火力發(fā)電廠(chǎng)閥門(mén)帶壓堵漏技術(shù)應(yīng)注意什么發(fā)電廠(chǎng)閥門(mén)主要用于控制各種設(shè)備及其管路上流體介質(zhì)的運(yùn)行，閥門(mén)的泄漏常發(fā)生在填料、法蘭密封及閥體上，閥門(mén)長(zhǎng)時(shí)間泄漏可造成閥桿和法蘭密封面的沖蝕，**終可使閥門(mén)報(bào)廢，加上介質(zhì)流體的損失，使電廠(chǎng)的消耗增加，成本上升，經(jīng)濟(jì)效益下降。如果介質(zhì)流體0、易燃、易爆、腐蝕性等發(fā)生外泄漏，則容易發(fā)生中毒、火災(zāi)、等傷亡***和加快廠(chǎng)房設(shè)備的腐蝕速度，縮短其使用壽命，嚴(yán)重時(shí)污染周邊環(huán)境，破壞電力生產(chǎn)，損害人們的身體健康。泄漏的存在嚴(yán)重威脅著安全生產(chǎn)，使電廠(chǎng)的非計(jì)劃停機(jī)***增多。以下介紹一些閥門(mén)泄漏原因及堵漏方法以及對(duì)閥門(mén)的維修和維護(hù)方法，供參考。2閥門(mén)外漏的形式及因素閥門(mén)填料的泄漏及原因閥門(mén)在操作使用過(guò)程中，閥桿同填料之間存在著相對(duì)運(yùn)動(dòng)，它包括轉(zhuǎn)動(dòng)和軸向移動(dòng)。隨著開(kāi)關(guān)次數(shù)的增加，相對(duì)運(yùn)動(dòng)的次數(shù)也隨之增多，還有溫度，壓力和流體介質(zhì)的特性等影響，閥門(mén)填料是**容易發(fā)生泄漏的部位。它是由于填料接觸壓力的逐漸減弱，填料自身的老化，失去了彈性等原因引起的。這時(shí)壓力介質(zhì)就會(huì)沿著填料與閥桿的接觸間隙向外泄漏，長(zhǎng)時(shí)間會(huì)把部分填料吹走和將閥桿沖刷出溝槽，從而使泄漏擴(kuò)大化。龍子湖區(qū)手柄溝槽蝶閥門(mén)廠(chǎng)家耐腐蝕：內(nèi)腔采用***環(huán)氧樹(shù)脂涂裝，防止腐蝕和生銹，不但可供生飲，而且可用污水系統(tǒng)。</p><div
