AbstractAbstract
[en] A valve is introduced for application in a pipe in which a test probe is arranged. The valve serves to isolate the pipe in a gas-tight way, thus preventing the escape of radioactive gas or dust during operation in a nuclear reactor. (TK)

AbstractAbstract
[en] The valve possesses a conical chamber containing a ball, and a magnet is placed outside the chamber to attract the ball upwards and close the opening at the top of the chamber. When a probe is introduced it pushes the ball downwards and sideways towards the outside so that it can descend through the chamber. This system can be used for the closing of tubes, dry wells or containers when a detection probe is withdrawn, in a nuclear reactor vessel for example
[fr]
Le clapet comporte une chambre conique contenant une bille et un aimant a l'exterieur de la chambre pour attirer la bille vers le haut et fermer l'ouverture menagee au sommet de la chambre. L'introduction d'une sonde a pour effet de pousser la bille vers le bas et lateralement vers l'exterieur de maniere qu'elle puisse descendre a travers la chambre. Ceci est applicable a la fermeture de tubes, puits secs ou godets lors du retrait d'une sonde de detection, par exemple dans une enceinte de reacteur nucleaireOriginal Title
