摘　　要：阀芯液动力补偿是高速开关阀设计中的一个关键环节。在分析阀口液动力补偿策略的基础上,提出了缝隙滑阀结构,这种结构能有效减小阀芯的稳态液动力。通过试验,测试了缝隙滑阀基本参数——阀口压差、阀口开度和缝隙宽度分别与稳态液动力和阀口流量系数的关系。结果表明,采用缝隙滑阀结构能有效地减小阀芯的稳态液动力,为高速开关阀优化设计提供了试验依据。Hydraulic power compensation for valve spool is a key step in the design of high speed on/off valves. On the basis of analyzing hydraulic power compensation strategy for valve port, a gapped slide valve structure is suggested. With the structure, static hydraulic power of a valve spool can be effectively decreased. Through test, relationship of basic parameters of gapped slide valve, pressure drop at valve port, valve port opening and gap width vs static hydraulic power and valve port flow coefficient are measured respectively. The results show that, adopting gapped slide spool structure, static hydraulic power of the spool can be effectively reduced, which provides an experimental basis for optimal design of high speed on/off valve.
