style="text-indent:25px">止回閥主要是用來防止管道中的介質(zhì)倒流使用。底閥及鴨嘴閥也是屬于止回閥系類。止回閥可分為升降式、旋啟式、蝶型三種。升降式又可分為立式和臥式兩種，升降式結(jié)構(gòu)是沿軸線移動(dòng)。旋啟式還可分為單瓣式、雙瓣式和多瓣式三種，旋啟式結(jié)構(gòu)是依重心旋轉(zhuǎn)。蝶型結(jié)構(gòu)為直通流道。止回閥的啟閉是依靠介質(zhì)流動(dòng)力量自行開啟和關(guān)閉。止回閥屬于自動(dòng)閥產(chǎn)品，止回閥只允許介質(zhì)向一個(gè)方向流動(dòng)的管路中使用，防止介質(zhì)回流的現(xiàn)象發(fā)生。其使用范圍很廣，可適用大小口徑、各種介質(zhì)、電站高壓系統(tǒng)中使用。廣州自密封電站止回閥費(fèi)用旋啟式止回閥的閥瓣繞轉(zhuǎn)軸作旋轉(zhuǎn)運(yùn)動(dòng)。</p><div

style="text-indent:25px">電站止回閥：止回閥又稱單向閥或逆止閥，其作用是防止管路中的介質(zhì)倒流。也屬于止回閥類。啟閉件靠介質(zhì)流動(dòng)和力量自行開啟或關(guān)閉，以防止介質(zhì)倒流的閥門叫止回閥。止回閥屬于自動(dòng)閥類，主要用于介質(zhì)單向流動(dòng)的管道上，只允許介質(zhì)向一個(gè)方向流動(dòng)，以防止發(fā)生事故。安裝注意事頂：1、在管線中不要使止回閥承受重量，大型的止回閥應(yīng)**支撐，使之不受管系產(chǎn)生的壓力的影響。2、安裝時(shí)注意介質(zhì)流動(dòng)的方向應(yīng)與閥體所票箭頭方向一致。3、升降式垂直瓣止回閥應(yīng)安裝在垂直管道上。4、升降式水平瓣止回閥應(yīng)安裝在水平管道上。</p><p style="text-indent:25px">電站止回閥的清理檢查：檢查閥芯及閥體上的閥線，閥線上應(yīng)無影響密封性能的凹槽、氣孔及橫貫密封面的痕跡，應(yīng)全周接觸無間斷。若發(fā)現(xiàn)有影響密封性能的缺陷應(yīng)進(jìn)行研磨等處理。檢查閥蝶與搖臂間的連接情況，調(diào)整墊片與搖臂間隙為1～1.2mm之間，不應(yīng)過大也不應(yīng)過小，否則應(yīng)進(jìn)行調(diào)整。閥蝶與搖臂的緊固螺母連接應(yīng)牢固，定位的焊點(diǎn)應(yīng)完整、無裂紋，閥蝶軸與搖臂圈的間隙應(yīng)符合要求。檢查杠桿軸、搖臂軸與大小襯套及播臂的間隙應(yīng)符合要求，各軸表面及襯套內(nèi)壁表面應(yīng)光潔、無凹坑。止回閥前后介質(zhì)壓力處于近到平衡而又互相“拉鋸”，閥瓣經(jīng)常與閥座拍打，某些脆性材料做成的閥瓣就被打碎。</p><div

style="text-indent:25px">一、H41H升降式止回閥概述：升降式止回閥選用于公稱壓力PN1.6～6.4MPa,工作溫度-29～550℃的石油、化工、火力電站等各種工況的管路上。適用介質(zhì)為：水、油品、蒸汽等。二、H41H升降式止回閥結(jié)構(gòu)特點(diǎn)： 1、升降式止回閥具有結(jié)構(gòu)簡單，動(dòng)作可靠，維修方便等優(yōu)點(diǎn)，普遍應(yīng)用于凈化設(shè)備、石油、化工、冶金、電力、輕紡等生產(chǎn)過程中 2、當(dāng)介質(zhì)由閥體箭頭所示流向進(jìn)入閥體，介質(zhì)的壓力作用在閥瓣上產(chǎn)生向上的推力，當(dāng)介質(zhì)推力大于閥瓣重力時(shí)，閥門打開。當(dāng)閥后介質(zhì)壓力作用在閥瓣上的力加上閥瓣自身重力大于閥前壓力作用在閥瓣上的力時(shí)，閥門關(guān)閉，阻止介質(zhì)倒流。可按用戶要求設(shè)計(jì)制造不同結(jié)構(gòu)形式和連接形式的止回閥，為各種設(shè)備配套使用。美標(biāo)電站止回閥產(chǎn)品設(shè)計(jì)制造按E101和JB/T3595-93標(biāo)準(zhǔn)的規(guī)定，結(jié)構(gòu)合理，性能優(yōu)良，造型。浙江ＷＣ９美標(biāo)電站止回閥</p><p style="text-indent:25px">電站止回閥常見故障有：1、閥瓣打碎；2、介質(zhì)倒流。福建日標(biāo)止回閥</p><p style="text-indent:25px">鉻鉬鋼高溫截止閥作用原理：鉻鉬鋼高溫截止閥的閉合原理是依靠閥杠壓力，使閥瓣密封面與閥座密封面緊密貼合，阻止介質(zhì)流通。我國閥門“三化給”曾規(guī)定，截止閥的流向，一律采用自上而下，所以安裝時(shí)有方向性。截止閥的結(jié)構(gòu) 長度大于閘閥，同時(shí)流體阻力大，長期運(yùn)行時(shí)，密封可靠性不強(qiáng)。截止閥，也叫截門，是使用較為普遍的一種閥門之一，它之所以廣受歡迎，是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。福建日標(biāo)止回閥</p><p
