ABSTRACT:
A bladder surge tank includes a liquid port, and a bladder disposed therein for providing a surge absorbing interface between liquid and pressurized gas within the tank. The bladder surge tank can be horizontally or vertically oriented. In a horizontal embodiment, the surge tank includes a nozzle system disposed horizontally therein that is separate from the liquid port and that is integrally joined to the interior wall. Such nozzle system includes a nozzle member positioned between the liquid port and the bladder, and comprises a plurality of perforations disposed therethrough. In a vertical embodiment, the surge tank includes a nozzle system disposed vertically therein that is part of the liquid port and that includes a nozzle member having a plurality of perforations disposed therethrough. In both embodiment, the perforations define a total area that is greater than a total area of the liquid port, and the perforations are distributed throughout the nozzle member such that liquid entering the tank body through the liquid port is dispersed uniformly into the tank body.
