    摘要： A low leakage sealing system is provided between a steam pipe and a housing comprised of a pair of shells and a nozzle box movable relative to one another. The sealing system includes large and small diameter sealing rings engaging the pipe and shells or nozzle box and a secondary sealing element disposed between the sealing rings and one of the pipe and shells or nozzle box. The sealing elements comprise frustoconical elements having curved end surfaces forming primary seals with the sealing rings and the housing. In another form, the sealing system includes annular carrier elements having radially opening cavities for receiving sealing rings engageable with the pipe and housing, respectively. The carrier elements are axially spaced from a plurality of sealing rings to provide the low leakage sealing system.

    摘要： The positions of brush seal segments are positively adjusted relative to a housing carrying the brush seal segments and the opposing sealing component by employing members formed of thermally responsive material. The members are heated by heating elements receiving controlled power. By increasing or decreasing the power provided to the heating elements, the members are expanded or contracted to move the brush seal segments toward or away from the opposing sealing component.

    摘要： A rotary machine includes a rotatable rotor, blades radially mounted on and spaced apart about the rotor, a stationary casing disposed about and radially outward from the rotor and blades defining an annular gap between the casing and tips of the blades, and a flexible abradable seal assembly attached on the casing and disposed within the annular gap such that during differential growth of the rotor and blades relative to the casing the seal assembly flexes and abrades in response to contact by the blade tips and thereby clearance between the casing and blade tips is controlled as to avoid contact by the moving blade tips with the casing.

    摘要： In a gas turbine having a chordal hinge seal between an inner rail of each nozzle segment and an annular axially facing sealing surface of a nozzle support ring, a supplemental seal is disposed between the support ring and inner bands of the nozzle segments on a lower pressure side of the chordal hinge seals. To minimize or prevent leakage flow across the chordal hinge seals, a generally U-shaped supplemental seal having reversely folded U-shaped marginal portions is received in a cavity formed in the axially extending sealing surface of the inner rail of the nozzle segment. At operating conditions, the marginal portions seal against the base of the cavity and the annular sealing surface of the nozzle support ring to prevent leakage flow past the chordal hinge seal from entering the hot gas path. To install the supplemental seal, the seal is first compressed and maintained in a compressed state by applying one or more wraps about the supplemental seal or an epoxy to secure the seal when compressed in the cavity. At operating temperatures, the retention means releases the seal to engage marginal portions against opposite sealing surfaces of the nozzle segment and support ring.
