style="text-indent:25px">電站止回閥按結(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。升降式止回閥可分為立式和臥式兩種。旋啟式止回閥分為單瓣式、雙瓣式和多瓣式三種。蝶式止回閥為直通式、以上幾種止回閥在連接形式上可分為螺紋連接、法蘭連接和焊接三種。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，可以防止介質(zhì)倒流的閥門叫止回閥。止回閥屬于自動(dòng)閥類，鄭州對(duì)焊連接電站止回閥，鄭州對(duì)焊連接電站止回閥，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)，鄭州對(duì)焊連接電站止回閥，以防止發(fā)生事故。安裝時(shí)注意介質(zhì)流動(dòng)的方向應(yīng)與電站止回閥閥體所票箭頭方向一致。鄭州對(duì)焊連接電站止回閥</p><div

style="text-indent:25px">電站高溫鉻鉬鋼止回閥設(shè)計(jì)特點(diǎn)：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。單瓣旋啟式止回閥一般適用于中等口徑的場(chǎng)合。大口徑管路選用單瓣旋啟式止回閥時(shí)，為減少水錘壓力，比較好的是采用能減小水錘壓力的緩閉止回閥。雙瓣旋啟式止回閥適用于大中口徑管路。對(duì)夾雙瓣旋啟式止回閥結(jié)構(gòu)小、重量輕，是一種發(fā)展較快的止回閥；多瓣旋啟式止回閥適用于大口徑管道路。立式止回閥正常處于關(guān)閉狀態(tài)，由于管線中進(jìn)口端介質(zhì)的壓力作用，而克服彈簧阻力使閥門開啟。當(dāng)進(jìn)口端介質(zhì)壓力低于出口端時(shí)，彈簧將閥芯推向閥座而使閥門關(guān)閉，阻止介質(zhì)逆流，故起止回作用。</p><p style="text-indent:25px">止回閥還可用于給其中的壓力可能升至超過系統(tǒng)壓的輔助系統(tǒng)提供補(bǔ)給的管路上。止回閥主要可分為旋啟式止回閥(依重心旋轉(zhuǎn))與升降式止回閥(沿軸線移動(dòng))。止回閥這種類型的閥門的作用是只允許介質(zhì)向一個(gè)方向流動(dòng)，而且阻止反方向流動(dòng)。通常這種閥門是自動(dòng)工作的，在一個(gè)方向流動(dòng)的流體壓力作用下，閥瓣打開;流體反方向流動(dòng)時(shí)，由流體壓力和閥瓣的自重合閥瓣作用于閥座，從而切斷流動(dòng)。其中止回閥就屬于這種類型的閥門，它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。電站止回閥應(yīng)安裝在水平管道上介質(zhì)流向從下往上流(正流)。</p><div

style="text-indent:25px">焊接式電站止回閥用途：焊接連接的止回閥適用于公稱壓力PN20.0～32.0Mpa，工作溫度≤540℃(其中P(57)170V工作溫度為570℃)的石油、化工、水力、火力電站等各種工況的管路上，切斷或接通介質(zhì)。適用介質(zhì)為：水、油品、蒸汽等。焊接式電站止回閥結(jié)構(gòu)特點(diǎn)： 1.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2.閥門中腔采用壓力自緊式密封結(jié)構(gòu)，介質(zhì)壓力越高,密封性能越好。 3.支管兩端為對(duì)焊連接，適應(yīng)不同的接管要求。 4.閥瓣、閥座的密封面采用司太立（stellite）鈷基硬質(zhì)合金堆焊而成，耐磨、耐高溫，抗擦傷性能好、使用壽命長(zhǎng)。 5.高溫耐壓部件采用質(zhì)量耐熱合金鋼制造,安全可靠,性能穩(wěn)定,使用壽命長(zhǎng)。鄭州對(duì)焊連接電站止回閥</p><p
