Abstract

PERFECCIONAMIENTOS EN LOS SISTEMAS DE MANDO DE CAUDALES DE FLUIDOS.COMPRENDE UNA TOBERA (T) QUE FORMA UN CONVERGENTE (101) DOTADA DE MEDIOS DE TOMA DE PRESION ESTATICA (102) EN UN PUNTO VARIABLE DEL CONVERGENTE; VALVULA REGULADORA (VR) CON UN OBTURADOR (119) MOVIL; MEDIOS (120, 109, 129) PARA HACER VARIAR LA POSICION DEL OBTURADOR EN FUNCION DE LA PRESION ESTATICA TOMADA EN EL CONVERGENTE; MEDIOS (121) PARA HACER VARIAR EL PUNTO DE TOMA DE PRESION ESTATICA EN EL CONVERGENTE EN FUNCION DEL CAUDAL O LA PRESION DEL FLUIDO, DE FORMA QUE UNA VARIACION DEL CAUDAL O LA PRESION ALREDEDOR DEL VALOR DE CONSIGNA PROVOCA UNA MODIFICACION EN LA POSICION DEL OBTURADOR QUE LLEVA A UNA MODIFICACION ANTAGONISTA DEL CAUDAL HASTA RECUPERAR EL VALOR DE CONSIGNA, DE MANERA QUE EL OBTURADOR SEA MANIOBRADO POR LA CAIDA DE PRESION PRODUCIDA EN EL SISTEMA.
