控制阀的流量系数是一个重要的水力参数，用于选择和设计封闭管道系统的控制装置。该参数用于确定系统的流量、阀门定位和能量损失。该系数还用于分析流动系统的其他现象，例如空化和瞬态。了解流量系数的定义、如何使用以及如何确定控制阀非常重要。目前有两套测试标准来确定阀门的流量系数。这些标准对于如何确定系数的定义有所不同，并且可能会导致阀门产生两组不同的流量系数数据。混乱导致确定使用哪组标准来生成阀门系数信息，以及使用相同的系数定义设计系统的重要性。
The flow coefficient for a control valve is an important hydraulic parameter that is used to select and design the controls for a closed conduit system. The parameter is used to determine flow capacities, valve positioning, and energy losses of the system. The coefficient is also used for the analysis of the flow system for other phenomena such as cavitation and transients. It is important to understand the definition of the flow coefficient, how it is used, and how it is determined for a control valve. At present there are two sets of testing standards to determine the flow coefficient for a valve. The standards are different in the definition of how the coefficient is determined and can result in two different sets of flow coefficient data for a valve. Confusion has resulted in identifying which set of standards was used to generate the valve coefficient information, and the importance of designing a system using the same definition of the coefficient.
