SUBMERSIBLE PUMP VALVE DEVICE Russian patent published in 2024 - IPC F04D13/10 E21B34/06 F04B53/10 F16K15/00 

FIELD: oil industry.

SUBSTANCE: invention relates to oil industry and can be used in borehole pump units to control fluid flow. Submersible pump valve device, including housing, main ball valve with seat, switching device with actuator and shutoff element located below rotary under action of actuator with channels communicating in series through lower bypass channel in housing space below shut-off element with space above main ball valve through upper bypass channel of housing. Rotary shut-off element is made in the form of a drum with an upward projecting axis and at least three longitudinal through channels, in one of which the main valve with a seat is located, the other one is left free, and the rest are equipped with additional valves with corresponding seats. Switching device is used in the form of a stepper motor with a control cable, and the actuating mechanism is in the form of a gearing connecting the axis of the rotor of the motor to the axis of the drum for its rotation under the action of the motor with serial alignment of channels with bypass channels of the housing.

EFFECT: simplification of the design and, as a result, reduction of its metal consumption by reducing the number of parts, increasing the overhaul period due to the use of a fixed valve seat and at least one additional valve, which duplicates the operation of the main one, and expansion of functional capabilities due to possibility of downhole equipment flushing with direct flow of liquid.
