style="text-indent:25px">止回閥包括旋啟式止回閥和升降式止回閥。旋啟式止回閥有一介鉸鏈機構(gòu),還有一個像門一樣的閥瓣自由地靠在傾斜的閥座表面上。為了確保閥瓣每次都能到達閥座面的合適位置,閥瓣設(shè)計在鉸鏈機構(gòu),以便閥瓣具有足夠有旋啟空間,并使閥瓣真正的與閥座接觸。閥瓣可以全部用金屬制成,也可以在金屬上鑲嵌皮革、橡膠、或者采用合成覆蓋面,這取決于使用性能的要求。旋啟式止回閥在完全打開的狀況體壓力幾乎不受阻礙,因此通過閥門的壓力降相對較小。升降式止回閥的閥瓣座落位于閥體上閥座密封面上。此閥門除了閥瓣可以自由地升降之外,其余部分如同截止閥一樣,流體壓力使閥瓣從閥座密封面上抬起,介質(zhì)回流導(dǎo)致閥瓣回落到閥座上,并切斷流動。</p><p style="text-indent:25px">電站止回閥的清理檢查：檢查閥芯及閥體上的閥線，閥線上應(yīng)無影響密封性能的凹槽、氣孔及橫貫密封面的痕跡，應(yīng)全周接觸無間斷。若發(fā)現(xiàn)有影響密封性能的缺陷應(yīng)進行研磨等處理。檢查閥蝶與搖臂間的連接情況，調(diào)整墊片與搖臂間隙為1～1.2mm之間，不應(yīng)過大也不應(yīng)過小，否則應(yīng)進行調(diào)整。閥蝶與搖臂的緊固螺母連接應(yīng)牢固，定位的焊點應(yīng)完整、無裂紋，閥蝶軸與搖臂圈的間隙應(yīng)符合要求。檢查杠桿軸、搖臂軸與大小襯套及播臂的間隙應(yīng)符合要求，各軸表面及襯套內(nèi)壁表面應(yīng)光潔、無凹坑。電站止回閥在管線中不要使止回閥承受重量，大型的止回閥應(yīng)**支撐，使之不受管系產(chǎn)生的壓力的影響。</p><div

②介質(zhì)倒流。引起閥瓣打碎的原因是:止回閥前后介質(zhì)壓力處于接近的平衡而又互相“拉鋸”的狀態(tài)，閥瓣經(jīng)常與閥座拍打，某些脆性材料（如鑄鐵、黃銅等）做成的閥瓣就被打碎。預(yù)防的辦法是采用閥瓣為韌性材料的止回閥。介質(zhì)倒流的原因有:①密封面破壞；②夾入雜質(zhì)。修復(fù)密封面和清洗雜質(zhì)，就能防止倒流。雙旋啟動式止回閥止回閥用途及特性:旋啟式止回閥的功能是用來防止管路中的介質(zhì)倒流。止回閥屬于自動閥類，啟閉件靠流動介質(zhì)的力量自行開啟或關(guān)閉。止回閥只用于介質(zhì)單向流動的管路上，阻止介質(zhì)回流，以防發(fā)生事故。美標止回閥的閥瓣為旋啟式，流道為直通式，水平管道、垂直管道均可安裝。河南高溫高壓電站止回閥廠家</p><p

style="text-indent:25px">止回閥的安裝應(yīng)注意以下事頂：1、在管線中不要使止回閥承受重量，大型的止回閥應(yīng)**支撐，使之不受管系產(chǎn)生的壓力的影響。2、安裝時注意介質(zhì)流動的方向應(yīng)與閥體所票箭頭方向一致。3、升降式垂直瓣止回閥應(yīng)安裝在垂直管道上。4、升降式水平瓣止回閥應(yīng)安裝在水平管道上。當介質(zhì)按規(guī)定方向流動時，閥瓣受介質(zhì)力的作用，被開啟;介質(zhì)逆流時，因閥瓣自重和閥瓣受介質(zhì)反向力的作用，使閥瓣與閥座的密封面密合而關(guān)閉，達到阻止介質(zhì)逆流的目的。閥體及閥瓣的密封面采用不銹鋼堆焊。徐州鑄造電站止回閥廠家</p><p
