Abstract

UNA HERRAMIENTA PRESURIZABLE PARA COLOCAR UN MANGUITO EN UN TUBO COLINDANTE Y LA OBTURACION ESTANCA A LA PRESION DEL MANGUITO EN EL TUBO PARA REPARAR ESCAPES EN EL TUBO. LA HERRAMIENTA INCLUYE UN ALOJAMIENTO QUE CONTIENE UN PISTON MOVIL AXIALMENTE Y UNA PARTE DE DIAMETRO REDUCIDO DELANTERA Y QUE TIENE UNA UNIDAD DE EXPANSION ELASTICA PARA INSERTARLA EN EL MANGUITO Y EN EL TUBO EN UNA LAMINA DEL TUBO. LA UNIDAD DE EXPANSION CONSTA DE AL MENOS DOS ANILLOS ELASTICOS COMPUESTOS DE UN MATERIAL ELASTOMERO Y CADA UNO DE ESTOS CON UN BISEL PROVISTO EN EL FILO EXTERIOR DE LAS CARAS DELANTERA Y POSTERIOR DE LA UNIDAD. AL PRESURIZAR UN PUERTO EN EL EXTREMO FRONTAL DEL ALOJAMIENTO, EL PISTON SE MUEVE HACIA ATRAS PARA COMPRIMIRSE AXIALMENTE Y EXPANDIR LOS ANILLOS DE EXPANSION RADIALMENTE HACIA AFUERA SUFICIENTEMENTE COMO PARA EXPANDIR EL MANGUITO FIRMEMENTE EN EL TUBO Y PROPORCIONAR UN CIERRE ESTANCO A LA PRESION ENTRE LOS MISMOS. SIGUIENDO DICHA EXPANSION DEL MANGUITO, EL PISTON ES PRESURIZADO Y MOVIDOHACIA ADELANTE PARA LIBERAR LA COMPRESION DE LOS ANILLOS DE LA UNIDAD DE EXPANSION, PARA QUE LA HERRAMIENTA PUEDA SER FACILMENTE RETIRADA DEL MANGUITO EXPANDIDO Y EL TUBO E INSERTADA EN OTRO MANGUITO Y TUBO PARA REPETIDOS USOS.A PRESSURIZABLE TOOL FOR PLACING A SLEEVE INTO AN ADJUSTABLE TUBE AND SEALING PRESSURE OF SLEEVE IN TUBE TO REPAIR LEAKS IN TUBE. THE TOOL INCLUDES A HOUSING CONTAINING AN AXIALLY MOBILE PISTON AND A PART OF REDUCED FRONT DIAMETER AND THAT HAS AN ELASTIC EXPANSION UNIT TO INSERT IT INTO THE SLEEVE AND IN THE TUBE IN A TUBE SHEET. THE EXPANSION UNIT CONSISTS OF AT LEAST TWO ELASTIC RINGS COMPOSED OF AN ELASTOMER MATERIAL AND EACH OF THESE WITH A BEVEL PROVIDED ON THE EXTERNAL EDGE OF THE FRONT AND REAR FACES OF THE UNIT. WHEN PRESSURIZING A PORT AT THE FRONT END OF THE ACCOMMODATION, THE PISTON IS MOVED BACKWARD TO COMPRESS AXIALALLY AND EXPAND THE EXPANSION RINGS RADIALLY OUTWARD SUFFICIALLY INTO THE SEA AND IN THE TUBE IN THE TUBE. . FOLLOWING SUCH EXPANSION OF THE HOSE, THE PISTON IS PRESSURIZED AND MOVED FORWARD TO RELEASE THE COMPRESSION OF THE RINGS OF THE EXPANSION UNIT, SO THAT THE TOOL CAN BE EASILY REMOVED FROM THE EXPANDED SLEEVE AND ANOTHER TUBE INSERT. .
