Abstract
(EN)
Provided is a search gas mixing method with which a diffusive gas and an inert gas are mixed in a short time by small and simplified equipment to safely produce a search gas for leakage inspection is safely generated, so that the inspection of leakage from a pressure apparatus can be simply and efficiently performed. A search gas composed of a diffusive gas and an inert gas is used, one of the gases is sealed in a sample 1 with a pressure corresponding to a predetermined concentration, and then, the other of the gases raises the pressure inside the sample 1 up to an inspection pressure. Thus, the inspection of leakage from the pressure apparatus is performed with the search gas having the predetermined concentration.

L'invention concerne un procédé de mélange de gaz de recherche grâce auquel un gaz de diffusion et un gaz inerte sont mélangés en un temps court par un équipement réduit et simplifié afin de produire en toute sécurité un gaz de recherche destiné à une inspection de fuite généré en toute sécurité, de telle sorte que l'inspection de fuite depuis un appareil de pression puisse être effectuée de manière simple et efficace. Un gaz de recherche composé d'un gaz de diffusion et d'un gaz inerte est utilisé, l'un des gaz est enfermé hermétiquement dans un échantillon (1) avec une pression correspondant à une concentration prédéterminée, puis l'autre gaz augmente la pression à l'intérieur de l'échantillon (1) jusqu'à une pression d'inspection. Ainsi, l'inspection de fuite depuis l'appareil de pression est effectuée avec le gaz de recherche présentant la concentration prédéterminée.
