Abstract

L'invention concerne un dispositif de verrouillage des couvercles des récipients mis sous pression. Le dispositif comporte une barre de verrouillage 6 reposant sur deux berceaux 7 et 8 soudés au récipient 1, une ferrure 9 servant à articuler une extrémité de la barre 6 au berceau 7 et un vérin pneumatique 10 reliant l'autre extrémité de la barre au récipient, le fonctionnement de ce vérin 10 étant commandé par la pression interne audit récipient si bien que le déverrouillage s'avère impossible tant qu'une mise à l'air libre préalable n'a pas été effectuée. Application aux récipients mis sous pression, notamment aux récipients de transport de produits pulvérulents ou granuleux.
