Abstract

Organe de fermeture pour tuyau ou enceinte sous pression. Un organe de fermeture selon l'invention comprend un opercule à emboîter dans une ouverture du tuyau ou de l'enceinte sous pression et un mécanisme de verrouillage destiné à verrouiller l'opercule sur le tuyau ou l'enceinte sous pression. Le mécanisme de verrouillage comprend un pêne annulaire 14 disposé sur le pourtour de l'opercule 6 et dont on peut rapprocher ou écarter l'une de l'autre les extrémités 17, 18 pour provoquer l'expansion ou la rétraction radiale du pêne 14, ce qui fait prendre ou quitter à celui-ci la position de verrouillage dans laquelle il porte contre le tuyau ou l'enceinte sous pression 1. Application, entre autres, à la fermeture de trous d'accès ayant des dimensions relativement faibles.
