                                                                                                                                  氣動球閥具體分類有:浮動球氣動球閥,固定球氣動球閥,彈性球氣動球閥。不銹鋼氣動球閥,塑料氣動球閥,衛生級氣動球閥,碳鋼氣動球閥,二通氣動球閥,三通氣動球閥,四通氣動球閥。

                                                                                                                                  進口氣動球閥工作原理

                                                                                                                                  只需要用氣動執行器帶動閥體作90度的旋轉,就可以實現對介質的流量進行截斷和開通的功能。而且只需要很小的轉動力矩就能關閉嚴密。完全平等的閥體內腔為介質提供了一個阻力很小、并且直通的流道。通常認為球閥最適宜直接做開閉使用,現在已將球閥設計成使它具有節流和控制流量之用。球閥的主要特點是本身結構緊湊,易于操作和維修,適用于水、溶劑、酸和天然氣等一般工作介質,而且還適用于工作條件惡劣的介質,如氧氣、過氧化氫、甲烷和乙烯等。球閥閥體可以是整體的,也可以是組合式的。

                                                                                                                                  進口氣動球閥主要優點

                                                                                                                                  A、防靜電功能:在球體、閥桿、閥體之間設置彈簧,能將開關過程產生的靜電導出。

                                                                                                                                  B、閥桿密封可靠,由于閥桿只作彷轉動運而不做升降運動,閥桿的填料密封不易破壞,且密封能力隨著介質的壓力增高而增大;

                                                                                                                                  C、閥座密封性能好,采用聚四氟乙烯等彈性材料制成的密封圈,結構易于密封,而且球閥的閥封能力隨著介質壓力的增高而增大;

                                                                                                                                  D、止推軸承減小閥桿磨擦力矩,可使閥桿長期操作平穩靈活;

                                                                                                                                  E、由于聚四氟乙烯等材料具有良好的自潤滑性,與球體的磨擦損失小,故球閥的使用壽命長;

                                                                                                                                  F、下裝式閥桿和閥桿頭部凸階防止閥桿噴出,如火災造成閥桿密封破壞,凸階與閥體間還可形成金屬接觸,確保閥桿密封;

                                                                                                                                  G、流體阻力小、球閥是所有閥類中流體阻力最小的一種,即使是縮徑球閥,其流體阻力也相當小。氣動球閥主要用于截斷或接通管路中的介質,亦可用用于流體的調節與控制,在如上幾個方面與同類閥類相比之下,優點突出
