Air volume control valve, also known as regulating dampers, is an indispensable central air conditioning end fitting in the ventilation, air conditioning and air purification projects of industrial plants and civil buildings, generally used in air conditioning, ventilation system piping, used to regulate the air volume of the pipeline, but also used for the mixing of the new air and the return air regulation.
cooling olis
(1) The receiver size of the folio multi-leaf air flow regulating valve is the same as the size of the rectangular duct as stipulated in the national standardization of ventilation ducts.
(2) The blades of the air flow regulating valve are of foliate and smooth-open type, which are used as regulating valves in ventilation, air conditioning and air purification systems.
(3) The airtightness of the airflow regulating valve is determined through tests, and its relative air leakage is about 5%, with good regulating performance.
What are the structural characteristics?
(1) The air volume control valve in the blade width of the whole unified for the four specifications, blade shape for the diamond-shaped double blade, the blade between the use of soft lap joints, so the airtight performance is good.
(2) air volume control valve valve body frame with 2 mm galvanized plate cold rolled(VCD FRAME ROLL FORMING MACHINE), carbon dioxide gas shielded welded or welded by the ordinary Q235 plate processing and become; blade with 1 mm galvanized plate cold rolled for corrugated, two pieces of synthetic spot welded inserted square axle, or 2 mm G235 steel plate cold pressed into shape, a single piece of punched inserted square axle or welded round axle.
(3) The regulating valve is divided into manual, electric, according to the material used: iron plate, galvanized plate, aluminum alloy plate, stainless steel plate four, the valve structure and specifications of the same size
Scope of application
Widely used in industrial and mining, civil building HVAC system, the air flow for precise adjustment, is to realize a variety of environments to control the ventilation mode of one of the key equipment. Its main features are flexible operation, low noise, small leakage, (closed type leakage < 0.5%) wide working temperature region, reliable structure, safety and convenience.
