FIELD: nuclear power engineering.
SUBSTANCE: proposed drive has shell held at primary coolant pressure. Drive also has bar displacement mechanism mounted on shell collar and secured by means of snap ring and keys. Sealing device of shell gate valve has sensor case flange and cylindrical gasket. The latter is disposed between sealing surfaces of sensor case flange and shell. Bottom ring of hold-down device of shell gate valve abuts against semi-rings. The latter are mounted in drilling on outer surface of shell.
EFFECT: enhanced strength and performance characteristics of drive.
