1.上密封座設(shè)計：我公司提供的所有截止閥都有倒密封設(shè)計，通常情況下，碳鋼截止閥的閥座設(shè)計采用分離式倒密封結(jié)構(gòu)，不銹鋼截止閥的倒密封面非?？煽?。雖然按照標準API600中有倒密封，但這不作為在帶壓情況下更換填料的依據(jù)。 </p> <p> 2.填料密封：通常采用成型柔性石墨作為填料材料，可根據(jù)用戶需求提供PTFE或者復合填料材料。填料與填料函接觸的表面粗糙度為3.2um，可以保證3.閥桿與填料接觸面接合緊密但是旋轉(zhuǎn)自如，經(jīng)過精密的機械加工的閥桿密封面粗糙度0.8um可以保證閥桿可靠的密封。 </p> <p> 4.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zui常見的結(jié)構(gòu)，但其流體的阻力zui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。 </p> <p> <br /> </p> <p> <br />

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，閥體受閥桿的機械施壓作用，緊壓在閥座上。2當逆時針轉(zhuǎn)動手輪時，閥桿則反向運動，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，順時針旋轉(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)的導銷的作用，使閥桿和閘板同時旋轉(zhuǎn)90度。3 快要關(guān)閉時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)動的之后幾圈，閥桿底部的角形平面機械地楔向壓迫球體，使其緊密地壓在閥座上，達到完全密封。電站焊接截止閥按密封形式區(qū)分，有填料密封截止閥和波紋管密封截止閥。</p><div style="width:100%;text-align: center;"><img

鑄鋼電動法蘭截止閥由于開閉過程中密封面之間摩擦力小，比較耐用，開啟高度不大，制造容易，維修方便，不僅適用于中低壓，而且適用于高壓。鑄鋼法蘭截止閥可以適用425°C以下石油、化工、制藥、化肥、電力行業(yè)等各種的工況上，截斷或接通調(diào)節(jié)管路介質(zhì)，還可以改變閥瓣的設(shè)計，做節(jié)流閥或者調(diào)節(jié)閥使用。 </p> <p> 二、電動鑄鋼高溫截止閥產(chǎn)品特點： </p> <p> ①閥瓣,閥座密封面用硬質(zhì)合堆焊而成,耐磨,耐高溫,耐腐蝕,抗擦傷性好,使用壽命長。 </p> <p> ②閥桿材料為滲氮鋼,滲氮后的閥桿表面硬度高,耐磨,抗擦傷,抗腐蝕。 </p> <p> ③由于溫度,壓力等原因,閥門口徑DN50以下的閥體,閥蓋為模鍛件,DN65以上的閥體,閥蓋為鑄鋼件。 </p> <p> ④閥體材料品種齊全,填料,墊片可根據(jù)實際工況或用戶要求合理選配,能適用與各種壓力,溫度及介質(zhì)工況。 </p> <p> ⑤安裝閥門時注意介質(zhì)的流向,嚴格按閥門流向箭頭指示的方向安裝。 </p> <p> ⑥電動截止閥盡量垂直安裝,閥桿向上。 </p> <p> <br /> 電站閥門與其他閥門產(chǎn)品相比的特點是高溫高壓，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。安徽高溫高壓電站截止閥廠家</p><p style="text-indent:25px">電站焊接截止閥按介質(zhì)的流向分有直通式截止閥、直流式截止閥和角式截止閥。北京自密封截止閥價格</p><p style="text-indent:25px">電站截止閥優(yōu)點有：結(jié)構(gòu)簡單、體積小、重量輕。緊密可靠，目前閘閥的密封面材料普遍使用塑料、密封性好，在真空系統(tǒng)中也已普遍使用。操作方便，開閉迅速，從全開到全關(guān)只要旋轉(zhuǎn)90度，便于遠距離的控制。維修方便，閘閥結(jié)構(gòu)簡單，密封圈一般都是活動的，拆卸更換都比較方便。在全開或全閉時，球體和閥座的密封面與介質(zhì)隔離，介質(zhì)通過時，不會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用。北京自密封截止閥價格</p><p
