style="text-indent:25px">在電站截止閥保養(yǎng)的過程中，注脂是非常重要的一步，能有效的減少摩擦帶來的損壞，那么在電站截止閥注脂過程中，常見的問題都有哪些呢?1.電站截止閥注脂時(shí)，常忽略壓力問題。在注脂操作時(shí)，注脂壓力有規(guī)律地呈峰谷變化。壓力過低，密封漏或失效，壓力過高，注脂口堵塞、密封內(nèi)脂類硬化或密封圈與閥球、閥板抱死。通常注脂壓力過低時(shí)，注入的潤(rùn)滑脂多流入閥腔底部，一般發(fā)生在小型閘閥。而注脂壓力過高，一方面檢查注脂嘴，南京ＷＣ９電站截止閥生產(chǎn)廠家，如是脂孔阻塞判明情況進(jìn)行更換；另一方面是脂類硬化，要使用清洗液，反復(fù)軟化失效的密封脂，并注入新的潤(rùn)滑脂置換。此外，密封型號(hào)和密封材質(zhì)，也影響注脂壓力，不同的密封形式有不同的注脂壓力，一般情況硬密封注脂壓力要高于軟密封。球閥維護(hù)保養(yǎng)時(shí)一般都處于開位狀態(tài)，特殊情況下選擇關(guān)閉保養(yǎng)。其他閥門也不能一概以開位論處。閘閥在養(yǎng)護(hù)時(shí)則必須處于關(guān)閉狀態(tài)，確保潤(rùn)滑脂沿密封圈充滿密封槽溝，如果開位，密封脂則直接掉入流道或閥腔，南京ＷＣ９電站截止閥生產(chǎn)廠家，造成浪費(fèi)，南京ＷＣ９電站截止閥生產(chǎn)廠家。電站截止閥在進(jìn)行調(diào)試的時(shí)候，需要做好調(diào)試的細(xì)節(jié)，從而確保其良好的性能。南京ＷＣ９電站截止閥生產(chǎn)廠家</p><div

style="text-indent:25px">電站截止閥的工作原理：開啟過程： 1在關(guān)閉位置，閥體受閥桿的機(jī)械施壓作用，緊壓在閥座上。 2當(dāng)逆時(shí)針轉(zhuǎn)動(dòng)手輪時(shí)，閥桿則反向運(yùn)動(dòng)，其底部角形平面使球體脫開閥座。 3閥桿繼續(xù)提升，并與閥桿螺旋槽內(nèi)的導(dǎo)銷相互作用，使球體開始無摩擦地旋轉(zhuǎn)。 4直至到全開位置，閥桿提升到極限位置，球體旋轉(zhuǎn)到全開位置。關(guān)閉過程： 1關(guān)閉時(shí)，順時(shí)針旋轉(zhuǎn)手輪，閥桿開始下降并使球體離開閥座開始旋轉(zhuǎn)。 2繼續(xù)旋轉(zhuǎn)手輪，閥桿受到嵌于其上螺旋槽內(nèi)的導(dǎo)銷的作用，使閥桿和閘板同時(shí)旋轉(zhuǎn)90度。 3 快要關(guān)閉時(shí)閘體已在與閥座無接觸的情況下旋轉(zhuǎn)了90度。 4手輪轉(zhuǎn)動(dòng)的較后幾圈，閥桿底部的角形平面機(jī)械地楔向壓迫球體，使其緊密地壓在閥座上，達(dá)到完全密封當(dāng)電站截止閥噪音超過買方要求數(shù)值，因采取降低噪音的措施。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
