The pressure cooker shows its advantages only when it is used correctly and is durable. The use of the pressure cooker should follow the following methods. Its advantages lie in time saving and energy saving, while its disadvantages lie in the possibility of explosion and injury in case of incorrect operation or defects.

Pressure control safety device: it can automatically cut off power in case of exceeding the set pressure during use. Pressure relief safety device: when the pressure in the boiler exceeds the safety value due to the failure of the pressure limiting safety device, the pressure relief mechanism will work to automatically exhaust and relieve the pressure around the boiler to ensure that no accident of boiler explosion will occur. Pressure limiting safety device: when the pressure in the boiler increases to the upper limit, the pressure limiting vent valve will automatically exhaust and limit the pressure.
