Vertical Pressure Tank
Pressure tank used in closed water circulation system, and play the role of the balance of water and pressure, to avoid safety valve frequently open and frequent replenishment of the automatic water valve. Expansion tank to play the role to accommodate the expansion of water, but also played the role of the makeup tank, expansion tank filled with nitrogen, to a larger volume to accommodate the expansion of water, high and low pressure expansion tank itself pressure parallel to the regulator system replenishment. Device control are interlocking reaction, automatic operation, the pressure fluctuation range, safe, reliable, energy saving, good economic effect.
