摘要
对调节阀固有阻力特性进行了分析 ,推导出调节阀固有阻力关系式 ,提出了衡量调节阀阻力的特征阻力概念。对调节阀安装特性进行了分析 ,得到调节阀流量调节方程式。依调节阀的结构特点将调节阀的开度划分为有效行程区、无效行程区和强调节区三个区域。提出了界点的定义 ,得到在安装状态下 。
Adjusting equation of the control valves and inherent flow relationship was established. In term of the regulator structure features, the openings of regulator can be classified into effective movement region, inefficient movement region, and strong adjusting region. It was showed that the critical point of regulator moved downward under the installation condition.
