Abstract

SE PRESENTA UN DISPOSITIVO DE VALVULA PARA CONTROLAR EL SUMINISTRO DE GAS DESDE UNA FUENTE A PRESION ADECUADO PARA SU USO EN UN EYECTOR NEUMATICO EN UN APARATO DE CLASIFICACION DE PARTICULAS. EL DISPOSITIVO UTILIZA UN DIAFRAGMA (42) COMO UN MIEMBRO DE LA VALVULA DISPUESTO SOBRE UN PUERTO DE SALIDA (52) DE UNA CAMARA (61, 63) QUE ESTA EN COMUNICACION SUBSTANCIALMENTE CONTINUA CON LA FUENTE DE GAS O DE AIRE BAJO PRESION. AMBOS LADOS DEL DIAFRAGMA ESTAN EXPUESTOS AL GAS O AL AIRE A PRESION EN LA CAMARA. POR ESTA RAZON, Y A CAUSA DE QUE EL DIAFRAGMA MISMO AJUSTA EN EL PUERTO DE SALIDA PARA CERRARLO, CUANDO SE APLICA UNA PRESION DE ENTRADA, HAY UNA PRESION DIFERENCIAL QUE DEFORMA ELASTICAMENTE EL DIAFRAGMA PARA CERRAR EL PUERTO DE SALIDA. EL DIAFRAGMA TIENE UN ELEMENTO PIEZOELECTRICO (44) Y EL DISPOSITIVO DE VALVULA INCLUYE UN CIRCUITO ELECTRICO (56, 58) ACCIONABLE PARA ACTIVAR SELECTIVAMENTE EL ELEMENTO PIEZOELECTRICO Y PARA EXTRAER EL MIEMBRO DE LA VALVULA DEL PUERTO DE SALIDA PARA ADMITIR GASO AIRE A PRESION AL INTERIOR DE LA MISMA.
