諸如大型火力發(fā)電站上的安全閥、石油化工裝置上用的安全閥、核電站壓水堆一回路裝置上的安全閥等。這些裝置上的安全閥，保證了系統(tǒng)的正常運(yùn)行和安全。有關(guān)詳細(xì)情況，請參閱這方面的專著。4.疏水閥的選用疏水閥是從貯有蒸汽的密閉容器內(nèi)自動排出凝結(jié)水，同時(shí)保持不泄漏新鮮蒸汽的一種自動控制裝置，在必要時(shí)也允許蒸汽按預(yù)定的流量通過。在現(xiàn)代社會中，蒸汽***地應(yīng)用于工農(nóng)業(yè)生產(chǎn)和生活設(shè)施中，無論在蒸汽的輸送管道系統(tǒng)，還是利用蒸汽來進(jìn)行加熱、干燥、保溫、消毒、蒸煮、濃縮、換熱、采暖、空調(diào)等工藝過程中所產(chǎn)生的凝結(jié)水，都需要通過蒸汽疏水閥排除干凈，而不允許蒸汽泄漏掉。按啟閉件的驅(qū)動方式，蒸汽疏水閥可分為三類：由凝結(jié)水液位變化驅(qū)動的機(jī)械型蒸汽疏水閥；由凝結(jié)水溫度變化驅(qū)動的熱靜力型蒸汽疏水閥；由凝結(jié)水動態(tài)特性驅(qū)動的熱動力型蒸汽疏水閥。疏水閥結(jié)構(gòu)型式見表1-25。蒸汽疏水閥是蒸汽使用系統(tǒng)的重要附件，其性能的優(yōu)劣，對于系統(tǒng)的正常運(yùn)行。設(shè)備熱效率的提高及能源的合理利用等方面具有重要作用。⑴機(jī)械型蒸汽疏水閥這類疏水閥主要有密閉浮子式、敞口向上浮子式、敞口向下浮子式等。這類型式的蒸汽疏水閥的工作原理運(yùn)用了古老的阿基米德原理，性能可靠。阿克蘇暗桿軟密封閘閥的價(jià)格。烏魯木齊黃銅絲扣平衡閥</p><p

脈沖式蒸汽疏水閥也具有體積小、重量輕的特點(diǎn)，但結(jié)構(gòu)復(fù)雜，制造精度要求高、價(jià)格貴。⑷疏水閥的選用由于各種型式的蒸汽疏水閥各有不同的優(yōu)缺點(diǎn)和不同的適用條件，因此多年以來各種型式的蒸汽疏水閥長期并存，應(yīng)用于各種工業(yè)管道中。在諸多型式的疏水閥中，必須正確地選擇適合某一系統(tǒng)中的疏水閥，因?yàn)檫@對系統(tǒng)的正常運(yùn)行影響很大，選擇恰當(dāng)可提高熱效率和節(jié)省燃料。正確的選型應(yīng)按下列標(biāo)準(zhǔn)：①蒸汽疏水閥的公稱壓力及工作溫度應(yīng)大于或等于蒸汽管道及用汽設(shè)備的**高工作壓力及**高工作溫度。②蒸汽疏水閥必須區(qū)別類型，按其工作性能、條件和凝結(jié)水排放量進(jìn)行選擇，不得只以蒸汽疏水閥的公稱通徑作為選擇依據(jù)。③在凝結(jié)水回收系統(tǒng)中，若利用工作背壓回收凝結(jié)水時(shí)，應(yīng)選用背壓率較高的蒸汽疏水閥（如機(jī)械型蒸汽疏水閥）。④當(dāng)用汽設(shè)備內(nèi)用汽不得積存凝結(jié)水時(shí)，應(yīng)選用能連續(xù)排出飽和凝結(jié)水的蒸汽疏水閥（如浮球式蒸汽疏水閥）。⑤在凝結(jié)水回收系統(tǒng)中，用汽設(shè)備用汽排出飽和凝結(jié)水，又用汽及時(shí)排除不凝結(jié)性氣體時(shí)，應(yīng)采用能飽和水的蒸汽疏水閥與排氣裝置并聯(lián)的疏水裝置或采用同時(shí)具有排水、排氣兩種功能的蒸汽疏水閥（如特經(jīng)理型蒸汽疏水閥）。⑥當(dāng)用汽設(shè)備工作壓力經(jīng)常波動時(shí)。伊寧黃銅絲扣閘閥批發(fā)</p><p
