Abstract:
PROBLEM TO BE SOLVED: To provide an emergency air supply system capable of automatically supplying driving air, and capable of maintaining a state in which an air-operated valve can be operated even when an air source is lost in a plant.SOLUTION: An emergency air supply system 10 includes an air-operated valve 101, a check valve 102 installed in air piping 202 between the air-operated valve 101 and an air source 201 and inhibiting driving air from flowing back toward the air source 201, earthquake-proof air piping 103 which is a part of the air piping 202 and connects the air-operated valve 101 with the check valve 102 and has prescribed earthquake-resistance strength, an emergency air storage tank 104, emergency air piping 105, and an attachment 106 provided in the emergency air piping 105 and closing a pipeline of the emergency air piping 105. The attachment 106 opens the pipeline of the emergency air piping 105 when a pressure of the driving air in the earthquake-proof air piping 103 side is smaller than a pressure of the driving air in the emergency air storage tank 104 side by a prescribed value or more.
