本文提出了一种新的数字调压阀节流机构──孔交叉式节流机构，在对普通电磁调压阀静动态特性分析的基础上，建立了数字调压阀的传递函数模型。这一模型可作为数字调压阀设计过程中性能分析和参数优化的依据以及控制系统设计的参考。
This paper presents a new digital pressure regulating valve throttling mechanism ─ ─ cross-orifice throttling mechanism. Based on the analysis of the static and dynamic characteristics of the ordinary electromagnetic pressure regulating valve, the transfer function model of the digital pressure regulating valve is established. This model can serve as a reference for performance analysis and parameter optimization in the design process of digital pressure regulating valve and control system design.
