Abstract
The utility model relates to a heat insulating noiseless air tube, which is composed of a tube wall and an interface. The utility model is characterized in that the tube wall is an ultra-fine glass fibre board. Glass fibre cloth composite aluminium foil is stuck on the inner part and the outer part of the glass fibre board to form an outer protective layer and an inner lining layer of the tube wall. The interface of the tube wall can be in female tenon connection, or in male tenon connection, or in flange connection, or in inserting board bar connection. The outer protective layer of the tube wall can be a galvanized steel board or a wire-mesh reinforced inorganic glue solidified layer. The inner lining layer can be micropore glass fibre cloth composite aluminium foil. When the long edge of the tube wall is greater than 1000 millimeters, a frame is arranged on the outer side of the tube wall for reinforcement, or a sound absorption sheet is arranged in the air tube. The utility model is suitable for a ventilation air-conditioning pipeline in the building engineering.
Description
The utility model belongs to construction work air conditioner pipeline, particularly has the pipeline of insulation, noise elimination function.
The existing air conditioner pipeline that is used for construction work is made up of tube wall, interface, and tube wall is the glass plate, according to instructions for use glass wool cloth in the tube wall liner, outsourcing glass wool cloth aluminium foil.This pipeline can satisfy general air conditioner ventilation, but discomfort should have requirement protection against the tide, the higher ventilating duct of requirement for anticorrosion.
The purpose of this utility model provides a kind of novel Heat insulating noiselss air duct, and this airduct integrates insulation, noise elimination, waterproof, protection against the tide, anticorrosion, and material is light, processing is simple, installs fast.
Heat insulating noiselss air duct of the present utility model, form by tube wall, interface, tube wall is the glass plate, outsourcing glass wool cloth aluminium foil, glass inner-lining silk cloth, it is characterized in that: tube wall is a super-fine glass fiber board, at the gluing glass fabric clad aluminum foil that connects that the inside and outside usefulness of glass plate has fire prevention, water resistance, forms the outer jacket and the inner liner of tube wall; The tube wall interface is the yin, yang joggle.
The unit weight scope of described super-fine glass fiber board is at 48 kilograms/cubic metre～90 kilograms/cubic metre.
Described tube wall outer jacket can adopt galvanized steel plain sheet, or the inorganic glue liquid cured layer of gauze wire cloth reinforcement, when adopting galvanized steel plain sheet, at the two ends of tube wall " U " shape galvanized steel plain sheet blast cap is set, and is connected and fixed by rivet and outer jacket degree zinc steel plate, forms airduct.
Described tube wall inner liner can adopt micropore glass cloth clad aluminum foil, and perforated percentage is 1～2%.
Described tube wall interface can be that flange connects, also can adopt the plate bar to connect, connected mode is: the inboard, termination at tube wall is fixed with the safe edge angle bar, and arranged outside does not wait the long trough fixed connecting piece, the long limit of flute profile is connected with angle bar by screw, the opening plate bar of pegging graft on the minor face of flute profile.
Described airduct cross section can be rectangle or polygon or trapezoidal according to instructions for use.
When described tube wall is grown the limit greater than 1000 millimeters, can around the tube wall outside, steel plate bar frame strengthening be set; Also the sound-absorbing sheet can be set in airduct, the sound-absorbing sheet is a glass plate two sides adhering glass cloth clad aluminum foil, and connected mode is when being glass cloth clad aluminum foil with the tube wall outer jacket, and one " U " shape galvanized steel plain sheet blast cap is set on tube wall, fix by bolt and tube wall, the sound-absorbing sheet inserts in the blast cap; When the tube wall outer jacket is galvanized steel plain sheet, fix one " U " shape galvanized steel plain sheet blast cap by rivet on tube wall outer jacket galvanized steel plain sheet, the sound-absorbing sheet inserts in the blast cap.
Airduct preparation method of the present utility model is: earlier the compound upper glass cloth of special fire-proof and water-proof adhesive specially aluminium foil is adopted on glass plate two sides, make the composite glass fiber plate of two-sided composite glass fiber cloth aluminium foil; Adopt dedicated tool with the cutting of composite glass fiber plate then, fluting, mortise, rubber cement, rubber belt sealing become pipe.
When being steel plate,, inlaying and be fixed on the steel plate, and then become pipe at first with after the blanking of composite glass fiber plate as outer jacket.
Heat insulating noiselss air duct of the present utility model, because sheath adopts glass cloth aluminium foil or micropore glass cloth clad aluminum foil to make, can prevent thoroughly that glass from dispersing, cleanliness factor is higher, the airduct resistance is little, need not to do insulation layer again, the damp proof insulation layer, have the effect of protection intermediate layer, can save or reduce sound absorber simultaneously; And the ectonexine of airduct is glass cloth aluminium foil; make it have good airtight damp proof insulation effect; can make that insulation, noise elimination intermediate layer--what the glass flaggy was stable keeps dry state; when outer jacket adopts galvanized steel plain sheet; the effect of playing protection and strengthening, thus can guarantee that airduct has excellent insulating, acoustic attenuation performance.
Heat insulating noiselss air duct of the present utility model is applicable to ventilation and air conditioning engineering, is used to the pipeline that is incubated, eliminates the noise, and this pipeline processing technology is simple, is fit to field fabrication.
