產品詳情
規格參數
膜盒式蒸汽疏水閥(蒸汽壓力平衡式)是目前國際上最常用的先進節能型疏水閥。膜盒式蒸汽疏水閥的反應非常靈敏,工作時閥前存有高溫凝結水,無蒸汽泄漏,節能效果顯著。
膜盒式在現如今蒸汽管線中是代替低壓(壓力在PN25以下)熱動力(圓盤式)疏水閥或(壓力在PN16以下)雙金屬片式疏水閥的理想替代品。
Bellows Trap
The main acting unit of bellows trap is metal bellows, which is filled with a type of liquid with gasification temperature lower than water’s saturation temperature. When the device just starts, there appears condensate with low temperature in conduits and the liquid in the bellows is in the condensed state. The trap is turned on. When the temperature of condensate water gradually goes up, the liquid in the bellows begins to vaporize and the pressure within it increases. Consequently, the film drives the valve core to move towards the closing direction. Before the condensate water reaches its saturation temperature, the trap is completely shut down. The bellows controls the opening and closing of valves in accordance with steam temperature changes so as to resist steam and discharge water. Available are two alternative bellows with opening temperature
Bellows trap (with balanced steam pressure) is presently the most commonly used advanced energy-saving traps all over the world. As they are sensitive with high-temperature condensate deposits in front of valves while operating, they boast of remarkable energy-saving effect with no steam leakage.
Bellows trap, among all existing steam pipes, are presently the ideal substitute of low-pressure (with pressure below PN25) hot motive (disc) traps or bimetallic elements traps (with pressure below PN16).
