Abstract

PARA CONTROL DE VALVULA EN INSTALACIONES SE UTILIZA UN REGULADOR (6) DE POSICION, PARA POSICIONAMIENTO DEL RECORRIDO O LA ABERTURA DE LA VALVULA DE REGULACION CORRESPONDIENTE A UNA ENTRADA. PARA LA EXACTITUD DE LA ESTABILIDAD Y LA BONDAD DE REGULACION DEL CIRCUITO REGULADOR DE LA INSTALACION, SE UTILIZA EN LA VALVULA (1) UN MIEMBRO DE AJUSTE, QUE SE ADAPTA AL VALOR DESEADO, GUIANDO CON IGUAL MODIFICACION DE RECORRIDO A LAS MISMAS MODIFICACIONES DE FLUJO DE PASO. A TRAVES DE LA GENERACION DE UNA NO LINEARIDAD ENTRE LA SEÑAL DE AJUSTE Y LA ABERTURA DE VALVULA SE CONSIGUE UNA LINEARIDAD ENTRE LA SEÑAL DE AJUSTE Y LA CANTIDAD DE FLUJO DE PASO. CON ELLO SE ELIGE PARA LA OBTENCION DE UN RECORRIDO DE ABERTURA DETERMINADO LA SEÑAL DE AJUSTE NECESARIA, QUE GENERA UNA FUNCION LINEAL ENTRE LA CANTIDAD DE FLUJO DE PASO Y LA SEÑAL DE AJUSTE. LA SEÑAL DE AJUSTE ASI EMITIDA SE GUIA AL REGULADOR DE POSICION PARA CONTROL DE LA VALVULA. EL REGULADOR DE POSICION SE EQUIPA CON ELLO CON UN CIRCUITO MICROPROCESADOR, QUE REGISTRA Y PROCESA LOS RESULTADOS DE LA DETERMINACION DE LA LINEA CARACTERISTICA DE OPERACION DE LA INSTALACION.
