襯氟閥門是怎么解決其他閥門不足的點?

發布日期:2016-01-07    點擊數:

隨著現代工業的飛躍發展,襯氟閥門及其各類管路附件在石油、印染、化工等各領域中得到迅速應用的推廣,顯示了強大的生命力,做為工程中首選項目已引起各工程設計單位和施工單位的極大關注與青睞,是一種極具市場潛力的朝陽產品。

襯氟閥門

在抗腐蝕材料中,聚四氟乙烯具有不可比擬的優異性能,除了熔融堿金屬、元素氟及芳香烴類外,在各種濃度的鹽酸、硫酸、硝酸、王水、有機酸、強氧化劑、濃、稀酸交替、堿交替和各種有機溶劑中均呈隨性反應,將聚四氟乙烯內襯于閥門內壁,即克服聚四氟乙烯材料強度低的缺點,又解決了閥門主體材料抗腐蝕性能差、成本高的不足。另外,聚四氟乙烯除了具有優異的化學穩定性外,其防污、防粘性好、動靜摩擦系數值極小且相近,減摩潤滑性能好,將其做為閥門啟、閉件的密封副,要降低密封面間磨擦力,減小閥門操作扭矩,提高產品使用壽命,其使用范圍還可擴展到食品、醫藥工業。
