Claims

[Claims for Utility Model Registration] A ballast valve that supplies and drains water to a ballast tank that adjusts the inclination of the ship, and a first pressure chamber and a second pressure chamber, and these pressure chambers are supplied and exhausted to open and close the ballast valve. an actuator, a first supply/discharge port connected to a first pressure chamber of the actuator via a first pipe, a second supply/discharge port connected to a second pressure chamber of the actuator via a second pipe, and a pressurized air supply/discharge port. a supply port connected to a source, and a discharge port;
an operating valve that switches the supply/discharge path to the actuator; a limit valve that detects opening/closing of the ballast valve and sends out pressurized air; and a first valve that indicates whether the ballast valve is open based on the pressurized air from the limit valve. an indicator, and a second indicator that indicates the closing of the ballast valve based on the pressure air from the limit valve, the ballast valve;
A ballast valve opening/closing device in which an actuator and a limit valve are disposed in or near a ballast tank, and the operation valve, a first indicator, and a second indicator are disposed away from the ballast tank, The valve has a first inflow port connected to the first pressure chamber of the actuator, a second inflow port connected to the second pressure chamber of the actuator, and an outflow port, and the valve has a first inflow port connected to the first pressure chamber of the actuator, a second inflow port connected to the second pressure chamber of the actuator, and an outflow port. Either the first inflow port or the second inflow port is connected to the outflow port, a third pipe is connected to the outflow port of the limit valve, and the third pipe is guided to the vicinity of the operation valve. 3
A first indicator indicates the opening of the ballast valve by the pressure air in the pipe and the first pipe, and a second indicator indicates the ballast valve is closed by the pressure air in the third pipe and the second pipe. A ballast valve opening/closing device configured to display.
