圓盤式蒸汽疏水閥是根據(jù)熱動(dòng)力學(xué)原理，利用蒸汽和凝結(jié)水的熱動(dòng)力學(xué)不同熱性，引起動(dòng)能和勢能動(dòng)靜壓變化，使動(dòng)作件閥片上下壓差變化，啟動(dòng)閥片開啟和關(guān)閉，從而達(dá)到阻氣排水目的。廣泛用于蒸汽主管道，伴熱管線、夾套鍋及各種小型蒸汽設(shè)備。

結(jié)構(gòu)特點(diǎn)：1、本閥結(jié)構(gòu)結(jié)實(shí)、重量輕、體積小使用壓力范圍大，不需任何調(diào)節(jié)。
2、具有空氣排放裝置，迅速排除初時(shí)空氣、保證快速啟動(dòng)。
3、可承受過熱蒸汽、抗冰凍能力強(qiáng)，安裝位置不受限制，均能正常工作。
Introduction:According to the thermodynatic principle,the disc trap drives the change of the power,causing differences between the upper and lower valve discs.The valve disc will be opened and closed accordingly to resist gas and discharge water.This kind of trap enjoys an extensive application in main pipelines,heat accompanying pipelines and small steam equipments.
Structure:1.This trap is featured with solid structure,light weight,small volume and different pressure without any adjustment.
2.Hving gas discharging equipment for rapidly discharging gas to ensure fast start.
3.Excellent abilities to endure steam and to resist frozen.It can be installed in free way.
