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.
雙金屬型過熱蒸汽疏水閥
雙金屬型蒸汽疏水閥能夠處理大的啟動負荷。當系統溫度和壓力增大時,疏水閥的疊層式鎳-鉻雙金屬元件開始延展,當蒸汽到達疏水閥時緊閉閥門從而防止了蒸汽損失。
雙金屬型疏水閥能抵抗水擊作用。依靠鈦質閥瓣和閥座,雙金屬型疏水閥確保在過熱蒸汽系統惡劣環境仍保持超長使用壽命。
