摘要:

以单座套筒调节阀为研究对象,进行了原结构与优化后套筒调节阀流场数值模拟计算,并采用最小二乘法拟合得到了套筒调节阀优化前后在不同开度下的流量特性曲线。研究结果表明:套筒调节阀原结构的流量特性曲线在不同开度的斜率偏差超过标准要求,不符合等百分比流量特性;优化后套筒调节阀的流量特性曲线满足等百分比流量特性要求;CFD数值模拟计算方法可作为套筒调节阀研发设计的重要方法。

Abstract:

Taking the single-seat sleeve control valve as the research object, the numerical simulation calculation of the flow field of sleeve control valve before and after structural optimization was carried out, and the flow characteristic curve of the sleeve control valve before and after optimization at different openings was obtained by using the least squares fitting method. The research results show that the slope deviation of the flow characteristic curve of the sleeve control valve before optimization at different openings exceeds the standard and does not meet the equal percentage flow characteristic, the flow characteristic curve of the optimized sleeve control valve meets the equal percentage flow characteristic requirement, and CFD numerical simulation calculation method can be used as an important method for the development and design of sleeve control valves.
