控制阀是石油化工罐区中的主要元件之一,它的安全性能是衡量阀门质量优劣的重要指标,阀门检验标准中对阀门的安全等级有明确的规定.通过对控制阀的类型与结构分析,并在工程设计中充分考虑其使用工况,使控制阀在石油化工大型罐区中尤其在安全方面能够合理的进行选型及应用,力求选用的阀门满足安全、合理和经济的原则.%Control valves are main component in oil chemical tank farm. Safety performance of the valves is an important index of quality. The security level in inspection standards for valve has specific provision. In this paper, through analyzing types and structures of control valves and considering its operating conditions in engineering design, suitable control valves were selected and used in petrochemical industry large tank farm in terms of security, reasonable and economic principles.
