Abstract

LA SUSTITUCION SE REALIZA DESDE UNA ZONA DE INTERVENCION SITUADA POR ENCIMA DE LA CARA CONVEXA (1A) DE LA TAPA. SE EFECTUA EL MECANIZADO DEL ADAPTADO A SUSTITUIR TRAS EL DESMONTAJE DE SU MECANISMO DE CONTROL (13) Y DE UN MANGUITO TERMICO (4), INTRODUCIENDO UN UTILLAJE APROPIADO (14) POR EL EXTREMO SUPERIOR DEL ADAPTADOR (14) POR EL EXTREMO SUPERIOR DEL ADAPTADOR (3'') A SUBSTITUIR. SE REALIZA SUCESIVAMENTE UN MECANIZADO DE LA PARTE INFERIOR DEL ADAPTADOR Y DE UNA DE LA SOLDADURA DE ESTE ADAPTADOR, EL MECANIZADO DE UN CHAFLAN ESTRECHO EN LA SOLDADURA DEL ADAPTADOR A SUSTITUIR, UN REESCARIADO DE LA PARTE RESTANTE DEL ADAPTADOR A SUSTITUIR (3'') EN EL INTERIOR DE LA TAPA (1), UNA EXTRACCION DEL ADAPTADOR, LA COLOCACION POR ZUNCHADO EN FRIO DE UN ADAPTADOR DE SUSTITUCION Y LA SOLDADURA DEL ADAPTADOR DE SUSTITUCION.
