调节阀流量系数与可调比关系的研究 总被引:4,自引:0,他引:4
The relationship between
flow coefficient and turndown ratio is discussed based on the requirements of practical
applications. Thus it
is stated that the turndown ratio might be considered as the characteristic parameter of
the flow characteristic curve. On this basis the difference between the National Standard and International
Standard in regulations of the deviation of flow coefficient is stated. Through relevant calculations, the demerits existing in
National Standard and product design are revealed. 相似文献
