    • 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.
    • 用于形成填料环(6)的环形段(100)。 该段包括与类似件相配合的弓形件,以在涡轮机(1)的相邻级与涡轮机的末端级(2)和大气之间形成有效的密封。 每个环段具有形成在段的每个端部处的步骤(14,15),用于将段与相邻环段接口。 台阶形成在环段的相对侧上,并且允许相邻段彼此容易地相互接合,因为在它们之间形成所产生的对接间隙(16)的过大。 这消除了组件环的返修,确保质量密封受到影响,并减少了涡轮脱机的时间。
