The role of steam trap

     Effect

    1.The function of the trap and the use of steam using equipment only steam. In this kind of equipment will certainly be generated within the condensate, condensate become harmful fluids, but also mixed with air and other non condensable gas, a cause equipment malfunction and reduce performance reasons. In this case, trap the most important function of the following three aspects:

    (1).Can quickly eliminate the condensation of water.

    (2).To prevent steam leakage.

    (3).The exclusion of air and other non condensable gas.

     Bucket type

     Overheat steam or no condensed water situations, as well as the trap size too big occasions, is easy to appear the condensation water can not ensure that the bucket float, resulting in valve cannot be closed, spewing steam. Therefore, in the condensate fewoccasions, can not use a bucket.

     .Entrance side pressure declined drastically, condensation of waterinside the trap will again evaporated, so that the bucket buoyancydisappeared, resulting in continuous exhaust steam. Please be sure to pay attention to.

     Floating ball type

      Ball float type steam trap condensate was concentrated in thebody, therefore in the cold area must be used to prevent freezing phenomenon.

     Thermostatic type

     Superheated steam occasions easy failure, do not use on thisoccasion.

· thermostatic type, thermal type without heat treatment. The steamtemperature, unable to perceive the transformer room, unable toheat dissipation resulting hydrophobic valve cannot workphenomenon easy to heat treatment.

     Comparison of constant temperature and heat type

     Temperature characteristics

     The thermocouple type drain valve is lower than the saturated steam temperature 5~ 10 ℃ begins the work, thus preventing thedischarge of steam, can work stably in the standard pressure condition. Wax element type drain valve is working at a fixedtemperature. Thermodynamic type traps work basically independent of temperature.

Fluid Couplings

     Ventilation work

     Thermostatic type drain valve open state for the valve in theventilation early, shorter heating time ventilation.

Thermodynamic steam trap valve in the closed state during the early stage, although the design of micro crack is improved, but thetime of heating ventilation or longer.
