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(zhǎng)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(duì)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(dòng)時(shí)?？死斠离妱?dòng)球閥閥門生產(chǎn)商。</p><div
