Convex end matches connection with the concave character type end of adjacent duct units, and the cross section of the piping unit is rectangle.
By setting vacuum layer, and piping unit size and shape is rationally designed, on the basis of using minimal material, this
The silencing pipeline of utility model has top quality performance muffler.
It is further preferred that said inner tube and the spacing of outer tube are 5mm.
Further, the length of the piping unit is 0.5~2m.
Further, the width of the piping unit is 10~20cm.
The utility model day by rationally designing piping unit length and width, further lifts its erasure effect.
Further, first baffle and second baffle are fixed with said inner tube, on the first baffle and second baffle
Opening is provided with, the first wire netting and the second wire netting, first gold medal are provided between the first baffle and second baffle
Silencing cotton is provided between category net and the second wire netting, is provided with the inner tubal wall between the first baffle and the first wire netting
It is open, opening is provided with the inner tubal wall between the second baffle and the second wire netting.
Further, two openings on the inner tubal wall between the first baffle and the first wire netting are oppositely arranged, institute
Two on the inner tubal wall between second baffle and the second wire netting openings are stated to be oppositely arranged.
The design of said structure, the performance muffler of the utility model piping unit is further increased, further optimize this
The using effect of utility model silencing pipeline, lift Consumer's Experience.
Using above-mentioned technical proposal, including following beneficial effect：The utility model provides a kind of disappearing for VMC
Sound tube road, bimetallic tube is designed to, and effective noise reduction is carried out by laminated vacuum, the utility model rationally designs, so as to get
Silencing pipeline specialty pipeline can be used as in VMC, while when being installed, take small volume, led to
Wind makes final caused noise very small in use, can be cut down significantly to ventilation noise.
