气动蝶阀开启动作延迟问题分析及处理

Pneumatic Butterfly Valve Opening Delay Problem Analysis and Processing

分析了某电厂失气开气动蝶阀多次发生失气开启动作延迟问题的原因,介绍了改进阀门及气动装置结构、增大阀门弹簧力、减小密封面过盈量和增加拉杆机构等措施解决故障的方法。

This paper analyzes the causes of the delayed opening action of the air-losing butterfly valve for many times in a power plant,and introduces the methods to solve the problems by improving the valve and pneumatic device structure,increasing the spring force of the valve,reducing the interference of the sealing surface and increasing the pull rod mechanism.
