FIELD: power engineering. SUBSTANCE: invention relates to turbines being essentially one of main parts of steam distribution arrangement of turbine designed for fitting in spindle (rod) with valve. Proposed bearing sleeve of adjusting valve is mounted in steam cover and is provided with hole along axis to direct rod-spindle, and channel to feed live steam, and lower guide of valve. Valve guide serves as protective wall from dynamic forces of side steam flow action onto valve. Bearing sleeve is provided with slots dividing its guide lower part into springy lobes preventing wedging and getting of valve from core of flow. EFFECT: reduced coefficient of friction, improved repairability of valve, reliability and increased service life. 6 dwg
