Title (EN) VALVE SYSTEM HAVING A SOFT LANDING PLUG
(FR) SYSTÈME DE SOUPAPE AYANT UN BOUCHON DE POSE SOUPLE
Abstract:
(EN) A choke valve system includes a choke valve (14) having a body (20) and an annular seat (34) disposed within the body. The choke valve also includes a plug (30) configured to move relative to the annular seat between an open position (46) in which a fluid is enabled to flow through the choke valve and a closed position (100) in which the fluid is blocked from flowing through the choke valve and in which the plug contacts an annular seating surface of the annular seat. The choke valve further includes a damper (32) coupled to the plug, and the damper is configured to absorb a load generated by contact between the plug and the annular seating surface of the annular seat as the plug moves into the closed position.
(FR) L'invention concerne un système de duse de soupape, qui comprend une duse de soupape (14) ayant un corps (20) et un siège annulaire (34) disposé à l'intérieur du corps. La duse de soupape comprend également un bouchon (30) conçu pour se déplacer par rapport au siège annulaire entre une position ouverte (46), dans laquelle un fluide est autorisé à s'écouler à travers la duse de soupape, et une position fermée (100) dans laquelle le fluide est empêché de s'écouler à travers la duse de soupape, et dans laquelle le bouchon est en contact avec une surface d'appui annulaire du siège annulaire. La duse de soupape comprend en outre un amortisseur (32) accouplé au bouchon, et l'amortisseur est conçu pour absorber une charge générée par contact entre le bouchon et la surface d'appui annulaire du siège annulaire à mesure que le bouchon se déplace dans la position fermée.
