GAS-PHASE HYDROGEN PERMEATION TEST DEVICE AND METHOD OF PROTECTING GAS-PHASE HYDROGEN PERMEATION TEST DEVICE

摘要

A hydrogen-based hydrogen permeability test apparatus capable of safely measuring hydrogen permeation behavior in a material under a high-pressure hydrogen atmosphere.A primary side discharge valve, a secondary discharge valve, a manual discharge means, a secondary side pressure regulator, a secondary side pressure regulator, a primary side discharge valve, a secondary side discharge valve, Closing valve and a control for bringing the primary side shutoff valve and the secondary side shutoff valve into a closed state when the pressure measured by the secondary side pressure gauge is equal to or greater than a predetermined value and opening the primary side discharge valve and the secondary side discharge valve Wherein the primary release valve, the primary discharge valve and the secondary discharge valve are air driven valves, and the manual discharge means is either or both of the safety valve and the rupture disc, the high pressure hydrogen supply means, A hydrogen-permeability test device with a pipe, a primary side shut-off valve, a primary release valve, a manual release means, a test piece, and a secondary release valve installed in an explosion-proof environment and an analyzer installed in a non-.
