class="title">詳細(xì)說明</p><div id="wli23mt" class="box"><p><p style="text-indent:25px">電站焊接截止閥較明顯的優(yōu)點(diǎn)是：在開啟和關(guān)閉過程中，由于閥瓣于閥體密封面間的摩擦力比閘閥小，因而耐磨。焊接截止閥開啟高度一般*為閥座通道直徑的1/4，因此比閘閥小的多。通常在閥體和閥瓣上只有一個(gè)密封面，因而制造工藝性比較好，便于維修。焊接截止閥的選用原則是： 1、高溫、高壓介質(zhì)的管路或裝置上宜選用焊接截止閥。如火電廠、核電站，石油化工系統(tǒng)的高溫、高壓管路上。 2、焊接截止閥用在管路上對(duì)流阻要求不嚴(yán)的管路上。即對(duì)壓力損失考慮不大的地方。 3、小型閥門可選用針閥、儀表閥、取樣閥、壓力針閥等。 4、有流量調(diào)節(jié)或壓力調(diào)節(jié)，但對(duì)調(diào)節(jié)精度要求不高，而且管路直徑又比較小，山東自密封電站截止閥廠家，如公稱通經(jīng)≤50mm 的管路上，山東自密封電站截止閥廠家，宜選用焊接截止閥，山東自密封電站截止閥廠家。 5、合成工業(yè)生產(chǎn)中的小化肥和大化肥宜選用公稱壓力PN160 公稱壓力16MPa 或PN320 公稱壓力32MPa 的高壓角式焊接截止閥或高壓角式節(jié)流閥。電站截止閥介質(zhì)通不會(huì)引起閥門密封面的侵蝕。山東自密封電站截止閥廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="山東自密封電站截止閥廠家,截止閥"

style="text-indent:25px">電站截止閥和法蘭閘閥是同屬一個(gè)類型的閥門，由電動(dòng)執(zhí)行機(jī)構(gòu)或氣動(dòng)執(zhí)行機(jī)構(gòu)和截止閥兩部分組成，區(qū)別在它的關(guān)閉件是個(gè)閥體，閥體繞閥體中心線作旋轉(zhuǎn)來達(dá)到開啟、關(guān)閉的一種閥門。閘閥在管路中主要用來做切斷、分配和改變介質(zhì)的流動(dòng)方向。二片式球閥，三片式球閥，是近年來被大范圍采用的一種新型閥門。4.低扭矩設(shè)計(jì)。特殊結(jié)構(gòu)設(shè)計(jì)的閥桿，只需配一個(gè)小手把閥門就能輕松啟閉。某些沖擊啟閉的高壓截止閥各部件已經(jīng)考慮了這種沖擊力與一般截止閥不能等同。管路初用時(shí)，內(nèi)部臟物較多，可將截止閥微啟，利用介質(zhì)的高速流動(dòng)，將其沖走，然后輕輕關(guān)閉（不能快閉、猛閉，以防殘留雜質(zhì)夾傷密封面），再次開啟，如此重復(fù)多次，沖凈臟物，再投入正常工作。山東自密封電站截止閥廠家鍛鋼電站截止閥與管路連接采用焊接式結(jié)構(gòu)，安裝方便，無泄漏。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="山東自密封電站截止閥廠家,截止閥" src="https://tyunfile.71360.com/UploadFile/jingzhou/637279443826718750/9736086.png"></div><p 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)的之后幾圈，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。</p><p style="text-indent:25px">截止閥的安裝與維護(hù)應(yīng)注意以下事項(xiàng)：1、手輪、手柄操作的截止閥可安裝在管道的任何位置上。2、手輪、手柄及偉動(dòng)機(jī)構(gòu)，不允許作起吊用。3、介質(zhì)的流向應(yīng)與閥體所示箭頭方向一致。截止閥的種類按閥桿螺紋的位置分有外螺紋式、內(nèi)螺紋式。按介質(zhì)的流向分，有直通式、直流式和角式。截止閥按密封形式分，有填料密封截止閥和波紋管密封截止閥。2. 截止閥閥體的結(jié)構(gòu)形式有直通式、直流式和直角式。直通式是常見的結(jié)構(gòu)，但其流體的阻力較大。直流式流體阻力較小，多用于含固體顆?；蛘扯却蟮牧黧w。直角式閥體多采用鍛造，適用于較小通經(jīng)、較高壓力的的截止閥。電站不銹鋼焊接截止閥制造與維修都較方便。</p><div style="width:100%;text-align: center;"><img
