style="text-indent:25px">鉻鉬鋼閘閥的原理: 電動(dòng)閥通常由電動(dòng)執(zhí)行機(jī)構(gòu)和閥門連接起來，經(jīng)過安裝調(diào)試后成為電動(dòng)閥。電動(dòng)閥使用電能作為動(dòng)力來接通電動(dòng)執(zhí)行機(jī)構(gòu)驅(qū)動(dòng)閥門，實(shí)現(xiàn)閥門的開關(guān)、調(diào)節(jié)動(dòng)作。從而達(dá)到對(duì)管道介質(zhì)的開關(guān)或是調(diào)節(jié)目的。鉻鉬鋼閘閥的特點(diǎn)： 1、結(jié)構(gòu)緊湊、設(shè)計(jì)合理、閥門剛性好，通道流暢，流阻系數(shù)小。 2、密封面采用不銹鋼和硬質(zhì)合金，使用壽命長。 3、采用柔性石墨填料板、密封可靠、操作輕便靈活。 4、驅(qū)動(dòng)方式分手動(dòng)、電動(dòng)、氣動(dòng)、齒輪傳動(dòng)、結(jié)構(gòu)形式；彈性楔式單閥、剛性楔式單閥板和雙閘板型式。 5、普遍適用于石油、化工、火力發(fā)電廠等油品、水、蒸汽管路上作接通或截?cái)喙苈分薪橘|(zhì)的啟閉裝置。 6、截止閥開閉較省力。 7、截止閥介質(zhì)流向不受限制,不擾流、不降低壓力</p><p style="text-indent:25px">法蘭閘閥生產(chǎn)廠家電動(dòng)閥過去對(duì)電機(jī)進(jìn)行維護(hù)的辦法是運(yùn)用熔斷器、過流繼電器、熱繼電器、恒溫器等，但這些辦法各有利弊。對(duì)電動(dòng)設(shè)備這種變負(fù)荷設(shè)備，可靠的維護(hù)辦法是沒有的。因而，有必要采納各種組合辦法，歸納起來有兩種：一是對(duì)電機(jī)輸入電流的增減進(jìn)行判別；二是對(duì)電機(jī)自身發(fā)熱情況進(jìn)行判別。這兩種辦法，無論那種都要考慮電機(jī)熱容量給定的時(shí)間余量。一般，過負(fù)荷的根本維護(hù)辦法是：對(duì)電機(jī)連續(xù)運(yùn)轉(zhuǎn)或點(diǎn)動(dòng)操作的過負(fù)荷維護(hù)，選用恒溫器；對(duì)電機(jī)堵轉(zhuǎn)的維護(hù)，選用熱繼電器；對(duì)于短路的危險(xiǎn)，選用熔斷器或過流繼電器。電站匣閥啟閉時(shí)間長，高度大由于閘閥啟閉時(shí)須全開或全關(guān)，閘板行程大，開啟用要一定的空間。</p><div

style="text-indent:25px">電站閥門的使用要求是：性能好可靠、強(qiáng)度高安全、操作方便靈活、維修簡單。在熱力系統(tǒng)中我們常常遇到由于一個(gè)閥門發(fā)生故障造成整個(gè)系統(tǒng)或整個(gè)機(jī)組停止運(yùn)行。尤其是母管制機(jī)組，常常因一個(gè)閥門不嚴(yán)密而無法消缺，給企業(yè)帶來不可挽回的損失。同時(shí)閥門的檢修質(zhì)量也是降低發(fā)電成本，提高機(jī)組熱效率，節(jié)能降耗的重要工作。要重視閥門的檢修質(zhì)量工作。閘閥：是作為截?cái)嘟橘|(zhì)使用，在全開時(shí)整個(gè)流通直通，此時(shí)介質(zhì)運(yùn)行的壓力損失較小。閘閥通常適用于不需要經(jīng)常啟閉，而且保持閘板全開或全閉的工況。不適用于作為調(diào)節(jié)或節(jié)流使用。對(duì)于高速流動(dòng)的介質(zhì)，閘板在局部開啟狀況下可以引起閘門的振動(dòng)，而振動(dòng)又可能損傷閘板和閥座的密封面，而節(jié)流會(huì)使閘板遭受介質(zhì)的沖蝕。電站閘閥的閘板是垂直置于閥體內(nèi)的，而截止閥閥瓣是水平置于閥體內(nèi)的，因而結(jié)構(gòu)長度比截止閥短。山東美標(biāo)電站閘閥生產(chǎn)廠家</p><p
