style="text-indent:25px">閥門安裝注意事項(xiàng)：1.閥門的閥體材料多用鑄鐵制作，性脆，故不得受重物撞擊。2.搬運(yùn)閥門時，不允許隨手拋擲；吊運(yùn)、吊裝閥門時，繩索應(yīng)系在閥體上，嚴(yán)禁拴在手輪、閥桿及法蘭螺栓孔上。3.閥門應(yīng)安裝在操作、維護(hù)和檢修較方便的地方，嚴(yán)禁埋于地下。直埋和地溝內(nèi)管道上的閥門，應(yīng)設(shè)檢查井室，以便于閥門的啟閉和調(diào)節(jié)。4.應(yīng)保證螺紋完整無損，并在螺紋上纏麻、抹鉛油或纏上聚四氟乙烯生料帶，旋扣時，需用扳手卡住擰入管子一端的六角閥體。5.安裝法蘭閥門時，注意沿對角線方向擰緊連接螺栓，擰動時用力要均勻，以防墊片跑偏或引起閥體變形與損壞。6.閥門在安裝時應(yīng)保持關(guān)閉狀態(tài)。對靠墻較近的螺紋閥門，安裝時常需要卸去閥桿閥瓣和手輪，才能擰轉(zhuǎn)。在拆卸時應(yīng)在擰動手輪使閥門保持開啟狀態(tài)后，再進(jìn)行拆卸。南昌閥門電裝廠家電話檢查閥座與閥體的結(jié)合是否牢固，閥瓣與閥座、閥蓋和閥體,閥桿與閥瓣的聯(lián)結(jié)。</p><div

style="text-indent:25px">名詞解釋：閥門的密封性能是指閥門各密封部位阻止介質(zhì)泄漏的能力，它是閥門較重要的技術(shù)性能指標(biāo)。閥門的密封部位有三處：啟閉件與閥座兩密封面間的接觸處；填料與閥桿和填料函的配和處；閥體與閥蓋的連接處。其中前一處的泄漏叫做內(nèi)漏，也就是通常所說的關(guān)不嚴(yán)，它將影響閥門截斷介質(zhì)的能力。對于截斷閥類來說，內(nèi)漏是不允許的。后兩處的泄漏叫做外漏，即介質(zhì)從閥內(nèi)泄漏到閥外。外漏會造成物料損失，污染環(huán)境，嚴(yán)重時還會造成事故。對于易燃易爆、有毒或有放射的介質(zhì)，外漏更是不能允許的，因而閥門必須具有可靠的密封性能。</p><p style="text-indent:25px">管道閥門的精髓：1.換向分流根據(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(dāng)?shù)叵嗷ミB接起來，也可作換向分流用。2.帶有懸浮顆粒的介質(zhì)當(dāng)介質(zhì)中帶有懸浮顆粒時，較適于采用其關(guān)閉件沿密封面的滑動帶有擦拭作用的閥門。如果關(guān)閉件對閥座的來回運(yùn)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。運(yùn)行中的閥門應(yīng)完好，法蘭和支架上的螺栓齊全，螺紋無損，沒有松動現(xiàn)象。</p><div

style="text-indent:25px">閥門安裝前檢查：1.仔細(xì)檢查核對閥門型號、規(guī)格是否符合圖紙要求。2.檢查閥桿和閥瓣開啟是否靈活，有無卡住和歪斜現(xiàn)象。3.檢查閥門有無損壞，螺紋閥門的螺紋是否端正和完整無缺。4.檢查閥座與閥體的結(jié)合是否牢固，閥瓣與閥座、閥蓋和閥體,閥桿與閥瓣的聯(lián)結(jié)。5.檢查閥門墊料、填料及緊固件(螺栓)是否適合于工作介質(zhì)性質(zhì)的要求。6.對陳舊的或擱置較久的減壓閥應(yīng)拆卸，灰塵、砂粒等雜物須用水清洗干凈。7.除去通口封蓋，檢查密封程度，閥瓣必須關(guān)閉嚴(yán)密。安裝螺紋閥門時，為便于拆卸，一個螺紋閥門應(yīng)配用一個活接?；罱拥脑O(shè)置應(yīng)考慮檢修的方便，通常是水流先經(jīng)閥門后流經(jīng)活接。注脂時，要注意閥體排污和絲堵泄壓問題。南昌閥門電裝廠家電話</p><p
