| 1. An automatic actuation apparatus for a valve body having a water inlet and a water outlet, comprising:
a valve member adapted for sealedly disposed between said water inlet and said water outlet to control water flowing from
said water inlet to said water outlet; and
a powering assembly, comprising:
a power generator,
a relief valve having a water passage extended along said valve member for communicating with said water outlet, and comprising
a valve stopper disposed at an opening of said water passage to close said water passage, and a resilient element disposed
in said water passage, wherein said resilient element has a biasing end coupled with said valve stopper and an opposed affixing
end coupled within said water passage for applying an urging force against said valve stopper to normally retain said valve
stopper on said opening of said water passage; and
an actuator driven to be rotated by said power generator to move said relief valve between an auto-operated closed position
and an auto-operated opened position, wherein at said auto-operated closed position, said valve stopper is sealedly retained
at said valve stopper to close said water passage for blocking said water passing to said water outlet, and at said auto-operated
opened position, said actuator is driven to rotate to contact with said valve stopper and to push said valve stopper to an
offset position from said opening of said water passage for allowing said water passing to said water outlet.
