▎ 摘　　要

NOVELTY - The energetic container has shell whose upper end opening is connected with flange cover through transition section (2). The lower end opening of round spherical shell is provided with liquid discharging valve (10). The steel plate (13) is fixed at middle of inner layer shell (11) and outer layer shell (12). The bottom portion of steel plate is fixedly connected with inner layer shell and top portion is connected with outer layer shell. The maximum stress threshold value bear by fastener is less than maximum stress threshold value bear by stress removing steel belt (5). USE - Energetic container for preparing three-dimensional graphene-covered single-particle nano-diamond. ADVANTAGE - The local stress of the container is eliminated by stress-relief belt provided on the exterior of the housing, so the compressive strength of the housing of the energetic container is increased, and the durability of the energetic container is extended. The operator is allowed to control fluid intake valve and fluid drain valve of the housing, so operating process is simplified, operating time is reduced. Hence the labor intensity is reduced and production efficiency is increased. The installation, reliability and maintenance of the energetic container are improved. The quality of the energetic container is enhanced, and the requirements for large-scale production are satisfied. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the energetic container.
