The invention discloses a throttle valve which comprises a throttle valve cavity body, a gear through hole seat and a rotating shaft, wherein the throttle valve cavity body is provided with an air inlet passage, an air outlet passage and a mounting cavity; the air inlet passage and the air outlet passage separately communicate with the mounting cavity; the gear through hole seat is rotationally arranged in the mounting cavity in a sealed manner, and separates the air inlet passage and the air outlet passage into an air inlet cavity and an air outlet cavity; an air guide cavity with an opening in the top is formed in the gear through hole seat; a plurality of pairs of air guide holes which are oppositely arranged and used for communicating the air inlet cavity, the air outlet cavity and the air guide cavity are formed in the side wall of the gear through hole seat; all the pairs of air guide holes are of different sizes; the rotating shaft is rotationally sealed in the air guide cavity; and an air guide passage used for communicating or closing any pair of air guide holes is formed in the rotating shaft. Airflow flowing hole diameters of the air inlet cavity and the air outlet cavity are selected by rotating a throttle valve gear knob, so that the airflow flowing size is controlled and throttling is achieved.
