Abstract: The mathematical model of dual sealing structure system is formulated. The conclusions of the relationship of the leakage rate, amount of leakage and time, and their influence factors are disclosed by theoretical analysis and numerical computation. These research results can be used as a guiding principle in design, leakage detection and leakage safety evaluation of the dual sealing system, to direct practice.
