Principle description
1. A pressure water tank shall be added in the piping system to avoid pipe rupture resulting
from overpressure of piping due to ambient temperature fluctuation and to prevent air
hammer generated in the pipe.
2. To avoid overpressure or underpressure in the pipe, a makeup water valve and a drainage
valve shall be added; when the pressure is lower than 0.6bar, the makeup water valve
will open to make up water automatically; and the drainage valve will open to drain water
automatically while the pressure is more than 5bar.
