The invention discloses a plate valve type exhaust valve for a ram air inlet and a method. Comprising a valve shell, and a large plate, a small plate and an auxiliary plate are arranged at an air vent of the valve shell; the large plate is hinged to the valve shell through a large plate rotating shaft, the small plate is hinged to the valve shell through a small plate rotating shaft, and the auxiliary plate is located above the large plate and hinged to the large plate through an auxiliary plate rotating shaft. The large plate and the auxiliary plate are respectively provided with a large plate convex block and an auxiliary plate convex block which are close to each other at the auxiliary plate rotating shaft; a tension spring is also arranged between the large plate and the auxiliary plate; the valve shell is hinged to a first connecting rod, the first connecting rod is hinged to a second connecting rod through a first connecting rod output rotating shaft, the second connecting rod is hinged to a small plate through a second connecting rod output rotating shaft, the small plate is hinged to a third connecting rod through a small plate output rotating shaft, and the third connecting rod is hinged to a large plate through a third connecting rod output rotating shaft. The device is diversified in function and low in cost.
