SAFETY VALVE BYPASS ELEMENT GUARD FOR A BOILER SAFETY VALVE, CAPABLE OF CONTROLLING HIGH-PRESSURE HYDRAULIC FLUID TO REPLACE A SAFETY VALVE BYPASS ELEMENT IN A NORMAL OPERATION OF A GENERATING STATION

摘要

PURPOSE: A SBE(Safety valve Bypass Element) guard for a boiler safety valve is provided to carry out reliability inspection of an SBE during a normal operation of a generating station by selectively controlling high-pressure hydraulic fluid.;CONSTITUTION: A SBE guard for a boiler safety valve comprises a path opening/closing unit, and a supply pipe line, and a housing. The path opening/closing unit supplies and blocks high pressure hydraulic fluid to an SBE(120). The supply pipe line is connected between the actuator and the SBE and supplies the hydraulic fluid from an actuator to the SBE. The housing is integrally formed with the path opening/closing unit.;COPYRIGHT KIPO 2010
