摘　　要：采用二级驱动、非对称的优化设计方法,以三通球阀作为先导级、三通滑阀作为主级,先导级与主级间通过控制活塞进行耦合以降低主级对先导级控制流量的需求,通过消除干扰因素诸如液动力等对主级阀快速运动的影响和优化设计,实现高速开关阀的快速动作。研究结果表明,通过液动力补偿,采用二级驱动的非对称设计方法是提高大流量高速开关阀动态响应的有效途径。This paper uses the two-stage driving and asymmetric optimization design method,takes the three-way ball valve as the pilot stage and the three-way slide valve as the main stage,the coupling between pilot stage and main state was carried out by a control piston to minimize the demand on the pilot stage control flow by the main stage.Through eliminating the influence on the rapid movement of the main stage valve by the interference factor such as hydrodynamic force and etc.,the rapid action of the high speed onoff valve was allowed.Research result indicates that it is the effective way to improve the dynamic response of the large flowand high speed on-off valve by compensating the hydrodynamic force and using the two-stage driving asymmetric design method.
