The invention discloses a reconfigurable general airtight test device for an aircraft system. The reconfigurable general airtight test device comprises an air source module, a low-pressure module, a pressurization module and a high-pressure module, the gas source module and the two low-pressure modules which are connected in parallel are combined to form a pneumatic module configuration A, and the pneumatic module configuration A can provide two paths of 0-1MPa gas output; the gas source module is combined with a low-pressure module and a high-pressure module which are connected in parallel to form a pneumatic module configuration B, and the pneumatic module configuration B can provide one path of 0-1MPa gas output and one path of 0-13MPa gas output; the gas source module, a high-pressure module connected with a pressurization module in series and a low-pressure module connected with the high-pressure module in parallel form a pneumatic module configuration C, and the pneumatic module configuration C can output 0-1 MPa gas and 0-24 MPa gas in one path. The modular design is adopted, and output of different pressure ranges and branches can be achieved through combination of different modules; in addition, the airtight test device adopts a universal design concept, and continuous output of test pressure is realized by utilizing a PLC and a proportional pressure reducing valve.
