style="font-size:16px;">球閥安裝注意事項1，安裝前應(yīng)仔細(xì)查看閥門標(biāo)志、合格證等是否符合使用要求，帶驅(qū)動裝置的應(yīng)正確規(guī)范安裝。2，安裝前，閥門應(yīng)處于關(guān)閉狀態(tài)，避免雜質(zhì)進(jìn)入閥內(nèi)，損壞密封面。3，使用中，閥門至少應(yīng)保持每年一次的定期檢查、維護(hù)、保養(yǎng)，及時檢查問題，避免使用出現(xiàn)問題。安裝前的準(zhǔn)備1、球閥前后管線已準(zhǔn)備好。前后管道應(yīng)同軸，兩法蘭密封面應(yīng)平行。管道應(yīng)能承受球閥的重量，否則管道上必須配有適當(dāng)?shù)闹巍?、把閥前后管線吹掃干凈，清理掉管道內(nèi)的油污、焊渣和一切其它雜質(zhì)。3、核對球閥的標(biāo)志，查明球閥完好無損。將閥全開全閉數(shù)次證實其工作正常。4、拆去球閥兩端連接法蘭上的保護(hù)件。5、檢查閥孔清理可能有的污物，然后清洗閥孔。閥座與球之間即使*有微小顆粒的異物也可能會損傷閥座密封面</span><span style="font-size:16px;">。</span> </p><p> <span style="font-size:16px;">球閥的主要功能是切斷或接通管道中的流體通道。球閥的工作原理是借助驅(qū)動裝置在閥桿上端施加一定的轉(zhuǎn)矩傳給球體，使其旋轉(zhuǎn)90°，完成開啟或關(guān)閉閥門的動作。球閥閥座的密封原理依其結(jié)構(gòu)而異，常用的閥座結(jié)構(gòu)可分為固定閥座浮動球體與浮動閥座固定球體兩大類。當(dāng)閥座固定球體浮動時，在流體壓力作用下球體在流體流動方向產(chǎn)生位移，使它與閥后閥座密封而更緊密地接觸，即在該密封面上的比壓增大，形成單面密封，同時，閥前閥座密封面上的比壓相應(yīng)減小，往往不保證密封。當(dāng)閥座浮動球體固定時，流體壓力不能使球體產(chǎn)生位移，而是閥座借助于彈簧或流體推力壓向球體，建立密封比壓。普通閥座的特點是在預(yù)緊力或流體壓力作用下閥座與球體壓緊，并使閥座材料產(chǎn)生彈塑性變形而達(dá)到密封，其密封效果取決于閥座在流體壓力或預(yù)緊力的作用下補(bǔ)償球體圓度和表面微觀不平度的能力。因此，閥座與球體之間必須具有足夠大的密封比壓。</span> 球閥的一大優(yōu)點是閥門全開時通過閥門的流體壓降很小，幾乎不受阻礙。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="高臺球閥哪個好,球閥"
