Abstract:
1. 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 the 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, and a valve controlling shaft coaxially extended from said valve member that said fluid passage is extended along said valve controlling shaft for communicating said fluid chamber with said fluid outlet; and a powering assembly, comprising: a power generator; and an actuator which 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 such that when said driving arm is driven to rotate by said power generator, said pusher arm is driven to push said valve stopper to unseal said fluid passage, such that said actuator is arranged to be driven by said power generator to move said relief valve between a closed position and an opened position, wherein at said closed position, said valve stopper is sealedly retained to close said fluid passage for blocking said fluid passing to said fluid outlet, and at said opened position, said actuator drives said valve stopper to unseal said fluid passage for releasing a pressure within said water chamber to allow said fluid passing to said fluid outlet without moving said valve controlling shaft; wherein the valve stopper has a flat side engaging surface to substantially engage with said actuator such that when said actuator is driven to rotate, said valve stopper pushes by said actuator at said side engaging surface to unseal said fluid passage so as to ensure an operation of said relief valve.
