style="text-indent:25px">電站截止閥維護(hù)保養(yǎng)截止閥來說，注脂是其使用中一個(gè)較為常見的操作，而注脂操作進(jìn)行的好與壞，將會(huì)直接影響到閥門的穩(wěn)定運(yùn)行，那我們在此過程中需要注意哪些問題呢。截止閥是一種常用的截?cái)嚅y，主要用來接通或截?cái)喙苈分械慕橘|(zhì)，一般不用于調(diào)節(jié)流量。截止閥適用的壓力、溫度范圍很大，但一般用于中、小口徑的管道。截止閥的主要優(yōu)點(diǎn)：1）與閘閥相比，截止閥的結(jié)構(gòu)較簡單，制造與維修都較方便。2）密封面不易磨損、擦傷，密封性較好，壽命較長。3）啟閉時(shí)閥瓣行程較小，啟閉時(shí)間較短，閥門高度較小。</p><p style="text-indent:25px">電站截止閥具有反向關(guān)閉功能：現(xiàn)在電站截止閥若是在全開或是全閉的狀況下，閥座密封面同球體會(huì)與介質(zhì)相隔離，這時(shí)，介質(zhì)通過時(shí)就不會(huì)引起閥門密封面的侵蝕。適用范圍廣，通徑從小到幾毫米，大到幾米，從高真空至高壓力都可應(yīng)用。電站截止閥能承受系統(tǒng)的極限壓力，閥門的閥芯和閥座所選用的材料具有耐高溫高壓抗流體沖刷的**度性能，密封面及閥芯選用堆焊鈷基合金，密封填料材料具有耐高溫高壓且密封性能好的特點(diǎn)，可以確保閥門密封完好無泄漏。高溫高壓情況填料采用柔性石墨，密封填料位于閥桿螺紋之下以隔絕螺紋與介質(zhì)直接接觸，密封時(shí)閥芯不旋轉(zhuǎn)，以確保密封嚴(yán)密性，該電站閥具有反向關(guān)閉功能。電站截止閥保養(yǎng)的過程中，注脂是非常重要的一步。</p><div

1.采用壓力自緊式密封，閥體支管兩端為焊接連接。 2.閥坐、閥瓣密封面采用鈷基硬質(zhì)合金等離子噴焊而成，耐磨、抗擦傷性能好。 3.閥桿經(jīng)抗腐蝕性氮化處理，有良好的抗腐蝕性和抗擦傷性。電站閥門與其他閥門產(chǎn)品相比的特點(diǎn)是高溫高壓，如果單純從壓力方面比通用閥門低，單純從溫度方面比也比通用閥門低。由于性能技術(shù)特性、工況的特殊使產(chǎn)品也形成了其他產(chǎn)品所替代不了的特點(diǎn)。電站閥門與其他閥門產(chǎn)品相比的特點(diǎn)是高溫高壓，獨(dú)特的自密封設(shè)計(jì)，壓力越高，密封越可靠。山東300lb美標(biāo)截止閥費(fèi)用</p><p
