Abstract

VALVULA DE PULVERIZACION PARA INSTALACION DE PULVERIZACION DE CERA EN EL VACIO, PARA LA UNION DE UN MOLDE A PULVERIZAR CON CERA CON UN ESPACIO (14) CON VACIO, O CON UN ESPACIO (12) CON CERA LIQUIDA EN LA INSTALACION DE PULVERIZACION DE CERA EN EL VACIO, CON UNA POSICION CERRADA, UNA POSICION DE EVACUACION Y UNA POSICION DE PULVERIZACION DE CERA, CON UN CUERPO BASE DE LA VALVULA (20) Y CON UN ELEMENTO DE CONEXION (26), AL CUAL SE PUEDE PRESIONAR EL MOLDE, PARA LO CUAL EL ELEMENTO DE CONEXION ESTA SUJETO A UN TUBO (24), CUYO EXTREMO SITUADO OPUESTO AL ELEMENTO DE CONEXION ESTA CERRADO Y EL CUAL SE PUEDE ENCAJAR EN EL CUERPO BASICO DE LA VALVULA, PARA LO QUE EL TUBO TIENE POR LO MENOS UNA ABERTURA LATERAL (40,52), POR MEDIO DE LA CUAL UNE EN DEPENDENCIA DE LA PROFUNDIDAD DE ENCAJADO, PRIMERO EL ESPACIO CON VACIO Y A CONTINUACION CON MAYOR PROFUNDIDAD DE ENCAJADO EL ESPACIO CON CERA CON EL ELEMENTO DE CONEXION. MEDIANTE ESTA DISPOSICION SE PUEDE LOGRAR EL DESARROLLO DE LA PULVERIZACION (EVACUACION DEL MOLDE, INTERRUPCION DEL VACIO Y LIBERACION DE LA CERA), CON MUY PEQUEÑO GASTO TECNICO Y, SIN EMBARGO, GRAN FACILIDAD DE MANEJO.
