Drain Valve summary

Steam trap is used in the steam pipe network and equipment, can automatically discharge condensate water, air and other non-condensate gas, and prevent the leakage of water vapor valve.The trap plays the role of steam blocking and drainage in the steam heating system. Choosing the proper trap can make the steam heating equipment reach the highest working efficiency.In order to achieve the ideal effect, it is necessary to have a comprehensive understanding of the working performance and characteristics of various types of traps.
According to the different working principle of the trap, it can be changed into the following types: mechanical type: action depending on the change of the height of the condensate water in the valve.Thermostatic type: depending on the change of liquid temperature and action.Thermodynamic type: depending on the change of the thermal dynamic properties of the liquid and action.


Drain Valve Choose the standard

  1. Can accurately exclude condensate water;
  2. No leakage of steam;
  3. Having the ability to exclude air;


Drain Valve Anti-freezing measures

1.Do not select an oversized trap.
2.Keep trap drain line as short as possible.
3.Bend trap drain line downward to speed up gravity drain.
4.Heat trap drain line and condensate return line.
5.When the condensate backwater pipeline is exposed to atmospheric conditions, a heat tracing pipe should be considered.
6.If the return pipe is raised, the vertical drain line shall be adjacent to the drain line above the return catch and shall be insulated with the trap drain line.
