軸シール装置及びこれを備える回転機械
Document Type and Number:
Japanese Patent JP5804893
Kind Code:
B2
Abstract:
A shaft sealing device is provided in an annular space between a rotor and a stator surrounding an outer periphery of the rotor, and divides the annular space in the direction of an axis of the rotor into a high-pressure region and a low-pressure region. The shaft sealing device includes a seal body obtained by stacking a plurality of thin plate sealing pieces, which extend from the stator toward a radial inner side of the rotor, in a circumferential direction of the rotor; and a high-pressure side plate that extends from the stator toward the radial inner side so as to run along the high-pressure side of the seal body, and is segmented into a plurality of portions in the circumferential direction, and includes a rigidity imparting member configured to impart rigidity in the direction of the axis to a portion of the surface of the high-pressure side plate that faces the high-pressure region.
