Abstract

PURPOSE:To equalize pressing force applied to each stage packing in a device and increase its sealing effect, by providing a communication passage, guiding a sealing fluid from a packing chamber at the precedent stage high pressure side to the back part of a packing at the low pressure side, in a partitioning wall of the packing chamber. CONSTITUTION:A passage 16, for guiding water leaking from a high pressure side packing 10B partially to a low pressure side packing chamber 6C, is formed in the inside of a separator wall 8 partitioning an intermediate stage packing chamber 6B and upper stage packing chamber 6C. Then cooling water qi fed through a feed water hole 13 at pressure Pi flows into the high pressure side packing chamber 6B to establish pressure P1. While cooling water leaking from the high pressure side packing chamber 6B partially flows into the low pressure side packing chamber 6C through the passage 16. Accordingly, packings 10B, 10C in the respective stage are loaded with almost equal difference pressures (P1- P2), (P2-Palpha).
