Abstract

EN UN EQUIPO DE SEGURIDAD CONTRA FALLO DE SOBREPRESION DE UN RECIPIENTE A PRESION DE REACTOR NUCLEAR EN CASO DE REFRIGERACION INSUFICIENTE DEL NUCLEO, SE HA PROVISTO UNA DESCARGA DE PRESION DEPENDIENTE DE LA TEMPERATURA. UNA VALVULA (4) DE LIBERACION DE PRESION QUE BLOQUEA NORMALMENTE POR MEDIO DE UNA PIEZA (8) DE CIERRE EL FLUJO ENTRE EL INTERIOR DEL RECIPIENTE (11) A PRESION Y UN CONDUCTO (10) DE DESCARGA A PRESION, ESTA AJUSTADA DE FORMA ESTANCA A LA PRESION EN UNA PARED (1) DEL RECIPIENTE (11) A PRESION. LA PIEZA (8) DE CIERRE ESTA SUJETA EN SU POSICION CERRADA POR MEDIO DE UN DISPOSITIVO (16) DE RETENCION QUE PUEDE SER LIBERADO DEPENDIENDO DE UN UMBRAL DE TEMPERATURA. UN ELEMENTO (13) DE TRANSMISION DE FUERZA ESTA ACOPLADO MEDIANTE UNO DE SUS EXTREMOS (13.1) A LA PIEZA (13) DE CIERRE Y SU OTRO EXTREMO (13.2) SE PROYECTA DENTRO DEL INTERIOR DEL RECIPIENTE (11) A PRESION QUE ESTA ASEGURADO PARA SER INCLUIDO EN LOS ELEMENTOS (15) DEL RECIPIENTE (11) A PRESION POR MEDIO DE UN ELEMENTO (20)DE BLOQUEO DEL TIPO DE SOLDADURA FUNDIBLE QUE SE FUNDE CUANDO SE ALCANZA UN UMBRAL DE TEMPERATURA DE APROXIMADAMENTE 700 ON CONJUNTAMENTE CON LA PIEZA (8) DE CIERRE MEDIANTE LA LIBERACION DEL RECIPIENTE (11) DE VALVULA, ABRIENDO DE ESTA FORMA LA VALVULA (8) DE DESCARGA A PRESION DE FORMA DEPENDIENTE DE LA DIFERENCIAL DE PRESION. EL ELEMENTO (13) DE TRANSMISION DE FUERZA PUEDE SER TAMBIEN DEFLECTADO DENTRO DE UNA POSICION DE APERTURA DE VALVULA MEDIANTE UN ELEMENTO PERFILADO EN L, POR EJEMPLO UNA BARRA METALICA DISPONIENDO DE UN COEFICIENTE ALTO DE EXPANSION LINEAL.
