Abstract

TUBO ACCESORIO PARA EL ESTRANGULADO DE FLUJOS LIQUIDOS EN AUSENCIA DE CAVITACION, ESPECIALMENTE TUBO ACCESORIO DE REGULACION PARA EL ESTRANGULADO VARIABLE, TAN EXENTO DE CAVITACION COMO SEA POSIBLE, DE FLUJOS QUE FLUYEN POR TUBERIAS, DESDE UN PRIMER NIVEL DE PRESION HASTA UN SEGUNDO NIVEL DE PRESION, INFERIOR AL ANTERIOR, SEGUN UNA MAGNITUD DE REGULACION PREDETERMINADA. CONSTA DE DOS CHAPALETAS DE REGULACION (K1, K2); DE DOS ESTRANGULACIONES FIJAS (D1, D2) CONECTADAS AGUAS ABAJO EN EL SENTIDO DEL FLUJO CON LAS DOS CHAPALETAS DE REGULACION (K1, K2); DE UNA BARRERA DE ACOPLAMIENTO (2) QUE ACOPLA ENTRE SI A LAS DOS CHAPALETAS; DE UN DISPOSITIVO ESTABILIZADOR (3) QUE SIRVE PARA EL AJUSTE LONGITUDINAL DE LA BARRA DE ACOPLAMIENTO (2); Y DE UN MOTOR DE ACCIONAMIENTO (M).ACCESSORY TUBE FOR THE CHOKING OF LIQUID FLOWS IN THE ABSENCE OF CAVITATION, ESPECIALLY REGULATION ACCESSORY TUBE FOR THE VARIABLE CHOKING, AS FREE FROM CAVITATION AS POSSIBLE, OF FLOWS FLOWING THROUGH PIPES, FROM A FIRST PRESSURE LEVEL TO A SECOND PRESSURE LEVEL , LOWER THAN THE PREVIOUS, ACCORDING TO A PREDETERMINED REGULATION MAGNITUDE. IT CONSISTS OF TWO REGULATION CLAMPS (K1, K2); OF TWO FIXED CHOKES (D1, D2) CONNECTED DOWNSTREAM IN THE DIRECTION OF THE FLOW WITH THE TWO REGULATION FLAPES (K1, K2); OF A COUPLING BARRIER (2) THAT COUPLERS THE TWO CLAMPS TOGETHER; OF A STABILIZER DEVICE (3) WHICH SERVES FOR THE LONGITUDINAL ADJUSTMENT OF THE COUPLING BAR (2); AND A DRIVE MOTOR (M).
