Abstract

EN UN ELEMENTO DE COMBUSTION PARA REACTORES DE AGUA A PRESION SE PREVE EN UN ORIFICIO 30 DE FIJACION DE LA PLACA DE CIERRE UN CASQUILLO 20 CON UNA BRIDA, QUE REBASA EL LADO B SUPERIOR DE LA PLACA DE CIERRE Y QUE POSEE UNA ROSCA 24 EXTERIOR EN UN CUELLO 23, QUE SOBRESALE DEL LADO A INFERIOR DE LA PLACA DE CIERRE. UN CASQUILLO 10 DEL EXTREMO SUPERIOR DEL TUBO DE GUIA GR POSEE UNA ROSCA 13 INTERIOR Y APOYA CON SU SUPERFICIE 11 FRONTAL EN EL LADO A INFERIOR DE LA PLACA DE CIERRE. UN PERFIL 12 DE CONTORNO DEL CASQUILLO PENETRA EN UN PERFIL 33 CORRESPONDIENTE DEL LADO INFERIOR DE LA PLACA DE CIERRE. ESTA UNION ROSCADA DISOLUBLE, APROPIADA TAMBIEN PARA TUBOS DE MEDIO DE REFRIGERACION DE ELEMENTOS DE COMBUSTION DE AGUA HIRVIENDO EXIGE UNA SECCION TRANSVERSAL MENOR DE LOS TALADROS 31,32 PARA EL MEDIO DE REFRIGERACION, AL MISMO TIEMPO, QUE NO ES NECESARIA UNA COMPENSACION INDIVIDUAL DE LAS TOLERANCIAS DE LAS UNIONES ROSCADAS DE UNA PLACA.
