圓盤式蒸汽疏水閥特點(diǎn)及原理
圓盤式蒸汽疏水閥結(jié)構(gòu)*、價(jià)格低、動(dòng)作可靠。漏氣率<3%,不受壓力波動(dòng)的影響,壓力范圍大。由于密封面不銹鋼,使用壽命高于國內(nèi)同類產(chǎn)品。
熱動(dòng)力式疏水閥是根據(jù)柏努力定律及蒸汽與凝結(jié)水的物理特性,通過排放凝結(jié)水來改變作用在閥片上的動(dòng)、靜壓力而使疏水閥執(zhí)行無件-----閥片開關(guān)閥門.
圓盤式蒸汽疏水閥工作原理:
當(dāng)裝置剛啟動(dòng)時(shí),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(dāng)壓力、溫度上升后,內(nèi)壓上升,推動(dòng)凝結(jié)水很快地通過疏水閥,在進(jìn)出口之間存有很大的壓降,由于蒸汽比同樣重的凝結(jié)水的體積大的多,而增大流速,這時(shí)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(jìn)入壓力室,將閥片壓在密封環(huán)上,關(guān)閉閥門.當(dāng)壓力室的蒸汽溫度降低,開始冷凝,使壓力室內(nèi)的壓力降低,進(jìn)口壓力托起閥片,疏水閥開啟進(jìn)行排水.
