成果简介	NOVELTY - The device has a hollow support (1) that is placed on a cover (2) of the pressure tank, in which a window (3) is made for access to a nut (4) for fastening the cover of the pressure tank. A hydraulic cylinder (5) is mounted on the hollow support with a first piston (6) connected to a stud (7), a second piston (8) connected to the first piston, and compensation cavities of the return stroke between the first and second pistons. A system is provided for supplying working fluid and is formed by channels located on the end and in the structure of the first piston. A distributor (10) is mounted on the first piston for regulating the supply and discharge of working fluid into the cavities of the hydraulic cylinder. An indicator stand (9) is designed with the ability to measure the amount of extension of the stud. USE - Device for pulling out stud during compacting and uncompacting of cover of pressure tank in nuclear power plant. ADVANTAGE - The device ensures the pulling out of studs by an equal amount at the same working pressure regardless of deviations in the mechanical properties of the studs, tolerances for the manufacture and assembly of devices for pulling out studs, the structure of the pressure tank into which the studs are screwed, and the studs. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the device for pulling out stud during compacting and uncompacting of cover of pressure tank in nuclear power plant. 1Hollow support 2Cover of pressure tank 3Window 4Nut 5Hydraulic cylinder 6First piston 7Stud 8Second piston 9Indicator stand 10Distributor
