双向气动快速开关阀动态特性分析

摘要/Abstract

摘要： 基于ADAMS对双向气动快速开关阀启闭过程进行动力学仿真，同时使用AMESim模拟气动缓冲装置的最佳安装位置，设计出以自主研发的双向冲击气缸为动力的双向快速开关阀。分析结果表明，在0.7MPa气源压力下，双向气动快速开关阀开启、关闭时间一致，均为0.038s；将气动缓冲装置安装在活塞杆前端距动力转换装置初始点20.5mm处可有效避免因冲击过快导致的阀板撞击阀座而引起的部件破坏；阀轴在开关启闭过程中转速过快，轴向存在位移，设计阀门时需注意这一点。研究结果为易燃易爆介质场合使用的垂直板式蝶阀的设计提供了参考。

Abstract: A dynamic simulation for opening and closing processes of a high-speed switch valve was set up herein. At the same time, using AMESim simulation pneumatic buffer device to simulate the optimal installation location, a two-way pneumatic high-speed switch valve was designed with the power of self-developed two-way impact cylinder. Analysis results show that, under the air pressure 0.7MPa, the two-way moving high-speed switch valve's opening and closing times are in consistent, they are all 0.038 seconds. If the valve plate impacts valve seat too fast, the components will be damaged. The distance between the pneumatic cushioning device and the front end of the piston rod should be as 20.5mm,both devices are connected by the power conversion device. It is worth mentioned that the speed of valve shaft too fast during the process of switch opening and closing can cause axial displacement. The results provide a reference for design of vertical plate type butterfly valve used in flammable and explosive medium.
