Abstract

UNA VALVULA (18) DE CONTROL PRINCIPAL CONTROLADA MEDIANTE PRESION DIVIDE EL LIQUIDO ENTRE UN ORGANO (12) DE AJUSTE HIDRAULICO, UNA BOMBA (20) Y UN RECIPIENTE (22) DE RESERVA. ENTRE CADA CONEXION (26,28) DE TRABAJO DE LA VALVULA (18) DE CONTROL PRINCIPAL Y UNA CONEXION (14,16) DEL ORGANO DE AJUSTE PERTENECIENTE SE DISPONE DE UNA VALVULA (44,46) DE EXCLUSION, EVITANDO LA FUGA DEL LIQUIDO DE LAS CONEXION (14,16) DEL ORGANO DE AJUSTE. CADA VALVULA (44,46) DE EXCLUSION CONTIENE UNA PARTE (56) DE VALVULA DE ASIENTO INFLUENCIABLE MEDIANTE PRESION, QUE ESTA EXPUESTA A LA PRESION DEL FLUIDO EN UNA CAMARA (50) DE EXCLUSION. ENTRE CADA VALVULA (44,46) DE EXCLUSION O BLOQUEO Y UNA VALVULA (40,42) DE CONTROL PERTENECIENTE, SE HA DISPUESTO DE UNA VALVULA (60,62) DE CONTROL DE SALIDA. CADA VALVULA (60,62) DE CONTROL DE SALDA CONTIENE UNA VALVULA (66) DE RETENCION DE SALIDA, QUE CONTROLA EL LIQUIDO DE PURGA A PARTIR DE LA CAMARA (50) DE BLOQUEO, ASI COMO UN EMBOLO (68) DE VALVULA DE SALIDA, QUE PRESIONA ATRAVES DE UN MEDIO (72) ELASTICO EN UNA POSICION, EN LA QUE LA VALVULA (66) DE RETENCION DE SALIDA SE ESTRECHA EN SU POSICION CERRADA, DE FORMA QUE EL LIQUIDO NO PUEDE EVADIRSE A PARTIR DE LA CAMARA (50) DE BLOQUEO. SON ACEPTADAS AMBAS VALVULAS (40,42) DE CONTROL, DE FORMA QUE CONTROLAN UNA VALVULA (100) LOGICA EN UNA VALVULA (80) DE FLOTACION QUE SE TRANSMITE A UNA POSICION DE FLOTACION, EN DONDE AMBAS CONEXIONES (26,28) DE TRABAJO DE LA VALVULA (18) DE CONTROL PRINCIPAL ESTAN UNIDAS A TRAVES DE LAS VALVULAS (44,46) DE BLOQUEO Y DE LA VALVULA (80) DE FLOTACION DE FORMA CONJUNTA Y CON EL RECIPIENTE (22) DE RESERVA. LA FUNCION DE FLOTACION ES REALIZABLE SIN VALVULA MAGNETICA ADICIONAL Y SIN MENOSCABO DE LAS ZONAS DE MODULACION DE LA VALVULA (18) DE CONTROL PRINCIPAL.
