style="text-indent:25px">閥門注脂時的維護(hù)保養(yǎng)工作：1、閥門注脂時，注意閥門在開關(guān)位的問題。球閥維護(hù)保養(yǎng)時一般都處于開位狀態(tài)，特殊情況下選擇關(guān)閉保養(yǎng)，江西閥門電裝銷售廠家。其他閥門也不能一概以開位論處。閘閥在養(yǎng)護(hù)時則必須處于關(guān)閉狀態(tài)，確保潤滑脂沿密封圈充滿密封槽溝，如果開位，密封脂則直接掉入流道或閥腔，造成浪費(fèi)。2、閥門注脂時，常忽略注脂效果問題。注脂操作中壓力、注脂量、開關(guān)位都正常。但為確保閥門注脂效果，有時需開啟或關(guān)閉閥門，對潤滑效果進(jìn)行檢查，確認(rèn)閥門閥球或閘板表面潤滑均勻。3、注脂時，要注意閥體排污和絲堵泄壓問題，江西閥門電裝銷售廠家，江西閥門電裝銷售廠家。閥門打壓試驗(yàn)后，密封腔閥腔內(nèi)氣體和水分因環(huán)境溫度升高而升壓，注脂時要先進(jìn)行排污泄壓，以利于注脂工作的順利進(jìn)行。注脂后密封腔內(nèi)的空氣和水分被充分置換出來。及時泄掉閥腔壓力，也保障了閥門使用安全。注脂結(jié)束后，一定要擰緊排污和泄壓絲堵，以防意外發(fā)生。球閥和旋塞閥在啟閉過程中對密封面均有擦拭作用，故適宜用在帶有懸浮顆粒的介質(zhì)中。江西閥門電裝銷售廠家</p><div

style="text-indent:25px">安全閥工作原理：安全閥在系統(tǒng)中起安全保護(hù)作用，安全閥的啟閉件受外力作用下處于常閉狀態(tài)，當(dāng)設(shè)備或管道內(nèi)的介質(zhì)壓力升高超過規(guī)定值時，通過向系統(tǒng)外排放介質(zhì)來防止管道或設(shè)備內(nèi)介質(zhì)壓力超過規(guī)定數(shù)值。安全閥作用安全閥屬于自動閥類，主要用于鍋爐、壓力容器和管道上，控制壓力不超過規(guī)定值，對人身安全和設(shè)備運(yùn)行起重要保護(hù)作用。注安全閥必須經(jīng)過壓力試驗(yàn)才能使用。試壓方法：安全閥的強(qiáng)度試驗(yàn)與其他閥門一樣，是用水作試驗(yàn)的。試驗(yàn)閥體下部時，壓力從進(jìn)I=I端引入，密封面封閉；試驗(yàn)閥體上部和閥蓋時，壓力從出El端引入，其他端封閉。在規(guī)定時間內(nèi)閥體和閥蓋無滲漏現(xiàn)象為合格。密封性試驗(yàn)和定壓試驗(yàn)，一般使用介質(zhì)是：蒸汽用安全閥以飽和蒸汽為試驗(yàn)介質(zhì)；氨或其他氣體用閥以空氣為試驗(yàn)介質(zhì)；水和其他非腐蝕性液體用閥以水為試驗(yàn)介質(zhì)。對于一些重要位置的安全閥常用氮?dú)鉃樵囼?yàn)介質(zhì)。密封試驗(yàn)以公稱壓力值為試驗(yàn)壓力進(jìn)行試驗(yàn)，其次數(shù)不少于兩次，在規(guī)定時間內(nèi)無滲漏為合格。甌北閥門裝配用工具必須在裝配前進(jìn)行脫脂清洗，保證潔凈。</p><div

style="text-indent:25px">我國閥門行業(yè)發(fā)展現(xiàn)狀概述：中國的閥門業(yè)經(jīng)過幾十年的發(fā)展后,已經(jīng)取得了很大的進(jìn)步,目前的閥門行業(yè)產(chǎn)品的使用其性能參數(shù)范圍從真空閥門到600 MPa的超高壓閥門,溫度從深冷-196℃到高溫570℃。使用介質(zhì)為水、蒸汽、尿素、乙烯、易爆等介質(zhì)。閥門是利潤率低的產(chǎn)品,市場競爭非常激烈。閥門在水處理行業(yè)中使用量大,主要以低壓閥門產(chǎn)品為主,如蝶閥、閘閥、止回閥。據(jù)了解,目前市場上具有一定規(guī)模的閥門企業(yè)有2000余家,大多數(shù)分布在江浙及中原一帶。目前我國在閥門市場中，已經(jīng)能夠提供多種產(chǎn)品：例如供熱閥，環(huán)保用閥、建筑用閥門等等。盡管近些年通過國內(nèi)企業(yè)的努力，一些中較高泵閥產(chǎn)品已經(jīng)實(shí)現(xiàn)了國產(chǎn)化，但是仍有一些產(chǎn)品處于進(jìn)口狀態(tài)。據(jù)我國通用機(jī)械工業(yè)協(xié)會提供的數(shù)據(jù)，2013年以來我國進(jìn)口量較大的泵產(chǎn)品主要包括：液壓往復(fù)式柱塞泵，其它液壓往復(fù)式排液泵，回轉(zhuǎn)式軸向柱塞泵，轉(zhuǎn)速在10000轉(zhuǎn)/分以下的其它離心泵、液體泵零件、真空泵等。閥門產(chǎn)品主要包括：減壓閥、油壓傳動閥、氣壓傳動閥、安全閥或溢流閥、閥門零件等。在高壓閥門領(lǐng)域仍然依賴進(jìn)口，這也是我國閥門需要突破的領(lǐng)域。閥門可以對這些變化進(jìn)行連續(xù)或重復(fù)的操作。</p><div

style="text-indent:25px">閥門注脂時的維護(hù)保養(yǎng)工作：閥門注脂時，常忽略壓力問題。在注脂操作時，注脂壓力有規(guī)律地呈峰谷變化。壓力過低，密封漏或失效，壓力過高，注脂口堵塞、密封內(nèi)脂類硬化或密封圈與閥球、閥板抱死。通常注脂壓力過低時，注入的潤滑脂多流入閥腔底部，一般發(fā)生在小型閘閥。而注脂壓力過高，一方面檢查注脂嘴，如是脂孔阻塞判明情況進(jìn)行更換；另一方面是脂類硬化，要使用清洗液，反復(fù)軟化失效的密封脂，并注入新的潤滑脂置換。此外，密封型號和密封材質(zhì)，也影響注脂壓力，不同的密封形式有不同的注脂壓力，一般情況硬密封注脂壓力要高于軟密封。運(yùn)輸過程中要采取措施保證包封不破損。江西閥門電裝銷售廠家</p><p
