Abstract

UN MONTAJE DE VALVULA PARA PROVEER VARIAS DILUCIONES DE UNA MUESTRA DE LIQUIDO SIMPLE, Y QUE COMPRENDE UN PAR DE ELEMENTOS ESTACIONARIOS EXTERNOS (24,28) QUE EMPAREDAN A UN ELEMENTO GIRABLE (26) QUE LLEVA PASOS SEGMENTADORES DE VOLUMEN PRECISO (52,54,96). UN ELEMENTO EXTERNO LLEVA CIRCUITOS (46,48,50), CADA UNO PARA MEDIR Y ALMACENAR VOLUMENES PRECISOS DE DILUYENTE. UN CUERPO CONTINUO DE MEZCLA ES INTRODUCIDO DENTRO DE LA VALVULA A LO LARGO DE UN PASO A TRAVES DE UN PAR (52,54) DE PASOS SEGMENTADORES Y UN PAR DE PARTES (ALICUOTAS) MEDIDAS QUE SON AISLADAS DE DICHO PASO. EL ELEMENTO (26) ES OPERADO PARA DIRIGIR UN ALICUOTA A LO LARGO CON EL CONTENIDO DE UN CIRCUITO (46) A UN LUGAR EXTERIOR (12) PARA FORMAR UNA PRIMERA DILUCION. LA OTRA MUESTRA ALICUOTA ES RETENIDA. LA PRIMERA DILUCION ES INTRODUCIDA DENTRO DE LA VALVULA A LO LARGO DE UN PASO A TRAVES DEL TERCER PASO SEGMENTARIO (96) Y SU ALICUOTA ES AISLADO. AMBOS SON DIRIGIDOS DESDE LA VALVULA A LUGARES TESTADORES RESPECTIVOS (14,16) A LO LARGO CON EL CONTENIDO RESPECTIVO DE LOS CIRCUITOS REMANENTES (48,50). LOS CANALES (140,95) ESTAN PROVISTOS EN LAS CARAS INTERIORES DEL ELEMENTO EXTERNO (24,28) Y COMUNICATIVAMENTE ACOPLADO. LAS PUERTAS DE ENTRADA (130) Y SALIODA (82) PERMITEN LIMPIAR LOS REACTIVOS QUE SE VAN A INTRODUCIR EN EL, EL ELEMENTO EMPAREDADO (26) QUE GIRA 360 GRADOS POR LO CUAL ACLARAR LA SUPERFICIE INTERIOR DE LA VALVULA.
