ABSTRACT:
An I-type counterflow absorber for directly connecting with a piping system to absorb the impact force and noise resulting from water hammering in the piping system. It includes an outer tube, an inner tube, a valve member and a buffer mechanism. The inner tube forms a water passage with the piping system. The valve member is moveable and covers one end of the inner tube. The buffer mechanism is located between the inner tube and the outer tube, and has a damping chamber and an air chamber for absorbing the impact force and noise resulting from water hammering in the piping system. It can effectively protect the pumping device and piping end from water hammering damage.
