Where air flow control valve, the lowest price? To find Hao 琼风 flow valve Tel: 18653444408 Manager Wu air volume control valve 1 air flow control valve characteristic structural features of the scope of the second structure principle 3 Technical parameters 1 air volume control valve in the air flow control valve is an industrial plant civil construction of ventilation, air conditioning and air decontamination indispensable central air-conditioning end accessories, generally used in air conditioning, ventilation duct system, used to adjust the air flow manifold can also be used for fresh air is mixed with return air regulation. First, the characteristics of air volume control valve (l) off more Yefeng flow control valve to take over the same rectangular duct size, and the size and structure of the national standardization of ventilation ducts 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. 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. (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. 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. 2 electric air volume control structure principle applies to supply or exhaust air flow range of about 5 Pa pressure range 20-1000 high precision air volume control, make sure the duct is arranged to meet the best flow characteristics before the factory is set up wind or programming , each device in the calibration bench airflow performance test. Identifies relevant parameters such as the need to re-measure or set wind value horizontally or vertically installed in the field on each piece of equipment attached to the test label
