Abstract

EL SISTEMA ES APLICABLE EN AQUEL TIPO DE VALVULAS EN CUYO CUERPO BASE (1) VA DISPUESTA UNA CAJA (2) EN FUNCIONES DE MEDIO DE GUIADO PARA UN OBTURADOR (5) CAPAZ DE CERRAR ORIFICIOS (8) SITUADOS EN LA PARED DE LA CAJA (2). DICHO OBTURADOR (5) CUENTA CON UNA PROLONGACION O PUNTA TRONCO-CONICA (11) QUE, DEPENDIENDO DE LA APERTURA O DESPLAZAMIENTO DEL MISMO, JUEGA CON UNA SERIE DE RANURAS (10) PRACTICADAS EN LA SUPERFICIE INCLINADA INTERNA DE UN ANILLO-ASIENTO (16) MONTADO SOBRE ELCUERPO (1) DE LA VALVULA, COMO CONTINUACION AXIAL DE LA CAJA (2), PRODUCIENDO UNAS EXPANSIONES/RESTRICCIONES DE VOLUMEN QUE AFECTAN DIRECTAMENTE AL FLUIDO PARA PRODUCIR SALTOS DE PRESION INTERMEDIOS ENTRE LA PRESION DE ENTRADA (9) Y LA PRESION DE SALIDA (4), EVITANDOSE CON ELLO LAS CAVITACIONES Y POR LO TANTO EL DESGASTE DE LAS PARTES INTERNAS DE LA VALVULA.
