FIELD: heat-and-power engineering.
SUBSTANCE: invention relates to the heat power engineering, namely to the steam turbines sealing devices. Disclosed is the honeycomb seals simpler analog. In the installed in the stator steam turbines segmental seals, the working part represents perforated surface in the form of depth-profiled round holes with sharp edges.
EFFECT: disclosed segmented seals have the following advantages over honeycomb seals: simplicity of manufacturing and accordingly less cost, convenient simple fixing in the stator circumferential grooves, sealing capacity is not inferior to the honeycomb seals.
