METHOD FOR LOW-ENERGY CONTAINMENT CONTROL AND DEVICE FOR REALIZATION OF SAID METHOD

摘要

FIELD: containment control technologies.;SUBSTANCE: method includes determining value of gas flow from test subject on basis of amount of previously balanced vacuumized liquid, forced during determined time range by flowing gas from vertically positioned pipe, having a draw plate at end with control aperture, connected to output rod of vacuum chamber, and on basis of amount of pre-balanced vacuumized liquid, forced during certain time scale by flowing gas from second vertically positioned pipe with a draw plate with control aperture at an end, connected to hollow, formed by compacting surfaces of two-barrier compaction, mounted at joint of lid and body of vacuum chamber, penetrability of vacuum chamber is detected and correction of penetrability of test subject is applied, both pipes are filled concurrently with draining of vacuum chamber by immersion of draw plates of both pipes into tanks with control liquid for time of draining, and draining with following disconnection of pipes is performed until reaching pressure determined by formula P_vc = P_a-ρ*g*H_c, where P_vc - pressure in vacuum chamber; P_a - atmospheric pressure; ρ - control liquid density; g - free fall acceleration; h_c - height of liquid column in a tank.;EFFECT: higher precision, higher personnel safety, higher speed of operation.;2 cl, 1 dwg
