专注通风管道加工·排烟罩

　　多叶调节阀多安装在主风道和分支风道上，电动多叶调节阀，山东通风管道加工是在调节阀驱动主轴上安装一电动执行器，接通电源，调整其执行器指针位置，使其可顺时针和反时针方向旋转，并带动主轴上连接的阀叶开启和关闭。

　　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.

　　当按下执行器上的手动卸载按钮，手动调节阀叶也可由全关全开的位置。带电动执行器的多叶调节阀多安装在精密机房空调配套的新风机进风口处，电源线路与机组内风机的电机连锁，即当机组风机停运后其新风管道阀也同时处于关闭状态。

　　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.

　　在冬季使用时会避免因新风机停机后冷空气进入机组冻结换热器内水，同时还可因建筑物内发生火灾后，消防自控装置自动切断风机电源后，防止室外空气进人风道内而加大火势。

　　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.

　　多叶调节阀规格很多，一般安装在风道上，与风道断面尺寸相同。在使用手动多叶调节阀，需调整风量时，将其叶片调整开启一定角度后，应用锁紧螺母将其固定。电动执行器宜选用体积小、扭矩大、控制精度高、可靠性高、安装方便的产品。

　　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.

　　对开式密闭多叶调节阀可分手动和电动两种类型，因采用对开叶片，气流较均匀，并可手动连杆带动叶片转动，调整通过气流的流量，同时还可完全关闭使气流无法通过。因其叶片边缘嵌有密封胶条，在关闭时可保证其严密性，具有阻力小，漏风量小等优点。

　　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.

　　蝶阀构造简单、操作方便，起着开启关闭或调节风量的作用，但开启阻力较多叶调节阀大，一般多安装在进入精密机房空调的支风道上。根据结构形式蝶阀有拉链式和手柄式两种类型。

　　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.
