AI Technical Summary
The existing installation methods for hospital ventilation duct networks involve a large amount of construction work and are not convenient for disassembling and assembling individual ventilation duct components. They are also difficult to maintain and replace, especially in environments with people around the clock.
A noise-reducing docking mechanism with flat ends is adopted at the interface of ventilation ducts and air volume regulating valves. Threaded fasteners are used to lock the connection between adjacent ducts and valves, and composite sound insulation pads are pasted on the outer wall. Rubber rings are used to insulate and reduce noise at the splicing seams.
It enables convenient disassembly and assembly of ventilation ducts and air volume regulating valves, reducing the amount of construction work, and effectively reduces noise transmission into the room through the design of composite sound insulation pads and rubber rings.
