Abstract

PURPOSE: To miniaturize a valve device by housing plates for vacuum cutting a plurality of openings into a housing section facing each other.
CONSTITUTION: An opening 2 of a device body 1 is divided into three subopenings 5aW5c equal in the area with two lateral frames mounted thereon and cutting plates 6aW6c are arranged for respective subopenings. Guide frames 7aW7c are formed longitudinally along both sides of the subopenings 5aW5c in such a manner that the cutting plates 6aW6c slides down to the lowest level to close the subopenings 5aW 5c. The side of the 6aW6c adhere to packings 8aW8c provided on the periphery of the subopenings 5aW5c to effect a vacuum cutting thereof. When no such a vacuum cutting is necessary, wires 9aW9c are wound with windlasses 10aW10c to pull the cutting plates into housing sections 11aW11c to store. As the housing sections 11aW11c are equal in the height, they are housed facing each other. Accordingly, the valve device only requires a housing area equivalent to about one-third of the total installation area in addition to the opening.
