Abstract
The utility model belongs to a flame-resistant silencing energy saving wind pipe commonly used for ventilating air conditioners. The utility model which is suitable for all kinds of ventilating ducts of the engineering of the ventilating air conditioners is characterized in that an inner layer can be a flame-resistant glass fiber reinforced plastic wind pipe bonding layer or can be a glass fiber cloth bonding layer; a middle layer is a heat preservation silencing layer; an outer layer is an inorganic glass fiber reinforced plastic casing, wherein, both ends of which are matched with connecting flanges; the wind pipe and the flanges are shaped for one time through a mold to be made into a heat preservation type or a non heat preservation type. The wind pipe has the advantages of smooth surface, steel plate saving, zero air leakage rate, zero heat and cold radiation quantity of the pipe wall, superior price to a tinplate plus a heat preservation device and a silencer, silencing, sound insulation, ageing resistance, corrosion resistance, uniform thickness and long service life. The utility model can be the ideal substitute of the existing tinplate wind pipes, organic glass reinforced plastic wind pipes and plastic wind pipes at present.
Description
At present, China's central air-conditioning system, ventilation system, fume-resisting system, drum induced draught system be along with its development of modernization construction is more and more faster, and essential in large, medium and small public and China Democratic National Construction Association builds.But, the selection problem of air-conditioning, ventilation, drum air inducing and anti-gas exhaust duct, HVAC Designers of designing institute and users are generally reflection all, the iron sheet airduct is perishable, the life-span is short, inleakage is big, waste energy, perspex steel airduct and plastics airduct easy firing and reason such as easily aging do not meet rules such as Building Fire Protection standard.Wrapping is not tight between thermal insulating material and the air channel outer surface, produces thermoconvection, gapped thermal resistance.Therefore, China's air conditioner ventilation energy consumption and waste of raw materials are serious, and its economic benefit, environmental benefit and social benefit can not reach design, construction and user's requirements at the higher level.
The utility model (figure one) has overcome all problems in present domestic old air channel, according to the regulation of " state architectural design fire regulation " 9.3.12 bar and " high-rise building design and fire regulation " 8.5.6 bar, manufactured experimently out and do not fired fully every the energy-saving silencing airduct.This airduct in course of working with optimized IWS International Workman Standard reach that smooth surface, sanitary condition are good, to reach air leak rate of air curtain be 0 to energy conservation standard, save metallic material more than 98%, price is better than galvanized sheet iron and adds insulation and silencing apparatus: can eliminate the noise and also can insulate against sound, and ageing-resistant, consistency of thickness; Glass cloth does not have layering not have the zone of fracture defective yet, and it is better than perspex steel mechanical strength properties; The heat radiation of tube wall and the cold scattering amount is minimum, proportion is lighter, indeformable, be A level noncombustible construction fire proofing material, the life-span is long, high temperature resistantly reaches 750 ℃, low temperature resistant-50 ℃; Finished product is nonpoisonous and tasteless, this material succeed in developing environmental protection to the whole mankind, energy-conservation, substitute existing similar building materials, it rationally uses the green low-loss materials of nature, restriction is used repeatedly to smelt and is polluted high consumption material, retain the leeway of sustainable development to the descendants, its social benefit, environmental benefit and economic benefit all are one of the most considerable building materials.Purpose of the present invention that Here it is.
Below the utility model is elaborated:
Of the present utility model the combustion every energy-saving silencing airduct (seeing figure one) is made up of noise elimination heat-insulating fiberboard 1, internal layer 2, outer unorganic glass box hat 3 and unorganic glass steel flange 4.This does not fire every the energy-saving silencing airduct and can cause heat insulation type pipe and non-heat insulation type pipe, can cause silence type pipe and non-silence type pipe yet.
Noise elimination heat-insulating fiberboard (1) is by 5,6,7 ... arbitrary thickness, width, length and the density of 100mm is all difficult sheet materials that fire, do not fire the insulation muffler material such as glass fibre cotton plate, asbestos slate, rock cotton board, mineral wool board, the resin expanded plate of difficult combustion, self-extinguish ability styrofoam, aluminium silicate wool plate arbitrarily.Need not be incubated in the time of need not eliminating the noise and not add noise elimination insulation fibre sheet material (1).Make shapes such as rectangle, square, straight tubular, 90 degree elbow-shaped, flaring convergent shape, hemispherical dome shape, threeway and four-way shape.
Internal layer (2), by not firing or any and ammonium chloride of difficult combustion glass fibre cloth, any hardness of steel that helps improving airduct such as magnesium oxide, all chemical compositions of gentle threading property and fireproof performance are assigned in bittern, making its thickness is 1mm, 1.1mm, 1.2mm ... glass fibre reinforced plastic blast pipe is fired or do not fired to any difficulty within the 10mm, or use one deck, any method of layer glass silk cloth, by the fire prevention glue bond on noise elimination fibrous type sheet material (1) surface, non-insulation pipe can not add internal layer (2), causes rectangle, square, straight tubular, 90 degree elbow-shaped, flaring convergent shape, hemispherical dome shape, shapes such as threeway and four-way shape.
Outer unorganic glass box hat (3), by difficulty combustion, do not fire glass fibre cloth and be assigned in bittern with any all chemical compositions that help improving the hardness of steel of airduct, the threading property that softens and fireproof performance such as ammonium chloride, magnesium oxide, make its thickness and can be 1mm, 1.1mm, 1.2mm ... arbitrary thickness of 20mm.Also can not adorn noise elimination wad (1) and internal layer (2) in the time of need not being incubated and eliminating the noise, make shapes such as rectangle, square, straight tubular, 90 degree elbow-shaped, flaring convergent shape, hemispherical dome shape, threeway and four-way shape.
Unorganic glass steel flange (4), its materials, chemical formulation and processing method are identical with unorganic glass box hat (3), with unorganic glass box hat one single forming, thickness is 1mm, 1.1mm, 1.2mm ... any of 50mm made shapes such as rectangle, square, circle.Fig. 1-detailed description: 1 noise elimination heat-insulating fiberboard, 2 internal layers, 3 outer unorganic glass box hat 4 unorganic glass steel flanges
