The invention belongs to airplane fuel oil supply technologies, and relates to improvement of an airplane main oil tank pressure-maintaining vent system. The improved airplane main oil tank pressure-maintaining vent system is characterized in that a left ventilation connecting nozzle connecting pipe (2), a first communication pipe (3), a four-way part (23) and a static pressure transducer (24) are arranged in a main oil tank connecting nozzle communication pipeline, and an electromagnetic valve (11), a second ventilation pipe (16), a second tee joint (17), a fifth hoop (18), a third hose (19), a sixth hoop (20), a third ventilation pipe (21), a vacuum valve (22), a fourth ventilation pipe (25) and a vent hole (26) are arranged in a ventilation pipeline. By means of the improved airplane main oil tank pressure-maintaining vent system, the high-altitude oil supply performance of an oil tank is improved, and the ceiling of an airplane is further improved.
