Abstract
PURPOSE: To accurately detect the trouble of a valve without adding complicated equipment, by comparing the actual opening and closing period of the valve with a stored one to judge whether the opening and closing action of the valve is right or wrong.
CONSTITUTION: Valve opening and closing period signals from a controller 10, which regulates the opening and closing of a suction control valve 4 and a wind release valve 5, are applied to a monitor 11 to compare the actual opening and closing periods of the valves 4, 5 with stored ones to judge whether the opening and closing action of the valves 4, 5 is right or wrong. The trouble of the valves 4, 5 can thus be accurately detected without adding complicated equipment.
