Beschreibung
Zusammenfassung:	The supercritical gas turbine flow guide ring comprises an outer ring casting and an inner ring, and a first limiting groove and a second limiting groove are formed in the inner wall face of the outer ring casting; a first limiting protruding block is integrally arranged on the outer surface of the inner ring and inserted into the first limiting groove. An opening is formed in the position, aligned with the first limiting protruding block, of the inner ring, a limiting blocking block is arranged in the opening, and a sealing strip is arranged between the side face of the limiting blocking block and the inner wall face of the opening. A second limiting protruding block is integrally arranged in the middle of the outer surface of the limiting blocking block and inserted into the second limiting groove, a bolt through hole is formed in the second limiting groove, a stainless steel bolt is arranged in the bolt through hole, and the limiting blocking block is locked through the stainless steel bolt.
