氣動球閥的優點

發布日期:2017-12-14 作者: 點擊:

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,它與其它閥類相比的優點:

1、流體阻力小、球閥是所有閥類中流體阻力小的一種,即使是縮徑球閥,其流體阻力也相當小。球閥供應商

2、止推軸承減小閥杆磨擦力矩,可使閥杆長期操作平穩靈活。

3、氣動球閥座密封性能好,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随着介質壓力的增高而增大。

4、氣動球閥杆密封可靠,由于閥杆隻作彷轉動運而不做升降運動,閥杆的填料密封不易破壞,且密封能力随着介質的壓力增高而增大。

5、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。

6、下裝式閥杆和閥杆頭部凸階防止閥杆噴出,如火災造成閥杆密封破壞,凸階與閥體間還可形成金屬接觸,确保閥杆密封。

7、氣動球閥防靜電功能:在球體、閥杆、閥體之間設置彈簧,能将開關過程産生的靜電導出,執行機構。
