FIELD: nuclear engineering, namely closing of ports of significant dimensions.
SUBSTANCE: gate valve includes body, guides and locking organ. The last is in the form of set of rod members mutually coupled with possibility of turning to one side. Said coupling is formed by means of links of fork chain secured to end surfaces of rod members. In rotation pins of links of fork chain runners are mounted; said runners are engaged with guides of gate valve body.
EFFECT: possibility for compact arrangement of movable members of gate valve in limited space, improved operational reliability, enhanced radiation safety of gate valve.
