style="text-indent:25px">減壓閥可將閥前管路較高的水壓減少至閥后管路所需的水平。減壓閥普遍用于高層建筑、城市給水管網(wǎng)水壓過高的區(qū)域、礦井及其他場合，以保證給水系統(tǒng)中各用水點(diǎn)獲得適當(dāng)?shù)姆?wù)水壓和流量。鑒于水的漏失率和浪費(fèi)程度幾乎同給水系統(tǒng)的水壓大小成正比，因此減壓閥具有改善系統(tǒng)運(yùn)行工況和潛在節(jié)水作用，據(jù)統(tǒng)計(jì)其節(jié)水效果約為30％。減壓閥是氣動調(diào)節(jié)的一個必備配件，主要作用是將氣源的壓力減壓并穩(wěn)定到一個定值，以便于調(diào)節(jié)閥能夠獲得穩(wěn)定的氣源動力用于調(diào)節(jié)控制。</p><p style="text-indent:25px">蝶閥處于徹底開啟方位時，蝶板厚度是介質(zhì)流經(jīng)閥體時的阻力，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。蝶閥的結(jié)構(gòu)原理特別適合制作大口徑閥門。蝶閥不僅在石油、煤氣、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)。蝶閥啟閉件是一個圓盤形的蝶板，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。</p><div
