Causes of pressure cooker explosion: excessive heating, improper lid closing, too high water level in the pot, too much food in the pot and aging of the pot body.

1, overheating

When the pressure cooker is heated, if the temperature is too high, the pressure in the cooker will be too high, leading to an explosion accident. Therefore, when using the pressure cooker, we must pay attention to the heating temperature and not overheat.

2. The lid is not covered properly.

When the pressure cooker is heated, the cover must be covered, otherwise the pressure in the cooker can not be effectively controlled, which will lead to an explosion accident. Therefore, when using the pressure cooker, be sure to close the lid correctly.

The water level in the pot is too high.

When the pressure cooker is heated, the water level in the cooker must be controlled within a certain range, otherwise the pressure in the cooker is too high, which will lead to an explosion accident. Therefore, when using the pressure cooker, we must pay attention to the water level in the pot, not too high.

There is too much food in the pot.

When the pressure cooker is heated, the food in the cooker must be controlled within a certain range, otherwise the pressure in the cooker is too high, which will lead to an explosion accident. So when using the pressure cooker, we must pay attention to the amount of food in the pot, not too much.

5, pot aging

The pressure cooker will age after being used for a period of time, which will lead to the decline of sealing performance, unstable pressure control and easy to cause explosion accidents. Therefore, when using the pressure cooker, we must pay attention to the service life of the pot body and replace the aging pressure cooker in time.
