不銹鋼美標(biāo)球閥優(yōu)點
1．流體阻力小，全通徑的球閥基本沒有流阻。
2．結(jié)構(gòu)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(guān)只要旋轉(zhuǎn)90°，便于遠距離的控制。
5．維修方便，球閥結(jié)構(gòu)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，從高真空到高壓力都可應(yīng)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。
