The classified method of drain valve

Depending on the working principle of the drain valve, drain valve can be turned into the following several types: a, mechanical type: rely on steam drain valve 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 of two, 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 valve 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, drives the valve disc movement.
