Embodiment Construction

[0081] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0082] Such as Figure 1~22 As shown, the present invention provides a specific embodiment of a color-steel composite air duct. The color-steel composite air duct is composed of several air duct sections connected by a clip-type quick-installation connection device D, and the air duct section includes a straight pipe section A , variable-diameter pipe section B and elbow pipe section C, the clip-type quick-fit connection device D is composed of two aluminum alloy heat-insulating bridge breaker flanges D1 integrally connected by a C-shaped clip D2, wherein: two aluminum alloy spacers The connection between the flanges of the thermal break bridge is coated with a sealing strip; two adjacent straight pipe sections A can be fastened through the snap-type quick-fit connection device D, and two adjacent variable-diameter pipe sections ...

Abstract

The invention relates to the technical field of composite air ducts, in particular to a color steel plate composite air duct. The color steel plate composite air duct is formed by connecting a plurality of air duct sections through clamp type quick mounting connecting devices (D), each air duct section comprises a straight tube section (A), a reducer tube section (B) and a swan neck section (C), each clamp type quick mounting connecting device (D) is formed by integrally connecting two aluminum alloy thermal-insulation bridge cutoff flanges (D1) through a C-shaped clamping strip (D2); and a sealing rubber strip coats a connection position between each two aluminum alloy thermal-insulation bridge cutoff flanges (D1). Because the technical scheme is adopted, different types of tube sections are connected to one another in a matched manner in the air duct sections, and the different types of the tube sections have good airtightness and fastening performance; some barriers (such as columns, corners and equipment pipes) can be avoided in a whole composite air duct mounting process; and smoothness and stability of delivered air volume in the composite air duct are guaranteed.

Description

technical field [0001] The invention relates to the technical field of composite air ducts, in particular to a color steel plate composite air duct. Background technique [0002] The color steel composite air duct is an updated product of the traditional glass fiber air duct, and it is also a new generation evolution product of the galvanized iron air duct. Its advantages are good air tightness, high strength, strong acid and alkali resistance, and anti-corrosion performance. Good noise reduction effect and good heat preservation effect, no need for secondary heat preservation. At present, the production methods of color steel composite air ducts are diversified, but there are generally problems such as insufficient strength, high air leakage rate, and escape of sandwich insulation materials. At the same time, the production process is complicated, and it is difficult to fully realize mechanized production. Contents of the invention [0003] In order to solve the above pr...
