Firstly, the assembly process is very complicated, an operator needs to sequentially pass dozens of groups of bolts through the multi-layer plate body and screw the bolts step by step according to a specific sequence by means of a torque wrench, poor lamination between layers can be caused by uneven pretightening force of any bolt, meanwhile, the micro-hole flow channels on the multi-layer plate body need to be accurately centered, melt distribution disorder or composite section distortion can be caused by any tiny assembly deviation, and the experience dependence on the operator is high. Secondly, the leakage state cannot be identified in a grading manner, when the inner sealing ring is slightly leaked, leakage objects are intercepted by the outer sealing ring and are retained in an annular cavity between the two sealing rings, but no state monitoring means are arranged in the cavity, operators are completely insensitive to the leakage states, and as the retention objects are carbonized at high temperature and accumulated in pressure, the outer sealing ring is finally suddenly disabled, so that the leakage of the melt is caused.
