What is the description of the trap failure?

At present, the traps used in China are seriously polluted. According to statistics, at present, there are about 20 million traps installed in the national chemical system, of which only 10% belong to Taiwanese products. About 60% of the steam leaks are large, that is, the leak rate is more than 3%, and about 30% are serious failures.
, invalid.
     The so-called trap failure, that is, under the working condition, the hydrophobic kitchen loses its normal working ability. When the valve and the valve seat are in the closed state, the leaked steam is larger than the allowable range of the unit displacement, or the valve is stuck. If the displacement is less than the amount of condensate generated by the steam system, the water can be considered as hydrophobic. The valve has failed.

     For such a period of use, the parts of the steam trap are corroded, worn, and clogged with dirt, etc., and are not eliminated by simple repair. This situation should be updated.
