多葉調節閥多安裝在主風道和分支風道上，電動多葉調節閥，山東通風管道加工是在調節閥驅動主軸上安裝一電動執行器，接通電源，調整其執行器指針位置，使其可順時針和反時針方向旋轉，并帶動主軸上連接的閥葉開啟和關閉。

　　Multi multi leaf valve installed in the main duct and branch duct, multi leaf valve, Shandong ventilation pipe processing in regulating valve is arranged on a main shaft of a driving electric actuator, switch on the power, adjust the actuator pointer position, the clockwise and counter clockwise rotation, and drives the main shaft on the valve leaf with the opening and closing.

　　當按下執行器上的手動卸載按鈕，手動調節閥葉也可由全關全開的位置。帶電動執行器的多葉調節閥多安裝在精密機房空調配套的新風機進風口處，電源線路與機組內風機的電機連鎖，即當機組風機停運后其新風管道閥也同時處于關閉狀態。

　　When you press the button to manually uninstall the actuator, the manual control valve can be fully closed to fully open leaf position. With electric actuator of the multi leaf valve installed in the fresh air inlet at room air conditioning machine precision matching motor, fan power line and chain units, namely when the unit fan after the shutdown of the air pipe valve is also closed.

　　在冬季使用時會避免因新風機停機后冷空氣進入機組凍結換熱器內水，同時還可因建筑物內發生火災后，消防自控裝置自動切斷風機電源后，防止室外空氣進人風道內而加大火勢。

　　In the winter when used to avoid air machine after cold air into the heat exchanger unit of frozen water, but also because of the fire in the building, automatically cut off the fan power supply for fire control device, to prevent outside air into the air duct and increase the fire.

　　多葉調節閥規格很多，一般安裝在風道上，與風道斷面尺寸相同。在使用手動多葉調節閥，需調整風量時，將其葉片調整開啟一定角度后，應用鎖緊螺母將其固定。電動執行器宜選用體積小、扭矩大、控制精度高、可靠性高、安裝方便的產品。

　　The multi leaf regulating valve has many specifications, generally installed on the air duct, and the same size as the cross section of the air duct. When the manual multi leaf regulating valve is used, when the air volume is adjusted, the blade is adjusted to a certain angle, and the locking nut is used to fix the air quantity. Electric actuator should choose small size, high torque, high control accuracy, high reliability, easy installation of the product.

　　對開式密閉多葉調節閥可分手動和電動兩種類型，因采用對開葉片，氣流較均勻，并可手動連桿帶動葉片轉動，調整通過氣流的流量，同時還可完全關閉使氣流無法通過。因其葉片邊緣嵌有密封膠條，在關閉時可保證其嚴密性，具有阻力小，漏風量小等優點。

　　The open closed multi leaf valve can be manual and electric two types, due to the use of the blade, flow is uniform, and can be manually adjusted through the connecting rod drives the blade to rotate, the flow of air flow, but also can make the air can not completely shut down. Because the blade edge is embedded with a sealing strip, the tightness can be ensured when the seal is closed, and the utility model has the advantages of small resistance and small air leakage.

　　蝶閥構造簡單、操作方便，起著開啟關閉或調節風量的作用，但開啟阻力較多葉調節閥大，一般多安裝在進入精密機房空調的支風道上。根據結構形式蝶閥有拉鏈式和手柄式兩種類型。

　　Butterfly valve structure is simple, easy to operate, play the role of opening, closing or regulating the air volume, but more resistance to open, large leaf valve, usually installed in the air inlet into the precision room air duct. According to the structure of butterfly valve, there are two types of zipper and handle type.
