引言在工业生产中,标准节流装置应用十分广泛,但是只有在符合标准要求的技术条件下,才能使用标准节流装置正确地测量流量。而在工程实际应用中,当雷诺数远小于标准推荐使用的最小雷诺数、标准节流装置的流量系数变化过大而不能使用时,需要采用一些非标准形式
Introduction Standard throttling devices are widely used in industrial production, but standard throttling devices can only be used to properly measure the flow rate under the technical conditions that meet the requirements of the standard. In engineering practice, when the Reynolds number is far less than the standard recommended minimum Reynolds number, the standard throttle device flow coefficient changes too large to be used, you need to use some non-standard forms
