不鏽鋼美(měi)标球閥優點

1.流體阻力小,全通徑的球閥基本沒有流(liú)阻。
2.結構簡單、體積(jī)小、重量輕。
3.緊密可靠(kào)。它有兩個密封面,而且目前球閥(fá)的密封面材料廣(guǎng)泛使用各種塑(sù)料,密封性好,能實現完全密封。在真空(kōng)系統中也已(yǐ)廣泛(fàn)使用。
4.操作方便,開閉迅速,從全開到全關隻要旋轉(zhuǎn)90°,便于遠距離(lí)的控制(zhì)。
5.維修方便,球閥結構簡單,密封圈一般都(dōu)是活動的,拆卸更換(huàn)都比較(jiào)方便。
6.在全開或全閉時,球體和閥座的密封面與介質隔離,介質通過時,不會引起閥(fá)門密封面的侵蝕(shí)。
7.适用範圍廣,通徑從小到幾毫米,大到幾米(mǐ),從高真空(kōng)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(yǐ)可用于帶懸浮固(gù)體(tǐ)顆粒的介質中。
