Abstract
PURPOSE: To prevent the dangerousness of wrong operation of a valve, by switching a fluid, which opens or closes a valve element through mechanical interlocking with the section of the drive shaft of a driver and by dispensing with electric control.
CONSTITUTION: To close a gate valve, an electromagnetic change-over valve 16 is energized so that compressed air is introduced into the tube 5 of an air cylinder 3, a piston 4 is pressurized and a valve element 1 is moved leftward. At that time, a stopper 20 collides against a lug 25 so that the motion of the valve element 1 is stopped. Howerver, the pressurization of the piston 4 is continued to move a piston shaft 27 leftward. When an operating member 31 pushes the lever 30 of a mechanical change-over valve 29, compressed air is injected into an air chamber 11 so that a valve seat 8 coupled with bellows 6, 7 is moved and thrusted on the valve element 1 to perform hermetic sealing. This results in preventing the dangerousness of wrong operation of the valve.
