SEAL STRUCTURE

PROBLEM TO BE SOLVED: To provide a seal structure for sealing an annular gap formed between a high-pressure steam space and an adjacent low-pressure steam space.SOLUTION: In a seal structure, an annular gap 14 is defined between two casings 10, 11, and each casing is split into two halves. A seal el...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a seal structure for sealing an annular gap formed between a high-pressure steam space and an adjacent low-pressure steam space.SOLUTION: In a seal structure, an annular gap 14 is defined between two casings 10, 11, and each casing is split into two halves. A seal element of the seal structure is formed in a segmented and annular manner, extends between two casings, and engages in an annular receiving groove by means of a radial end region. The seal structure has segmented rings, a first circumferential surface of the ring is attached to one of the casings in the region of the annular gap 14, and an opposite second circumferential surface of the ring has an annular receiving groove or in a one-piece form with the annular seal element. 【課題】高圧蒸気空間と隣り合う低圧蒸気空間との間に形成された環状の間隙を密閉するためのシール構造体を提供する。【解決手段】シール構造体は環状の間隙１４が２つのケーシング１０，１１の間に形成されケーシングが２つの半体に分割されシール構造体のシール要素が分割された環状に形成され２つのケーシングの間において延在しラジアル方向端部領域のラジアル方向端部領域により環状の受容溝に係止されシール構造体が分割されたリングを有しリングの第１の周面が環状の間隙１４の領域で一つのケーシングに取り付けリングの反対側の第２の周面が環状の受容溝を備えるか環状のシール要素と一体化する。【選択図】図１
