Title
(EN) CHOKE SYSTEM WITH CAPACITY FOR PASSAGE OF LARGE DEBRIS
(FR) SYSTÈME D'ÉTRANGLEMENT AVEC APTITUDE AU PASSAGE DE GROS DÉBRIS
Abstract
(EN) Embodiments include a choke system that passes enlarged debris despite having a relatively small diameter for an input port of the choke system. Embodiments also include systems to prevent dislodging of a choke seat when backpressure is supplied to the choke system. Embodiments also include sealing systems to prevent fluid leaks around the choke seat of the choke system.
(FR) Des modes de réalisation de l’invention concernent un système d'étranglement, lequel système permet de laisser passer des débris agrandis malgré le fait qu’il a un diamètre relativement petit pour un orifice d'entrée du système d'étranglement. Des modes de réalisation de l’invention concernent également des systèmes pour empêcher le délogement d'un siège d'étranglement quand une contre-pression est délivrée au système d'étranglement. Des modes de réalisation de l’invention concernent également des systèmes d'étanchéité pour empêcher des fuites de fluide autour du siège d'étranglement du système d'étranglement.
