Abstract:
Flow regulator, system and method that allow regulation of gas flow, both during a purging operation such as to purge a line of oxygen, and during a brazing operation to maintain the line free or substantially free of oxygen during the brazing operation. The system includes a gas source, such as a nitrogen tank containing a source of nitrogen, a gas regulator in fluid communication with the gas source to regulate the delivery pressure from the gas source, and a flow regulator in fluid communication with the gas source to regulate the flow of gas during the purge and brazing operations. The flow regulator provides a visual indication that gas is flowing, and a visual indication of the particular flow rate of the flowing gas.
