Abstract

PURPOSE: To facilitate the mounting of a packing case for sealing steam, by newly manufacturing a shaft for sealing steam by shaving off a surface of a shaft of a water-seal portion and an impeller for sealing water, and by installing the packing case in conformity with the shaft for sealing steam.
CONSTITUTION: A packing case 7f for sealing steam is clamped to an inwall 8v of a casing with water-seal structure by means of a bolt 17, and a steam seal chamber 7g is mounted. Both pipes 16p, 16q for feeding steam s to the chamber 7g are welded 5w to a casing 8. The inwall 8v in a water-seal system is utilized in this manner, and a packing for sealing steam is installed outside the inwall.
