What is the pressure of the domestic pressure cooker?

The pressure of pressure cooker is determined according to the weight of pressure cap and the strength of spring. When the manufacturer designs, the wall thickness of the pressure cooker can bear the pressure of 2kg, and the weight of the pressure cap and the strength of the spring are mostly designed between 0.5 and 0.8, so that the normal pressure cooker will never explode!

Therefore, the pressure of the pressure cooker is generally 0.5-0.8 kg.

If the pressure in the pot increases, the temperature will also increase, so when the pressure in the pressure cooker is 0.56 kg/cm2 = 0.55 Pascal, the boiling temperature of water is112.6℃; If the pressure is 1 kg/cm2 = 0.98 Pascal, the boiling temperature of water can reach 120- 12 1℃.
