The size of the split multi-leaf air volume regulating valve is the same as the rectangular air duct size specified in the national ventilation duct standardization.
The blades of the air volume regulating valve are split-type and sequentially-opening types, and are used as regulating valves in ventilation, air conditioning, and air purification systems.
It has been determined through experiments that the air volume regulating valve has good air tightness, its relative air leakage is about %, and its regulating performance is good.
2. Structural Characteristics of the Air Volume Control Valve
The air volume control valve has four specifications in blade width. The blade shape is a rhombus-shaped double blade. The blades adopt soft overlap, so the sealing performance is good.
The air volume control valve body structure is cold-rolled with 1/2 mm galvanized sheets, and then welded with carbon dioxide gas protection or processed and welded from ordinary Q plates. The blades are cold-rolled with 1/2 mm galvanized sheets into a corrugated shape, and the two pieces are combined. The square shaft is welded and inserted, or the millimeter steel plate is cold pressed, and the square shaft is punched and inserted into the single piece or the round shaft is welded.
The control valve is divided into manual and electric, and is divided into four types according to the materials used: carbon steel plate, galvanized plate, aluminum alloy plate, and stainless steel plate. The valve body structure and specifications are the same.
3. Scope of application of air volume regulating valve
It is widely used in HVAC systems of industrial, mining and civil buildings to regulate air flow. It is one of the key devices to control ventilation modes in various environments. Its main features are flexible operation, low noise, small leakage, (closed leakage &%) wide operating temperature range, reliable structure, safety and convenience.
