METHOD FOR TESTING THE SOLENOID VALVE AND THE CORRESPONDING DEVICE (VERSIONS) Russian patent published in 2021 - IPC F15B19/00 F16K37/00 

FIELD: solenoid valves.

SUBSTANCE: proposed method for testing a solenoid valve includes starting a pulse period and an observation period for testing a solenoid valve by executing the first commands through the processor. Giving a command to the solenoid valve by executing second commands by the processor to transition from the first state to the second state during the pulse period, and the solenoid valve has a hydraulic connection with the actuator allowing the actuator to activate the emergency valve. Determining the functionality of the solenoid valve through the execution of third commands by the processor by measuring the maximum pressure change in the pressure chamber of the actuator by means of the valve positioner during the observation period. After determining the functional state of the solenoid valve, by executing the fourth commands through the processor, testing the emergency valve with a partial stroke by means of the valve positioner. Also, versions of devices for testing the solenoid valve are proposed.

EFFECT: improving the reliability of the solenoid valve.
