Shandong ventilation duct processing air flow control valve can be used in subway ventilation, air conditioning system fire prevention and smoke exhaust, valve with fire automatic alarm equipment and gas fire extinguishing system linkage control function.

　　每臺全自動風量調節閥有兩個獨立電動控制信號，分別由EMCS、氣消系統進行監控，控制信號均為DC24V±10%信號。風量調節閥在安裝時一定要做好以上幾個注意事項，只有這樣在火災發生時才能發揮它的特性，保護人身和財產。

　　Each automatic air volume control valve has two independent electric control signals, which are monitored by EMCS and gas elimination system respectively, and the control signals are DC24V + 10% signals. In the installation of air flow control valve, we must do a good job of the above considerations, only in this way, when the fire can take place in its characteristics, protect personal and property safety.

　　1.排煙防火閥選用主要控制參數為規格等。

　　1. smoke exhaust fire valve, the main control parameters for specifications.

　　2.排煙防火閥葉片應為鋼板，厚度為2~6mm，閥體為不燃材料制作，轉動部件應采用耐腐蝕的金屬材料，并轉動靈活。閥門的外殼厚度不得小于2mm。易融部件應符合消防部門的認可標準。

　　2., smoke exhaust valve blade should be steel plate, the thickness of 2~6mm, the valve is non combustible material, the rotating components should be corrosion-resistant metal materials, and flexible rotation. The shell thickness of the valve shall not be less than 2mm. Easy to melt components shall comply with fire department approval standards.

　　3.選用排煙防火閥時應注意閥門的功能，如常開還是常閉、自動關閉開啟、手動關閉開啟、手動復位、訊號輸出、遠距離控制等要求。

　　3. selection of smoke fire valve should pay attention to the function of the valve, normally open or normally closed, automatic shutdown, open, manual closed, open, manual reset, signal output, remote control requirements.

　　4.排煙防火閥適用于通風、空調或排煙系統的管道上.

　　4. smoke dampers are suitable for ventilation, air conditioning, or smoke extraction systems

　　5.排煙防火閥適用于通風空調系統，除公共建筑的廚房排油煙系統用防火閥，動作溫度為150℃外，一般通風空調系統用排煙防火閥動作溫度為70℃。

　　5. smoke fire dampers for ventilation and air conditioning system, in addition to public buildings kitchen smoke exhaust system with fire dampers, action temperature of 150 degrees outside, general ventilation and air conditioning system with smoke exhaust fire valve action temperature of 70 degrees.

　　6.排煙防火閥若與風機聯動的應選用帶雙微動開關裝置。

　　6. if the smoke damper and the fan linkage should be selected with dual micro switch device.
