Abstract

UNA VALVULA DE CONTROL DEL FLUJO DE UN FLUIDO COMPRENDE UN PRIMER (12) Y UN SEGUNDO (14) ELECTRICAMENTE CONDUCTOR SEPARADOS POR UN MEDIO ELECTRICAMENTE ACTIVO (16) QUE TIENE RESISTENCIA ELECTRICA. UN MIEMBRO DE ACCIONAMIENTO DE VALVULA (20) SE SITUA DE FORMA DESLIZABLE DENTRO DEL SEGUNDO CUERPO (14) EFECTUANDO UN CONTACTO ELECTRICO DESLIZANTE EN EL INTERIOR DEL MISMO. EL MIEMBRO DE ACCIONAMIENTO DE LA VALVULA (20) PUEDE MOVERSE DESDE UNA PRIMERA POSICION SEPARADA DEL PRIMER CUERPO (12) HASTA UNA SEGUNDA POSICION QUE CONECTA ELECTRICAMENTE EL PRIMER CUERPO (12) CON EL SEGUNDO CUERPO (14) FORMANDO DE ESTA FORMA UNA CONEXION DE BAJA RESISTENCIA ELECTRICA. EN SU PRIMERA POSICION SEPARADA DEL PRIMER CUERPO (12), LA RESISTENCIA DE LA CONEXION ELECTRICA ENTRE LOS CUERPOS (12, 14) DEPENDE DE LA RESISTENCIA ELECTRICA DEL MEDIO DE SEPARACION (16). UN CIRCUITO ELECTRICO CONECTADO A TRAVES DE LOS CUERPOS (12, 14) QUE INCLUYE UN RESISTOR DE LIMITACION DE CORRIENTE (R3) FORMA UN CIRCUITO DE DIVISION DE TENSION CON EL MEDIO DE SEPARACION (16) PARA HACER POSIBLE QUE SE OBTENGA UNA SEÑAL DE TENSION DE SALIDA INDICATIVA DEL CONTACTO DEL MIEMBRO DE ACCIONAMIENTO DE VALVULA (20) CON EL PRIMER CUERPO (12).
