First, the characteristics of air volume regulating valve
通风管道 标准化规定的矩形风管尺寸相同。 (L) The connection size of the split-leaf multi-leaf air volume adjustment valve is the same as the rectangular air pipe size stipulated by the national standard for ventilation ducts . 调节阀 。 (2) The blades of the air volume regulating valve are split-type and forward-opening type, and are used as regulating valves in ventilation, air conditioning, and air purification systems . 漏风量 在5%左右，调节性能好。 (3) Through testing, the air-tightness of the air volume adjustment valve is good, and its relative air leakage is about 5%, and the adjustment performance is good.
Structural features of air volume regulating valve
(1) The air volume adjustment valve is unified in four specifications in the blade width. The blade shape is diamond-shaped double blades, and the blades are soft overlapped, so the sealing performance is good.
阀体构架用2毫米 镀锌板 冷轧成型后,以二氧化碳气体保护焊接或由普通 Q235 板加工焊接而成；叶片用1毫米镀锌板冷轧为瓦楞形，两片合成 点焊 插方轴，或2毫米G235钢板冷压成形，单片 冲孔 插方轴或焊圆轴。 (2) Air volume control valve body frame is cold-rolled with 2 mm galvanized sheet , and then welded with carbon dioxide gas shielded welding or processed by ordinary Q235 sheet; blades are cold-rolled with 1 mm galvanized sheet to corrugated shape, two Synthetic spot welding insert square shaft, or 2 mm G235 steel plate cold-pressed forming, single piece punching insert square shaft or welding round shaft.
Application range of air volume regulating valve
It is widely used in industrial, mining, and civil building HVAC systems to precisely regulate the air flow rate. It is one of the key devices to achieve ventilation control in various environments. Its main features are flexible operation, low noise, small leakage, (closed leakage <0.5%), wide operating temperature range, reliable structure, safe and convenient.
