I, on the basis of actual use conditions to determine traps steam import and export of pressure. Steam Traps of the entrance is the pressure valve at the entrance to the minimum pressure of work; trap exports is the pressure valve may work a maximum back pressure.
Nominal pressure of the trap, the nominal path, the maximum allowable pressure, the maximum allowed temperature to a maximum working pressure, the minimum working pressure, the highest rate of back pressure, the condensation of water displacement, and so should be in line with the steam pipe network of working conditions. Selection of steam traps should also be given to "trap rated equivalent to a displacement of the use of steam equipment condensate production multiplied by the rate chosen,"

Second, according to the conditions in the normal working hours to determine the possible condensation of water, multiplied by the correction factor, the control of the trap with a displacement of a select models of trap.
Third, the type of trap, the different structure of the principle, it should be based on different occasions to use the alternative form of the structure (see table 2)
Immediate discharge of condensate occasions, such as the steam turbine, steam pump, the head of steam lines and so on should not have used the cold trap, trap, such as pulse and temperature bellows-type trap
Condensate rated the largest displacement of less than 15%, should not be optional pulse-trap, because in such conditions, the steam of fresh drain easily from the discharge hole
Offices, schools, scientific research and residential areas around the annex, the need for a quiet environment, the noise should not be a big selection of hot power-trap, trap-temperature should be selected and the float-trap, because they slow, small impact
Outdoor work of the trap, should not be chosen in general mechanical traps, the need to use, there should be protection of antifreeze
Devices are not allowed to use gas condensate accumulation should be selected in a row to rule out the possibility of condensation of water traps, such as ball-trap
In the face of demands the removal of condensate, also requested in a timely manner does not rule out the possibility of gas condensate occasions, there should be selected drainage, dual exhaust features of the trap
In the steam pipe network, if required to work back-pressure condensate recovery, should use the high pressure trap, such as machine-trap
