The invention discloses a high temperature and high pressure sealing window used for a constant volume combustion bomb. The high temperature and high pressure sealing window used for the constant volume combustion bomb comprises a flange end cover, wherein the external side of the flange end cover is provided with an external boss; the flange end cover and a constant volume combustion bomb body are fixed through installing bolts; glass is arranged inside the flange end cover; the external side of the glass is axially limited through a first sealing step surface which is arranged inside the flange end cover; the first sealing step surface is provided with a groove which is provided with an O type ring; the inner side of the glass is axially limited through a blocking ring which is fixed on a second sealing step surface which is arranged inside the flange end cover through countersunk bolts to compress the glass; and a graphite gasket is arranged between the blocking ring and the glass. According to the high temperature and high pressure sealing window used for the constant volume combustion bomb, the sealing is performed on the flange end cover and the constant volume combustion bomb body after the glass and the flange end cover are arranged into a whole, the glass is one-time installed, and frequent detachment is not needed, so that the problems that the sealing fails and the glass is easy to crush are solved. The gas expansion pressure inside a chamber enables pre-tightening force for compressing the glass to be enhanced to achieve the effect of self-tight sealing, so that the sealing of the high temperature and high pressure gas of the constant volume combustion bomb is achieved.
