METHOD AND SYSTEM FOR TESTING VALVE DRIVE MECHANISM, AS WELL AS CORRESPONDING COMPUTER DEVICE Russian patent published in 2020 - IPC F16K37/00 F15B19/00

Abstract RU 2719266 C2

FIELD: machine building.

SUBSTANCE: method for testing a valve drive mechanism connected to a process control device, includes control stages by means of pressure process control device (804) in valve drive mechanism to change pressure from initial pressure value towards predetermined pressure limit, monitoring (806) position of the valve drive mechanism for detecting movement of the valve drive mechanism and when one of pressure values (810) in the valve drive reaches a predetermined pressure limit or detection (806) of movement of the pressure control valve driving mechanism (808) in the actuator valve mechanism to return to initial pressure.

EFFECT: invention discloses a method and a system for testing a valve actuator, as well as a corresponding computer device.
