Abstract

Una unidad de acoplamiento de caja en T de un nebulizador de nucleo 24-NS-6041-16-A para un tubo de presion de reactor nuclear, la cual incluye un acoplamiento, de tuberia descendente y un sujetador, de la caja en T del nebulizador. El acoplamiento de la tuberia descendente incluye u n alojamiento externo cilindrico, una porcion central, y una pluralidad de aletas extendidas desde el alojamiento externo hacia la porcion central. El alojamiento externo esta acoplado con una tuberia descendente e incluye un reborde extendido. Un perno de extraccion se acopla en forma enroscada con un orificio axial en la porcion central, y conecta el acoplamiento de la tuberia descendente con el sujetador de la caja en T del nebulizador. El sujetador de la caja en T del nebulizador incluye un ancla que tiene una abertura de perno de extraccion y una pluralidad de patas extendidas desde una cara del ancla. Los bloques del sujetador estan conectados con el ancla. Los pernos de tope se extienden a traves de las aberturas, del perno de tope en los bloques de sujecion. Los elementos de sujecion estan conectados con los bloques de sujecion mediante pernos de sujecion. Una placa de sello que tiene una abertura de perno de extraccion esta acoplada con el ancla con una pluralidad de tornillos de ajuste.
