<p>Disclosed is a pressure control device for a large flow regulator. The disclosed large flow regulator comprises a receiver tank, which provides pressure to the large flow regulator by being connected to the large flow regulator; a pressure detecting sensor, which is arranged between the receiver tank and the large flow regulator and detects the value of the pressure flowing to the large flow regulator from the receiver; a pressurizing solenoid valve, which controls the pressure flowing into the receiver tank to be a specified pressure by selectively pressurizing the pressure flowing to the receiver tank; and a control unit. The control unit operates the pressurizing solenoid valve when the pressure value detected by the pressure detecting sensor is lower than a predetermined pressure by being electrically connected to the pressure detecting sensor and the pressurizing solenoid valve, thereby increasing the pressure value to be a predetermined pressure value. When the pressure value detected by the pressure detecting sensor is higher than the predetermined pressure value, the control unit lowers the pressure value to be the predetermined pressure value by operating the solenoid valve.</p> |
