Abstract

PURPOSE: To simplify the feed pipe line of sealing liquid, by providing a gap and a pressure reducing chamber between a casing and a stuffing box and feeding sealing liquid at suitable pressure from a sealing hole of the stuffing box to a shaft sealed part.
CONSTITUTION: A rotary shaft 2 is arranged in such a manner as to be extended through a casing 1, and a gland packing 4 and lantern ring 5 are equipped to the periphery of a sleeve 3 surrounding the rotary shaft 2. Then between the casing 1 and a stuffing box 6, a gap 9 and a pressure reducing chamber 8 for reducing the pressure of sealing liquid are provided, further a sealing hole 10 for communicating the lantern ring 5 to the pressure reducing chamber 8 and a sealing liquid flow inlet 11 are bored in the outside of the pressure reducing chamber 8. The sealing liquid flowing into the pressure reducing chamber 8 through the inlet 11 is reduced its pressure by adjusting the gap 9 and supplied to between the gland packing 4 and the sleeve 3 through the sealing hole 10 and the lantern ring 5.
