Abstract
The utility model relates to a glass fibre reinforced plastic air channel which belongs to a pipeline class of a ventilation device. The utility model has the technical proposal that a glass fibre reinforced plastic material is adopted as an outer pipe wall layer body in an air channel, an airtight interstice having the function of heat insulation is formed between an inner pipe wall layer and an outer pipe wall layer through flange discs arranged both ends of two pipe wall layers, and the center of the inner pipe wall is the air channel. Because the proposal is adopted, the multifarious technologies required by the traditional heat insulation mode of the pipeline can be spurned, and the utility model is especially suitable for the transportation air channel of a central air conditioner.
Description
The utility model relates to a kind of glass fiber reinforced plastic air channel, especially a kind of air channel of carrying the hot and cold wind of central air-conditioning to use of being used to; Belong to ventilation and heating device class.
In daily being seen central air conditioner system, the conveyance conduit of its hot and cold wind, generally the alloy pipeline by iron or aluminium serves as.Central air-conditioning is lowered the temperature and effective performance of thermal effect in order to reach in installation, lay heat insulating material (as cotton, rock wool or foamed plastics etc.) outside all needing outside metallic conduit, twine binding with fabric strap or plastics strap etc. in addition then, make heat insulating material be anchored on pipeline outer wall.This traditional pipe insulation method, not only construction technology is numerous and diverse, and because the wind conveying pipe in it is a metal matter, its overwrap is fabric and plastic products.In long-term use, pipe can be subjected to the corrosion of unclean steam in it; Its peripheral wrappage is owing to long term exposure also unavoidable aging coming off in air, so promptly need maintain and replace in use for some time.
The purpose of the present utility model provides a kind of novel, can be used for the pipeline that the hot and cold wind of central air conditioner system is carried, and wishes the conveying that it can not only guarantee cold and hot wind effectively, and it is simple in structure, the corrosion of pipe in both having prevented can prevent the aging of outer tube sleeve again, prolongs the air channel replacement cycle.
The guiding theory of the utility model design is to adopt glass-reinforced plastic material as the air channel body, to improve its corrosion resistance, adopts airtight air as isolation layer simultaneously, removes insulating.
This glass fiber reinforced plastic air channel is made up of outer tube parietal layer (2), inner tubal wall layer (3) and flange (1), it is characterized in that described inner and outer pipe parietal layer is nested with together with one heart, and then be air channel (5) at the center that forms its inner tubal wall layer (3) of airtight gap (4) under the cooperation of the one group of flange in two ends (1) between two tube walls.
According to the glass fiber reinforced plastic air channel of such scheme design, its used glass fiber reinforced plastic is anti-flammability glass fiber reinforced plastic; As adopting during glass fiber reinforced plastic, the inwall of its inner tubal wall layer (3) can apply the fire-retardant coat of one deck (6).
According to the glass fiber reinforced plastic air channel of above schematic design, compare with the air channel with existing central air-conditioning, its advantage is: air channel itself possess in light weight, intensity is high, corrosion-resistant, nonhygroscopic, non-leakage, aging-resistant strong point; And construction and installation are simple, and layout is handsome in appearance.
Accompanying drawing 1 is the structural representation in glass fiber reinforced plastic air channel;
Accompanying drawing 2 is the utility model cross sectional representation.
Further describe the utility model and provide embodiment below in conjunction with accompanying drawing.
Among the figure: 1 is flange, 2 outer tube parietal layers, 3 inner tubal wall layers, 4 seal clearances, 5 air channels, 6 coats.
When actual fabrication,, then inner tubal wall layer (3) is gone here and there in outer tube parietal layer (2) as long as earlier need on model, paste the good outer tube parietal layer of coiling (2), inner tubal wall layer (3) respectively by design, and at two ends affixed upper flange plate (1); Promptly get glass fiber reinforced plastic described in the utility model air channel thus.In the central air-conditioning installing engineering,, promptly form the ventilation stack of random length as long as each joint glass fiber reinforced plastic air channel is penetrated in the flange screw in every adjacent two joint air channels fasteningly with bolt.Because this inside and outside, air channel is formed by the glass reinforced plastic pipe parietal layer, so have good intensity and anti-rotten, weather resistance performance; Glass fiber reinforced plastic itself is the heat transfer non-conductor in addition, the hollow heat insulated layer that the airtight gap (4) that more forms between the inner and outer pipes parietal layer forms, so air channel (5) as the central cold and heat source of transmission, can transmit Cryogenic air expeditiously, high temperature heating installation in cold winter then can be carried again effectively in hot summer.Has the incomparable advantage in present central air-conditioning metal matter air channel.
In the design, cause that air expands when avoiding carrying hot gas to cause the distortion of inner and outer pipes parietal layer, offer small pore outside on the wall layers, play the fine adjustment effect.
Claims (2)
1, a kind of glass fiber reinforced plastic air channel is made up of outer tube parietal layer (2), inner tubal wall layer (3) and flange (1), it is characterized in that described inner and outer pipe parietal layer is nested with together with one heart, and forming airtight gap (4) under the cooperation of the one group of flange in two ends (1) between two tube walls, the center of its inner tubal wall layer (3) then is air channel (5).
2, glass fiber reinforced plastic according to claim 1 air channel is characterized in that described glass fiber reinforced plastic air channel made by fire proofing; As adopting during glass-reinforced plastic material, its inner tubal wall layer (3) inwall can apply the fire-retardant coat of one deck is set.
