style="text-indent:25px">氣動閥門的日常維護：閥體(包括變速傳動箱體)內(nèi)外，首先應拋丸清砂除銹，力求靜電噴涂粉狀無毒環(huán)氧樹脂，厚度達0.3mm以上。特大型閥門靜電噴涂無毒環(huán)氧樹脂有困難時，亦應刷涂、噴涂相似的無毒環(huán)氧漆。閥體內(nèi)部以及閥板各個部位要求各方面防腐，一方面浸泡在水中不會銹蝕，在兩種金屬之間不產(chǎn)生電化學腐蝕；二方面表面光滑使過水阻力減少。閥體內(nèi)防腐的環(huán)氧樹脂或油漆的衛(wèi)生要求，應有相關機關的檢測報告?；瘜W物理性能亦應符合相關要求。</p><p style="text-indent:25px">可用于低壓管道介質(zhì)的開關控制。蝶閥是指關閉件（閥瓣或蝶板）為圓盤，圍繞閥軸旋轉來達到開啟與關閉的一種閥，在管道上主要起切斷和節(jié)流作用。蝶閥啟閉件是一個圓盤形的蝶板，在閥體內(nèi)繞其自身的軸線旋轉，從而達到啟閉或調(diào)節(jié)的目的。蝶閥適用于發(fā)生爐、煤氣、天然氣、液化石油氣、城市煤氣、冷熱空氣、化工冶煉和發(fā)電環(huán)保等工程系統(tǒng)中輸送各種腐蝕性、非腐蝕性流體介質(zhì)的管道上，用于調(diào)節(jié)和截斷介質(zhì)的流動。氣動蝶閥是由氣動執(zhí)行器和蝶閥組成。氣動蝶閥是用隨閥桿轉動的圓形蝶板做啟閉性，以實現(xiàn)啟用動作的氣動閥門主要做截斷閥使用，亦可設計成具有調(diào)節(jié)或段閥兼調(diào)節(jié)的功能，目前蝶閥在低壓大中口徑管道上的使用越來越多。氣動蝶閥分類：不銹鋼氣動蝶閥，硬密封氣動蝶閥，軟密封氣動蝶閥，碳鋼氣動蝶閥。氣動閥門公稱直徑不是外徑，也不是內(nèi)徑，而是近似普通鋼管內(nèi)徑的一個名義尺寸。</p><div

style="text-indent:25px">氣動閥門只有在運行動作正常的條件下，才能安裝使用。氣動閥的安裝要盡可能使閥門與管路法蘭同心，并加支撐固定。不能使球閥受其它外力作用，以免損壞閥門的中密封及閥門變形。造成閥門開關不靈及閥門的損壞而無法使用。要保證氣球閥及氣動元件所提供的動力氣源必須是潔凈，盡可能不帶油污及水。清潔度應小于0.4微米。接入氣源之前，必須清潔供氣管路，氣源接口和開關等器件，以防由于管路不清潔帶上污物和泥沙沖入氣動執(zhí)行單元而造成故障。氣動執(zhí)行器、電磁閥、定位器、過濾器、減壓閥等的連接，可用銅管或尼龍管，為以防防塵及減小噪聲，排氣口應安裝消聲器或消聲節(jié)流閥。氣動球閥的優(yōu)點是什么？上海船用閥門氣動制造</p><p style="text-indent:25px">氣動閥門在開啟狀況下，閥體應承受閥門工壓值二倍的內(nèi)壓檢測。上海船用閥門氣動制造</p><p style="text-indent:25px">控制柜發(fā)送信號閥門不動作，經(jīng)現(xiàn)場觀察氣動調(diào)節(jié)蝶閥在安裝定位器的前提下又加裝了電磁閥，電磁閥的強電干擾到了控制柜的信號輸出，閥門接收不到信號，故不能正常工作。解決辦法：拆除電磁閥，去掉強電干擾設備正常運行（注：電磁閥的功能是起到閥門的開關作用，定位器的作用是用4到20 毫安信號控制閥門的開度，所以在裝有定位器的前提下沒有必要安裝電磁閥）。自動切換成手動狀態(tài)以后，切換不回自動；由于現(xiàn)場操作員使用力道過大離合器扳動幅度過大導致內(nèi)部齒輪卡死，無法扳回自動。解決辦法：在扳動離合器的時候，手輪要配合著來回轉動使內(nèi)部渦輪脫開，從而輕松達到手自動切換（在手自動切換的時候一定要拉起旁邊黃顏色的卡套）。上海船用閥門氣動制造</p><p
