Abstract
SISTEMA PARA CERRAR HERMETICAMENTE UNA TOBERA. CONSISTE EN UN POLIPASTO DE CADENA (10) QUE SOPORTA LA HERRAMIENTA DE INSTALACION QUE TIENE EN CADA EXTREMO UN TAPON DE CIERRE (20) PARA CERRAR HERMETICAMENTE UNA TOBERA (32) DE RAMA FRIA DIAMETRALMENTE OPUESTA UNA VEZ ALINEADOS LOS TAPONES MEDIANTE BASCULAS. MEDIANTE LA ROTACION DE UNA TUERCA TRANSVERSAL (34) QUE POSEE LA HERRAMIENTA, SE INSERTAN LOS TAPONES DE CIERRE DE LA TOBERA Y SE LES SOMETE A PRESION PARA CONSEGUIR HERMETICIDAD MEDIANTE UN GATO HIDRAULICO. POR ESTAR TODO EL SISTEMA SUMERGIDO EN AGUA DEL RECIPIENTE REACTOR, SE USA PARA CONTROL DEL MONTAJE UNA CAMARA DE TELEVISION (24) Y UNA LUZ SUBACUATICA (26).
