The invention relates to the technical field of air tightness detection of closed equipment in civil air defense engineering, and discloses an air tightness detection system for closed equipment in civil air defense engineering, which comprises a detection data acquisition module, a detection data analysis module and a result output unit. According to the airtight equipment airtightness detection system in the civil air defense project, gas flow values are collected through two different collection units, the gas leakage amount and the gas leakage amount contrast value are calculated according to different formulas, and the two values are compared with the gas leakage amount threshold value; when only any one numerical value exceeds the gas leakage amount threshold value, it is judged that the related sensing unit breaks down, a fault signal is sent out, and the gas leakage amount and the gas leakage amount contrast value are calculated for mutual reference, so that the accuracy of the judgment result can be
