The invention relates to separation and reclamation of low-temperature liquid, and discloses a gas-liquid separation and transfer device. The device comprises an upper container and a lower container which are positioned in an outer container; a pneumatic electromagnetic valve V1 is arranged between the upper and lower containers; a supercharger and an automatic control system for counting the transfer quantity of the liquid are arranged in a pipeline; and a liquid level sensor and a pressure transmitter are arranged in the upper and lower containers. A valve V2 is arranged in a liquid inlet pipeline of the upper container; a low-temperature check valve V7 and a safety valve V8 are arranged in a discharge pipeline of the upper container; and a transfer output valve V6, and valves V3, V4, V5 and V9 controlled by the pneumatic electromagnetic valve are arranged in a discharge pipeline of the lower container. The device solves the problems of few reclaiming paths, high investment, low automation degree and the like when the low-temperature liquid is applied in the prior art. The device achieves the effects of reducing the low-temperature liquid delivery and spatial environment simulation test costs, improving the use safety of the low-temperature liquid and the like.
Description
technical field [0001] The invention relates to the separation and recovery of cryogenic liquid, in particular to a gas-liquid separation transfer device. Background technique [0002] The space simulator is a ground test device for vacuum thermal experiments on spacecraft by simulating the vacuum of space, cold darkness and solar radiation. The cold and dark environment is one of the important environments simulated by the space simulator. After more than 40 years of development of space cold and dark environment simulation technology at home and abroad, the following design schemes have been formed: open boiling system, pressure throttling circulation system, single-phase closed circulation system, and the popular gravity water circulation system in recent years. self-circulation system, etc. [0003] The thermal vacuum test cycle is quite long and consumes a lot of manpower, material and financial resources. A large-scale space environment simulator consumes about ten t...
