| 摘 要： | 根据U型换向球阀阀腔内液流的流动情况,对其阀腔进行了合理的简化,提出了计算U型换向球阀阀芯轴向瞬态液动力的简化模型,在此基础上推倒出了U型球阀稳定性方程式.利用Routh-Hurwitz稳定性判据,推导出U型换向球阀稳定性条件的关系式,并对其进行了讨论.得出在忽略粘性阻力,弹簧刚度一定的情况下,提高球阀的流量增益,减小压力系数,可增强球阀稳定性的结论,对球阀设计有指导意义.

| Abstract: | Analysis and calculation are done to determine instantaneous axial hydraulic dynamics for U type directional control ball valve on the basis of a simplified model. The stability equations and criterions of U type ball valve are derived. The significant conclusions are obtained after the stability relation is discussed. |
