Introdu\u00e7\u00e3o ao produto<\/h4>
\u00a0<\/div>
A v\u00e1lvula de amostragem com reinicializa\u00e7\u00e3o autom\u00e1tica da WANAN (modelo: s\u00e9rie WA-ZF) \u00e9 um dispositivo de amostragem hermeticamente vedado, com reinicializa\u00e7\u00e3o autom\u00e1tica e anti-vazamento, especialmente projetado para petr\u00f3leo, produtos qu\u00edmicos, prote\u00e7\u00e3o ambiental e outras condi\u00e7\u00f5es de trabalho. Adotando o reset autom\u00e1tico da mola e a estrutura de fluxo de canal duplo, ela \u00e9 amplamente usada para amostragem segura de meios corrosivos, de alta press\u00e3o e alta temperatura.<\/div>

Princ\u00edpio de funcionamento<\/h4>
\u00a0<\/div>
  1. Abertura<\/strong>: Pressione ou gire manualmente a al\u00e7a para levantar o n\u00facleo da v\u00e1lvula, abrindo o caminho do fluxo principal e a porta de amostragem para amostragem do meio.<\/li>
  2. Reinicializa\u00e7\u00e3o e fechamento autom\u00e1ticos<\/strong>: Depois de soltar a al\u00e7a, a mola de alta resist\u00eancia incorporada redefine instantaneamente o n\u00facleo da v\u00e1lvula, realizando a veda\u00e7\u00e3o dupla da passagem principal e da porta de amostragem com vazamento zero e sem res\u00edduos.<\/li>
  3. Projeto de seguran\u00e7a<\/strong>: Equipado com porta de ventila\u00e7\u00e3o\/drenagem para purga antes da amostragem e descarga residual ap\u00f3s a amostragem para evitar contamina\u00e7\u00e3o cruzada.<\/li><\/ol>
