進(jìn)口蒸汽疏水閥（Steam Trap），也稱蒸汽疏水器，是用于蒸汽管網(wǎng)及設(shè)備中，能“識(shí)別”蒸汽和凝結(jié)水，能起到阻汽排水作用，根據(jù)蒸汽和凝結(jié)水的密度差、溫度差和相變能自動(dòng)排出凝結(jié)水、空氣及其它不凝結(jié)氣體，并zui大限度阻止蒸汽泄漏的閥門。Steam traps for steam pipe network and equipment, be "identified" steam and condensate, steam trap can play a role, according to the steam and condensate density, temperature, and phase transitions can automatically discharge condensate, air and other non-condensable gases and maximizing preventing steam leakage valve

能有效節(jié)能，并有效保護(hù)蒸汽管道中的其他裝置，比如減壓閥及安全閥。蒸汽疏水閥分為：機(jī)械型，浮球式，熱靜力型，雙金屬片，熱動(dòng)力型，圓盤式，脈沖式。
