The invention provides a surface tension storage tank depletion isolation device, a working method and a surface tension storage tank. The surface tension storage tank depletion isolation device comprises a surface tension storage tank, a liquid level sensor, a three-way isolation pneumatic valve, a liquid pipeline and a driving gas pipeline, the surface tension storage tank is provided with a liquid level sensor, the liquid pipeline is communicated with the surface tension storage tank and the three-way isolation pneumatic valve, and the three-way isolation pneumatic valve is connected with the driving gas pipeline. During use, manual operation is not needed, the depletion state of the propellant in the storage tank can be rapidly and accurately judged through the liquid level sensor, the storage tank is isolated, and the system is suitable for a propulsion subsystem with strict unavailable propellant amount requirements in the surface tension storage tank.

    本发明提供了一种表面张力贮箱耗尽隔离装置、工作方法及表面张力贮箱,包括:表面张力贮箱、液面传感器、三通式隔离气动阀、液路管路以及驱动气管路;所述表面张力贮箱上安装液面传感器,所述液路管路连通表面张力贮箱和三通式隔离气动阀,所述三通式隔离气动阀连接驱动气管路。本申请在使用时无需人工操作,通过液面传感器可快速、准确判断贮箱内推进剂耗尽状态并隔离贮箱,适用于表面张力贮箱内推进剂不可用量要求严格的推进分系统。
