Trap is used in steam pipe network and equipment, can automatically discharge condensate, air and other non-condensable gas, and water vapor leakage valve. According to the different working principle of steam traps, steam traps can be divided into the following three types: Mechanical type: Rely on the changes in the height of the condensate water vapor in the steam traps, including: Float type: Float closed hollow sphere Open up Float type: float up to open the barrel-type Open downward Float: the float is open down barrel type Static type: relying on liquid temperature changes and movements, including: bimetal: sensitive to the original Bimetal vapor pressure type: sensitive original bellows or ink cartridges, filled with volatile liquid inside Thermodynamic: Rely on the thermodynamic properties of the liquid changes. Disc type: Due to the same pressure, the flow rate of liquid and gas are different, resulting in different dynamic and static pressure to actuate the disc valve pulse: Due to the different temperatures of the condensate through the two series in series orifice Plate, sitting in the bipolar orifice between the different pressures, driving the valve action.
