安裝說明:

1.真空電磁閥安裝前應仔細閱讀產品的使用說明書,查核產品是否完全符合使用要求,熟悉安裝要點,做好準備工作。
2.安裝時真空電磁閥線圈向上,并保持垂直位置,真空電磁閥上箭頭或標記應與管道流向一致,不得安裝在有濺水或漏水的地方。
3.接管之前用0.3MPa的壓力對管道充分沖洗,把管道中的金屬粉末密封材料殘留,銹垢等完全清除;真空電磁閥的工作介質應清潔無顆粒; 雜質,建議閥前安裝過濾器,蒸汽管路安裝疏水閥進水電磁閥內件表面上的污物及過濾器,須定期清潔干凈。
4.在真空電磁閥發生故障時,為了及時隔離真空電磁閥,并保證系統正常運行,最好安裝旁路裝置。
5.不要將真空電磁閥安裝于管道低凹處,以免蒸汽冷凝水,雜質等沉淀在閥內而妨礙動作。
6.普通型真空電磁閥不可在易燃易爆危險場合使用。
7.在管道剛性不足情況下,建議把真空電磁閥閥前后管子用支架固定,以防真空電磁閥作時引起振動。
8.真空電磁閥前后管道上需裝壓力表,以便觀察。
