浅析石油化工装置阀门密封原理及泄漏原因

Reasons of Leakage of Valve Sealing Principle in Petrochemical Plant

阀门是石油化工管道系统中必不可少的控制元件,是保护管路、实现装置安全有效运行的一个基本管路元件,对石化炼油装置而言,其正常运行至关重要。因此,阀门的密封好坏是衡量其性能的重要指标。基于此,文章通过对阀门密封原理的分析,重点阐述了阀门填料函和阀门外泄漏原因,讨论了目前所采用的改善方法。

Valves is the control element in petrochemical piping system, it can protect the pipeline, to achieve safe and effective operation of the equipment, its normal operation is very important for the plant. Therefore, the valve sealing performance is an important indicator to measure the performance of. Based on this, through the analysis of the valve sealing principle, the paper elaborated with emphasis the valve stuffing box and the leakage of the valve outside reason, discussed the method to improve it.
