Abstract

[0056] Un sistema neumático de cierre para una turbina que incluye una pieza de válvula; un vástago de válvula conectado a la pieza de la válvula; y un ensamblaje de actuador conectado al vástago de la válvula. El ensamblaje de actuador incluye un cilindro; un pistón conectado al vástago de la válvula, el pistón que divide el cilindro en una primera cámara y una segunda cámara; un elemento que desvía dispuesto en la segunda cámara del cilindro; un circuito neumático en comunicación con la segunda cámara del cilindro. El circuito neumático está configurado para presurizar la segunda cámara del cilindro para accionar el pistón para mover el vástago de la válvula y la pieza de la válvula a una posición de puesta en uso entre la posición abierta y la posición cerrada mientras que la primera cámara es presurizada.
