The appearance of the float valve of the electric pressure cooker is shown in the following figure:

The float valve is an important device for sealing and safety. Generally, the float valve is in a falling state. When the pressure in the pot reaches a certain level, the pressure will jack up the float valve. When the float valve rises, it will jam a safety knob when the lid is opened. By deflation, the pressure in the pot will be reduced, and the float valve will fall down after the pressure in the pot drops.

Note:

Before opening the lid of the electric pressure cooker, it is necessary to make sure that there is no air pressure in the cooker, then remove the pressure limiting valve to ensure that there is no air pressure in the cooker before opening the lid, or it can be forced to cool with cold water to reduce the pressure in the cooker, and then open the lid when there is no gas discharged from the cooker body.

pressure cookers in the market all have the safety protection of opening and closing the lid. For example, when there is air pressure in the cooker, the safety lever is in the rising stage, and then the lid cannot be opened according to the normal use method. When there is no air pressure in the cooker, the safety lever is lowered, and the lid can be opened safely. When exhausting, keep your hands or face away from the exhaust port to avoid burns.
