The invention discloses a multi-path supercooling filling system and method for low-temperature propellants, and belongs to the field of supercooling filling of the low-temperature propellants. Vacuumizing treatment is carried out on a negative pressure module of a two-stage supercooling device by utilizing an evacuating and decompressing device, so that the temperature of a coolant in a cold source tank car is reduced; a two-stage supercooling device is adopted to carry out supercooling treatment on the propellant in the propellant tank car stage by stage, so that the supercooling operation of the propellant is realized; the supercooled propellant is conveyed to the rocket storage tank through the ground storage tank or the combination of the ground storage tank and the negative pressure module, so that different filling requirements of medium and small flow filling and large flow filling are met; the output end of the rocket storage tank is connected with the input end of the rocket storage tank through the negative pressure module to form a propellant recooling loop, recooling treatment of propellants in the rocket storage tank is achieved, and therefore the filling requirement after a launching task is delayed is met; according to the system, continuous and efficient treatment of propellants is achieved, and the adaptability of the system to emergencies and special filling requirements is enhanced.

    本发明公开了一种低温推进剂多途径过冷加注系统及方法,属于低温推进剂过冷加注领域,利用抽空减压装置对两级过冷装置的负压模块进行抽真空处理,从而降低冷源槽车中的冷却剂的温度;采用两级过冷装置对推进剂槽车中的推进剂逐级进行过冷处理,从而实现推进剂过冷操作;通过地面储罐或者地面储罐与负压模块的组合将过冷推进剂输送至火箭贮箱,从而满足中小流量加注和大流量加注的不同加注需求;将火箭贮箱的输出端通过负压模块与火箭贮箱的输入端相连,形成推进剂再过冷回路,实现了火箭贮箱中的推进剂再过冷处理,从而满足发射任务推迟后的加注需求;本系统实现了对推进剂的连续、高效处理,增强了系统对突发情况和特殊加注需求的适应性。
