Title: APPARATUS AND METHOD FOR PRESSURE RESISTANCE TEST FOR VALVE, AND HYDROGEN GAS-DETECTION UNIT
Abstract:
Provided are: an apparatus and a method for a pressure resistance test for a valve; and a hydrogen gas-detection unit, wherein even for valves having different sizes and shapes, a simple configuration can be used to rapidly and accurately perform a pressure resistance test while preventing errors in the test results, and detect and specify the location of external leaks, post-treatment for the valves is not necessary, and mass processing is possible through automation. This apparatus comprises: a cover 2 in which a test valve 1 is accommodated so as to be isolated from the outside; and a sensor 22 which is disposed inside the cover 2 and can be moved to a position close to the outer surface of the test valve 1 in which a search gas is sealed, wherein the sensor 22 is a gas sensor capable of detecting the external leakage of the search gas from the test valve 1.
