Abstract

UNA VALVULA DE LA RECIRCULACION AUTOMATICA (10) QUE TIENE UNA ENTRADA (16), UNA SALIDA PRINCIPAL (18) Y UN SALIDA DE RECIRCULACION (20). UN ELEMENTO DE VALVULA PRINCIPAL (28) RESPONSABLE DEL FLUJO ENTRE LA ENTRADA (16) Y LA SALIDA PRINCIPAL (18) Y UN ELEMENTO DE DESVIO, DEPENDIENTE DEL ELEMENTO DE VALVULA PRINCIPAL (28) QUE REGULA EL FLUJO DE FLUIDO A LA SALIDA DE RECIRCULACION (20). EL ELEMENTO DE DESVIO (32) COMPRENDE ORIFICIOS (52A, 52B) A TRAVES DE LOS CUALES EL FLUIDO FLUYE HACIA LA SALIDA DE RECIRCULACION (20). LOS ORIFICIOS (52A, 52B) ESTAN DISPUESTOS DE FORMA QUE CONTRARRESTEN LAS FUERZAS QUE EL FLUIDO EJERCE EN ELEMENTO DE DESVIO.
