style="text-indent:25px">不銹鋼美標止回閥是指閥瓣依靠管路中介質(zhì)本身流動產(chǎn)生的力而自動開啟、關(guān)閉，屬于自動類閥門，又稱逆止閥、單向閥、逆流閥、和背壓閥。用途：不銹鋼美標止回閥其主要作用是防止介質(zhì)倒流、防止泵及驅(qū)動電動機反轉(zhuǎn)，以及容器介質(zhì)的泄放，還可用于給其中的壓力可能升至超過系統(tǒng)壓的輔助系統(tǒng)提供補給的管路上。根據(jù)閥體及內(nèi)件材質(zhì)的不同，可適用在化工、石油、發(fā)電、水處理、環(huán)保等工業(yè)系統(tǒng)需防止介質(zhì)逆向流動管道中。特點：1.實心銷軸安裝精確，強度高，保證了閥門的使用性能和使用壽命； 2.搖桿具有足夠的強度，關(guān)閉時有足夠的自由度以利于閥瓣關(guān)閉； 3.大口徑的止回閥設(shè)計有吊環(huán)，方便起吊、方便安裝； 4.閥瓣限位裝置，防止閥瓣打開位置過高而無法關(guān)閉； 5.閥瓣的精確設(shè)計與強度，保證了閥門的密封性。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。溫州自密封電站止回閥廠家</p><p style="text-indent:25px">單瓣旋啟式止回閥一般適用于中等口徑的場合。溫州自密封電站止回閥廠家</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。溫州自密封電站止回閥廠家</p><p
