pp manual valve

pp valve, manual valve, manufactured by the welcome. First, the characteristics of air volume control valve (l) off more Yefeng same amount adjusting valve over size with the national standardization ventilation ducts specified rectangular duct size. (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. Second, the air flow control valve structure 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. (2) the air flow 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. (3) The valve sub-manual, electric, according to the materials point: the same iron, galvanized sheet, aluminum plate, stainless steel four, body structure and size specifications. Third, the air flow control valve Scope Widely used in mining, civil construction and HVAC systems, air flow is accurately adjusted, it is one of the key devices to achieve a variety of environments under control ventilation mode. Its main feature is flexible operation, low noise, small amount of leakage, (hermetic leakage <0.5%) Operating temperature region wide, reliable structure, safe and convenient.
