Abstract
UNA VALVULA DE RECIRCULACION DE BAJA PRESION PARA REFRIGERACION DE UNA BOMBA CENTRIFUGA. UN BASTIDOR DE VALVULA (12) QUE TIENE UNA PRIMERA CAMARA (14) CON UNA TOMA (18) Y UNA PUERTA DE RECIRCULACION (22), Y UNA SEGUNDA CAMARA (16) CON UNA SALIDA (20). UNA VALVULA DE COMPROBACION DE PIEZA MULTIPLE (36) ENTRE LA PRIMERA Y SEGUNDA CAMARA PERMITE EL FLUJO DE LA PRIMERA CAMARA A LA SEGUNDA E IMPIDE EL FLUJO EN LA DIRECCION OPUESTA. UN VASTAGO DE VALVULA DESLIZABLE (23) ESTA ACOPLADO A LA VALVULA DE COMPROBACION Y EXTENDIENDOSE A TRAVES DE LA PRIMERA CAMARA MUEVE LA VALVULA DE COMPROBACION DE LA POSICION ABIERTA A CERRADA. UN MEDIO (42) ACOPLADO AL VASTAGO DE LA VALVULA AJUSTA EL VASTAGO DESLIZANTE DE LA VALVULA Y LA VALVULA DE COMPROBACION A LA POSICION CERRADA. UN MEDIO DE VALVULA DE RECIRCULACION (31-35-35A) FUNCIONALMENTE ACOPLADO AL VASTAGO DE VALVULA ABRE Y CIERRA LA PUERTA DE RECIRCULACION MENCIONADA, ABRIENDOSE EL MENCIONADO VASTAGO DE VALVULA DE RECIRCULACION CUANDO LA VALVULA DE COMPROBACION MENCIONADA ESTA CERRADA Y CERRANDOSE CUANDO LA VALVULA DE COMPROBACION ESTA ABIERTA.
