Trap installation precautions

In general, traps are installed below the condensate drain device. However, if you want to install the trap higher than the condensate drain device, install the poppet in front of the trap so that the condensate can flow into the trap smoothly. Liftfitting: Also known as "lifting joint". When the condensate drain site is low, it can suck the condensate to a high point and guide it forward.

(2) Exit side recovery pipe

The diameter of the piping used to recover the condensate discharged from the trap should have a certain margin, at least to prevent the influence of steam hammer or pressure loss. In addition, when connecting the recovery pipe to a plurality of collector pipes (back pipes), a certain inflow angle should be created to facilitate the flow of the condensed water.

(3) When the outlet piping is flooded

When the condensate drains to the drain, if the drain pipe is directly extended into the water, the danger of condensate splashing may be caused. If it is necessary to be flooded, in order to prevent the water in the drain from flowing back to the trap when the steam is stopped, it is necessary to make a hole in the drain pipe or install a vacuum adjustment valve.

(4) Setting of the condensate collecting device

When a trap is installed in the steam conveying pipe, it is necessary to design a condensate collecting device.

In the early stage of ventilation and the fast flow rate, it can effectively collect condensate, which will help the trap to work better. If the condensate collecting device is not designed, it is easy to see that the condensed water is not discharged and garbage. Scale blocking entrance and so on.

(5) Recovery of condensate lines with different pressures

For condensate lines with different pressure conditions, the condensate recovery pipes must be designed for each different pressure, or flashlegs must be installed for recovery. Once the high-pressure condensate flows into the low-pressure recovery pipe, the condensate will evaporate again due to the temperature difference of the condensate, thereby generating noise. Steam hammer and other adverse effects.
