众所周知,流体流过滑阀时对阀芯所产生的液动力对滑阀的工作影响很大,对它的研究历来是液压流体力学的重要课题。近年来特别是插装式阀的发展,二通锥阀的使用愈益增多,但流体流过锥阀所形成液动力的研究还很不够。在理论分析方面,传统的锥阀液动力计算公式只有在外流式工作状态是正确的。对内流式工作状态,目前在国内外连对液动力作用方面的认识都还很不一致。在试验研究方面,工
As we all know, when the fluid flows through the spool, the hydrodynamic force generated by the spool has a great influence on the work of the spool, and its research has always been an important issue of hydraulic fluid mechanics. In recent years, especially the development of cartridge valve, the use of two-way cone valve is increasing, but the fluid flow through the cone valve formed hydrodynamic research is not enough. In theoretical analysis, the traditional calculation formula of hydraulic power of cone valve is correct only in outflow working condition. For the working status of internal flow, the current understanding of the role of hydrodynamics at home and abroad is still very inconsistent. In experimental research, workers
