2、高溫、超高壓介質(zhì)的管路或裝置上宜選用高溫高壓截止閥，江蘇氣動截止閥。如火電廠、核電站，江蘇氣動截止閥，石油化工系統(tǒng)的高溫、高壓管路上。 3、有流量調(diào)節(jié)或壓力調(diào)節(jié)，對調(diào)節(jié)精度要求高，而且管路直徑又比較小，如公稱通經(jīng)≤50mm 的管路上，宜選用高溫高壓截止閥。 4、管路上對流阻要求嚴(yán)格的管路上。 5、城市建設(shè)中的供水、供熱工程上，公稱通經(jīng)常規(guī)與小口徑的管路。電站高溫高壓截止閥的5個選用原則是哪五個？江蘇氣動截止閥</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">電站截止閥的用途：1、為機(jī)組檢修提供安全工作條件。當(dāng)電站采用一根壓力管道向兩臺或兩臺以上機(jī)組供水的聯(lián)合或分組供水方式時，其中一臺機(jī)組檢修，可關(guān)閉它的主閥，從而在不影響其他機(jī)組運(yùn)行的前提下形成安全工作條件。2、停機(jī)時減少機(jī)組漏水量，開機(jī)時縮短啟動所需要的時間。水輪機(jī)的導(dǎo)水機(jī)構(gòu)往往關(guān)閉不嚴(yán)，在停機(jī)后存在較大的漏水量。這不僅浪費了水能，還會因漏水在縫隙處引起汽蝕破壞。據(jù)統(tǒng)計，一般導(dǎo)葉漏水量為水輪機(jī)較大流量的2%-5%左右，嚴(yán)重的可達(dá)8%，水頭較高的小型機(jī)組甚至因漏水量過大而不能停機(jī)。當(dāng)機(jī)組較長時間停機(jī)時，關(guān)閉其電站截止閥就可以減少漏水量。3、防止機(jī)組飛逸事故擴(kuò)大。當(dāng)機(jī)組或調(diào)速系統(tǒng)發(fā)生故障時，水輪機(jī)不能及時關(guān)閉可能會造成機(jī)組飛逸事故，此時轉(zhuǎn)速信號器應(yīng)自動發(fā)出指令緊急關(guān)閉水輪機(jī)主閥，快速切斷水流，防止機(jī)組飛逸，避免事故擴(kuò)大。如果沒有設(shè)置水輪機(jī)主閥，則應(yīng)快速關(guān)閉壓力管道進(jìn)水口閘門，但由于壓力管排空需要時間，機(jī)組飛逸時間會較長。江蘇氣動截止閥電站截止閥主要壓力等級：公稱壓力

style="text-indent:25px">電站截止閥的安裝工作注意事項有：1.安裝前須檢查閥門腔內(nèi)和密封面等部位，不允許有污物或砂粒附著。2.驅(qū)動裝置的接線須按線路圖進(jìn)行。3.用戶在安裝電站閘閥前，必須校對閥門型號，連接尺寸及注意介質(zhì)流向，保證與閥門要求一致性。4.檢查填料部位要求壓緊，既保證填料的密封性，也要保證閘板開啟靈活。5.各連接部位螺栓，要求均勻擰緊。6.用戶在安裝電站閘閥時，必須預(yù)留閥門驅(qū)動的必要空間。在進(jìn)行電站截止閥安裝的時候，需要做好安裝的小細(xì)節(jié)，從而確保其能正常的使用。</p><p

style="text-indent:25px">有哪些方法能提高電站截止閥的密封壽命呢?電站截止閥結(jié)構(gòu)簡樸，可通過閥桿既旋轉(zhuǎn)又升降的原理，達(dá)到閥門的開啟或截斷，并確保閥門的密封和上密封功能。因為該結(jié)構(gòu)特殊的運(yùn)動原理，也造成對閥門上密封副間受力極為不利的后果（形成既有密封副間必需的垂直壓力，又有密封副間相對滑移的摩擦）。實踐證明，閥門的上密封往往只啟閉幾回，就因為密封副間的擦傷而引起泄漏。擦傷輕微的需拆開修復(fù)，擦傷嚴(yán)峻的均因損壞而報廢，這樣的后果不但增加了企業(yè)的制造成本，而且影響閥門的機(jī)能。為解決此類標(biāo)題題目對閥門上密封的結(jié)構(gòu)和材料做了試驗和改進(jìn)。將閥桿的上密封部位移動到閥瓣上（目的是在受力過程中，使閥瓣上的上密封面相對閥蓋上的上密封面處于靜止無滑移狀態(tài)）。此改進(jìn)雖然可提高上密封的壽命，但因為要增加一道閥瓣蓋與閥瓣間的密封使得結(jié)構(gòu)較復(fù)雜，性價比較低。電站高壓閘閥跟電站高溫截止閥有哪些不同？江蘇氣動截止閥</p><p
