摘　　要：对气动调节阀固有流量特性和调节阀口径的选择、气动执行机构空气储罐的配置、气动控制阀手轮机构的设置等3个重要选用要求进行了分析,为氯碱生产中气动控制阀的正确选用提供了有力支持。This paper analyzes three important selection requirements,namely the selection of the inherent flow characteristics and the diameter of the pneumatic control valve,the configuration of the air storage tank of the pneumatic actuator,and the setting of the handwheel mechanism of the pneumatic control valve,providing strong support for the correct selection of pneumatic control valves in chlor-alkali production.

关 键 词：流量特性 流量系数 空气储罐 手轮机构
