Abstract
PURPOSE: To precisely display the opening and closing action of a valve while accurately grasping the quantity of state of valve opening, by mounting a device for detecting the valve opening and annunciators that their display conditions change in response to the detecting value.
CONSTITUTION: The following devices are installed; a device 11 for detecting vlave opening, red and green annunciators RL, GL that their display conditions alter in response to the detecting value. When a valve moves to totally-enclosing from totally-opening, the device 11 for detecting valve opening shifts in the arrow head direction, the sliding resistance of terminals 11aW11b increases, the sliding resist ance of terminals 11aW11c decreases, the brightness of the red annunciator RL slowly diminishes and the brightness of the green annunciator GL gradually augments. Thus, the condition of the opening and closing action of the valve can precisely be displayed, and the quantity of state of the valve opening can accurately be grasped.
