控制阀选型计算中的允许压差

The Allowable Differential Pressure in Calculation of Model Selection for Control Valves

阐述了控制阀选型的主要内容 ,指出了在控制阀选型计算时不进行不平衡力校核可能会造成控制阀泄漏的问题 。

The major contents of model selection of control valve are described. The author states that leakage problem of control valve would be caused if unbalance force verification was not implemented in calculation of model selection. The cautions in selecting allowable differential pressure in unbalance force verification are presented.
