Abstract

PURPOSE: To enable to surely shutdown a flow conduit even in the event of an electric system trouble by enabling to cancel the stopper working either through a solenoid or a pressure sustaining member.
CONSTITUTION: An emergency shutdown valve is displaced accompanying a transport fluid dynamic pressure change and also is provided with a pressure sustaining member 13 mechanically interlocked with a stopper 11 and a solenoid 14 interlocked with the stopper 11. Since said constitution enables it to do the function cancelling operation of the stopper 11 through the solenoid 14, it is possible to shutdown the flow conduit R and to check the fluid flowing-out to the minimum by closing the valve before the breaking of the tube 1 accompanying an extraordinary state generation or before losing a large quantity of fluid after damage by operating the solenoid 14 in connection with a vibrometer. Moreover, even in the event of the electric system breakdown on account of the transport fluid dynamic pressure displacement accompanying the damaged tube 1 the pressure sustaining member 13 can operate to cancel the function of the stopper 11.
