摘要
某炼油厂新焦化装置稳定塔流量变送器的三阀组(由3个截止阀组成)在使用过程中发生构件断裂,通过对三阀组结构解剖、断裂构件受力分析及检测,探讨了构件断裂原因并提出改进意见。
The components of the tri-valve set ( combined with three shut-off valves ) of the flow transducer of the stabilizer column of the new coking unit in a refinery failed in application. The failure causes of the components were discussed and some improvements were proposed through the structure dissection of the tri - valve set, stress analysis of failure components, and inspection.
