Abstract
The utility model provides a composite glass wool wind pipe, which comprises an inner centrifugal glass wool, a middle steel net layer and an outer centrifugal glass wool, wherein the inner centrifugal glass wool and the steel net are combined by caking binder, the outer centrifugal glass wool is fixed on the steel net by clip and snap ring, the clip are connected with the steel net by the blinder, the inner surface of the inner centrifugal glass wool and outer surface of the outer off center glass wool are all pasted with aluminum foil. The utility model is of good heat preservation and wind direction function, but low price. The wind pipe not only saves material and reduces cost, but also decreases the self weight of the wind pipe, which is convenient for transport and construction. The utility model is extensively used in a heating and air conditioning system.
Description
Technical field
The utility model relates to a kind of airduct of Heating,Ventilating and Air Conditioning (HVAC) ventilation usefulness, the cotton airduct of particularly a kind of composite glass.
Background technique
Along with developing rapidly of central air-conditioning system, overcome the shortcoming or the deficiency of existing equipment and material, constantly improve and how to reduce its cost when improving its performance and seemed more and more important.In price of steel product surging today, material-saving is exactly the direct embodiment of Economy.Airduct is as link important in the middle of the air conditioner ventilation equipment, and its material capability and relationship between quality the operational effect of whole ventilation and air conditioning system.The problem that airduct exists can cause the air output deficiency, and inleakage surpasses code criteria, causes energy waste, heat source insufficiency and air conditioner ventilation engineering operation instability.
China's airduct now commonly used mainly contains the galvanized sheet iron airduct, unorganic glass airduct, three kinds of composite glassfibre air ducts at present.
1, galvanized sheet iron airduct: adopt galvanized sheet iron processing, the conveying of the general gas that only suitable water content is little is easily got rusty, and does not have insulation and acoustic attenuation performance, must add bag thermal insulation layer and heat preservation protective layer in addition, and silencing apparatus must be set, and makes, installation period is long.
2, inorganic glass fibre reinforced plastic blast pipe: adopt glass fibre to strengthen inorganic material and make, but more crisp, it is yielding influenced by deadweight greatly for proportion, hardness, is subjected to the raw material preparation to influence and restrict easy shortcake and splits, and makes, installation period is long.Because of its have fire prevention, anticorrosion, every the advantage of making an uproar, make it once once seize more than half airduct market.But in recent years As time goes on, people have gained some understanding to some weakness and the deficiency of inorganic glass fibre reinforced plastic blast pipe gradually.As the time stability of moisture proofness and each capability and performance of product of reality, promptly As time goes on, the speed of its every decreased performance is faster than expection, and especially influenced by the raw material proportioning bigger for its inherent quality, and be difficult for going out to the eye in the actual engineering.
3, composite glass fiber plate airduct: the centrifugal glass plate with unit weight 64kg/m3, thickness 25mm is a base material, interior multiple glass fibre cloth, outer multiple moistureproof aluminium foil cloth, behind special fireproof Bond composite drying, make through technology such as cutting, fluting, bonding and reinforcement again, have noise elimination, insulation, fire prevention, protection against the tide, inleakage is little, material is light, easily construction, save advantages such as installing space.But cost is higher, should not use under the higher occasion of ambient humidity, should not make the large scale airduct.
Summary of the invention
The purpose of this utility model is to provide a kind of composite glass cotton airduct, and under the prerequisite that does not reduce the airduct performance, this airduct has economical with materials and reduces cost, and alleviates deadweight advantage easy for installation.
In order to achieve the above object, the utility model adopts steel wire to replace iron sheet to do the airduct liner, has saved material and has reduced cost; Lay the simple glass cotton at the steel wire inner and outer surface, both guaranteed good wind-guiding performance, improved the thermal insulation and the erasure effect of airduct again.
Description of drawings
Below in conjunction with accompanying drawing, the structure of the cotton airduct of the utility model composite glass is described in further detail.
Fig. 1 is the utility model explosion views.
Fig. 2, Fig. 3 are the utility model structural profile view.
Embodiment
Referring to Fig. 1,3 is the steel wire with certain intensity, as airduct liner skeleton, 1 is the internal layer centrifugally glass-wool, and the inwall of the steel wire 3 that is laid in is combined with each other internal layer centrifugally glass-wool 1 and steel wire 3 with binder, 5 is outer centrifugally glass-wool, the outer wall of the steel wire 3 that is laid in.Referring to Fig. 2, paste one deck aluminium foil 7 at the internal surface of internal layer centrifugally glass-wool 1, the outer surface of leafing heart glass wool 5 is pasted one deck aluminium foil 6 outside.One deck aluminium foil 7,6 that paste on inside and outside leafing heart glass wool 1,5 and their surfaces has not only improved the heat-insulating property of airduct, and has played sound deadening.Referring to Fig. 3, the outer centrifugally glass-wool 5 of aluminium foil 6 is pasted on steel wire 3 outer walls that are laid in, surface, and the effect through being bonded in the bail 2 on the steel wire 3 and being positioned at the snap ring 4 on the outer surface aluminium foil 6 is fixed on the steel wire 3.The thickness of outer centrifugally glass-wool 5 is generally according to the insulation requirement and the environmental conditions setting of airduct, and the thickness of internal layer centrifugally glass-wool 1 is less than 20 millimeters, and the order number of steel wire 3 is less than 20.
Beneficial effect
The utility model composite glass wool wind pipe adopts centrifugally glass-wool to paste one deck aluminum foil material, has Good insulation and guide performance while, price is cheap a lot; Substitute galvanized sheet with steel wire and make the liner bone Frame has not only been saved material, has been reduced cost, and has greatly alleviated the weight of airduct self, conveniently removes Fortune and construction.
