Abstract
The utility model provides a kind of rectangular air duct, it is characterized by comprising galvanized steel plain sheets, glass inner-lining cellucotton layer, flange, weather strip, weldering nail, forked tail filament, there are four faces for the galvanized steel plain sheet, the galvanized steel plain sheet in four faces connects into a rectangular tube, the both ends surrounding of the rectangular tube is horizontally installed with flange, corner brace is installed between the adjacent flange, glass inner-lining cellucotton layer is installed on the inside of the rectangular tube, two end faces of the glass inner-lining cellucotton layer are installed in weather strip, it is linked together between the side and galvanized steel plain sheet of the weather strip by forked tail filament.The utility model glass inner-lining cellucotton layer plays the role of keeping the temperature noise elimination, avoid gas temperature when passing through air hose lost and sonic propagation of making an uproar, reached simultaneously by the way that heat preservation is made in the mode inside air hose and complete processing and fabricating in factory, avoids the secondary heat preservation in construction site.
Description
Technical field
The utility model relates to air shooter technical field more particularly to a kind of rectangular air ducts.
Background technique
Air hose is the pipe-line system for air delivery and distribution.There are composite air duct and two kinds of inorganic air hose.It can be by section
Shape and material classification.Zinc-plated air hose production is to coat sealant at the gaps such as seaming seam, riveted seam, flange flange quadrangle
(such as neutral density glass glue).Surface dirt and greasy dirt should be removed before applying sealant.By cross sectional shape, air hose can be divided into circular duct,
Rectangular air duct, oblate air hose etc. is a variety of, and wherein circular duct resistance is minimum but height dimension is maximum, and production is complicated.So using
Based on rectangular air duct.By material, air hose can be divided into metal bellows, composite air duct, macromolecule air hose.Existing air hose exists
Many disadvantages, such as: connection is not secured enough, and the aesthetic appearance and firm stable of air hose are poor；The poor thermal insulation property of air hose, effect of eliminating the noise
Fruit is insufficient.
Summary of the invention
According to the above technical problem, the utility model provides a kind of rectangular air duct, it is characterised in that including galvanized steel plain sheet, interior
Serve as a contrast glass fibre cotton layer, flange, weather strip, weldering nail, forked tail filament, the galvanized steel plain sheet there are four face, four faces it is zinc-plated
Steel plate connects into a rectangular tube, and the both ends surrounding of the rectangular tube is horizontally installed with flange, pacifies between the adjacent flange
Equipped with corner brace, the flange periphery is equipped with card slot, and the corner brace is equipped with chimb, and the card slot blocks chimb, the folding of corner brace
Crook is equipped with elliptical aperture, is equipped with glass inner-lining cellucotton layer on the inside of the rectangular tube, and the two of the glass inner-lining cellucotton layer
A end face is installed in weather strip, is linked together between the side and galvanized steel plain sheet of the weather strip by forked tail filament.
Weldering nail is installed, the weldering nail welding ensures glass inner-lining on galvanized steel plain sheet on the glass inner-lining cellucotton layer
The fixation of cellucotton layer.
The glass inner-lining cellucotton layer passes through liner adhesive bonding in the inner wall of rectangular tube.
The utility model has the following beneficial effects: the utility model glass inner-lining cellucotton layer plays the role of keeping the temperature noise elimination, keep away
Exempt from gas temperature when passing through air hose to scatter and disappear and sonic propagation of making an uproar, while be reached by the way that heat preservation is made in the mode inside air hose
Processing and fabricating is completed in factory, avoids the secondary heat preservation in construction site, is factory prefabricating power-assisted, guarantees also to avoid while quality
Engineering site generates secondary building, shortens construction period；Glass inner-lining cellucotton layer is by liner adhesive bonding in square
The inner wall of shape pipe, by that will weld the fixation of nail welding true glass inner-lining cellucotton layer on the steel plate, dual connection type can be protected
Card glass inner-lining cellucotton layer is firmly fixed together with galvanized steel plain sheet；Pass through swallow between the side and galvanized steel plain sheet of weather strip
Tailfiber connects together, and improves the fastness of air hose entirety.
Detailed description of the invention
Fig. 1 is the utility model section view.
Fig. 2 is the utility model schematic top plan view.
Fig. 3 is the utility model corner brace schematic diagram.
Such as figure, galvanized steel plain sheet -1, rectangular tube -2, flange -3, corner brace -4, card slot -5, edge -6, glass inner-lining cellucotton
Layer -7, weather strip -8, forked tail filament -9, weldering nail -10, elliptical aperture -11, liner adhesive -12.
Specific embodiment
Root according to the figure, is further described the utility model:
Embodiment 1
A kind of rectangular air duct, including galvanized steel plain sheet, glass inner-lining cellucotton layer, flange, weather strip, weldering nail, forked tail filament, plating
There are four face, the galvanized steel plain sheets in four faces to connect into a rectangular tube 2 for zinc steel plate 1, and the both ends surrounding of rectangular tube is horizontally installed with
Flange 3 is equipped with corner brace 4 between adjacent flange, and the bending part of corner brace is equipped with elliptical aperture 11, and flange periphery is equipped with card slot 5, angle
Code is equipped with chimb 6, and card slot blocks chimb, is equipped with glass inner-lining cellucotton layer 7, glass inner-lining cellucotton on the inside of rectangular tube
Two end faces of layer are installed in weather strip 8, are connected to one by forked tail filament 9 between the side and galvanized steel plain sheet of weather strip
It rises.
Weldering nail is installed, weldering nail 10, which is welded on galvanized steel plain sheet, ensures glass inner-lining cellucotton on glass inner-lining cellucotton layer
The fixation of layer.
Glass inner-lining cellucotton layer is bonded in the inner wall of rectangular tube by liner adhesive 12.
Embodiment 2
When assembling air hose, the flange 3 between adjacent air hose is docked, is connected flange 3 by bolt, it will be adjacent
Air hose connects；During conveying air, 7 pairs of air of glass inner-lining cellucotton layer have certain heat preservation and noise elimination effect, prevent
Only the temperature of gas is scattered and disappeared.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvement can also be made, these improvement are also answered
It is considered as the protection scope of the utility model.
