HYDRAULIC DRIVE SYSTEM OF THE CONTROL VALVES OF THE PRODUCTION LINE Russian patent published in 2023 - IPC F16K47/02 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, in particular to valve engineering, namely to control valves, and can be used in the oil and gas industry. The hydraulic drive system of the control valves of the production line, including two hydraulic cylinders that drive reciprocating carriages with ratchets rotating the output shaft of the drive by means of ratchet wheels, return springs of the carriages, ball position locks interacting with a copier mounted on the output shaft of the drive, the emergency rotation shaft of the drive from a remote-controlled uninhabited underwater vehicle with a rotary tool installation cup coaxially connected to the output shaft, and one of the ratchet wheels is made of two parts, symmetrically placed relative to the axis of the rod, the carriage is driven by a two-rod double-acting hydraulic cylinder with a spring located in the rod cavity on the side of the carriage, the hydraulic cylinder rods have different diameters, while the rod, which does not interact with the carriage, has a larger diameter and is connected to the drive housing filled with hydraulic fluid.

EFFECT: implementation of discrete angular displacement of the output valve link while maintaining dimensions, as well as increasing reliability by minimizing the amount of hydraulic equipment used in the control scheme and changing the kinematic drive scheme.
