煤化工中氧气控制阀选用的安全措施

Safety Measures for Oxygen Control Valves Selection in Coal Chemical Industry

针对《空分装置安全运行规定》中的条款,应重视氧气阀门的安全操作,采取安全防范措施,避免因流速过快等原因发生爆炸。介绍了煤化工项目工程设计阶段对氧气控制阀材料的选择上的重要性。通过对氧气介质的流速分析,给出了氧气用控制阀阀体和阀芯材质选用的安全措施,在源头上解决流速过快可能引发的爆炸问题;对氧气控制阀出厂检验提出要求,同时给出阀体材质和阀芯材质的匹配的建议,强调了氧气阀门在操作时的注意事项。

According to iterms in Provisions on Safe Operation of Air Separation Unit, safe operation of oxygen valves should be stressed. Feasible safety measures should be taken to avoid explosion caused by excessive oxygen flow rate, etc. Importance of selection of oxygen control valve material in design stage for coal chemical project is introduced. Based on analysis of oxygen flow rate, safety measures for material selection of body and trim for control valve are proposed. Possible explosion caused by excessive oxygen flow rate is solved from the beginning. Control of factory inspection requirements of oxygen valve is raised. Recommendations on material matching for valve body and trim are given. Precautions in operation of oxygen valve is stressed.
