Abstract

PURPOSE: To prevent external leakage of liquid in the valve by installing a seal box above the bonnet and using a bellows to seal off the penertration of the valve handling shaft into the seal box.
CONSTITUTION: A seal box 10 is installed above the bonnet 2, and a bellows 15 between the valve handling shaft 16 and the seal box 10. A water-tight sealing being established by this bellows between the inside of the seal box 10 and the outside, there remains no possibility for liquid flowing withing the valve to leak outside even when liquid leaks throuh the packing of the valve.
