Description
Technical field
The present invention relates to fresh air system air hose technical fields, more particularly, to the compound wind of a kind of noise-reducing and heat preservation
Pipe.
Background technique
It is promoted, continuous improvement of people's living standards, thus also had to residential housing quality requirements with the development of science and technology
It is improved.The time of modern humans 80% is to spend indoors, is faced with oxygen content deficiency, air conditioner disease, smoke contamination, haze, first
The puzzlement such as aldehyde, fresh air system(It is commonly called as ventilating system)Be solve air quality a kind of good method, therefore fresh air system by
Gradually it is widely applied.Wherein pipeline is one of air delivery and the main component of distribution in fresh air system, for home dwelling
If building aspect selects bad pipeline to will affect people's lives health instead.It was found that if gas flow rates in air hose
Too fast, the noise of generation is more obviously that when especially environment indoors is arranged in air hose, noise can be also more obvious.If these
Noise problem solves that the physical and mental healths such as people's sleep and work can be seriously affected not in time.It is now by using one kind in the market
Sound insulation coiled material is coated on pipeline outer wall and reaches sound insulation and noise reduction effect.Due in terms of installation, wanting early period first to calculate pipe
The damping foam cotton cut after material perimeter package dimensions carries gum and is pasted onto pipeline outer wall;Then damping will have been glued again
Foam cotton calculates perimeter package dimensions, then cuts the included gum of sound insulation coiled material and be pasted on damping foam cotton it is noted that seam is flat
It is whole.Though the method can play the role of sound insulation and noise reduction, process is tedious for practical application, troublesome in poeration, influences very much construction effect
Rate.
Summary of the invention
The present invention in order to overcome at least one of the drawbacks of the prior art described above, provides a kind of noise-reducing and keeps the temperature compound wind
Pipe.
The present invention is directed to solve above-mentioned technical problem at least to a certain extent.
Primary and foremost purpose of the invention is to propose the effective method for offsetting impact noise caused by air impingement air hose tube wall,
Play sound insulation, heat-insulated, decrease of noise functions.
The further object of the present invention is to realize that tubing is light, heatproof, pressure resistance, and construction and installation are convenient.
In order to solve the above technical problems, technical scheme is as follows:
A kind of composite air duct of noise-reducing and heat preservation, which is characterized in that tubing using three-decker design, including inner tube, in
Interbed pipe, outer tube, the inner tube, middle layer pipe, outer tube mutual extrusion bond to form integration.
This method offsets the noise that internal layer pipe friction vibration issues using the intermediate tube in three-decker, and sky can be effectively reduced
Wind flow shakes noise to the friction of air hose tube wall, and due to the presence of middle layer pipe, can effectively play insulation effect, will be interior
Portion's temperature is obstructed with external temperature.
Preferably, the inner tube, middle layer pipe, outer tube section be ellipse.Tubing uses elliptic design,
On the one hand floor occupied space, convenient transportation and storage space can be reduced, on the other hand, ellipsoidal structure effectively hinders when conveying wind
Hinder eddy flow caused by wind speed, to reduce the impact of tube wall.
Preferably, the noise-reducing and the composite air duct of heat preservation further include several reinforcing ribs, the reinforcing rib setting
Between the inner tube and the outer tube, the inner tube and the outer tube are connected.It can be effective according to the size of tubing
The quantity of reinforcing rib is added and subtracted, effect can effectively be such that internal layer and outer layer uniformly shapes in extrusion molding, in addition can enhance tubing
The compressive resistance of itself, and can fixed support tube diameter ectonexine pipe positional stability.
Preferably, the middle layer pipe carries out processing using macromolecule acoustic material and forms foaming resilient closed cell's formula tubing
Structure, noise caused by capable of effectively offsetting because of internal layer pipe friction vibration, in addition in transmission process, effectively plays insulation effect, will
Internal layer temperature and the temperature of outer layer external environment carry out barrier action.
Preferably, the middle layer pipe uses sponge material, and sponge, which can largely be inhaled, to be changed emitted by wind speed frequency
Acoustic wave energy, can effectively offset because internal layer pipe friction vibration caused by noise, in addition in transmission process, effectively play heat preservation make
With by internal layer temperature and the temperature of outer layer external environment progress barrier action.
Preferably, the inner tube inner tube, middle layer pipe, outer tube use coextrusion forming process, that is, pass through one
Extruder makes inner tube and the disposable extrusion molding of outer tube, then hollow by the tubing that another extruder shapes extruder
Parietal layer gets into foamed material and forms middle layer pipe.After the process, inner tube, middle layer pipe, outer tube are bonded in one
It rises, forms an entirety.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
Elliptic design is used by tubing, reduces floor occupied space, convenient transportation and storage space, and ellipsoidal structure
Effectively eddy flow caused by wind speed is hindered, by three-decker, sky wind to be effectively reduced to reduce the impact of tube wall when conveying wind
Noise caused by the friction to air hose tube wall shakes is flowed, inner tube rubs to shake in three-decker is supported by middle layer pipe
Disappear, the pressure-resistant degree of tubing itself is enhanced by reinforcing rib, macromolecule acoustic material or sponge are used by middle layer pipe, can be reduced
Duct noise and insulation effect can be played.
