Cavitation occurring in a sleeve regulating valve not only increases the energy waste of the whole piping system but also causes severe and costly damage to the valve body and the piping system. In this paper, in order to reduce the cavitation inside the sleeve regulating valve, the effects of different valve core shapes, including flat bottom, ellipsoid, circular truncated cone, and cylinder, on cavitation are investigated by using a cavitation model. The pressure, velocity, and vapor volume fraction distribution in the regulating valve are obtained and compared for different valve core shapes and valve core displacements. The total vapor volumes are also predicted and compared. The results show that vapor primarily appears in the gap between the sleeve and the valve core surface. The cavitation intensities for the ellipsoid and cylinder valve cores are greater than those for the other two valve cores. With the increase of the valve core displacement, the total vapor volumes for all four valve core shapes first increase and then decrease. This work is of significance for the optimization and design of sleeve regulating valves.

Focusing on the cavitation in the sleeve regulating valve, CFD simulation is carried out with different valve core shapes. The manuscript is well done and organized.


目的:套筒式调节阀内空化的发生不仅会增加整个管路系统的能量损耗,而且会造成阀体及管路的失效破坏. 本文旨在探讨四种不同形状的阀芯对套筒式调节阀内不同阀芯位移工况下的空化流动及空化强度的影响,为套筒式调节阀的优化设计及空化控制提出建议.
创新点:1. 根据四种不同形状的阀芯,研究套筒式调节阀内阀芯形状对流动及空化特性的影响; 2. 建立数值模型,对套筒式调节阀在不同阀芯形状和不同阀芯位移条件下进行流动及空化分析.
方法:1. 建立带有不同形状阀芯的套筒式调节阀数值计算模型,并比较分析阀芯形状对阀内速度、压力及空化情况的影响(图4,8和11); 2. 建立不同阀芯位移条件下的阀门数值模型,比较分析阀芯位移对阀内速度、压力及空化情况的影响(图6和10); 3. 建立不同形状阀芯及不同阀芯位移下的阀门模型,分析阀芯形状和位移对阀内流动及空化特性的综合影响(图7和13).
结论:1. 在四种不同形状阀芯的条件下,高速流动区域和空化发生区主要位于套筒与阀芯之间的间隙; 2. 在直筒形和椭球形阀芯条件下的阀内空化强度明显强于平底形和圆台形阀芯条件下的空化强度,因此平底形和圆台形阀芯在空化控制方面具有更好的效果; 3. 在四种不同形状阀芯的条件下,随着阀芯位移的增加,阀内由空化产生的蒸汽总体积先增加后减少.
