Abstract
The utility model relates to a novel ventilating channel. An outer layer is a protection enhancing layer, an inner layer is an inner liner layer, and a heat insulation and noise elimination layer is arranged between the protection enhancing layer and the lining layer. The utility model which integrates multiple functions of heat insulation, noise elimination, fire prevention, moisture protection, sound insulation, etc. has the advantages of high intensity, simple manufacturing process, convenient connection, broad raw material sources, low cost, corrosion resistance, light weight and clean and beautiful appearance. In addition, heating equipment is not needed during machining.
Description
The utility model relates to a kind of ventilation duct, particularly a kind of ventilation duct of the new structure that is composited by multiple material.
Be used for the ventilation duct that ventilation duct on the engineering such as central air-conditioner is generally the iron sheet material, the ventilation duct that adopts plexiglass steel or inorganic glass fiber reinforced plastic material to make is also arranged, all there are some defectives to some extent in these ventilation ducts.As iron sheet air channel noise height, be not incubated, easily dewfall is perishable, and the ventilation duct that is used for air-conditioning equipment increases the air-conditioning equipment energy consumption.Organic or inorganic glass fibre reinforced plastics air channel has overcome some defective in iron sheet air channel, but has also that thermal insulation property is poor, intensity is not high and problem such as fireproof performance difference.
Also use a kind of ventilation duct with insulation, noise elimination function in the market, its matrix adopting insulation muffler material is made, and adds the maintenance level that one deck is made of aluminum foil material on pipeline outer wall.This ventilation duct good heat insulating, the noise elimination effect is arranged, but intensity is not high, in the connection process in air channel, as the air channel of extending then needs to install the reinforced structure that reinforcing bar etc. is made, complex manufacturing technology, and work in-process need use heating equipment, this air channel fireproof performance is not ideal enough simultaneously, can only adopt plug in structure between the pipeline.
The purpose of this utility model provides a kind of multi-functional ventilation duct, this ventilation duct can overcome the defective of iron sheet material commonly used, organic or inorganic glass fibre reinforced plastic material ventilation duct, also can solve the deficiency of present insulation silence type air channel at aspects such as fire prevention, noise elimination, insulation, intensity, it is multi-functional to have insulation, noise elimination, fire prevention, protection against the tide, sound insulation, high strength etc.
The purpose of this utility model realizes by following structure: the structure of this air duct wall comprises three layers, and the mesosphere is coated with the protection enhancement layer for the insulation silencing plate at the outer surface that is incubated silencing plate, at the bonding inside liner of internal surface of insulation silencing plate.
The protection enhancement layer adopts inorganic material to make; Inside liner adopts asbestos or fiberglass braided thing to make.
Mesosphere of the present utility model adopts fiber-like material to make the insulation silencing plate, have good insulation, sound insulation, noise elimination function, outermost protection enhancement layer has improved the intensity of ventilation duct, pipeline body connects can adopt grafting, also can adopt flange to connect, need not to join in addition other materials (as steel part etc.).Because the intensity height makes the air channel can stiffening device be set because of the length in air channel in the connection process.
The utility model has the advantages that: it is multi-functional to integrate insulation, noise elimination, fire prevention, protection against the tide, sound insulation etc., the intensity height, and construction process is simple, does not need to use heating plant in the processing, easy to connect, the raw material wide material sources, cost is low, corrosion-resistant, in light weight, external form is clean and tidy, attractive in appearance.
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
In the present embodiment, the outermost protection enhancement layer of multi-functional ventilation duct (1) is to adopt inorganic material to make, as concrete, magnesia cement, silicate etc.; The mesosphere is to be made by fiber-like material for insulation silencing plate (2), and insulation, the cold insulation performance is good, and noise is low, but and noise reduction sound; Innermost layer is inside liner (3), adopts asbestos or fiberglass braided thing to make, and its effect is the fibre shedding that prevents to be incubated silencing plate.
During pipeline body is made, earlier inside liner (3) is bonded on the internal surface of insulation silencing plate (2), the insulation silencing plate that bonding is good is made required shape, size, and the outer surface at insulation silencing plate (2) applies the protection enhancement layer of being prepared by inorganic material (1) again.During construction, as required pipeline body is coupled together, no matter adopt inserting mode to connect or the flange connection, all very convenient, need not adopt other equipment or annex.
Multi-functional ventilation duct is used for the air channel of air-conditioning equipment, can improve the cooling effectiveness of air conditioner, energy efficient.The making shape in air channel can be square, cylindrical shape or other required forms.
Claims (3)
1, a kind of multi-functional ventilation duct, the structure of tube wall comprises three layers, it is characterized in that: the mesosphere is insulation silencing plate (2), is coated with protection enhancement layer (1) at the outer surface that is incubated silencing plate (2), at the bonding inside liner of internal surface (3) of insulation silencing plate (2).
2, multi-functional ventilation duct according to claim 1 is characterized in that: protection enhancement layer (1) adopts inorganic material to make.
3, multi-functional ventilation duct according to claim 1 is characterized in that: inside liner (3) is to be made by asbestos or fiberglass braided thing.
