Spirax Sarco FT14 steam trap is used for network and devices can automatically discharge condensate, air and other non-condensable gases, steam and water blocking valve leakage. Effective energy conservation, and effectively protect the steam pipes in other devices, such as valve and safety valve. Imported trap is used for steam heating equipment and steam pipes, can automatically exclude the use of equipment and piping in the steam condensate, air and other non-condensable gases, and to prevent automated valve steam leaks. Steam is widely used in industrial production and living facilities, the condensate produced by the process needs to be excluded by steam traps, but does not allow steam leaks. Depending on the import works, steam traps can be turned into the following types: mechanical type: relying on highly liquid condensate guard changes within the steam trap and actions, including: float: float a closed hollow sphere float upward exposure type: float for opening up the bucket open down float: float down the barrel for open thermostatic type: rely on liquid temperature changes and actions, including: bimetal: Original sensitive bimetal steam Pressure: Sensitive original bellows or cartridge filled with a volatile liquid internal thermal power type: relying on changes in thermodynamic properties of liquid and action. Disc: Because the same pressure, the flow rate of liquid and gas is different, different dynamic generated by the static pressure, the valve disc driven pulsed operation: the temperature of the condensate due to the different poles in series through the orifice plate, sitting between the two poles of different pressures shaped orifice plates and driven valve action. Many varieties of imported traps, each with different performance. Traps choice, should first elect their identity can satisfy the optimum operating steam heating equipment, before considering other objective conditions, so you need to select the trap is the correct and effective. Traps to be "identified" steam and condensate, can play a role in blocking air drainage. "Recognition" of steam and condensate based on three principles: the density difference, temperature difference and the phase transition. So on the basis of three principles are three types of traps: classified as mechanical type, thermal static type, thermal power type.
