摘要： Methods and apparatus for a packing ring segment assembly for sealing a turbine gas path are provided. The assembly includes a sealing portion including radially inwardly directed teeth, and a dovetail mounting portion including a hollowed out portion including a biasing member internal to the packing ring segment. The biasing member is coupled to the packing ring segment and configured to engage a pair of annular shoulders of a dovetail groove in the turbine such that the packing ring segment is biasing radially outward at relatively low turbine loads and low working pressure, and at relatively high turbine loads and high working pressure a working fluid overcomes the radial biasing member forces and urge the packing ring segment radially inward.

摘要： A packing ring in a multi-staged turbine that includes two ring segments joined by a dovetail feature. In some embodiments, the dovetail feature may include a male/female configuration. In other embodiments, the dovetail feature may include an insert/groove configuration. The insert of the insert/groove configuration may include a protrusion that extends from an approximately flat surface of an end of one of the ring segments. The groove of the insert/groove configuration may include a notch in an approximate flat surface of an end of one of the ring segments. The insert of the insert/groove configuration and the groove of the insert/groove configuration may be of a similar size such that the insert closely fits within the groove.

摘要： A ring segment (100) used to form a packing ring (6). The segment comprises an arcuate shaped piece interfitting with similar pieces to form an effective seal both between adjacent stages of a turbine (1), and an end stage (2) of the turbine and the atmosphere. Each ring segment has a step (14, 15) formed at each end of the segment for interfacing the segment with an adjacent ring segment. The steps are formed on opposite sides of the ring segment and allow adjacent segments to readily interface with each other because an oversize of resulting butt gap (16) is formed between them. This eliminates rework of the segments to assemble the ring, insures a quality seal is affected, and reduces the time the turbine is off-line.
