★鈷、鉻、鎢合金密封面,使用壽命長。閥座和球形閥芯采用優(yōu)質(zhì)合金,耐磨損,耐腐蝕,經(jīng)久耐用。
★球形閥芯密封好。采用磨削加工并在機械裝置上與閥座配研的球形閥芯,密封性能好,在工作時無集中磨損,能延長使用壽命。
★汽水分離可靠。倒置桶向下的開口和閥座孔均處于液封狀態(tài),蒸汽不能到達被水密封的閥孔,能可靠地將水、汽分離。
★排空氣性能好。倒置桶上沒有溢出排氣孔,可有效地阻止蒸汽汽鎖、空氣所堵現(xiàn)象。
★背壓高(85%)有利于在凝結(jié)水回收系統(tǒng)中使用。
★耐水擊。開口桶結(jié)構(gòu)不會由于水擊現(xiàn)象而遭損壞。
★維護簡便。內(nèi)部零件采用不銹鋼制造,均安裝在閥蓋上,并沒有過濾網(wǎng)裝置,是常維護簡便。
★可選擇有內(nèi)裝式止回閥裝置。帶有內(nèi)裝止回閥是一種適用在低過熱汽工況上的理想疏水閥。
●The cover uses cobalt-chromium-tungsten alloy,featuring long durability.Unit base and globe valve spool are made out of quality alloy,which boasts anti-abrasive ability and good corrosion resistance.
●Globe valve featuring good tightness.Globe valve spool,which uses abrasive machining featuring good tightness,non-focus abrasion procedure can extend using durability.
●Reliable seperation ability between air and water.inverted tand and valve base liquid blocded to stop steam from arriving valve ga-te,seperating the steam and water.
●Good air-out ability. Air-out hole on the tank can avoid steam and block.
●High backing pressure.Used in condensation water recycling system.
●Easy maintenance Inner parts are made out of stainless steel,it also has screen for easy maintenance.
●Built-in check valve system.It is ideal valve for steam and over-heating steam.

工作原理:Principle of Work
|
倒置桶疏水閥的開啟和關(guān)閉是根據(jù)凝結(jié)水和蒸汽的密度差來動作的,凝結(jié)水可直接驅(qū)動疏水閥啟閉,其動作準(zhǔn)確,可靠性高。
Open and shut-down is operated by the density variati on bet ween condensation water and steam,Condesation water can drive valve directly,featuring precision and reliability.

工作原理 :
自由浮球式蒸汽疏水閥的結(jié)構(gòu)簡單,內(nèi)部只有一個精細研磨的不銹鋼空心浮球,既是浮子又是啟閉件,無易損零件,使用壽命很長。裝置剛起動時,管道內(nèi)出現(xiàn)空氣和低溫冷凝水,手動排空氣閥能迅速排除不凝結(jié)氣體,疏水閥開始進入工作狀態(tài),低溫冷凝水流進疏水閥,凝結(jié)水的液位上升,浮球上升,開啟閥門。裝置很快提升溫度,管道內(nèi)溫度上升到飽和溫度之前,自動排空氣閥已經(jīng)關(guān)閉;裝置進入正常運行狀況,凝結(jié)水減少,液位下降,浮球隨液位升降調(diào)節(jié)閥孔流量;當(dāng)凝結(jié)水停止進入時,浮球隨介質(zhì)流向逼近閥座,關(guān)閉閥門。自由浮球式蒸汽疏水閥的閥座總處于液位以下,形成水封,無蒸汽泄漏。
