Design of a Gas Flow Measurement Device for a Nuclear Military Production Line

文章设计了一套氟气流量测量装置,该装置不仅提高了氟气流量测量精度而且提高了氟气利用率。首先分析了热式质量流量计的工作原理,根据工作原理和工艺需求,制定技术指标,研制氟气流量计,通过测试各项指标满足技术要求;然后通过黄金分割法,编写C语言程序,计算最优流量系数,并通过试验数据可知该气动调节阀满足工艺需求。该装置应用于生产后,不仅提高了氟气流量的测量精度,而且提高了产品质量,减少了核材料浪费。

In this paper,a set of fluorine gas flow measuring device is designed according to the process demand of a nuclear military production line.The device not only improves the measurement accuracy for the gas flow rate,but also improves the utilization rate of fluorine gas.This paper first analyzes the working principle of thermal mass flowmeter,,then formulates technical indicators and develop fluorine gas flowmeter according to the working principle and process requirements,and shows that all indicators meet technical requirements through testing;secondly,the optimal flow coefficient is calculated through the golden section method and C language programming,and the test data show that the pneumatic control valve meets the process requirements;finally,this device is successfully applied to the production line.Practice proves that not only the measurement accuracy of the fluorine gas flow is improved,but also the quality of the nuclear military production line product is improved,the waste of nuclear materials is reduced.
