圓盤式蒸汽疏水閥特點及原理
圓盤式蒸汽疏水閥結構獨特、價格低、動作可靠。漏氣率<3%，不受壓力波動的影響，壓力范圍大。由于密封面不銹鋼，使用壽命高于國內同類產(chǎn)品。
熱動力式疏水閥是根據(jù)柏努力定律及蒸汽與凝結水的物理特性,通過排放凝結水來改變作用在閥片上的動、靜壓力而使疏水閥執(zhí)行無件-----閥片開關閥門.
圓盤式蒸汽疏水閥工作原理:
當裝置剛啟動時,首先在較低的壓力下空氣和冷凝水流過疏水閥,通過入口孔托起閥片,再由出口孔排出,當壓力、溫度上升后,內壓上升,推動凝結水很快地通過疏水閥,在進出口之間存有很大的壓降,由于蒸汽比同樣重的凝結水的體積大的多,而增大流速,這時閥片的靜壓降低,使閥片下落,蒸汽從出口孔中間由四周流向閥片和閥蓋之間的間隙,進入壓力室,將閥片壓在密封環(huán)上,關閉閥門.當壓力室的蒸汽溫度降低,開始冷凝,使壓力室內的壓力降低,進口壓力托起閥片,疏水閥開啟進行排水.
