The invention provides a metal diaphragm storage box for a leap device and a manufacturing and assembling method of the metal diaphragm storage box. The metal diaphragm storage box comprises a gas path shell, a liquid path shell, a metal diaphragm, a composite material winding layer and a porous plate. The gas circuit shell is mainly integrally formed by a connecting ring, a gas circuit hemisphere and a gas circuit connecting nozzle and is provided with a perforated plate. The liquid path shell is mainly integrally formed by a shell flange, a liquid path hemisphere and a liquid path mouthpiece; the problems of metal diaphragm fatigue fracture and flange deformation caused by long-term storage and work of the leap device on the lunar surface with huge temperature change are solved, the problem of thin-wall shell force bearing design caused by flange offset design due to narrow space layout of the leap device is solved, and the requirement for light weight of a leap device propelling system is met.

    本发明提供了一种飞跃器用金属隔膜贮箱及其制造及装配方法,包括:气路壳体、液路壳体、金属隔膜、复合材料缠绕层及多孔板。气路壳体主要由连接环、气路半球、气路接嘴一体成型并安装有多孔板;液路壳体主要由壳体法兰、液路半球、液路接嘴一体成型;本发明整体解决了飞跃器在温度变化巨大的月面长期存贮及工作带来的金属隔膜疲劳破裂及法兰变形问题、由于飞跃器狭小空间布局导致法兰偏置设计带来的薄壁壳体承力设计问题,且满足了飞跃器推进系统的轻质化需求。
