1) The function of the pressure limiting device is that when the pressure in the pot reaches the working pressure during the heating process, the pressure limiting valve is exhausted through the venting hole to prevent the pressure from continuing to rise, to achieve the purpose of cooking, and the anti-blocking under the pressure limiting valve is provided. Cover to prevent food from clogging the pressure limiting vent.
(2) The safety pressure protection device is often a fusible piece. When the pressure exceeds the working pressure and the pressure limiting valve is not working due to clogging of the vent hole or other reasons, the fusible piece is fused through when the pressure is not more than twice the working pressure. Gas, to avoid damage to the pressure cooker, thus protecting the safety of the user, now many safety pressure protection devices of the pressure cooker have been changed to a spring structure, and the spring is exhausted when the pressure rises, which also acts as a pressure relief.
