Methods to prevent explosion of pressure cooker
Before use, carefully check whether the air holes on the valve seat of the pot cover are unblocked and whether the safety plug is intact.
The food in the pot should not exceed 4/5 of its capacity. When closing the lid, it must be screwed into the slot, and the upper and lower handles should be aligned. When cooking, the upper pressure valve is closed when steam starts to be discharged from the air hole.
When the temperature rises to the point where the pressure limiting valve hisses loudly, the temperature should be lowered immediately.
When cooking, if you find that the safety plug is exhausted, you should replace it with a new fusible piece in time, and you should not block it with iron wire, cloth and other things.
