Comporta pneum\u00e1tica de controlo do fluxo<\/strong> desempenha principalmente um papel de comuta\u00e7\u00e3o e regula\u00e7\u00e3o do fluxo em p\u00f3 e l\u00edquido sistemas de controlo de transporte<\/a>materiais granulares e de part\u00edculas pequenas.<\/p>\n

A Darko utiliza tecnologia estrangeira avan\u00e7ada especificamente concebida para a produ\u00e7\u00e3o de descarga de silos de homogeneiza\u00e7\u00e3o de mat\u00e9rias-primas e silo de cimento<\/a> equipamento. O dispositivo de acionamento deste produto adopta cilindros em forma de leque (120-100) e posicionadores (6DR5020-0NG0O-OAAO) para realizar a fun\u00e7\u00e3o de regula\u00e7\u00e3o do fluxo da v\u00e1lvula. \u00c9 um dispositivo ideal para regular o tamanho do caudal. Ajusta automaticamente a abertura atrav\u00e9s da entrada de sinais de controlo de 4~20mA para realizar a fun\u00e7\u00e3o de regula\u00e7\u00e3o.<\/p>\n

Carater\u00edsticas de desempenho<\/span><\/strong><\/span><\/h2>\n

 <\/p>\n

1. O design apresenta uma estrutura razo\u00e1vel e compacta que garante uma a\u00e7\u00e3o sens\u00edvel sem encravamento. Permite uma f\u00e1cil instala\u00e7\u00e3o e utiliza\u00e7\u00e3o, ao mesmo tempo que funciona com baixo ru\u00eddo e pequenas vibra\u00e7\u00f5es, tornando a manuten\u00e7\u00e3o simples.<\/p>\n

 <\/p>\n

2. O dispositivo de acionamento \u00e9 composto por um cilindro em forma de leque e um posicionador, permitindo uma regula\u00e7\u00e3o eficaz do fluxo.<\/p>\n

 <\/p>\n

3. O n\u00facleo da v\u00e1lvula \u00e9 constru\u00eddo em material resistente ao desgaste de alto desempenho, com uma superf\u00edcie cromada dura que proporciona um acabamento elevado e uma excelente resist\u00eancia ao desgaste. A sua abertura em forma de arco garante um fluxo de material suave.<\/p>\n

 <\/p>\n

O vedante do n\u00facleo da v\u00e1lvula utiliza feltro de alta qualidade e densidade que se ajusta firmemente \u00e0 superf\u00edcie exterior do arco. Os utilizadores podem ajustar o aperto entre o n\u00facleo da v\u00e1lvula e o feltro para obter um estado sem fugas.<\/p>\n

Princ\u00edpios de funcionamento<\/span><\/strong><\/span><\/h2>\n

 <\/p>\n

A comporta pneum\u00e1tica de regula\u00e7\u00e3o do caudal<\/strong> pode realizar as fun\u00e7\u00f5es de abertura, fecho e regula\u00e7\u00e3o sob o sinal de 4-20mA. Quando o atuador el\u00e9trico recebe um sinal de controlo de 4 mA, posiciona a v\u00e1lvula no estado totalmente fechado. Quando recebe um sinal de controlo de 20 mA, o atuador abre a v\u00e1lvula completamente. Sob a influ\u00eancia do sinal de controlo de 4-20 mA, o atuador mant\u00e9m a v\u00e1lvula num estado de regula\u00e7\u00e3o, permitindo ajustes \u00e0 abertura da v\u00e1lvula com base em qualquer valor de sinal dado. Este processo permite a fun\u00e7\u00e3o de regula\u00e7\u00e3o da v\u00e1lvula.<\/p>\n
