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

摘要

Provided is a gas-phase hydrogen permeation test device capable of safely measuring hydrogen permeation behavior in a material under a high-pressure hydrogen atmosphere. The gas-phase hydrogen permeation test device includes a high-pressure hydrogen feeder, an analyzer, a primary-side pipe, a secondary-side pipe, a secondary-side pressure gauge, a primary-side shut-off valve, a primary-side discharge valve, a secondary-side discharge valve, a passive discharger, a secondary-side shut-off valve, and a controller configured to, when the pressure measured by the secondary-side pressure gauge reaches or exceeds a specific value, place the primary-side shut-off valve and the secondary-side shut-off valve into a closed state and the primary-side discharge valve and the secondary-side discharge valve into an open state, in which the primary-side shut-off valve, the primary-side discharge valve, and the secondary-side discharge valve are air-operated valves, the passive discharger is either or both of a safety valve and a rupture disk, the high-pressure hydrogen feeder, the primary-side pipe, the primary-side shut-off valve, the primary-side discharge valve, the passive discharger, the test piece, and the secondary-side discharge valve are installed in an explosion-proof environment, and the analyzer is installed in a non-explosion-proof environment.
