The pressurization system is characterized in that a partition plate is arranged in a propellant storage box and divides the propellant storage box into an upper part and a lower part, and the volume of the upper large storage box is larger than that of the lower partition plate storage box; a plurality of normally-open isolating valves are evenly distributed on the partition plate. A partition plate storage tank pressure sensor is arranged on the inner side wall of the partition plate storage tank, and a partition plate storage tank pressurizing energy dissipater is arranged in the partition plate storage tank; an exhaust pipeline communicated with the partition plate storage tank is arranged on the partition plate, and a partition plate storage tank safety exhaust valve is mounted on the exhaust pipeline; the partition plate storage box pressurization energy dissipater is connected with the pressurization gas cylinder through a partition plate storage box pressurization pipeline, and a pressurization electromagnetic valve is arranged on the partition plate storage box pressurization pipeline. And a large storage box pressurizing energy dissipater is arranged in the large storage box and is communicated with the large storage box pressurizing pipeline. The problems that due to repeated use, the pressurization gas amount of the return section is large, the requirement for bottom sinking is large, and the propellant temperature is high can be effectively solved.
本发明涉及一种基于隔板贮箱的增压系统,隔板设置在推进剂贮箱中,将推进剂贮箱分为上下两部分,上方的大贮箱容积大于下方的隔板贮箱容积;隔板上均布若干常开隔离阀。隔板贮箱内侧壁上设置有隔板贮箱压力传感器,内部设置有隔板贮箱增压消能器;隔板上设置有与隔板贮箱连通的排气管路,排气管路上安装有隔板贮箱保险排气阀;隔板贮箱增压消能器通过隔板贮箱增压管路与增压气瓶连接,隔板贮箱增压管路上设置有增压电磁阀。大贮箱内设置有大贮箱增压消能器,大贮箱增压消能器与大贮箱增压管路连通。本发明可有效解决由重复使用带来的返回段增压气量大、沉底需求大和推进剂温度高的问题。
