Title
(EN) PERIMETER SEATED KNIFE GATE VALVE
(FR) ROBINET-VANNE À GUILLOTINE À SIÈGE PÉRIMÉTRIQUE
Abstract
(EN) Technologies are generally described for perimeter seated knife gate valve. Perimeter and transverse seals may be formed together as a single-piece or as two separate pieces. Wire-reinforced and with a rectangular cross section, the perimeter seal (portion) may fit into a corresponding groove in the single-piece body of the valve. Transverse seal (portion) may include two channels formed as side grooves or tubular channels to accept packing material, which energize the seal and are isolated from the fluid stream. In the two-piece version, a bottom groove of the transverse seal may be used to interlock both pieces. The shape and structure of the seal may allow single-piece valve body.
(FR) La présente invention concerne d'une manière générale des technologies pour un robinet-vanne à guillotine à siège périmétrique. Des joints d'étanchéité périmétriques et transversaux peuvent être formés ensemble sous la forme d'une seule pièce ou de deux pièces séparées. Doté d'une armature métallique et ayant une section transversale rectangulaire, le joint d'étanchéité périmétrique (partie) peut s'insérer dans une rainure correspondante dans le corps monopièce de la vanne. Un joint d'étanchéité transversal (partie) peut comprendre deux canaux formés sous la forme de rainures latérales ou de canaux tubulaires pour accepter un matériau de garniture, qui excitent le joint d'étanchéité et sont isolés du flux de fluide. Dans la version en deux pièces, une rainure inférieure du joint d'étanchéité transversal peut être utilisée pour verrouiller les deux pièces. La forme et la structure du joint d'étanchéité peuvent permettre un corps de vanne monopièce.
