Q41F型球閥是浮動球球閥,浮動球球閥的結構簡單,密封性好,但球體承受工作介質(zhì)的載荷全部傳給了出口密封圈,因此要考慮密封圈材料能否經(jīng)受得住球體介質(zhì)的工作載荷,在受到較高壓力沖擊時,球體可能會發(fā)生偏移。這種結構,一般用于中低壓球閥。球閥在管路中主要用來做切斷、分配和改變介質(zhì)的流動方向。我公司球閥有如下優(yōu)點:
1.流體阻力小,全通徑的球閥基本沒有流阻。
2.結構簡單、體積小、重量輕。
3.緊密可靠。它有兩個密封面,而且目前球閥的密封面材料廣泛使用各種塑料,密封性好,能實現(xiàn)完全密封。在真空系統(tǒng)中也已廣泛使用。
4.操作方便,開閉迅速,從全開到全關只要旋轉90°,便于遠距離的控制。
5.維修方便,球閥結構簡單,密封圈一般都是活動的,拆卸更換都比較方便。
6.在全開或全閉時,球體和閥座的密封面與介質(zhì)隔離,介質(zhì)通過時,不會引起閥門密封面的侵蝕。
7.適用范圍廣,通徑從小到幾毫米,大到幾米,從高真空至高壓力都可應用。
8.由于球閥在啟閉過程中有擦拭性,所以可用于帶懸浮固體顆粒的介質(zhì)中。
