The valve flow coefficient, often denoted as Cv, measures the fluid flow rate through a control valve. 阀流量系数,通常表示为Cv,测量通过控制阀的流体流速。 It is a crucial factor in valve sizing as it helps determine the appropriate valve size for optimal performance. 它是阀门尺寸的一个关键因素...
调节阀适用于空气、水、蒸汽、各种腐蚀性介质、泥浆、油品等介质。英文名:control valve,位号通常FV开头。调节阀常用分类:气动调节阀,电动调节阀,液动调节阀,自力式调节阀。差不多,计算出来的CV值在根据阀门的固定CV值去比较,然后考核其开度,每个厂家的阀门CV值并不一定相同。 调节阀口径的选择和确定主要依据阀的...
