A static gear meshing device with a one-stage flow priority valve bank comprises the one-stage flow priority valve bank, a rotating speed signal input end, an air pressure signal input end, a frequency/voltage converter, a first AD converter, a second AD converter and an AND gate. The rotating speed signal input end is connected to the AND gate through the frequency/voltage converter and the first AD converter, and the air pressure signal input end is connected to the AND gate through the second AD converter; an electromagnetic valve is connected to the one-stage flow priority valve bank. The static gear meshing device with the one-stage flow priority valve bank is high in reliability, and capable of effectively protecting a transfer case.
