Title
(EN) ELECTRONIC VALVE WITH DEFORMABLE SEAT AND METHOD
(FR) VALVE ÉLECTRONIQUE AYANT UN SIÈGE DÉFORMABLE ET PROCÉDÉ
Abstract
(EN)
An electronic valve (300) is placed in line with a casing (702) in a well (704). The electronic valve (300) includes a housing (301) having plural ports (314) that are blocked; a valve (360) configured to initiate unblocking of the plural ports (314) to allow fluid communication between the bore (304A) of the housing (301) and an outside of the housing (301); and a deformable seat device (330) having a body (332) placed inside of the bore (304A) of the housing (301). The deformable seat device (330) is configured to have a given diameter D3 for at least one of first and second ends (332A, 332B) of the body (332) when the plural ports (314) are blocked, and a smaller diameter when the plural ports (314) are unblocked.
(FR)
L'invention concerne une valve électronique (300) étant placée en ligne avec un carter (702) dans un puits (704). La valve électronique (300) comprend un boîtier (301) ayant plusieurs orifices (314) qui sont bloqués ; une valve (360) conçue pour déclencher le déblocage des multiples orifices (314) afin de permettre une communication fluidique entre le trou (304A) du boîtier (301) et un côté extérieur du boîtier (301) ; et un dispositif de siège déformable (330) ayant un corps (332) placé à l'intérieur du trou (304A) du boîtier (301). Le dispositif de siège déformable (330) est conçu pour avoir un diamètre D3 donné pour la première et/ou la seconde extrémité (332A, 332B) du corps (332) lorsque les multiples orifices (314) sont bloqués, et un diamètre plus petit lorsque les multiples orifices (314) sont débloqués.
