Abstract
(EN)
Provided is a safety valve. The safety valve, in one example, includes a piston located within a piston chamber, the piston separating the piston chamber into a first portion and a second portion and configured to slide to move a valve closure mechanism between a closed state and an open state. The safety valve, according to this example, includes a first control/balance line fluidically coupled to the first portion of the piston chamber, a second control/balance line fluidically coupled to the second portion of the piston chamber, and a chemical line fluidically coupled to the second control/balance line.

L'invention concerne une soupape de sûreté. Dans un exemple, cette soupape de sûreté comprend un piston situé à l'intérieur d'une chambre de piston, le piston séparant la chambre de piston en une première et une deuxième partie, et conçu pour coulisser afin de déplacer un mécanisme de fermeture de soupape entre un état fermé et un état ouvert. Dans cet exemple, la soupape de sûreté selon l'invention comprend une première ligne de commande/équilibrage couplée en communication de fluide à la première partie de la chambre de piston, une deuxième ligne de commande/d'équilibrage couplée en communication de fluide à la deuxième partie de la chambre de piston, ainsi qu'une ligne chimique couplée en communication de fluide à la deuxième ligne de commande/d'équilibrage.
