It is suggested that the gap between the sealing ring and the pot cover should be tightly pressed every time it is used. In addition, after long-term use, the high-pressure sealing ring will age and lose its elasticity, resulting in poor sealing and air leakage of the cover. You can buy a new sealing ring and replace it.
The high-pressure valve can only float by enough steam, but if the cooking water is too little, the temperature in the pot rises too fast, and there is not enough time to generate enough steam, gas may be generated, and the high-pressure valve cannot float, resulting in air leakage. Then there is the phenomenon that the sealing valve is not set to the sealing gear but to the exhaust gear.

Matters needing attention in the use of pressure cooker:
1, when using, first carefully check whether the exhaust hole is clear and whether the hole under the valve seat of the safety valve is blocked by residual rice grains or other food residues.
2. Before cooking food, the handle of the pot cover must be consistent with the instructions of the pot body, otherwise the pot cover is not good, the pressure will not come up, or the pot cover will bounce up after the pressure comes up, which may easily lead to burns.
3. Never open the lid in the middle of the heating process to avoid food explosion. Do not remove the heavy hammer or pressure regulating device before confirming cooling, so as to avoid food splashing and personal injury. The cover can only be opened after natural cooling or forced cooling.
