Abstract

The invention provides a full-scale hydrazine propellant leakage detection system and method, and aims to solve the problems of test failure and safety accidents caused by leakage risks of existing hydrazine propellants in the processes of storage, transfer injection, filling and the like. The system comprises an acousto-optic infrared detector, a three-way electromagnetic valve, an electrochemical detector, a gas purging assembly and a control mechanism. The acousto-optic infrared detector is provided with a sampling point; an inlet end I of the three-way electromagnetic valve is communicated with an exhaust port of the acousto-optic infrared detector, a first outlet end of the three-way electromagnetic valve is communicated with an inlet end of the electrochemical detector, and a second outlet end of the three-way electromagnetic valve is communicated with the atmosphere; the outlet end of the electrochemical detector is communicated with the atmosphere through a first check valve; the gas purging assembly comprises a purging pump and a second check valve, one end of the second check valve is connected with the purging pump, and the other end of the second check valve is communicated with the inlet end of the electrochemical detector; and the control mechanism is used for controlling the actions of the three-way electromagnetic valve, the purging pump, the first check valve and the second check valve.

Description

technical field [0001] The invention relates to a leak detection technology for hydrazine propellants, in particular to a full-range leak detection system and method for hydrazine propellants. Background technique [0002] Hydrazine propellants are widely used as conventional liquid fuels for launch vehicles in the launch tests of various satellites and spacecraft. Hydrazine propellants have moderate or higher toxicity, and are flammable and explosive. [0003] In conventional rocket engine tests, the storage, transfer, and filling of hydrazine propellants are prone to the risk of leakage. Leakage of hydrazine propellants will pollute the environment and cause harm to operators (personnel poisoning and casualties), and even Trigger fire and explosion, resulting in the failure of the test and the occurrence of safety accidents. Therefore, it is urgent to design a hydrazine gas concentration detection and alarm system to realize real-time and accurate monitoring or inspection...
