工作原理
疏水閥在蒸汽加熱系統(tǒng)中起到阻汽排水作用,選擇合適的疏水閥,可使蒸汽加熱設(shè)備達(dá)到zui高工作效率。要想達(dá)到的效果,就要對各種類型疏水閥的工作性能、特點進(jìn)行全面的了解。 疏水閥的品種很多,各有不同的性能。選用疏水閥時,首先應(yīng)選其特性能滿足蒸汽加熱設(shè)備的*運行,然后才考慮其他客觀條件,這樣選擇你所需要的疏水閥才是正確和有效的。 疏水閥要能“識別”蒸汽和凝結(jié)水,才能起到阻汽排水作用。“識別” 蒸汽和凝結(jié)水基于三個原理:密度差、溫度差和相變。于是就根據(jù)三個原理制造出三種類型的疏水閥:分類為機(jī)械型、熱靜力型、熱動力型。
