Abstract

UN SISTEMA DE REDUCCION DE LA PRESION DE UN FLUIDO QUE INCLUYE AL MENOS DOS CHORROS. UN CHORRO DE TRABAJO INCLUYE UNAS VALVULAS (19) Y (20) CON UNOS DETECTORES DE LA PRESION ASOCIADOS (22,23) PARA MODULAR LA PRESION DE SALIDA. UN SISTEMA DE CONTROL (50) CONTROLA LA PRESION A TRAVES DE UN DETECTOR (18) Y ACCIONA LA VALVULA DE CIERRE DE GOLPE (16) EN CASO DE QUE EXISTA UNA FALLA. EN CASO DE QUE EXISTA UNA FALLA EN EL OTRO CHORRO, LA DISPOSICION PERMITE QUE LA VALVULA DE CIERRE DE GOLPE (16) SE ABRA. SOLO EN EL CHORRO EN EL QUE EXISTE LA FALLA, LA PRESION VUELVE A SUBIR, Y LA VALVULA DE CIERRE DE GOLPE SE VUELVE A CERRAR Y NO SE PUEDE ABRIR DE NUEVO HASTA QUE SE VUELVA A PONER EN SU POSICION INICIAL MANUALMENTE UNA VEZ ARREGLADA LA FALLA. EL CONTROL INDEPENDIENTE DE CADA CHORRO AYUDA A MANTENER LA INTEGRIDAD DEL SISTEMA. TODOS LOS CHORROS SE PUEDEN CERRAR Y REABRIR UNA VEZ. EL SEGUNDO CIERRE DETERMINA EL CHORRO EN EL QUE EXISTE LA FALLA.
