The hot-statical membrance-box steam trap (steam pressure balance type) is the most commonly use advanced energy-saving trap. Embrance-box steam trap has smart response. It has the high temperature condensate water before working, without the steam leakage, the energy-saving effect is remarkable.
Its advantage is: The automatic release air, the volume is small, bear frozen, can install at any position. It maintains conveniently for inspecting, repairing and replacing the parts on the pipeline. The maximum rate of back pressure is ≤ 80%. Its membrance-box is firmly and has a long usage circle.
It has a widely usage for steam pipeline, steam heat tracing pipe, gage heat tracing pipe and the anti-small steam displace of heat-up equipment.
Working Principle
The main actuating member of membrance-box steam trap is metal membrance-box which fills with the liquid of gasified temperature lower than the saturation temperature of water. When the device starts, the pipeline appeared the low temperature condensate water, the liquid in the membrance-box is at the condensation condition, the valve is opened. When the temperature of condenste water gradually rises, the sufficient fluid in the membrance-box starts to evaporate. The pressure in membrance-box goes up, the membrance impetus valve core moves to the closure direction. The trap completely closed before the condensate water reach saturation temperature. The membrance control the valve on-off along with the steam temperature changed for anti-steam drain. It supplies two kinds membrance of the valve temperature is lower than saturation temperature 15 and 30 to choose...
