Abstract

SISTEMA DE OBTURACION DE CARGA DINAMICA, DE DOS PARTES Y BAJA FRICCION, PARA LA PROTECCION CONTRA EL FUEGO Y SELLADO DE EMISIONES DE ESCAPE BAJAS (MENOS DE 500 PPM) DE LA CAÑA DE UNA VALVULA, QUE FUNCIONA A TEMPERATURAS DE HASTA 450 F (232 (GRADOS) C). UN CONJUNTO DE ANILLOS DE OBTURACION INFERIOR, ALREDEDOR DE LA VALVULA, TIENE ARANDELAS PTFE ENTRE ANILLOS DE GRAFITO FLEXIBLES, PARA PROPORCIONAR PROTECCION CONTRA EL FUEGO Y BAJA FRICCION. UN CONJUNTO SUPERIOR DE ANILLOS OBTURADORES ALREDEDOR DE LA CAÑA DE LA VALVULA ESTA MAS CERCA DE LA FUENTE DE CARGA Y TIENE ANILLOS PTFE DEL TIPO-V, QUE PROPORCIONAN UN SELLADO FIRME DE EMISIONES BAJAS DE ESCAPE Y BAJA FRICCION. LA CARGA DINAMICA SE OPTIMIZA PARA MANTENER UN SELLO EN EL CONJUNTO OBTURADOR SUPERIOR A UN ESCAPE DE MENOS DE 500 PPM, MINIMIZAR LA FRICCION DE OBTURACION TANTO DEL CONJUNTO OBTURADOR SUPERIOR, COMO DEL INFERIOR Y SELLAR EL CONJUNTO DE OBTURACION INFERIOR DURANTE LAS PRUEBAS DE PROTECCION CONTRA INCENDIOS.
