Abstract

DISPOSITIVO DE BLOQUEO DE TOBERAS EN GENERADORES DE VAPOR. EL TAPON (22) ESTA CONSTITUIDO POR UNOS PERFILES DE PLACA (24, 26, 28) QUE SON ENSAMBLADOS DENTRO DEL GENERADOR DE VAPOR CON LA MISMA SECCION QUE LA TOBERA A TAPONAR Y QUE TIENEN UNOS BORDES ELEVADOS QUE ADEMAS DE REFORZAR, PERMITEN LA COLOCACION DE UN CORDON INFLABLE (36, 38) QUE HARA EL CIERRE HERMETICO. EL TAPON SE FIJA A LA TOBERA POR UNOS PASADORES (42) QUE SE INTRODUCEN EN LAS PAREDES LATERALES (46) DE LA TOBERA. LOS CORDONES INFLABLES SE INFLAN MEDIANTE UNAS VALVULAS DE INFLAR.
