FIELD: nuclear technology.
SUBSTANCE: invention relates to nuclear technology, and more specifically to connections of vacuum pipelines of diagnostic systems of thermonuclear plants. A device for the detachable connection of pipelines includes support case (1) containing connecting system (2) for attaching support case (1) to first pipeline (3) and second connecting system (8). Second connecting system (8) is made in the form of two opposite half-rings (9), which are connected by rods (11) passed through walls of support case (1) with pneumatic cylinders (12) fixed on the outer surface of support case (1). Actuator (15) contains annular pneumatic jack (19) and annular wedge (20) coaxially mounted on spline flange (16) attached to second end face (17) of support case (1).
EFFECT: device provides reliable sealing of connected pipelines in conditions of strong radiation exposure to fast neutrons and gamma quanta, large heat flow from plasma, exposure to emergency loads.
