如何确定调节阀的CV值。？ 控制阀cv的计算一般参照ansi/isa 75.01国际标准，生产厂家也是跟据这个标准，再测出其阀产品的参数，对计算公式加以修正，可按照设计单位给出的工艺要求，选型计算出合适的产品。以下就是设计控制阀相关的国际标准。 ansi/isa 75.01 flow equations for sizing control valves ansi/isa 75.03 face-to-face dimensions for integral flanged globe-style control valve bodies (ansi classes 125, 150, 250, 300 and 600) ansi/isa 75.04 face-to-face dimensions for flangeless control valves (ansi classes 150, 300 and 600) ansi/isa 75.05.01 control valve terminology ansi/isa 75.08 installed face-to-face dimensions for flanged clamp or pinch valves ansi/isa 75.11 inherent flow characteristic and rangeability of control valves ansi/isa 75.16 face-to-face dimensions for flanged globe-style control valve bodies (ansi classes 900, 1500 and 2500) ansi/isa 75.19 hydrostatic testing of control valves ansi/isa 75.22 face-to-centerline dimensions for flanged globe-style angle control valve bodies (ansi classes 150, 300 and 600) ansi/isa rp75.23 considerations for evaluating control valve cavitation ansi/isa tr75.25.02 control valve response measurement from step inputs ansi b16.104 leakage class查看更多
