style="text-indent:25px">采用金屬密封的閥門一般比彈性密封的閥門壽命長，但很難做到完全密封。金屬密封能適應(yīng)較高的工作溫度，彈性密封則具有受溫度限制的缺陷。如果要求蝶閥作為流量控制使用，主要的是正確選擇閥門的尺寸和類型。蝶閥的結(jié)構(gòu)原理尤其適合制作大口徑閥門。蝶閥不僅在石油、煤氣、化工、水處理等一般工業(yè)上得到普遍應(yīng)用，而且還應(yīng)用于熱電站的冷卻水系統(tǒng)。常用的蝶閥有對夾式蝶閥和法蘭式蝶閥兩種。對夾式蝶閥是用雙頭螺栓將閥門連接在兩管道法蘭之間，法蘭式蝶閥是閥門上帶有法蘭，用螺栓將閥門上兩端法蘭連接在管道法蘭上。</p><p style="text-indent:25px">手動高真空蝶閥密封材料選用丁腈橡膠，可用于介質(zhì)溫度在-25~80℃的高真空系統(tǒng)中，選用氟橡膠密封圈，可用于烘烤溫度150℃的超高真空系統(tǒng)中。手動高真空蝶閥的工作原理是靠固定在轉(zhuǎn)動軸上的閥板旋轉(zhuǎn)90°實現(xiàn)閥門的開啟和關(guān)閉，和其他相同口徑的真空閥門相比，具有結(jié)構(gòu)簡單，通導(dǎo)能力大，閥體厚度小，啟閉速度快等優(yōu)點。上海卓帕真空技術(shù)有限公司生產(chǎn)的高真空手動蝶閥有手動、電動、氣動等三種形式。對于手動高真空蝶閥的缺點就是在使用壓力和工作溫度范圍比較小，尤其在安裝時，閥瓣要停在關(guān)閉的位置上，開啟位置應(yīng)按蝶板的旋轉(zhuǎn)角度來確定，帶有旁通閥的真空蝶閥,開啟前應(yīng)先打開旁通閥，然后才能正常使用。超高真空閥門要加強超高真空閥門的研制和開發(fā)。</p><div

style="text-indent:25px">如何正確地選用各種真空閥門？蝶閥的介紹及選型：蝶閥的蝶板安裝于管道的直徑方向。在蝶閥閥體圓柱形通道內(nèi)，圓盤形蝶板繞著軸線旋轉(zhuǎn)，旋轉(zhuǎn)角度為0°~90°之間，旋轉(zhuǎn)到90°時，閥門則牌全開狀態(tài)。蝶閥結(jié)構(gòu)簡單、體積小、重量輕，只由少數(shù)幾個零件組成。而且只需旋轉(zhuǎn)90°即可快速啟閉，操作簡單，同時該閥門具有良好的流體控制特性。蝶閥處于完全開啟位置時，蝶板厚度是介質(zhì)流經(jīng)閥體時的阻力，因此通過該閥門所產(chǎn)生的壓力降很小，故具有較好的流量控制特性。蝶閥有彈密封和金屬的密封兩種密封型式。彈性密封閥門，密封圈可以鑲嵌在閥體上或附在蝶板周邊。真空閥門是真空系統(tǒng)中用以調(diào)節(jié)氣流量、切斷或接通管路的元件。GU型-手動高真空球閥生產(chǎn)商</p><p

style="text-indent:25px">真空閥門應(yīng)注意的防凍工作:一、學(xué)習(xí)防寒防凍內(nèi)容，在秋天的時候要對各類真空閥門做大檢查，對管道的防寒防凍工作進行檢查。二、防凍還要分地域，北方和南方差別不小，針對冬季特點，要結(jié)合本單位實際，制定冬季鍋爐、壓力容器、壓力管道及其附屬閥門、泄放裝置防凍措施，并將措施落實到實處；對易造成凍裂的部位，加大日常巡查力度。密切關(guān)注突發(fā)的大幅度降溫天氣，提前采取保溫及應(yīng)對措施。利用保溫材料加強裝置保溫。三、停用或者檢修完設(shè)備內(nèi)的水放凈，以免凍裂；介質(zhì)中可能含水壓力容器,要定期放水，同時放水閥門注意保溫；水蒸汽管道檢查疏水情況，同時要對疏水閥門及管道作好保溫；化工系統(tǒng)的倒淋管道需要保溫；鍋爐、壓力容器、壓力管道上的閥需保溫，以免被凍住，造成失靈；在做水壓試驗時，注意保暖，特別較細管道的防凍問題；在環(huán)境溫度低時易結(jié)凍的壓力容器上液位計或者壓力管道加裝蒸汽伴管，注意蒸汽的暢通。GU型-手動高真空球閥生產(chǎn)商</p><p
