文中将工程中对比例减压阀的要求转换成水力学的要求。通过进一步的水力学原理分析,得出比例减压阀设计的技术关键,乃是狭缝的宽度。文中给出了实现技术关键时应注意之点。文中还给出了比例减压阀的总装示意图以及作者设计和制造的比例减压阀的水力特性曲线。並同澳大利亚国际专利产品的水力特性曲线作了对比。
The article will be the project to convert the requirements of the proportional valve into the hydraulic requirements. Through further analysis of the principle of hydraulics, draw the key technology of the proportional pressure reducing valve design, but the width of the slit. The article gives the key points that should be paid attention to when realizing the key technology. The paper also presents the assembly of the proportional valve schematic and the hydraulic characteristics of the proportional valve designed and manufactured by the author. It is compared with the hydraulic characteristics of Australian patented products.
