CONNECTION APPARATUS FOR PRESSURE TESTING OF SAFETY VALVE AND TESTER SAFETY VALVE OF GENERATING FACILITIES USING THE CONNECTION APPARATUS

摘要

A connection apparatus for testing the pressure of a safety valve and a safety valve tester for power generation equipment using the connection apparatus are provided to reduce the manufacturing cost by using only discs having different diameters. A connection apparatus includes a connection flange(1), a plurality of discs(2), and a plurality of bolts. The connection flange includes a peripheral protrusion having four assembling holes(111). The connection flange includes a vertical fluid passing hole connected to a test fluid supply pipe through a connection unit. The fluid passing hole is formed at a central portion of the disc. The discs are selectively installed according to the outer diameters of circumferential adhesion surfaces of nozzles to close spaces between the connection flange and the circumferential adhesion surfaces of the nozzles. The bolts connect the connection flange and a protruding flange.
