雙金屬型蒸汽疏水閥能夠處理大的啟動(dòng)負(fù)荷。當(dāng)系統(tǒng)溫度和壓力增大時(shí)，疏水閥的疊層式鎳－鉻雙金屬元件開(kāi)始延展，當(dāng)蒸汽到達(dá)疏水閥時(shí)緊閉閥門(mén)從而防止了蒸汽損失。
雙金屬型疏水閥能抵抗水擊作用。依靠鈦質(zhì)閥瓣和閥座，雙金屬型疏水閥確保在過(guò)熱蒸汽系統(tǒng)惡劣環(huán)境仍保持超長(zhǎng)使用壽命。
SH-2000 Series Superheat Traps
Bimetallic steam traps for superheat conditions
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 conditions 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 savings in labor cost and ultimate flexibility—because inverted bucket, thermostatic, thermostatic wafer, disc, and float and thermostatic steam traps can all be installed on the same connector.
