The present invention relates to a fluid sealing storage bag, and provides a fluid sealing storage bag in which a blocking member capable of preventing a gas component from being exposed to the outside is mounted at one end of a discharge valve, which is coupled to a storage bag main body so as to be sealed, thereby preventing the gas component of a solution stored in the storage bag main body from being exposed to the outside when the discharge valve is in a closed state, and thus a change in characteristics such as a change in the concentration and the components of the solution stored in the storage bag main body is prevented so as to improve the accuracy and confidence of a test result when performing various tests by using the same, and the blocking member is opened by the penetration of a valve spool when the discharge valve is operated to be open, thereby completely performing the function of blocking the leakage of the gas component during a closing operation and allowing the solution of the storage bag main body to flow smoothly, through the penetration region of the blocking member, into a valve main body so as to be discharged to the outside during an opening operation.La présente invention concerne un sac de stockage étanche au fluide, et utilise un sac de stockage étanche au fluide dans lequel un élément de blocage, pouvant empêcher un composant gazeux dêtre exposé à lextérieur, est monté au niveau dune extrémité dune soupape dévacuation, qui est accouplée à un corps principal du sac de stockage de manière à être hermétiquement scellée, ce qui empêche le composant gazeux dune solution stockée dans le corps principal du sac de stockage dêtre exposé à lextérieur lorsque la valve dévacuation est à létat fermé, et on évite ainsi une modification des caractéristiques telles quune modification de la concentration et des composants de la solution stockée dans le corps principal du sac de stockage, ce qui améliore la précision et la garantie dun résultat de tes
