The utility model discloses a system for it causes oil to worsen to solve steam turbine shaft -packing leakage entering bearing box has solved the steam turbine and need not take off the problem that steam turbine axle head hourglass vapour was handled to the jar, the operation of unit long period safety and stability. The utility model discloses contain by the high pressure cylinder of vapor seal, intermediate pressure cylinder, low pressure jar, supply the female pipe of vapour, airtight type oil catch, backsteam pipeline, supply to be equipped with on the female pipe of vapour electronic isolation gating, electronic isolation gating will supply the female pipe of vapour to fall into high pressure satage to supply female pipe of vapour and low pressure stage to supply the female pipe of vapour, and the vapor seal passes through high pressure satage and supplies the female pipe of vapour and assist vapour to supply the female pipe electrical control valve of vapour, main vapour to supply the female pipe elec
