阿姆斯壯SH-900過熱蒸汽疏水閥
一、阿姆斯壯SH-900過熱蒸汽疏水閥安裝須知
1、疏水閥安裝是否合適，對(duì)疏水閥的正常工作和設(shè)備的生產(chǎn)效率都有直接有影響。安裝疏水閥必須按正規(guī)安裝要求、才能使疏水閥和設(shè)備達(dá)到工作效率。
2、在安裝疏水閥之前一定要用帶壓蒸汽吹掃管道，清除管道中的雜物。
3、疏水閥前應(yīng)安裝過濾器，確保疏水閥不受管道雜物的堵塞，定期清理過濾器。

三、阿姆斯壯SH-900過熱蒸汽疏水閥作業(yè)原理
SH-900過熱蒸汽疏水閥 該閥保持關(guān)閉直到雙金屬元件冷卻，從而使閥門打開，排出冷凝水和不凝性氣體，然后再次關(guān)閉時(shí)，蒸汽溫度達(dá)到。
SH系列過熱蒸汽疏水閥自動(dòng)變化的情況調(diào)整。閥門中的熱元件產(chǎn)生力來抵消壓力的上升。容量為11000磅/小時(shí)（4990公斤/小時(shí)，過熱蒸汽疏水閥sh-900系列操作的影響，溫度升高對(duì)恒溫雙金屬元件。
在啟動(dòng)時(shí)，閥門打開，使大量的不凝性氣體和冷的冷凝水被從系統(tǒng)中刪除。當(dāng)系統(tǒng)達(dá)到蒸汽溫度時(shí)，元件變得足夠熱，以拉上疏水閥的閥桿，關(guān)閉閥門。

For pressures to 900 psig (62 bar) . . .
Capacities to 11,000 lb/hr (4990 kg/hr)
SH-900 Series Superheat Steam Traps operate by the effect that rising temperature has on the thermostatic bimetallic elements.
At start-up, the valve is wide open, which allows a large volume of non-condensables and cold condensate to be removed from the system. When the system reaches steam temperature, the elements become sufficiently hot to pull on the trap’s valve stem, closing the valve.
The valve remains closed until the bimetallic elements cool, thus allowing the valve to crack open, vent the condensate and non-condensables, and then close again when steam temperature is reached.
The SH Series Superheat Steam Traps adjust automatically to changing conditions. Hot elements in the valve generate forces to offset rises in pressure.[本信息來自于今日推薦網(wǎng)]
