当控制阀专业人士在谈及"控制阀尺寸(Control Valve Sizing)",指的是选用合适的阀门来适用于控制过程。 选择大小适宜的阀是一个重要的过程的一部分,但也还有其他一些同样重要的考虑因素。 控制阀的大小应选择操作范围在60%和80%开度所需大的流量和不低于20%开度所需的小的流速。我们的想法是尽可能多地使用阀门...

Control valve characteristicsControl valve sizingMaterial selection for valvesValve flow coefficientValves are the components in a fluid flow or pressure system that regulate either the flow or the pressure of the fluid. This duty may involve stopping and starting flow, controlling flow rate, diverting...
Basics of Control Valve Sizing The following illustration shows these constrictive points within two different control valve types (shown by arrows): The act of choosing an appropriate control valve for the expected energy dissipation is called valve sizing. ...
Sizing a control valve for a steam application can be a complex matter. This Module attempts to throw light on the subject by using first principles to explain the relationship between flow and pressure drop. It uses a simple nozzle to explain the phenomenon of critical pressure, ...
