Abstract
The utility model discloses a conjoined flange composite plate air duct. The aim of the utility model is to provide a conjoined flange composite plate air duct with simple process, convenient and rapid installation, high strength, heat preservation, corrosion protection, dewfall prevention, good sealing property, low cost, long lifetime and stable quality. The utility model is formed by the connection of each section of the air pipes of quadrate composite plates, flanges and screw bolts. The air pipes and the flanges adopt the composite plates to conjointly shape, and the peripheral wall of the two ends of the air pipe and the outer surface of the flange are provided with a flange sheath which is fixedly connected. The utility model satisfies the requirement of the composite plate air duct to the connecting structure of the composite air pipe in a high-medium pressure system and an air-purifying system. The utility model can be widely applied to various air conditioning systems and ventilating fields.
Description
Technical field
The utility model relates to the used ventilation shaft of a kind of central air-conditioning and ventilation field, particularly relates to the ventilation shaft of composite board.
Background technology
Be applied to the air channel of Air-conditioning Engineering in the prior art, generally many employing steel plate wind pipe, zinc-plated skin airduct and glass fibre reinforced plastic blast pipes, though these several airduct intensity height, construction is heavy, the installation trouble, and does not have insulation, noise elimination function, while anti-condensation ability.The work that this air channel installs heat-insulation layer additional is mostly finished under work high above the ground, and inconvenient operation, sealing are poor, and energy loss is big.Be applied to the air channel that occurred using composite board on the engineering at present, the fixedly connected mode of the angle iron flange formula of employing is arranged in the connection of each section composite air duct, this structure manufacturing process complexity, cost height, quality instability are easy to generate dead angle, inleakage height in the air channel.The connection that also has a kind of composite air duct is to adopt tenon plug-in type flange type of attachment, though this form is than very big improvement and raising had been arranged in the past, but airduct intensity is low, quality is unstable, still can not satisfy the requirement to the composite air duct syndeton in high pressure system and purification wind system of composite board air channel.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provide a kind of rational in infrastructure, technology is simple, quick and easy for installation, intensity height, anti-condensation, insulation, sealing property are good, long, stay-in-grade coupling flange composite board air channel of low life-span of cost.
The technical scheme that the utility model adopted is: a kind of coupling flange composite board air channel, be to be formed by connecting by each section square composite board airduct, flange and bolt, airduct and flange adopt the moulding of composite board disjunctor, and the two ends of airduct are near a flange sheath is set fixedlys connected on the periphery wall of flange with on the outer surface of flange.
Described flange sheath adopts the section bar of moulding, and the correspondence position of contact-making surface is provided with two retuse strong rubber grooves that add around flange sheath and the flange outer surface.Fixed by rubber cement on described flange sheath and airduct and the flange all-in-one-piece contact-making surface, the contact jaw of flange sheath and airduct is fixed on the periphery wall of airduct by a connection piece.Described flange sheath can adopt shape.Described flange sheath can also adopt plastic material.Described airduct and flange are fixedly coupled part and are made of anti-condensation nut and reinforcing nail.The composite board that described airduct and flange adopt is that the intermediate layer is macromolecular materials such as polyurethane, phenolic aldehyde, glass, and ectonexine is embossing aluminium sheet, aluminium foil cloth material.
The beneficial effects of the utility model are: airduct and flange all adopt the moulding of composite board material disjunctor to form a complete composite board air channel, and it is rational in infrastructure, technology is simple, sealing property is good, and material is light simultaneously, material source abundant, low cost of manufacture.It is low that the airduct internal structure does not have dead angle, high pressure resistant, corrosion-resistant, no dewfall, inleakage.Be convenient to on-the-spot installation, convenient and swift, only need carry out bolting.Employing is provided with flange sheath that two scrobicula shapes add the strong rubber groove and airduct and flange is strengthened fixing, has increased the rigidity that airduct connects and the bulk strength in air channel, not fragile, long service life, steady quality.Satisfied the composite board air channel in the high pressure system with purify in the wind system, can be widely used in various air-conditioning systems and the ventilation field the requirement of composite air duct syndeton.
