襯氟塑防腐閥門在石油、化工、醫藥、冶金、電力等行業接觸酸堿等強腐蝕介質的裝置上已得到了廣泛的應用,但對如何選好、用好襯氟塑閥門

襯氟塑防腐閥門在石油、化工、醫藥、冶金、電力等行業接觸酸堿等強腐蝕介質的裝置上已得到了廣泛的應用,但對如何選好、用好襯氟塑閥門,根據我們廣大用戶多年來現場應用的經驗,對襯氟塑防腐閥門選用時應對介質溫度、壓力、壓差等幾項使用條件提出如下注意事項襯膠閥門:

壓力、壓差控制范圍 

壓力、壓差應控制在允許范圍內。尤其是波紋管密封的襯氟塑調節閥、截止閥。因波紋管是四氟材料制作的,壓力、壓差大,容易導致波紋管破裂襯膠閥門。波紋管密封的襯氟塑調節閥,使用條件壓力、壓差大的,可改為四氟填料密封。

適用介質   

襯氟塑閥門使用的介質條件不宜有硬質顆粒、結晶、雜質等,以免閥門在開啟、關閉的運行中磨破閥芯、閥座的襯氟塑層或四氟波紋管。對介質有硬質顆粒、結晶、雜質的,選用時,閥芯、閥座可改用哈氏合金襯膠閥門。
