style="text-indent:25px">按材質(zhì)分類:(止回閥主體材質(zhì)) 鑄鐵止回閥. 不銹鋼止回閥. 電站止回閥是能自動阻止流體倒流的閥門。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，閥瓣在流體壓差、本身重力等因素作用下自動關(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，動作可靠，但流體阻力較大，適用于輕小口徑的場合。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。</p><p style="text-indent:25px">高溫高壓電站止回閥有兩種標(biāo)準(zhǔn)形式，其遵循的溫度-壓力等級是一致的，在一些管道中存在著某種互換關(guān)系。中部采用無閥蓋壓力自緊式，在高溫高壓工況下具有良好的密封性能。自密封圈有兩種材料，一種是低碳鋼，另一種是柔性石墨316絲(網(wǎng))。密封面上層焊鈷基硬質(zhì)合金，其加工后的純金屬層≥3mm，具有耐磨、耐高溫、抗腐蝕、抗擦傷、使用壽命長。支管兩端為焊接結(jié)構(gòu)，焊接坡口可按標(biāo)準(zhǔn)或用戶要求制作。適用于火電廠、石油化工、冶金等高溫高壓的水、蒸汽、油品、過熱蒸汽的管道上作防止介質(zhì)回流的裝置。旋啟式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。</p><div

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。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。電站止回閥安裝時注意介質(zhì)流動的方向應(yīng)與閥體所票箭頭方向一致。山東高溫高壓旋啟止回閥廠家</p><p
