Abstract

SE DESCRIBE UNA VALVULA DE RETENCION PARA DIFERENCIAS DE PRESION EN EL RANGO ENTRE 0,1 HASTA 0,002 BARES (0,004 LIBRAS POR PULGADA CUADRADA LEIDAS EN EL MANOMETRO, PSIG), QUE CONSISTE EN DOS CAMARAS DE CONEXION (1,2) Y EN UN DISCO DE MEMBRANA (3) EMPOTRADO ENTRE AMBAS QUE ESTA HECHO DE UN MATERIAL FLEXIBLE, QUE ANTE LA SOBREPRESION PRODUCIDA POR UN ANILLO DE OBTURACION (12) ES CAPAZ DE LEVANTARSE, FORMANDOSE UNA SECCION DE PASO Y ACABANDO DE MANERA SEGURA Y EN UN TIEMPO MINIMO CON LA SOBREPRESION. SE CONSIGUE UNA TENSION PREVIA ALTA Y CON ELLO UNOS TIEMPOS DE RESPUESTA MAS CORTOS Y CON MAYOR SEGURIDAD GRACIAS A VARIOS FACTORES: A QUE EXISTE EN LA ZONA CENTRAL (3A) UN DISCO DE MEMBRANA (3) CON UNA DENSIDAD REGULAR QUE DISPONE EN SU PERIMETRO EXTERIOR (3B) DE UN ABOMBAMIENTO (3C) EN FORMA DE ANILLO; A LAS FORMAS GEOMETRICAS QUE RODEAN LAS CAMARAS (4A,4B) QUE UNEN EL ABOMBAMIENTO (3C) POR TODAS PARTES EXCEPTO POR UNA ADMISION (4C) FORMANDO UNA CAVIDAD (5); Y GRACIAS A UNA PARED INTERNA (6) DELA CAVIDAD, COMBADA HACIA AFUERA, APOYADA DE TAL MODO EN EL ABOMBAMIENTO (3C), QUE EN EL MONTAJE DE LAS FORMAS GEOMETRICAS QUE RODEAN A AMBAS CAMARAS (4A,4B), SOBRE EL DISCO DE MEMBRANA (3) SE TRANSMITEN LAS FUERZAS DE TRACCION RADIALMENTE.
