Safety device for residual pressure reaction

It is a safety device that prevents the cover being opened after the completion of cooking in a state when the internal pressure is not completely discharged.

  • When there is internal pressure, the elevation pin remains stuck out to lock the cover.
  • When internal pressure is completely relieved, the elevation pin goes down to allow a user to open the cover.


  • When the pressure acting on the built-in diaphragm reaches a critical pressure, the safety pin associated with the diaphragm is rapidly displaced
  • The response speed at the threshold is fast and accurate
