Abstract

EL SISTEMA CONSTA DE UN CONECTOR (40) Y UNA HERRAMIENTA (100) PARA INSTALARLO EN UN ORIFICIO DE PASO DE FLUJO (11) QUE TIENE UNA ENTRADA (37) BISELADA Y OTRA NO BISELADA (39) QUE PARTE DESDE LA PRIMERA. EL CONECTOR (40) CONSTA DE UN CUERPO (42) QUE INCLUYE UN MANDRIL (47) PARA EXPANDIR UNA PARTE DISTANTE (48) DEL CUERPO Y SELLARLA HERMETICAMENTE CON LA PARED DE LA PARTE NO BISELADA DEL ORIFICIO DE PASO DE FLUJO, Y UN ANILLO DE RETENCION (44) SITUADO SOBRE, Y COOPERANDO CON, EL CUERPO PARA DETERMINAR LA POSICION AXIAL DEL MISMO DENTRO DEL AGUJERO DEL ORIFICIO DE PASO DE FLUJO. EL ANILLO DE RETENCION (44) ES DESLIZABLE EN EL CUERPO (42) DENTRO DE LIMITES QUE PERMITEN AL CONECTOR (40) ACORTARSE TELESCOPICAMENTE PARA FACILITAR LA INSTALACION DEL MISMO Y EXTENDERSE, TAMBIEN TELESCOPICAMENTE, HASTA UNA LONGITUD QUE GARANTIZA LA COLOCACION APROPIADA DE LA PARTE DISTAL EXPANDIBLE DEL CUERPO DENTRO DE LA PARTE NO BISELADA DEL ORIFICIO DE PASO DE FLUJO A CONECTAR. LA HERRAMIENTA (100) CONSTA DE UN ARMAZON (116) QUE SOSTIENE UN BASTIDOR (114) DE SUJECION DEL CONECTOR PARA MOVIMIENTO ENTRE UNA POSICION RETRAIDA Y UNA POSICION AVANZADA DE INSERCION DEL CONECTOR, Y UN PISTON HIDRAULICO COMPACTO (112) PARA LLEVAR EL MANDRIL DEL CONECTOR (40) A SU POSICION DE EXPANSION DEL CUERPO. EL SISTEMA ES PARTICULARMENTE ADECUADO PARA SU UTILIZACION EN LA CONEXION DE ORIFICIOS DE PASO DE FLUJO EN EL CILINDRO DEL NUCLEO DE REACTORES NUCLEARES.
