Tank performance requirements for valves
The author: Time:2020/12/11

        储油区包括储存油品的油罐以及输送油品的管网。油罐与油罐、油罐与泵房都是通过管网连通。通常是几个油罐共用两条油管,即所谓“双管系统”。油罐区中的阀门口径通常是比较大,阀门的操作次数比较少,阀门的使用环境比较恶劣,油罐底沉积的水份和固体杂质经常随油品流出,并沉积在阀底。其中油罐对于阀门的性能要求如下:
        (1)工作安全可靠:以防因阀门失效或损坏造成油中品泄漏。
        (2)密封性能好:以防因阀门内泄漏,造成串油事故。
        (3)耐冲蚀、抗擦伤性能好:以防油罐底沉积的固体杂质冲蚀、擦伤密封面。
        (4)阀门的结构应满足以下要求:流经阀门的杂质不会沉积在阀底,阀底有排污孔、能及时排除沉积于阀底的杂质。
