The invention discloses a chemical tanker and epoxypropane cargo hold, a ventilation system and a pressure safety valve locking device, the pressure safety valve locking device comprises a lower locking support, an upper locking support, a support sleeve and a locking piece, the lower locking support is oppositely arranged on a base flange of a pressure safety valve, and the upper locking supportis arranged on the base flange of the pressure safety valve. The upper locking support and the lower locking support are fixedly connected and form a containing space used for containing the pressuresafety valve together with the lower locking support, the supporting sleeve is fixed to the top of the upper locking support, and the locking piece is screwed into the supporting sleeve and locks thepressure safety valve in a closed state. The chemical tanker and epoxypropane cargo hold is simple in structure, convenient to install and use and high in reliability and safety, the pressure safety valve locking device does not need to be integrally disassembled in the voyage of loading different goods, meanwhile, the pressure safety valve does not need to be disassembled and replaced, and the leakage danger is reduced. The chemical tanker and epoxypropane cargo hold further has advantages of high reliability and high safety.
本发明公开了一种化学品船兼装环氧丙烷货舱及通风系统、压力安全阀锁定装置,所述压力安全阀锁定装置包括下锁定支撑、上锁定支撑、支撑套管和锁紧件,下锁定支撑相对设置在压力安全阀的底座法兰上,上锁定支撑与下锁定支撑固定连接并与下锁定支撑共同组成一个用以容纳压力安全阀的容纳空间,支撑套管固定在上锁定支撑的顶部且锁紧件旋入支撑套管并将压力安全阀锁定在关闭状态。本发明结构简单,安装、使用方便,在装载不同货品的航次中,无需整体拆卸本发明的压力安全阀锁定装置,同时不用拆卸更换压力安全阀,减少了泄露的危险,可靠性和安全性强。
