Abstract

SISTEMA DETECTOR DE FLUJO PARA VOLUMEN PREDETERMINADO. CONSTA DE UN CUERPO (1) CON ENTRADA Y SALIDA, UNA VALVULA (2) SENSIBLE AL FLUJO Y QUE COMPRENDE UN ASIENTO (A), UN MIEMBRO MOVIL (B) HACIA Y DESDE EL ASIENTO DE LA VALVULA, MEDIOS DE CARGA (C) QUE EMPUJAN EL (B) A UNA POSICION CERRADA, UN ORIFICIO DE CONTROL DE FLUJO (D) ABIERTO AL FLUJO MAS ALLA DEL MIEMBRO DE VALVULA ENTRE LA ENTRADA Y SALIDA DEL ALOJAMIENTO UN PASO (E) DE FLUJO PARA CIRCULACION POR EL MIEMBRO MOVIL (B) CUANDO ESTA CERRADO; UN INDICADOR DE PRESION DIFERENCIAL (3) QUE TIENE ELEMENTOS MAGNETICOS (A) DE ACTUACION E INDICACION COOPERANTES, UN PRIMER PASO (B) DE FLUIDO QUE COMUNICA PRESION DE FLUIDO AGUAS ARRIBA EN EL PASO DE FLUIDO DEL ALOJAMIENTO ANTES DEL MIEMBRO DE VALVULA Y UN SEGUNDO PASO A LA SEGUNDA CARA DE PRESION, MEDIOS (C) DE CARGA RETENEDORES DEL ELEMENTO DE ACTUACION EN UNA PRIMERA POSICION DE NO INDICACION A DIFERENCIAS DE PRESIONES. HASTA UN MINIMO PREDETERMINADO, Y A DIFERENCIAS QUE EXCEDEN DEL MINIMO SE MUEVEN HACIA AFUERA DEL ELEMENTO INDICADOR Y LO LIBERAN PARA SEÑALAR LA CONSECUCION DE DICHA DIFERENCIA DE PRESIONES, MEDIOS (D) EN EL SEGUNDO PASO DE FLUIDO RETARDADORES DE LA COMUNICACION DE PRESION DE FLUIDO A TRAVES DE ELLOS PARA IMPEDIR LA ACTUACION DEL ELEMENTO CUANDO SE ABRE LA VALVULA, MIENTRAS EL FLUJO ESTA AUMENTADO; CUANDO ES MOVIDO EL MIEMBRO (4) DE VALVULA FUERA DE PRESIONES ENTRE LOS PASOS DE FLUIDO PRIMERO Y SEGUNDO HASTA POR DEBAJO DEL MINIMO PREDETERMINADO.
