The invention discloses a standard motor-train-unit grid-type pressure wave protective valve which is a pressure wave protective device for achieving flexible sealing between a sealing rubber rod and a base-plate strip gap. Four guide columns (6) arranged on a base plate (1). An air cylinder installation base (8) is arranged at the upper portions of the guide columns (6). A movable rubber rod connecting plate (4) capable of vertically sliding in the axial direction of the guide columns (6) is arranged in the middles of the guide columns (6). The sealing rubber rod (2) is arranged below the movable rubber rod connecting plate (4). A special connecting block (7) is arranged on the movable rubber rod connecting plate (4). The upper face of the special connecting block (7) is connected with an air cylinder push rod of a spring resetting double-action air cylinder (9). The spring resetting double-action air cylinder (9) is fixed to the air cylinder installation base (8). By means of the standard motor-train-unit grid-type pressure wave protective valve, the pressure wave protective valve is flexibly closed, the impermeability of the valve is guaranteed, the noise generated by closing the valve is reduced, and the protective valve can be timely opened when normal pressure fluctuation is normal to guarantee the quality of the air in a carriage.
