随着工业自动化水平的不断提高,壳牌煤气化常压输送阀在工业生产中的作用越来越重要。然而,由于阀门的复杂结构和长期运行,阀门故障在所难免。针对壳牌煤气化常压输送阀的故障处理及解决方案进行研究对比。介绍了壳牌煤气化常压输送阀的工作原理和故障率统计。技改后的安装示意图以及原来在线使用2台盘阀故障率高原因分析、应对措施,仍然存内部零件脱落的风险,在线使用1台夹板阀故障率低原因分析、夹板阀具有的一些属性、性能特点。提出了预防措施,以避免类似故障再次发生。通过实践运行情况,低磅级150 LB夹板阀在生产常压输送阀系列中取得良好的运用效果,夹板阀是解决常压输送的优先选择替代方案之一。最后,总结了壳牌煤气化常压输送阀故障处理及解决方案的实际成果,并提出了进一步的研究方向。

With the continuous improvement of industrial automation level,the Shell Coal Gasification Normal Pressure Transportation Valve plays an increasingly important role in industrial production.However,due to the complex structure and long-term operation of the valve,valve failure is inevitable.This article focuses on the failure treatment and solutions of the Shell Coal Gasification Normal Pressure Transportation Valve.Firstly,this article introduces the working principle and failure rate statistics of the Shell Coal Gasification Normal Pressure Transportation Valve.The modified installation diagram is shown,as well as the reasons analysis and countermeasures for the high failure rate of two online installed disk valves,and the low failure rate of one online used clamp valve.The attributes and performance characteristics of the clamp valve are also discussed.Preventive measures are proposed to avoid similar failures from happening again.Through the practical operation of our company,the 150LB clamp valve has achieved good results in the production of normal pressure transportation valve series,and clamp valve is one of the priority alternatives for solving normal pressure transportation.Finally,the practical results of the failure treatment and solutions of the Shell Coal Gasification Normal Pressure Transportation Valve are summarized,and further research directions are proposed.
