(EN) PACKER ELEMENT FOR USE IN A STUFFING BOX
(FR) ÉLÉMENT GARNITURE D'ÉTANCHÉITÉ À UTILISER DANS UN PRESSE-ÉTOUPE
Abstract
(EN)
The present invention regards a packer element (20) for use in a stuffing box (5) for sealing between to relative movable elements for instance a shaft (1) and house (2). The packer element (20) comprises an inner elastic material (21) comprising an inner void (23) and an outer abrasion layer (22). The inner void (23) is mostly fluid tight and comprises means providing at least one opening to the outside of the packer element (20), for pressurizing of the inner void (23). The invention also regards a method for producing the packer elements and method for installing it.
(FR)
La présente invention concerne un élément garniture d'étanchéité (20) à utiliser dans un presse-étoupe (5) afin d'appliquer une fermeture étanche entre deux éléments relativement amovibles, par exemple un arbre (1) et un logement (2). L'élément garniture d'étanchéité (20) comprend un matériau élastique interne (21) contenant une cavité interne (23) et une couche abrasive externe (22). La cavité interne (23) est surtout étanche au fluide et comprend des moyens dotés au moins d'une ouverture sur l'extérieur de l'élément garniture d'étanchéité (20) afin de mettre sous pression la cavité interne (23). L'invention a également trait à un procédé de production d'éléments garniture d'étanchéité et un procédé pour installer ces derniers.
