiencies of the prior art, the utility model provide it is a kind of add sound insulation cotton layer in ventilation duct, and
Inside and outside punching forms noise reduction hole, inside can be absorbed by reaching wind interior noise reduction hole in internal flow to sound insulation cotton layer
The noise of generation, while outer noise reduction hole can absorb indoor noise, increase ventilation duct action function, and sound-proof material can reach
To the noise reduction heat preservation ventilating pipe of part heat insulation effect.
To achieve the above object, the utility model provides following technical solution: a kind of noise reduction heat preservation ventilating pipe, including aluminium
Layers of foil and layer of PVC are provided with sound insulation cotton layer between the aluminium foil layer and layer of PVC, interior noise reduction hole, institute are provided on the aluminium foil layer
It states layer of PVC and is provided with outer noise reduction hole, the interior noise reduction hole extends to sound insulation cotton layer by aluminium foil layer, and the outer noise reduction hole is by layer of PVC
Extend to sound insulation cotton layer.
The further interior noise reduction hole and outer noise reduction hole are successively arranged alternately horizontal and vertical.
Compared with prior art, the utility model has the beneficial effects that interior noise reduction hole can effectively absorb consumption wind logical
The vibrating noise generated when flowing in air hose, at the same the application of this ventilation duct indoors when, outer noise reduction hole can be by indoor noise
Absorption consumption is carried out, the degree that sound reflects indoors is reduced, realizes multifunctional usage, while sound-proof material itself has centainly
Heat insulation effect avoids and external heat exchange in relatively long distance air-supply；Wherein interior noise reduction hole and outer noise reduction hole alternate setting,
Can be avoided the existing interior noise reduction hole of same place of sound-proof material also have outer noise reduction hole and cause herein sound-proof material it is relatively thin.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of the utility model noise reduction heat preservation ventilating pipe；
Fig. 2 is the utility model noise reduction heat preservation ventilating tube portion unfolding state figure.
Appended drawing reference: 1, aluminium foil layer；2, layer of PVC；3, interior noise reduction hole；4, outer noise reduction hole；5, sound insulation cotton layer.
Specific embodiment
The embodiment of the utility model noise reduction heat preservation ventilating pipe is described further referring to Figures 1 and 2.
A kind of noise reduction heat preservation ventilating pipe, including aluminium foil layer 1 and layer of PVC 2, are provided between the aluminium foil layer 1 and layer of PVC 2
Sound insulation cotton layer 5 is provided with interior noise reduction hole 3 on the aluminium foil layer 1, and the layer of PVC 2 is provided with outer noise reduction hole 4, the interior noise reduction hole
3 extend to sound insulation cotton layer 5 by aluminium foil layer 1, and the outer noise reduction hole 4 extends to sound insulation cotton layer 5 by layer of PVC 2, wherein drop in preferred
The make an uproar surface in hole 3 and outer noise reduction hole 4 is respectively aluminium foil and PVC, i.e. sound-proof material is not contacted with inside and outside directly.
The preferred interior noise reduction hole 3 of the present embodiment as shown in Figure 2 and outer noise reduction hole 4 successively replace horizontal and vertical
Setting, i.e., when ventilation duct is launched into plane, the four direction up and down in each interior noise reduction hole 3 is outer noise reduction hole 4,
Similarly the four direction up and down in each outer noise reduction hole 4 is interior noise reduction hole 3, and interior noise reduction hole 3 and outer noise reduction hole 4 are not
Solid line hole is outer noise reduction hole 4 in the same place of sound-proof material, figure, and dotted line is interior noise reduction hole 3.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
