Pressure cooker with pressure-limiting valve control structure

The invention discloses a pressure cooker with a pressure-limiting valve control structure. The pressure cooker comprises a cover. A pressure-limiting valve component is arranged on the lateral side of the cover, and comprises an exhaust hole communicated with the cover in the thickness direction. A gravity-type pressure-limiting valve is arranged in an upper end gap of the exhaust hole in a sleeved mode, can only ascend and descend on an exhaust pipe axially and cannot rotate circumferentially. A pressure-limiting valve height adjusting step is arranged at the root of the exhaust hole rotationally in an encircling mode, and encircles the circumferential outer side of the exhaust pipe. Three pressure-limiting valve steps with different heights are arranged in the thickness direction of thecover sequentially, and the adjacent steps are in smooth transition. A step contact is arranged at the lower end of the pressure-limiting valve in a protruded mode, and can contact one of the pressure-limiting valve steps correspondingly.
