A465VB V\u00e1lvula de Drenaje Inferior<\/figcaption><\/figure>\n

Las V\u00e1lvulas de Drenaje Inferior se pueden a\u00f1adir a la mayor\u00eda de los reactores Parr.\u00a0<\/strong>Estas v\u00e1lvulas son particularmente \u00fatiles para los que trabajan con pol\u00edmeros u otros materiales que deben ser descargados del reactor mientras est\u00e1n todav\u00eda calientes y antes de que solidifiquen. Estas v\u00e1lvulas son muy \u00fatiles para recipientes de 1 gal\u00f3n y m\u00e1s grandes, son demasiado grandes para levantarlos c\u00f3modamente desde el calefactor para la recuperaci\u00f3n de producto. Las v\u00e1lvulas de fondo rara vez se instalan en los reactores micro y mini, por sus peque\u00f1os vol\u00famenes y recipientes de pesos ligeros.<\/p>\n

La v\u00e1lvula de Drenaje Inferior est\u00e1ndar<\/strong> es un v\u00e1stago ascendente que est\u00e1 al nivel del fondo del interior del recipiente de modo que no hay espacio muerto entre el fondo del recipiente y el punto de cierre de la v\u00e1lvula. En la posici\u00f3n totalmente abierta el v\u00e1stago se retrae completamente para dar paso libre y drenar el recipiente.<\/p>\n

Cuando la v\u00e1lvula se vuelve a cerrar, cualquier material que est\u00e9 en el pasaje ser\u00e1 empujado de nuevo al reactor por el v\u00e1stago ascendente. Las v\u00e1lvulas con un pasaje libre de 3\/8 pulgadas de di\u00e1metro se recomiendan para recipientes con vol\u00famenes de 1000 ml a 2 galones. Una v\u00e1lvula de 1\/4 pulg. est\u00e1 disponible para recipientes de 600 o m\u00e1s peque\u00f1os. V\u00e1lvulas de alta presi\u00f3n y de di\u00e1metro mayor est\u00e1n disponibles cuando se requieran.<\/p>\n

Estas v\u00e1lvulas soportar\u00e1n<\/strong> las presiones y temperaturas de operaci\u00f3n complete de los recipientes en los que se instalan. Est\u00e1n disponibles en todos los materiales de fabricaci\u00f3n de Parr. Los usuarios tambi\u00e9n pueden especificar que un reactor solicitado con v\u00e1lvula de fondo tenga un fondo c\u00f3nico para que drene f\u00e1cilmente a trav\u00e9s de la apertura de la v\u00e1lvula.<\/p>\n

No todos los reactores Parr aceptar\u00e1n una v\u00e1lvula de drenaje inferior. Dado que la v\u00e1lvula se extiende aproximadamente 8 pulgadas por debajo del fondo del recipiente, el recipiente completo debe ser elevado esa distancia para colocar la v\u00e1lvula. Esto hace que algunos Modelos queden demasiado altos para su operaci\u00f3n en una mesa de trabajo. Las tablas de especificaciones de cada Modelo determinar\u00e1n los reactores en los que puede ser instalado f\u00e1cilmente un Drenaje Inferior y, aquellos que no aceptar\u00e1n un drenaje de fondo, o los que requieren modificaciones personalizadas del elemento calefactor y base de soporte para dar cabida a una v\u00e1lvula de fondo.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n

Las v\u00e1lvulas de aguja y v\u00e1lvulas de bola tambi\u00e9n se pueden instalar como v\u00e1lvulas de drenaje inferior. Las v\u00e1lvulas de aguja se utilizan generalmente en los reactores m\u00e1s peque\u00f1os. Mientras que las v\u00e1lvulas de bola se pueden utilizar para pasajes de descarga grandes, son generalmente limitadas en sus capacidades de temperatura \/ presi\u00f3n de operaci\u00f3n y dejan un espacio muerto bastante grande entre el fondo del recipiente y el asiento de la v\u00e1lvula.<\/p>\n","protected":false},"excerpt":{"rendered":"
