摘要
基于传统插装式比例节流阀圆形通孔的主阀套结构,提出一种腰形通孔的主阀套新结构,利用CFD技术对以上两种通孔形式的阀的流量特性、主阀芯受力情况进行对比分析,并基于相似理论进行了可视化实验研究。研究结果表明:主阀套采用腰形通孔结构相对于传统的圆形通孔结构,不仅增加了阀的通流能力,还改善了主阀芯所受的径向不平衡力。研究结果为插装阀的结构优化设计及实验研究提供了理论依据。
Based on traditional round through-hole structure of main valve sleeve of cartridge pro- portional throttle, an optimized kidney-shaped through-hole structure was proposed herein. The computational fluid dynamics （CFD） technology was used to analyze flow characteristics of these through-hole forms mentioned above and the force of main valve spool. Then, visualization experi- mental study which was based on the similarity theory was completed. The research results show that compared to traditional round through-hole structure, kidney-shaped through-hole structure can increase ftow capacity and improve radial unbalanced force of the main spool. This research can provide theory basis for structure optimization design of cartridge Drooortional thrnttle.
