Beschreibung
Zusammenfassung:	FIELD: mechanical engineering. ^ SUBSTANCE: invention can be used for sealing gas-air duct of gas-turbine plant operating in gas-transfer sets of gas-turbine power plants. Proposed sealing device for parts of gas-air of gas-turbine plant in which one part in direction of flow is enclosed in other part with clearance contains sealing elements overlapping the clearance. Said sealing elements are made in form of segments movable interconnected by slots and projections made on their end faces. Slots are L-shaped, being arranged, together with projections, at side adjoining end face of female part of gas-air duct. Height of projections is more than 2 tomes greater than clearance between male and female parts. Summary clearance between end faces of segments exceeds value of difference in perimeters of male part at minimum and maximum temperatures in service. Segments are spring-loaded to sealed surfaces and in L-shaped slot. ^ EFFECT: improved reliability of sealing of connected gas-air duct parts. ^ 3 dwg
