Abstract

UN MONTAJE DE MEDICION DE LIQUIDOS Y DE VALVULAS DE TRANSFERENCIA (10) PARA UN SISTEMA DILUIDOR QUE CONSTA DE UN PAR DE ELEMENTOS DE DISCOS DE VALVULA EXTERIORES FIJOS (12, 16) QUE INTERCALAN UN ELEMENTO DE DISCO DE VALVULA QUE PUEDE GIRAR CENTRAL (14). LOS ELEMENTOS (12, 14, 16) ESTAN ALINEADOS COAXIALMENTE Y MONTADOS SOBRE UN VASTAGO (24). UNO (16) DE LOS ELEMENTOS EXTERIORES (12, 16) TIENE UN PRIMER BUCLE EXTERNO (28) ASEGURADO AL MISMO, EL CUAL TIENE UN VOLUMEN INTERIOR PRECISO. HAY UNA SONDA ASPIRADORA (26) ASEGURADA AL ELEMENTO CENTRAL (14). EL ELEMENTO CENTRAL (14) TIENE UN PASAJE DE SEGMENTACION AXIAL (72) QUE TIENE UN VOLUMEN INTERIOR PRECISO. HAY UN SEGUNDO BUCLE EXTERNO (86) ASEGURADO AL ELEMENTO CENTRAL (14). EL SEGUNDO BUCLE (86) SE EXTIENDE HACIA AFUERA, PREFERIBLEMENTE RADIALMENTE, DE DICHO ELEMENTO (14) Y TIENE UN VOLUMEN INTERNO PRECISO. SE PROPORCIONAN UNOS PASAJES (36, 54, 56, 30) INTERIORES APROPIADOS EN LOS ELEMENTOS EXTERIORES (12, 16) PARA DIRIGIR UNA MUESTRA DE LIQUIDO SIGUIENDO UNA TRAYECTORIA CONTINUA A TRAVES DEL MONTAJE DE LA VALVULA, CUYA TRAYECTORIA INCLUYE EL PASAJE DE SEGMENTACION (72) Y LOS BUCLES PRIMERO Y SEGUNDO (28, 86). HAY UNOS PASAJES INTERIORES ADICIONALES (58, 34, 62, 76, 74, 82, 84) PARA ACOPLAR EL MONTAJE DE LA VALVULA A LAS FUENTES DE DILUYENTE P2 Y A LOS DESTINOS EXTERIORES. SE HACE GIRAR AL ELEMENTO CENTRAL (14) PARA AISLAR LOS CONTENIDOS DEL PASAJE DE SEGMENTACION (72) Y DE LOS BUCLES PRIMERO Y SEGUNDO (28, 86) Y SE INTRODUCE DILUYENTE EN EL MISMO PARA LLEVAR LOS CONTENIDOS AISLADOS DEL MISMO A DICHOS DESTINOS. SOLO SE NECESITA UN PASO DE CARGA PARA OBTENER LOS TRES VOLUMENES PRECISOS DE LA MUESTRA DE LIQUIDO. EL MONTAJE DE LA VALVULA SE PUEDE ENJUAGAR Y HAY UNOS CANALES INTERNOS CONTINUOS (102, 104) PARA EVITAR QUE CUALQUIER LIQUIDO ALCANCE LAS SUPERFICIES CIRCUNFERENCIALES 12'''''', 14'''''', 16'''''' DEL MONTAJE DE LA VALVULA.
