Abstract
UNA VALVULA REGULADORA DE ALTA PRESION (2), UTILIZADA EN LA CROMATOGRAFIA, SIRVE COMO VALVULA REGULADORA DE CONTRAPRESION, LA CUAL DEBE MANTENER UNA DETERMINADA PRESION PREFIJADA EN UN PILAR DE SEPARACION . LA VALVULA TIENE UN ASIENTO (12) EN CUYO CENTRO SE ENCUENTRA UNA ABERTURA (18) PARA EL CONDUCTO DE SALIDA, Y UN CUERPO DE VALVULA (13) QUE COOPERA CON EL ASIENTO. EL CUERPO DE LA VALVULA (13) ES REGULABLE ACTIVAMENTE EN EL SENTIDO DE LA ABERTURA CON LA AYUDA DE UN CONVERTIDOR PIEZO; EN EL SENTIDO DE CIERRE, ES CONTROLADO ACTIVAMENTE. LOS LADOS ENCARADOS DEL ASIENTO (12) Y DEL CUERPO (13) ESTAN CONFIGURADOS DE MODO QUE, PARTIENDO DE LA ABERTURA DEL CANAL DE SALIDA (18), RESULTA UNA ABERTURA CIRCULAR (16) QUE SE AMPLIA RADIALMENTE HACIA AFUERA. POR ESO, EN EL SENTIDO DE CIERRE DE LA VALVULA, SE FORMA UNA DELGADA ZONA ESTANCA DIRECTAMENTE EN EL BORDE DE LA ABERTURA DEL CONDUCTO DE SALIDA
