The jet fuel cabin high-speed ventilation valve for the ship comprises a pressure valve assembly and a vacuum valve assembly, the pressure valve assembly comprises a pressure valve body, a pressure valve rod, a valve disc and a punching and lifting disc, and the pressure valve body comprises a pressure valve upper valve body, a pressure valve middle valve body and a pressure valve lower valve body which are vertically arranged in sequence from top to bottom and communicate with one another; the top of the pressure valve upper valve body is communicated with the outside, and the bottom of the pressure valve lower valve body is installed on a vertical ventilation pipeline and communicated with the ventilation pipeline. The pressure valve rod is installed on the central axis of the pressure valve body and can vertically move in the pressure valve body. And the centers of the punching and lifting disc and the valve disc are fixed on the pressure valve rod. The invention further discloses a jet fuel cabin ventilation system for the ship. The high-speed breather valve has the beneficial effects that the punching and lifting disc is additionally arranged, the valve can be quickly started, jumped and exhausted during medium and small flow, the valve can stably fall back after being exhausted, and the operation safety of the high-speed breather valve is greatly improved.

    本发明公开了一种舰船用喷气燃料舱高速透气阀,包括压力阀组件和真空阀组件,所述压力阀组件包括压力阀体、压力阀杆、阀盘和冲升盘,所述压力阀体包括自上而下依次竖直布置且连通的压力阀上阀体、压力阀中阀体和压力阀下阀体;所述压力阀上阀体的顶部与外界连通,所述压力阀下阀体的底部安装在竖直的透气管路上,且与透气管路连通;所述压力阀杆安装于压力阀体的中心轴线上,且可在压力阀体内部竖向移动;所述冲升盘和阀盘均位于压力阀中阀体内,二者中心固定在压力阀杆上。本发明还公开了一种舰船用喷气燃料舱透气系统。本发明的有益效果为:增加冲升盘,实现了中小流量时阀门快速启跳和排气,排气后也能平稳回落,大大提高了高速透气阀作业安全。
