A rapid air valve is provided to prevent an air hole from being locked by moving a float valve to an upper portion when rapidly exhausting air in a water pipe. A rapid air valve includes a float valve(30) floated on water of a body(10) connected with a water pipe. A floating valve(40) is connected with an upper portion of the float valve. An air hole of an air valve is locked by the upper portion of the floating valve. Air is continuously exhausted through an exhausting hole(41) of the floating valve to exhaust the air of the water pipe even though the floating valve locks the air hole because the float valve elevates when air rapidly flows inside from the water pipe.
