Hydrophobic pneumatic valve can not discharge condensate, hydrophobic pneumatic valve for a long time no response, pneumatic valve surface temperature drop, this is hydrophobic state of pneumatic valve cannot open.
the reasons for this failure:
1, filter or piping by impurities, stolen goods jams, water can't flow pneumatic valve steam traps. Must clean strainer, pipe and pneumatic valve in the dirt.
2, hydrophobic pneumatic valve to discharge the condensate quantity is very small time interval or action expertise, then change into hydrophobic pneumatic valve capacity is small.
3, not discharge the condensate drain pneumatic valve is hot, is steam or secondary steam generated when steam is condensed steam blocking phenomenon, the steam is gone. This is caused by steam drain pneumatic valve installation is unreasonable, the inlet pipe can't there is stranded in the condensate.
4, water hammer damage cannot rise, the water should be replaced new float.
5, pressure is too large. Pressure steam equipment for more than a hydrophobic pneumatic valve of high working pressure, the hydrophobic pneumatic valve to open it. Replace the higher working pressure of hydrophobic pneumatic valve or adjust the reduce the working pressure of steam equipment.
6, water heater coil in a vacuum, obstruction of emissions. In the heat exchanger and water between the pneumatic valve installation vacuum breaker.
how to distinguish (hydrophobic pneumatic valve failure, different methods of hydrophobic pneumatic valve judgment is different also, simple method requires very professional experience, hydrophobic pneumatic valve, of course, also have a lot of professional methods, which need some equipment. Now that you say is condensed water is serious, it is hydrophobic pneumatic valve undrained, or displacement is lower than the produce of condensation water, this can be very easy to see at the scene. But the cause of water hammer is serious and there are many, may be improper selection, installation is wrong, no filter or filter before hydrophobic pneumatic valve failure, caused by hydrophobic pneumatic valve plug.
