PROBLEM TO BE SOLVED: To prevent water from reaching a compressor in a purging operation after a washing or rinsing operation of a gas turbine compressor. SOLUTION: A purge drain valve including a spool spliced in a fluid line includes a control valve and an actuator coupled to the control valve for regulating fluid flow. During a washing operation, fluid flows between a supply end and a delivery end of the spool, and during a purging operation, the control valve diverts fluid entering the supply end not to the delivery end but toward a drain leg. A washing system includes a fluid supply line and a delivery line, and a purge drain is spliced into the delivery line to permit fluid to flow into a washing apparatus during a washing operation and to prevent fluid from entering the washing apparatus during a purging operation. A rinse cycle sensor apparatus indicates to an operator if a washing operation is complete based upon a conductivity of the fluid exiting from a device being washed. COPYRIGHT: (C)2009,JPO&INPIT |
