CHECK VALVE Russian patent published in 2025 - IPC F16K15/02 F16K15/12 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to check valves and can be used in power engineering. Check valve comprises a body with a seat, covers with inlet and outlet branch pipes, a flat resilient element, a shut-off element. In the valve body, a support is installed by means of a threaded connection, made in the form of a cross, with the possibility of axial movement when setting the opening pressure, having an annular groove on one side, and the flat elastic element is a flat membrane with open slots and a centre hole interacting with the cylindrical protrusion of the shut-off element in the form of a plate, and the cross-hair of the support is a limitation of the plate travel.
