Abstract

EN CONOCIDAS VALVULAS ACCIONABLES ELECTROMAGNETICAMENTE CON UN RACOR DE EMPALME UTILIZADO COMO NUCLEO Y QUE LLEVA UNA BOBINA MAGNETICA. LAS VALVULAS SE RODEAN POR UNA CARCASA MACIZA DE METAL FERROMAGNETICO. LA PRODUCCION DE LA CARCASA SE EFECTUA MEDIANTE ELEVADOS COSTES Y TIENE UNAS DIMENSIONES EXTERNAS DEMASIADOS GRANDES PARA PRODUCIRLAS EN SERIE. LA NUEVA CONFIGURACION DE LA VALVULA POSIBILITA JUNTO A UNA PRODUCCION SENCILLA LA REDUCCION DE LAS DIMENSIONES EXTERIORES DE LAS VALVULAS. EN LA NUEVA VALVULA ESTA PREVISTA UNA ENVUELTA (24) DE MATERIAL SINTETICO RODEANDO EXTERIORMENTE EL RACOR (1) DE EMPALME Y LA BOBINA MAGNETICA (3) QUE CONTIENE ELEMENTOS (27,28) FERROMAGNETICO CONDUCIENDO LINEAS DE CAMPO MAGNETICO RODEANDO LA BOBINA MAGNETICA (3). LOS ELEMENTOS FERROMAGNETICOS SE FORMAN A TRAVES DE ELEMENTOS CONDUCTORES (28) Y MATERIA DE RELLENO (27) CON PROPIEDADES FERROMAGNETICAS QUE RODEA PARCIALMENTE Y PERIFERICAMENTE LA BOBINA MAGNETICA (3). LA CONFIGURACION DE LA VALVULA ES APROPIADO PARA GRUPOS ACCIONABLES ELECTROMAGNETICAMENTE.
