摘要/Abstract

摘要： 为了解决螺线管电磁阀开启响应和关闭响应难以同步提高的问题，提出一种基于能量回收原理的高速电磁阀，通过特殊的高刚度回复片弹簧及其与衔铁顶杆的微小间隙设计，实现了密封力与回复力的解耦，在不影响开启过程的情况下将衔铁动能转化为加速关闭的弹性势能。在分析了高速电磁阀工作原理基础上，利用Ansoft Maxwell软件对其瞬态特性进行了仿真分析，并对不同结构参数电磁阀的开关响应特性进行了对比试验研究。试验结果表明，高刚度回复弹簧及其间隙δ的存在将高速电磁阀的关闭时间缩短了6ms左右，而开启时间仅延长了0.3ms，开关时间均可控制在5ms以内并且具有100万次以上的开关寿命。

Abstract: In order to solve the problem that the opening response and the closing response of solenoid valve cannot be improved synchronously, a high-speed solenoid valve based on the energy recovery principle is proposed, which adopts a special high-stiffness return spring that has a small gap with the armature. It decouples the sealing force and the closing force. The kinetic energy of the armature is converted into the elastic potential energy that accelerates the armature closing process without affecting the opening process. Based on the analysis of the working principle of high-speed solenoid valve, its transient characteristics were simulated by Ansoft Maxwell and the switching response characteristics with different structural parameters were tested. The presence of both the high stiffness return spring and its gapδ could shorten the closing time by about 6ms, while the opening time is only extended by 0.3ms. The switching time can be controlled within 5ms and has more than 1 million switching times.
