style="text-indent:25px">在進(jìn)行電站截止閥操作時(shí)要注意什么呢?對于截止閥，不但要會安裝和維護(hù)，而且還要會操作。電站截止閥，用力應(yīng)該平穩(wěn)，不可沖擊。某些沖擊啟閉的高壓截止閥各部件已經(jīng)考慮了這種沖擊力與一般截止閥不能等岡。當(dāng)截止閥全開后，應(yīng)將手輪倒轉(zhuǎn)少許，使螺紋之間綦嚴(yán)，以免松動損傷。管路初用時(shí)，內(nèi)部臟物較多，可將截止閥微啟，利用介質(zhì)的高速活動，將其沖走，然后輕輕封閉（不能快閉、猛閉，以防殘留雜質(zhì)夾傷密封面），再次開啟，如斯重復(fù)多次，沖凈臟物，再投入正常工作。電站截止閥，密封面上可能粘有臟物，封閉時(shí)也要用上述方法將其沖洗干凈，然后正式關(guān)嚴(yán)。如手輪、手柄損壞或丟失，應(yīng)立刻配齊，不可用活絡(luò)板手代替，以免損壞閥桿四方，啟閉不靈，以致在出產(chǎn)中發(fā)生事故。某些介質(zhì)，在截止閥封閉后冷卻，使閥件收縮，操作職員就應(yīng)于適當(dāng)時(shí)間再封閉一次，讓密封面不留細(xì)縫，否則，介質(zhì)從細(xì)縫高速流過，很輕易沖蝕密封面。操作時(shí)，如發(fā)現(xiàn)操作過于費(fèi)勁，應(yīng)分析原因。若填料太緊，可適當(dāng)放松，如閥桿歪斜，應(yīng)通知職員修理。有的截止閥，在封閉狀態(tài)時(shí)，封閉件受熱膨脹，造成開啟難題；如必需在此時(shí)開啟，可將閥蓋螺紋擰松半圈至一圈，消除閥桿應(yīng)力，然后板動手輪。電站焊接截止閥在額定工作范圍內(nèi)，始終保持流體的暢通。江蘇300lb美標(biāo)截止閥廠家</p><p style="text-indent:25px">電站焊接截止閥有非常可靠的切斷動作。江蘇300lb美標(biāo)截止閥廠家</p><p style="text-indent:25px">電站截止閥的優(yōu)點(diǎn)： 1.電站截止閥流體阻力小，其阻力系數(shù)與同長度的管段相等。 2.電站截止閥結(jié)構(gòu)簡單、體積小、重量輕。 3.電站截止閥緊密可靠，閘閥的密封面材料基本上使用的是塑料、密封性能好，其在真空系統(tǒng)得到大范圍的使用。 4.電站截止閥操作方便，開閉迅速，從全開到全關(guān)只要旋轉(zhuǎn)90度，便于遠(yuǎn)距離的控制。 5.電站截止閥維修方便，閘閥結(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.電站截止閥現(xiàn)在若是在全開或是全閉的狀況下，閥座密封面同球體會與介質(zhì)相隔離，這時(shí)，介質(zhì)通過時(shí)就不會引起閥門密封面的侵蝕。 7.電站截止閥適用范圍廣，通徑從小到幾毫米，大到幾米，從高真空至高壓力都可應(yīng)用。江蘇300lb美標(biāo)截止閥廠家</p><p
