摘　　要：提升阀系一种线性直线运动的流体控制阀。其动密封系统往往要求良好的密封性和低的摩擦力。针对某提升阀动密封系统对摩擦力的要求,基于已有密封设计,使用了有限元分析结合实验的方法,根据响应曲面优化设计理论,对现有密封系统设计进行了尺寸参数优化。通过蒙特卡罗模拟分析和实验的方法,验证了优化后的密封系统可以满足密封系统既定摩擦力和泄漏要求。Lifting valve is a kind of fluid control valve with linear movement. The dynamic sealing system of the lifting valve normally requires a proper sealing performance and low friction. The paper regards the friction requirement of a kind of lifting valve sealing system based on the existing sealing system design,applies the FEM and verification approaches,optimizes the dimensions of existing sealing system by using response surface optimizing method. It is validated that the optimized sealing system could meet the friction and leakage requirement regarding the results of Monte Carlo simulation and tests.
