Abstract
The utility model relates to an enamel ventilation duct which is an upgraded product of the existing ventilation duct. The utility model is formed by assembling single section ventilation ducts which is formed by that two pipes are butted; the pipes are formed steel plate pieces both surfaces of which are provided with enamel protective layers; the edge of each pipe is provided with turned edge with a connecting hole; sealing gaskets are arranged between the turned edges of the interfaces of the ventilation duct. The ventilation duct has the advantages of light weight, high intensity, corrosion resistance, no air leakage and easy centralization processing and transportation.
Description
The utility model relates to ventilating duct.
In engineering services and various building, use ventilating duct in a large number.Existing ventilating duct is mostly with steel sheet, and galvanized sheet is made single-unit garden pipe or the rectangular tube winding forms, and the ventilating duct with inorganic material sheet material assembly unit winding is also arranged.In installing, using, find that existing ventilating duct respectively has shortcoming, the insufficient strength that has, the perishable life-span is short; The weight that has is big, be difficult for installation, cost height.
The purpose of this utility model be exactly to provide a kind of in light weight, corrosion-resistant, intensity is high, be convenient to the ventilating duct making, transport and install, use.
Form by the single-unit airduct winding that involutes with two tubing for reaching the ventilating duct that goal of the invention designs, tubing is the two-sided shaped steel plate spare that the enamel protective coating is arranged, all there is turning edge of band connecting hole at every tubing edge, between the interface of ventilating duct turns edge sealing mat is arranged.
The utility model ventilating duct can be according to the engineering design requirement, concentrates processing, is pressed into the monolithic tubing of the connecting hole that turns edge earlier with the steel sheet material, counterenamel again, and closed assembly is transported to the construction plant splicing and installs.Have in light weight, intensity is high, corrosion-resistant, do not leak out, easy advantages such as processing, easy transportation and installation, be the regeneration product of existing ventilating duct.
For ease of processing, transportation and increase working strength, the involutory limit of single-unit airduct preferably places on the long limit of ventilating duct cross section.
Embodiment describes the utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model enamel ventilating duct structural representation.
As shown in Figure 1, ventilating duct is by forming with 1 pair of synthetic single-unit airduct winding of two tubing.Tubing 1 is the two-sided shaped steel plate material that the enamel sheath is arranged, and what all there was a band connecting hole 4 at every tubing 1 edge turns edge 3, and the interface of ventilating duct turns edge between 3 lining with sealing mat 5.The involutory limit 6 of single-unit airduct places on the transversal face length of the ventilating duct limit 2.
Claims (2)
1, a kind of ventilating duct, it is characterized in that said ventilating duct is by with two tubing synthetic single-unit airduct winding being formed, tubing is the two-sided shaped steel plate spare that the enamel protective coating is arranged, and all there is turning edge of band connecting hole at every tubing edge, between the interface of ventilating duct turns edge sealing mat is arranged.
2, ventilating duct according to claim 1 is characterized in that the involutory limit of said single-unit airduct places on the long limit of ventilating duct cross section.
