Abstract

PURPOSE: To avoid impact upon the opening and closing of a valve with a valve box transferred by an electric driving system for converting the rotation of a motor into reciprocation.
CONSTITUTION: When voltage is impressed to a DC motor 101, generated rotational force axially slides a driving ring 107 using a driving shaft 103, a flat gear portion 108b and a female thread portion 107a. When the ring 107 slides in direction A, an operating ring 40 slides in direction A counter to the force of a spring 43. This motion transfers a valve box 21 using a movable disc 31 and an insulating connecting member 26. Thereby, a clearance through which liquid flows is caused between a valve portion 3 and a valve seat 25. A driving ring 107 slides in counter- A direction to initial position through the change-over of impression voltage. Since the ring 40 is outside, change-over can be made to manual operation if any trouble has occurred to a driving system.
