Title:
VALVE CONTROL DEVICE, VALVE CONTROL SYSTEM, METHOD FOR CALCULATING VALVE CONTROL COEFFICIENT, AND VALVE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2018/167994
Kind Code:
A1
Abstract:
Provided are: a valve control device which is capable of reducing the difference between a set opening amount and the actual opening amount, when executing a partial valve stroke test; a valve control system; a method for calculating a valve control coefficient; and a valve control method. This shut-off valve control device is provided with a microcomputer 7 for controlling the opening and closing of a solenoid valve 5 which supplies air from an air supply source 11, to a cylinder 31 of an air cylinder 3 for controlling a valve shaft 1b of a shut-off valve 1, and discharges said air. The microcomputer 7 acquires a set opening amount of the shut-off valve 1. Furthermore, the microcomputer 7 controls the solenoid valve 5 to a value obtained by dividing the acquired set opening amount by a predetermined coefficient C.
