Describe The Usage Points Of Air Volume Control Valves And Electric Fire Dampers

The air volume control valve has four unified specifications for blade width, with diamond shaped double blades and soft overlapping between the blades, resulting in good sealing performance. The structure of the air volume regulating valve body is formed by cold-rolled 2mm galvanized sheet, and then welded with carbon dioxide gas protection or processed and welded from ordinary Q235 plate; The blade is cold-rolled into a corrugated shape using 1mm galvanized sheet, with two composite spot welded square shafts or 2mm G235 steel plate cold pressed into shape, and a single punched square shaft or welded circular shaft.
Electric fire dampers are made of insulated air duct panels and can be installed and manufactured on the construction site. Simply use cutting tools, cut and glue them into shape, combine them with flange inserts, and seal them with sealant. The steel and accessories used for hoisting are simple and lightweight, resulting in less labor and faster progress, which is 2-3 times faster than traditional installation. This saves labor costs and reduces construction risks. During the use of electric fire dampers, if there is any damage, they can be easily cut, bonded, and repaired, making maintenance quite convenient.
