Pressure cooker on the fire is very careful, especially not with a large fire. After heating, as long as the steam in the pot makes a large "hissing" sound from the exhaust pipe, you can reduce the temperature of the stove and keep the pressure limiting valve making a slight hissing sound until the cooking is complete. This is safe, time and fuel efficient. Similarly, never open the lid halfway during the heating process to avoid food bursting into heat.

If the float does not fall, it proves that there is still pressure in the tank, at this time, the air pressure interlocking device will play a safe role, the lid of the pot can not be opened, do not force to open the lid compulsorily, which is very dangerous. Before opening the lid, use chopsticks to press the indicator valve to expel the remaining air in the pot before opening the lid.
