style="text-indent:25px">蝶閥處于徹底開啟方位時(shí)，蝶板厚度是介質(zhì)流經(jīng)閥體時(shí)的阻力，因而通過該閥門所產(chǎn)生的壓力降很小，故具有較好的流量控制特性。蝶閥有彈密封和金屬的密封兩種密封型式。彈性密封閥門，密封圈可以鑲嵌在閥體上或附在蝶板周邊。采用金屬密封的閥門一般比彈性密封的閥門壽命長，但很難做到徹底密封。金屬密封能習(xí)慣較高的工作溫度，彈性密封則具有受溫度限制的缺點(diǎn)。如果要求蝶閥作為流量控制運(yùn)用，主要的是正確選擇閥門的尺度和類型，鋁合金空氣自動(dòng)蝶閥生產(chǎn)廠家哪家好。蝶閥的結(jié)構(gòu)原理特別適合制作大口徑閥門，鋁合金空氣自動(dòng)蝶閥生產(chǎn)廠家哪家好。蝶閥不僅在石油、煤氣，鋁合金空氣自動(dòng)蝶閥生產(chǎn)廠家哪家好、化工、水處理等一般工業(yè)上得到普遍應(yīng)用，并且還應(yīng)用于熱電站的冷卻水系統(tǒng)。減壓閥是一個(gè)局部阻力可以變化的節(jié)流元件。鋁合金空氣自動(dòng)蝶閥生產(chǎn)廠家哪家好</p><div

style="text-indent:25px">水流量通過減壓閥雖有很大的水頭損失，但由于減少了水的浪費(fèi)并使系統(tǒng)流量分布合理、改善了系統(tǒng)布局與工況，因此總體上仍是節(jié)能的。介質(zhì)為蒸汽的場合，宜選用先導(dǎo)活塞式減壓閥或先導(dǎo)閥波紋管式減壓閥。為了操作、調(diào)整和維修的方便，減壓閥一般應(yīng)安裝在水平管道上。減壓閥工作原理：減壓閥是采用控制閥體內(nèi)的啟閉件的開度來調(diào)節(jié)介質(zhì)的流量，將介質(zhì)的壓力降低，同時(shí)借助閥后壓力的作用調(diào)節(jié)啟閉件的開度，使閥后壓力保持在一定范圍內(nèi)，并在閥體內(nèi)或閥后噴入冷卻水，將介質(zhì)的溫度降低，這種閥門稱為減壓減溫閥。鋁合金空氣自動(dòng)蝶閥生產(chǎn)廠家哪家好</p><p
