摘要
快速开关是使压力容器迅速处于开启或关闭状态的装置,在呼吸器类的煤矿安全仪器上,压力容器的开关大部分都是小螺距,开启或关闭的速度慢;介绍了快速开关的工作原理和结构特征,通过与普通的螺纹开关的对比,快速开关在安全仪器上有着很好的应用前景。
Fast switching is the device that can make pressure vessel rapidly in open or closed, switch in the mine safety equipment such as respirator and pressure vessels is small pitch switch which is slow open or closed.
