The present invention features installation system (10) for facilitating the installation and removal of a closure onto and from pressure vessel (22), respectively. Installation system (10) comprises fixed support structure (40) constructed proximate pressure vessel (22); valve carriage (60) dynamically and continuously supported by fixed support structure (40), wherein valve carriage (60) also dynamically and adjustably supports a closure, such as a header or deheader valve (14), in a continuous manner; elevation adjustment assembly (90) allowing valve carriage (60) and the closure to move in a vertical manner relative to fixed support structure (40) and pressure vessel (22); and horizontal transfer assembly (110) that dynamically couples the closure to valve carriage (60) to enable horizontal, bi-directional transitioning of the closure relative to valve carriage (60). Elevation adjustment assembly (90) and, horizontal transfer assembly (110) work in harmony together to provide both approximate and precision vector positioning of the closure to enable parallel and concentric alignment with pressure vessel (22). In this manner, the closure may be installed and removed from pressure vessel (22) in a much safer and more efficient manner.

L'invention concerne un système d'installation (10) destiné à faciliter l'installation et l'enlèvement d'une fermeture d'un récipient à pression (22). Le système d'installation (10) comprend une structure support fixe (40) construite à proximité du récipient à pression (22); un porte-soupapes (60) s'appuyant dynamiquement et continuellement sur la structure support fixe (40). Ledit porte-soupapes (60) supporte également de manière dynamique et réglable une fermeture, par exemple une soupape de fermeture ou d'ouverture (14) d'une manière continue; un ensemble réglage d'élévation (90) qui permet au porte-soupapes (60) et à la fermeture de se déplacer verticalement par rapport à la structure support fixe (40) et au récipient à pression (22); et un ensemble transfert horizontal (110) qui raccorde de manière dynamique la fermeture au porte-soupapes (60) de façon à permettre la transition horizontale, bidirectionnelle de la fermeture par rapport au porte-soupapes (60). L'ensemble réglage d'élévation (90) et l'ensemble transfert horizontal (110) collaborent harmonieusement et produisent un positionnement vectoriel à la fois approximatif et de précision de la fermeture afin de permettre un alignement parallèle et concentrique avec le récipient à pression (22). Ainsi, la fermeture peut être installée sur le récipient à pression (22) et enlevée de ce dernier d'une manière beaucoup plus sûre et plus efficace.
