Abstract: The defects in design and manufacturing of the heatsupplying extraction control valve of the gassteam combined cycle turbine were analyzed. The reasons causing the transition connector screw rod of the piston rod of the hydraulic servomotor to bend during startup were found. The defects treatment concrete measures were given, and the normal operation of the extraction control valve was ensured.
Key words: gas-steam combined cycle unit, gas turbine, steam extraction control valve, transition connector, defect
