Abstract

Una válvula con un montaje de empaquetadura incluye un montaje de cuerpo de válvula (12) con una perforación, un elemento de válvula (17) movible entre una posición abierta y una posición cerrada, y un vástago de válvula (23) acopIado al elemento de válvula; una primera empaquetadura de vástago (37) circunscribe una parte del vástago de válvula, y se ubica en una parte de perforación superior de la perforación; un primer retén de empaquetadura (41) tiene un collar que limita el movimiento axial de la primera empaquetadura de vástago, y también tiene un primer cuerpo de retención que define una cavidad interior; una segunda empaquetadura de vástago (57) circunscribe una parte del vástago de válvula y se ubica en la cavidad interior del primer retén de empaquetadura; un segundo retén de empaquetadura (67) tiene un cuello que conecta compresivamente la segunda empaquetadura de vástago, y un hombro de retención que conecta al primer retén de empaquetadura; un montaje de retención (84) se acopla con el montaje de cuerpo de válvula para aplicar una fuerza axial al segundo retén de empaquetadura.
