Claim:
An automate fluid flow control system for a fluid system having a fluid inlet, a fluid outlet, and a fluid chamber communicating between said fluid inlet and said fluid outlet, wherein said automate fluid flow control system comprises: a valve member adapted for being sealedly disposed within said fluid chamber to seal a flow of fluid flowing from said fluid inlet to said fluid outlet; a relief valve provided at said valve member for controlling said fluid flowing from said fluid chamber to said fluid outlet, wherein said relief valve has a fluid passage extended along said valve member for communicating said fluid chamber with said fluid outlet and comprises a valve stopper sitting on a top opening of said fluid passage to sealedly close said fluid passage for controlling said fluid flowing to said fluid outlet, wherein said valve stopper has an engaging surface; a power generator; an actuator driven by said power generator to control said relief valve between a closed position and an opened position, wherein at said closed position, said valve stopper is retained to sealedly close said fluid passage for blocking said fluid passing to said fluid outlet, and at said opened position, said actuator is driven by said power generator to contact with said engaging surface of said valve stopper and to drive said valve stopper to open said fluid passage for releasing a pressure within said water chamber to allow said fluid passing to said fluid outlet, wherein said actuator comprises a driving arm rotatably extended from said power generator towards said fluid passage and a pusher arm non-coaxially extended from said driving arm to said valve stopper for pushing said engaging surface of said valve stopper from said closed position to said opened position, wherein said valve member comprises a sealing platform arranged for sitting within said fluid chamber, a sealing diaphragm supported on said sealing platform for movably sealing at said fluid chamber to retain said pressure therewithin, and a retention member supported within said fluid chamber at a position above said sealing platform to block said sealing platform to be further lifted up when said pressure within said fluid chamber is reduced; a resilient element to apply an urging force against said valve stopper so as to retain said valve stopper at said closed position; and a knob operatively communicated said automate fluid flow control system defining an original position corresponding to said closed position, wherein when said knob is turned from said original position to drive said actuator to rotate correspondingly from said closed position to said opened position, said pusher arm of said actuator will push said valve stopper to unseal said fluid passage, wherein when said knob is turned back to said original position to drive said actuator to rotate correspondingly from said opened position to said closed position, said pusher arm of said actuator will stop pushing said valve stopper and allow said valve stopper to return to said closed position.
