Abstract
The utility model relates to a flanged coupling insulating, silencing ventilating pipe, adopting a glass wool board to insulate against heat, a spraying angle steel to enhance the protection and an aluminum foil tape to seal up. The flanged coupling insulating, silencing ventilating pipe has a better insulating and silencing performance without fibre glass flying, and the mechanical strength of the ventilating pipe is particularly good.
Description
The utility model relates to a kind of ventilation duct of ventilation and air conditioning system.
The iron sheet ventilation duct of prior art though intensity is better, does not have insulation and noise elimination effect.And the problem that the ventilation duct that a kind of composite glass fiber of prior art is made has solved insulation and eliminated the noise, but because the airduct that glass plate (15) is made, intensity and bearing capacity all are significantly less than the iron sheet ventilation duct, can not bear big blast during use.The finished product airduct has collision, friction all to be easy to damage when installation, transportation, storehouse preservation slightly.Particularly edges and corners (11) are very easily damaged without any protection.Secondly the Placement of airduct is to adopt the direct method of plant propagation with cutting (6) of negative and positive birch, and seam crossing is very easily worn the glass problem of dispersing is taken place, and join strength is relatively poor.
The purpose of the utility model patent is that a kind of intensity with iron sheet ventilation duct of design has the insulation of microglass fiber plate ventilation duct, the ventilation duct of noise elimination effect again.Adopt the flange-type connection to be exempted from glass simultaneously and disperse, increase join strength again.
The technical solution of the utility model realizes (2) by accompanying drawing by following measure.
1, at the shortcoming of insufficient strength, this airduct has increased plastic-blasting angle steel (11) as strengthening protection on its rib, link together with the stiffening plate (14) that is connected steel plate (12) and centre of airduct end, forms a protection framework.So both protected airduct, and increased bearing capacity again, (big the length of side＞600mm), portion was aided with stiffening rib (7) within it, to guarantee that airduct can be used for depressing and not deforming, damage than strong wind when the airduct section was big.
2, strengthening measure is taked in the airduct joint: respectively add one deck connecting plate (12) inside and outside glass airduct end, with the wide about 80mm of plate, stretch out the about 30mm of pipe end on it riveting with flange (9), the wide about 50mm of outside plate flushes with pipe end, and same outside plate (12) connects with bolt (13), and therebetween is with composite sheet (15), plastic-blasting angle steel (11) on its rib again be connected steel plate (12) and connect together, make it to form a reinforcing frame, can disperse local pressure, and strengthened in the end.
3, changing socket connection is that flange-type connects.Go up riveting with flange (9) at interior connection steel plate (12); boring bolt (13) connects on the flange; seal with rubber strip between flange; after connecting, sealing is filled with the heat-preservation cotton material in the space of flange plate and pipe end, and height flushes with the airduct appearance; paste layer of aluminum foil belt (4) seal protection on it; this Placement had both guaranteed tightness, heat insulating ability, and intensity also can satisfy, and the problem that glass disperses has not existed yet.
When 4, considering the bright dress airduct of engineering special requirement (figure three), can make its surfacing smooth at the compound one deck glass fibre reinforced plastics of the outer surface of airduct aluminium foil (17), intensity increases.Also increased aluminum alloy frame (16) in addition as the protection web frame, made it not to be afraid of collision bright loading, intensity also can guarantee under special lifting mode; and it is specious; generous, need not what decorate the requirement that just can satisfy bright dress, become a kind of ready-made decoration.
The ventilation duct of making has like this overcome the shortcoming of glass plate insufficient strength, and again owing to adopt flange to connect, having been exempted from glass disperses simultaneously, and sealing easy to connect is strengthened, and eliminates the noise and makes good use of.
Description of drawings: Fig. 1, glass wool ventilation duct structural drawing Fig. 2 of prior art, ventilation duct structural drawing Fig. 3 of the present invention, bright dress noise elimination airduct structural drawing 1 of the present invention, glass cloth 2, centrifugally glass-wool 3, glass cloth aluminium foil 4, aluminum foil and adhesive tape 5, glass cloth aluminium foil 6, joint close 7, stiffening rib 8, bolt hole 9, angle steel flange 10, rivet 11, plastic-blasting steel band angle 12, connect steel plate 13, bolt 14, stiffening plate 15, composite glass fiber plate 16, aluminum alloy square tube 17, the glass fibre reinforced plastics aluminium foil
Claims (3)
1, a kind of insulation, noise elimination ventilation duct of flange-type connection; tube wall is the composite glass fiber plate of being made by the centrifugally glass-wool plate; in its one side compound layer of glass fiber fabric (1); the compound layer of glass fiber fabric aluminium foil of another side (3) forms; it is characterized in that: on its rib, increased plastic-blasting angle steel (11) and constituted the protection framework with the stiffening plate (14) that is connected steel plate (12) and centre of airduct end; being connected of airduct and airduct adopts flange-type to connect (Fig. 2), the appearance of airduct is compound one deck glass fibre reinforced plastics aluminium foil (17)
2, insulation, the noise elimination ventilation duct of a kind of flange-type connection according to claim 1 is characterized in that: respectively add one deck connecting plate (12) inside and outside the airduct end, inner panel stretches out the part riveting of pipe end with flange (9), outside plate flushes with pipe end, inner and outer plates (12) connects with bolt (13), therebetween is with composite sheet (15), connect together with plastic-blasting angle steel (14) and inner and outer plates (12) on the rib, form reinforcing frame.
3, insulation, the noise elimination ventilation duct of a kind of flange-type connection according to claim 1 is characterized in that the connection of airduct is to adopt flange-type to connect; flange is used rubber seal between (9); after connecting; flange (9) is filled sealing with the space of pipe end with the heat-preservation cotton material, pastes layer of aluminum foil belt seal protection.
