一、进口过热蒸汽疏水阀SH-2000特色
阿姆斯壮SH-2000有密封，不锈钢机身，重量轻，结构紧凑，高度抗腐蚀。它适用于阿姆斯壮360˚万向接头或疏水阀站（电视）。这使得它很容易安装和更换，因为陷阱可以被删除，而连接器仍然在网上。这意味着节省劳动力成本和***终的灵活性，因为倒桶，恒温，恒温晶片，光盘，和浮动和恒温蒸汽疏水阀都可以安装在同一连接器上。
二、进口过热蒸汽疏水阀SH-2000作业原理
在启动时，阀门打开，使大量的不凝性气体和冷的冷凝水被从系统中删除。当系统达到蒸汽温度时，元件变得足够热，以拉上疏水阀的阀杆，关闭阀门。
该阀保持关闭直到双金属元件冷却，从而使阀门打开，排放冷凝水和不凝性气体，然后再次关闭时，蒸汽温度达到。
SH-2000 Series Superheat Traps
Bimetallic steam traps for superheat conditi***
For pressures to 400 psig (28 bar) . . .
Cold water capacities to 4800 lb/hr (2175 kg/hr)
SH Series Superheat Steam Traps operate by the effect that rising temperature has on the thermostatic bimetallic elements.
The effect of rising temperature on bimetallic elements operates the Armstrong SH-2000 bimetallic steam trap. It adjusts to changing conditi*** because the curving of the bimetallic elements, caused by increasing temperature, compensates for increasing pressure.
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, venting the condensate and non-condensables, and then close again when steam temperature is reached.
The Armstrong SH-2000 has a sealed, stainless steel body that is lightweight, compact and highly resistant to corrosion. It is adaptable to an Armstrong 360˚ Universal Connector or a Trap Valve Station (TVS). This makes it easy to install and replace, as the trap can be removed while the connector remains in-line. That means s***ings in labor cost and ultimate flexibility—because inverted ***et, thermostatic, thermostatic wafer, disc, and float and thermostatic steam traps can all be installed on the same connector.
