    怎麼樣使氣動球閥的壽命更長久

    [來源:原創] [作者:admin] [日期:14-11-22] [點擊:]

    氣動球閥是閥門裡使用廣泛的一種通用閥門,使用量大,消耗也快,所以,合理的維修保養,不僅可以提高工作效率,還可以減少檢修時間,節約更換成本。
      
      想使氣動球閥性能穩定,壽命長久,氣動球閥建議注意以下因素:
      
      一、使用前,應用水清洗管道和閥體過流部分,以防殘留鐵屑和其它雜物進入閥體内腔。
      
      二、球閥在關閉狀态下,閥體内仍然殘留部分介質,也承受着一定壓力。在檢修球閥之前,要先關閉球閥前的切斷閥,打開需要檢修的球閥,完全釋放閥體内部壓力。如果是電動球閥或氣動球閥,則應該首先斷開電源和氣源。
      
      三、.一般軟密封球閥均使用四氟(PTFE)作為密封材料,硬密封球閥密封面為金屬堆焊而成。如需對管道球閥進行清洗,在拆卸時需謹慎防止損壞密封圈而洩露。
      
      四、法蘭球閥拆裝時,法蘭上的螺栓螺母應先固定,然後将所有螺母稍緊,最後用勁固定好。如先将個别螺母強行固定好,再固定其他螺母,法蘭面之間會因受裡不勻導緻墊面損壞或破裂,導緻閥門法蘭對接出介質洩露。
