防排烟设备选用及控制原理

摘要

介绍了防排烟设备的种类、原理、适用场合,重点介绍了防火阀、排烟阀、排烟口、多叶排烟口等设备的功能异同.分析了防排烟阀门与消防控制模块、排烟风机控制箱之间的信号传递关系.根据典型排烟系统的特点,设计了控制原理图.%Presents the types, principle and applicability of smoke control equipment, and emphasizes the similarity and dissimilarity in the function of fire dampers, smoke extraction valves, exhaust smoke outlets and multi-blade smoke exhaust outlets. Analyses the signal transfer relationship among smoke control valves, the fire control console and the ventilator control box. Prepares the control principle drawing based on the characteristics of typical smoke exhaust systems.
