Model of the steam trap on the pipeline
Thread Content
There is a steam trap at the turbine inlet, which ensures that steam can enter the turbine properly while simultaneously removing water from the saturated steam. What is the name of this valve, and what is its model?

Type | Item
---|---
Mechanical | Thermal-static | Thermal-dynamic
1. Working Principle | Utilizes the density difference between steam and condensate water | Utilizes the temperature difference between steam and condensate water | Utilizes the phase change of steam and condensate water
2. Drainage Temperature (Subcooling) | Saturated (~0°C), Subcooled water (10–30°C), Subcooled water (6–8°C)
3. Steam Leakage Rate | 2–3%, 1%, 2–3%
4. Allowable Back Pressure | 0.8P, 10.5P, 10.5P, 1–0.25P1
5. Size of Structure | Large, Small, Minimum
6. Installation Direction | Horizontal, Horizontal/Vertical, Horizontal/Vertical
7. Operating Performance | Reliable with short operation intervals, Relatively reliable but with longer intervals, Relatively reliable yet with even longer intervals
8. Service Life | Long, Short, Shortest
9. Types | Float-type (linkage float type, free float type), Bucket-type (float bucket type, inverted bucket type), Bimetallic type, Diaphragm type, Orifice plate type, Pulse type, Nozzle type

I’m not too sure about this here either; it’s always been called a steam vent valve. The pipeline is quite long, and there’s a silencer installed at the top, along with hydrophobic tubes. I remember once the pipeline vibrated severely, and that was due to too much water in the steam. Once the hydrophobic devices were adjusted, the problem was resolved
