style="text-indent:25px">蝶閥又叫翻板閥，是一種結(jié)構(gòu)簡(jiǎn)單的調(diào)節(jié)閥，可用于低壓管道介質(zhì)的開關(guān)控制的蝶閥是指關(guān)閉件（閥瓣或蝶板）為圓盤，圍繞閥軸旋轉(zhuǎn)來(lái)達(dá)到開啟與關(guān)閉的一種閥。閥門可用于控制空氣、水、蒸汽、各種腐蝕性介質(zhì)、泥漿、油品、液態(tài)金屬和放射性介質(zhì)等各種類型流體的流動(dòng)。在管道上主要起切斷和節(jié)流作用。蝶閥啟閉件是一個(gè)圓盤形的蝶板，在閥體內(nèi)繞其自身的軸線旋轉(zhuǎn)，從而達(dá)到啟閉或調(diào)節(jié)的目的。在工業(yè)生產(chǎn)中，蝶閥是一個(gè)很關(guān)鍵的機(jī)械裝置，是很常見的。</p><p style="text-indent:25px">水流量通過(guò)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(chǎng)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(lái)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。調(diào)壓閥的原理是利用了彈簧力與壓力相平衡的原理。</p><div
