Hydrophobic pneumatic valve selection of technical parameters to consider

, using the water vapor condensation equipment load and load characteristic using steam discharge to the device and launch device production batch continuous production equipment. In the less load in the continuous operation of the condensate drain relatively stable; Batch production factory, large amounts of emissions necessary time each day to start the air and a lot of condensed water. When the choice must take into account the load characteristics of steam using equipment. , the highest working pressure steam condition, the highest working temperature and working pressure range, to the actual operating conditions of saturated steam or superheated steam, ability to trap trap setting output capacity of actual x or higher safety factor, safety factor selection based on the following reasons, the choice of pneumatic valve steam traps, safety factors must be considered. The choice of safety factor can be found in the table 'steam drain pneumatic valve safety coefficient of advice' and trap plant selection of instructions. （ ） Steam drain the ability of the pneumatic valve is a continuous discharge condensate discharge, and almost all of the steam in the practical work hydrophobic pneumatic valve is intermittent discharge. （ ） Equipment used steam capacity is the normal operation of the equipment, the condensed water discharge, and the device start early, condensate oil production is much higher than normal operation. （ ） Some heating equipment of intermittent production, each device in the water, start the initial setting. （ ） Equipment required for line pipe condensed water back to the recovery of the elevator. （ 5) Personal steam leakage fault trap back pressure increases the back-end trap, trap emissions.
