气体灭火系统选择阀动作反馈开关的设计

Design of Selective Valve Action Feedback Switch for Gas Fire Extinguishing System

摘要: 通过对气体灭火系统的选择阀动作反馈装置的研究比对，进行了新型动作反馈装置的研究开发和试用，不断尝试安装位置和支架的距离，该动作反馈装置可以安装在任一规格的正压活塞杠杆式选择阀，解决了近15年来该阀门无动作反馈的空白，也满足了近年来多个规范的设计要求。

Abstract: Through the research and comparison of the action feedback device of the selective valve in the gas fire extinguishing system, a new type of action feedback device has been developed and tested, and the distance between the installation position and the bracket has been continuously tried. The action feedback device can be installed in any specification of the positive pressure piston lever type selective valve, which solves the problem that the valve has not moved in the past 15 years. The blank of feedback also meets the design requirements of many specifications in recent years.
