The three types of pneumatic valve steam traps

hydrophobic pneumatic valve is used in steam pipe network and devices, can automatically discharge condensate, air and other gases not condensation, and resistance of steam leakage of pneumatic valve.

depending on the working principle of the pneumatic valve steam traps, steam hydrophobic pneumatic valve can be turned into the following three types:

and mechanical type: rely on pneumatic valve steam traps with the changing of water level in the action, including the following three:

ball float, float for a closed hollow sphere; Exposure to float upward: float for opening up the bucket; Exposure to downward float type: float down with the bucket.

and hot static type: depend on the liquid temperature change and action, including:

bimetallic strip: original sensitive for bimetallic strip

steam pressure type: original sensitive for corrugated tube or cartridge, filling the volatile liquid inside the

and thermodynamic model: depend on the change of the thermal dynamic properties of the liquid and actions, including:

disc type: because under the same pressure, liquid and gas flow velocity is different, the different dynamic, static pressure, pneumatic valve plates driven disc movement

impulse 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, driven by pneumatic disc movement
