Improper pneumatic valve steam traps capacity?

Steam energy-saving equipment company factory has learned that, when choosing hydrophobic pneumatic valve selection and steam using equipment must be suitable to the construction, use and operation conditions in the form of a hydrophobic pneumatic valve, at the same time, you have to choose a rate properly. If chooses the safety factor of undeserved, make steam capacity of hydrophobic pneumatic valve is too large or too small, will produce very bad consequences:










if the margin is too large, install and use the large pneumatic valve, steam trap also can produce the following disadvantages:



(1) steam hydrophobic increased the capacity of the pneumatic valve assembly cost;



(2) for intermittent operation of pneumatic valve, steam trap too much capacity to make hydrophobic pneumatic valve cycle lengthened, the average water holdup increases, the ability to reduce steam equipment;



(3) for continuous (like floating, hydrophobic, pneumatic valve, According to the proportion) Action of pneumatic valve, steam steamed hydrophobic due to the large pneumatic valve opening is small, the capacity of the pneumatic valve seat causes hair phenomena ( High velocity through the narrow gap, make use of corrosion on the contact surface and the groove) , make the pneumatic seat damage caused by the leakage;



(4) to shorten the life of hydrophobic pneumatic valve of steam.



on the contrary, if the margin is too small, can make the capacity of hydrophobic pneumatic valve used is too small, will produce the following failures:



(1) can not adapt to steam using equipment load variation; Make the operation efficiency significantly reduced;



(2) through the hydrophobic pneumatic valve water often achieve maximum limits, make the pneumatic valve and pneumatic valve seat prone to corrosion damage.



(3) the steam hydrophobic shorten the life of pneumatic valve.
