style="text-indent:25px">電站止回閥的閥瓣在流體壓力作用下開啟，流體從進(jìn)口側(cè)流向出口側(cè)。當(dāng)進(jìn)口側(cè)壓力低于出口側(cè)時(shí)，閥瓣在流體壓差、本身重力等因素作用下自動(dòng)關(guān)閉以防止流體倒流。止回閥一般分為升降式、旋啟式、蝶式及隔膜式等幾種類型。升降式止回閥的結(jié)構(gòu)一般與截止閥相似，其閥瓣沿著通道中以線作升降運(yùn)動(dòng)，動(dòng)作可靠，但流體阻力較大，適用于輕小口徑的場(chǎng)合。升降式止回閥可直通式和立式兩種。直通式升降止回閥一般只能安裝在水平管路，而立式升降止回閥一般就安裝在垂直管路。旋啟式止回閥的閥瓣繞轉(zhuǎn)軸作旋轉(zhuǎn)運(yùn)動(dòng)。其流體阻力一般小于升降式止回閥，它適用于較大口徑的場(chǎng)合。旋啟式止回閥根據(jù)閥瓣的數(shù)目可分為單瓣旋啟式、雙瓣旋啟式及多瓣旋啟式三種。止回閥屬自動(dòng)閥類，又稱逆止閥、單向閥、回流閥或隔離閥。</p><div

style="text-indent:25px">止回閥是指啟閉件為圓形閥瓣并靠自身重量及介質(zhì)壓力產(chǎn)生動(dòng)作來阻斷介質(zhì)倒流的一種閥門。屬自動(dòng)閥類，又稱逆止閥、單向閥、回流閥或隔離閥。閥瓣運(yùn)動(dòng)方式分為升降式和旋啟式。升降式止回閥與截止閥結(jié)構(gòu)類似，*缺少帶動(dòng)閥瓣的閥桿。介質(zhì)從進(jìn)口端(下側(cè)）流入，從出口端（上側(cè)）流出。當(dāng)進(jìn)口壓力大于閥瓣重量及其流動(dòng)阻力之和時(shí)，閥門被開啟。反之，介質(zhì)倒流時(shí)閥門則關(guān)閉。旋啟式止回閥有一個(gè)斜置并能繞軸旋轉(zhuǎn)的閥瓣，工作原理與升降式止回閥相似。止回閥常用作抽水裝置的底閥，可以阻止水的回流。止回閥與截止閥組合使用，可以起到安全隔離的作用。缺點(diǎn)是阻力大，關(guān)閉時(shí)密封性差。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。寧波高壓旋啟止回閥多少錢</p><p style="text-indent:25px">鉻鉬鋼高溫高壓止回閥按結(jié)構(gòu)劃分，可分為升降式止回閥、旋啟式止回閥和蝶式止回閥三種。成都自密封高壓止回閥</p><p style="text-indent:25px">蝶式止回閥包括旋啟式止回閥和升降式止回閥。旋啟式止回閥有一介鉸鏈機(jī)構(gòu)，還有一個(gè)像門一樣的閥瓣自由地靠在傾斜的閥座表面上。為了確保閥瓣每次都能到達(dá)閥座面的合適位置，閥瓣設(shè)計(jì)在鉸鏈機(jī)構(gòu)，以便閥瓣具有足夠有旋啟空間，并使閥瓣真正的、全方面的與閥座接觸。閥瓣可以全部用金屬制成，也可以在金屬上鑲嵌皮革、橡膠、或者采用合成覆蓋面，這取決于使用性能的要求。旋啟式止回閥在完全打開的狀況下，其流體壓力幾乎不受阻礙，因此通過閥門的壓力降相對(duì)較小。升降式止回閥的閥瓣座落位于閥體上閥座密封面上。此閥門除了閥瓣可以自由地升降之外，其余部分如同截止閥一樣，流體壓力使閥瓣從閥座密封面上抬起，介質(zhì)回流導(dǎo)致閥瓣回落到閥座上，并切斷流動(dòng)。根據(jù)使用條件，閥瓣可以是全金屬結(jié)構(gòu)，也可以是在閥瓣架上鑲嵌橡膠墊或橡膠環(huán)的形式。像截止閥一樣，流體通過升降式止回閥的通道也是狹窄的，因此通過升降式止回閥的壓力降比旋啟式止回閥大些，而且旋啟式止回閥的流量受到的限制很少。本類閥門在管道中一般應(yīng)當(dāng)水平安裝。成都自密封高壓止回閥</p><p
