Device for judging magnitude of response power of energetic material

The invention discloses a device for judging the magnitude of the response power of an energetic material. The device comprises an explosion chamber; a sample tank is arranged in the explosion chamber; a pressure relief hole is formed in the top of the explosion chamber; a blocking column is arranged in the pressure relief hole; two groups of grating sensors are arranged above the explosion chamber; the two groups of grating type sensors are connected with a timing display. The device comprises an electric ignition device; the electric ignition device comprises an electric ignition controllerand an initiating detonator. According to the device for judging the magnitude of the response power of the energetic material, the energetic material generates pressure at the moment of response to enable the blocking column to move upwards by a certain height; the grating type sensors record the passing time of the blocking column, so that the average speed of the blocking column is calculated;the average speed value of
