style="font-size:16px;">大型閥門的設置要求大型閥門的操作應使用帶齒輪傳動機構(gòu)，設置時應考慮傳動機構(gòu)所需空間位置。通常，閥門的尺寸大于下列等級的尺寸應考慮使用帶齒輪傳動機構(gòu)的閥門。大型閥門應在閥門的一側(cè)或兩側(cè)設置支架，該支架不應設在檢修時需要拆卸的短管上，并考慮拆下閥門時不應影響管道的支承。一般支架與閥門法蘭的距離應大于300mm。大型閥門的安裝位置要有使用吊車的場地，或考慮設吊柱、吊梁。4水平管道上閥門的設置要求除工藝另有特殊要求外，一般水平管道上安裝的閥門手輪不得朝下，尤其是危險介質(zhì)管道上的閥門嚴禁手輪朝下。閥門手輪的方位按下列順序確定：垂直向上；水平；垂直向上的左、右傾斜45°；垂直向下的左、右傾斜45°；不得垂直向下。水平安裝的明桿式閥門，當閥門開啟時，閥</span><span

style="font-size:16px;">閥門的布置原則閥門應根據(jù)管道及儀表流程圖（PID）上所示類型及數(shù)量設置。當PID對某些閥門的安裝位置有具體要求時，應按工藝要求設置。閥門應布置在容易接近、便于操作、維修的地方。成排管道上的閥門應集中布置，并考慮設置操作平臺或梯子。閥門的安裝位置要求閥門應布置在容易接近進出裝置的管廊管道在與全廠管廊上的主管相接時，均須設置切斷用閥門。閥門的安裝位置應集中布置在裝置區(qū)一側(cè)，并設置必要的操作平臺或檢修平臺。需要經(jīng)常操作、維修和更換的閥門，應位于地面、平臺或梯子容易接近處。氣動和電動閥也同樣</span><span style="font-size:16px;">應布置在容易接近處。不需要經(jīng)常操作的閥門（只在開停車時使用），如果在地面上無法操作時，也應布置在能架設臨時梯子的地方。</span> </p><p> <span style="font-size:16px;">在流體管道系統(tǒng)中，閥門是控制元件，其主要作用是隔離設備和管道系統(tǒng)、調(diào)節(jié)流量、防止回流、調(diào)節(jié)和排泄壓力。閥門可用于控制空氣、水、蒸汽、各種腐蝕性介質(zhì)、泥漿、油品、液態(tài)金屬和放射性介質(zhì)等各種類型流體的流動。由于管道系統(tǒng)選擇適合的閥門顯得非常重要，所以，了解閥門的特性及選擇閥門的步驟和依據(jù)也變得至關重要起來。閥門總的可分兩大類：自動閥門依靠介質(zhì)（液體、氣體）本身的能力而自行動作的閥門。如止回閥、安全閥、調(diào)節(jié)閥、疏水閥、減壓閥等。驅(qū)動閥門借助手動、電動、液動、氣動來操縱動作的閥門。如閘閥，截止閥、節(jié)流閥、蝶閥、球閥、旋塞閥等。使用特性它確定了閥門的主要使用性能和使用范圍，屬于閥門使用特性的有：閥門的類別（閉路閥門、調(diào)節(jié)閥門、安全閥門等）；產(chǎn)品類型（閘閥、截止閥、蝶閥、球閥等）；閥門主要零件（閥體、閥蓋、閥桿、閥瓣、密封面）的材料；閥門傳動方式等。</span> 閥門的材料應用是否得當，直接影響閥門的使用壽命和生產(chǎn)的安全運行。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="慶陽閥門哪家好,閥門"

style="font-size:16px;">換向分流用的閥門根據(jù)換向分流的需要，這種閥門可有三個或更多的通道。旋塞閥和球閥較適用于這一目的，因此，大部分用于換向分流的閥門都選取這類閥門中的一種。但是在有些情況下，其他類型的閥門，只要把兩個或更多個閥門適當?shù)叵嗷ミB接起來，也可作換向分流用。帶有懸浮顆粒的介質(zhì)用閥門當介質(zhì)中帶有懸浮顆粒時，適于采用其關閉件沿密封面的滑動帶有擦拭作用的閥門。如果關閉件對閥座的來回運動是豎直的，那末就可能夾持顆粒，因此這種閥門除非密封面材料可以允許嵌入顆粒，否則只適用于基本清潔的介質(zhì)。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。閥門應用、操作頻率和服務千變?nèi)f化，要控制或杜絕那怕是低微的泄漏，關鍵的設備還數(shù)閥門。學會正確選</span><span
