Other AbstractThe utility model relates to an air-tight cabin charging and air-tightness detecting device which includes a charging pipeline and an air extracting pipeline which are selectively connected with the charging space of the air-tight cabin through a pipeline switching element the input end of the charging pipeline is connected with a charging bottle the output end of the air extracting pipeline is provided with a vacuum pump the charging pipeline after being provided with a filter, a charging valve, and a vacuum pressure meter in sequence on the air inlet direction, is switched in the pipeline switching element the air inlet end of the charging pipeline is also provided with a first self-locking joint the air extracting pipeline is provided with an air extracting valve, a vacuum meter and a vacuum pump in sequence on the air extracting direction and the air inlet of the vacuum pump is also provided with a second self-locking joint through a one-way valve. The utility model adopts the combined structure of air extracting and charging to continuously and alternatively implementing air extracting and charging on the air-tight cabin, extracts air first and then charges air, can reach the purification requirements very quickly, and has quick speed as well as high charging and air extracting efficiency.
