HYDRAULIC PLATE UNDERWATER CONTROL UNIT Russian patent published in 2021 - IPC E21B33/35 E21B34/04 F15B13/02 

FIELD: underwater hydrocarbon production.

SUBSTANCE: invention relates to a hydraulic plate for an underwater control unit, which is part of the control system equipment for a subsea hydrocarbon production system. The proposed hydraulic plate of the underwater control unit contains a housing having a base; an upper surface substantially parallel to the base; a side surface substantially perpendicular to the base. In this case, a plurality of combinations of holes are made in the housing, each of which contains a first hole for installing a quick-disconnect connection, a second hole for installing a throttle valve, a third hole for installing a pressure sensor, a group of four holes for installing a control valve. For each combination of holes, the location of the longitudinal axes of the first, second and third holes in a common plane is provided, which is also a cutting plane for the installed control valve.

EFFECT: invention reduces the size, as well as simplifies the assembly and disassembly of the structure of the hydraulic plate and access to its hydraulic components for adjusting them without the use of special tools.
