Abstract

Un sistema de empaque de dos piezas, de baja friccion de carga activa para seguridad de incendio y sellado de baja emision fugaz (menor de 500 partes por millon) de un vástago de válvula a temperatura de funcionamiento hasta de 232 degree C. Un juego de anillos de empaque inferior alrededor del vástago de válvula tiene arandelas de PTFE intercaladas entre los anillos de grafito flexibles para proporcionar seguridad de incendio y baja friccion. Un juego de anillos de empaque superior alrededor el vástago de válvula queda más proximo a la fuente de carga y tiene anillos de PTFE de tipo "V" para proporcionar sellado de baja emision fugaz y baja friccion confiables. La carga activa se lleva a lo optimo para mantener un sello en el juego de empaque superior hasta un escape menor de 500 partes por millon, para reducir al mínimo la friccion de empaque de ambos juegos de empaque superior e inferior y para sellar el juego de empaque superior e inferior y para sellar el juego de empaque inferior durante pruebas de seguridad de incendio.
