according to different working principle of the steam trap, the trap can be turned into the following several types:

a, mechanical type: rely on steam trap with the changing of water level in the action, including: the ball float, float for a closed hollow sphere exposure upward float type: float for opening up the bucket exposure down float type: float down with the bucket

2, hot static type: depend on the liquid temperature change and action, including: the bimetallic strip: original sensitive for bimetallic strip steam pressure type: original sensitive for corrugated tube or cartridge, internal filling the volatile liquid

three, thermodynamic model: depend on the change of the thermal dynamic properties of the liquid and action. Disc type: because be in the same pressure, liquid and gas flow velocity is different, the different dynamic, static pressure and driving disc Industrial Valves action pulse type: due to the different temperature of the condensate by polar string orifice plate, sitting between the throttling orifice plate between the different pressure of form, the driven disc movement.
