Air flow control valve Products: air flow control valve - Facing more Yefeng flow valve selected large, our company specialized in producing various air flow control valve, good quality and low price, users love! FT air flow control valve is the company developed and produced a new type of air flow control valve, which combines the advantages of foreign and domestic damper the damper. Has a simple structure and reasonable, leaking a small amount of friction torch small, flexible operation, the blade rigid, corrosion-resistant, variety and so on. Its performance and the parameter index has exceeded a predetermined JB / T7228-94 standards. It can be widely used in the supply and civilian air-conditioning and ventilation systems in order to achieve precise control of air flow purposes. Off more Yefeng flow valve, commonly used in air conditioning, ventilation pipes, used to adjust the air flow just as well as for fresh air is mixed with return air regulation. The valve is divided into two kinds of manual and electric, by sealing points, it can be divided into two kinds and general tightness. Electric automatic control and automatic control systems to regulate air flow supporting. Air volume control characteristics of the valve (l) Yefeng flow valve off more takeover same rectangular duct size and structure size and ventilation ducts standardized national regulations. (2) the air flow control valve leaves off and cis-open in ventilation, air conditioning, air purification system as a regulator. (3) The test determined air flow control valve tightness good, the relative amount of air leakage around 5% regulation performance. Air flow control valve structural features (l) of the air flow control valve in the unity of the whole blade width four sizes, leaf-shaped diamond-shaped double blade, the blade between the soft lap, so good airtight performance. (3) air volume control valve body frame After 2 mm galvanized sheet cold roll forming, with carbon dioxide gas welding or soldering by the general Q235 plate processing; blades 1 mm corrugated galvanized sheet cold rolling, two Synthesis interpolating axis spot welding, or 2 mm G235 steel cold forming, punching chip interpolating axes or welding round shaft. (4) The valve sub-manual, electric, according to the materials Score: iron, galvanized sheet, aluminum plate, stainless steel four, the same body structure and size specifications.
