How to remove the pressure limiting valve of pressure cooker? How to operate?

There is an arrow on the lid of the pressure cooker and an arrow on the handle below. After the two arrows are aligned, deflate the pressure cooker and press the handle. The specific operation method is as follows:

1. Align the two arrows of the pressure cooker. There is an arrow on the lid of the pressure cooker and an arrow on the handle below. These two arrows should be aligned.

2. deflate the pressure cooker. Put the lid of the pressure cooker on the pot. When the two arrows are aligned, deflate the pressure cooker.

Precautions:

① Pressure control safety device: During use, if the pressure exceeds the set value, it can automatically cut off the power supply.

② Pressure relief safety device: When the pressure limiting safety device fails, the pressure relief mechanism works, so that the inner periphery of the pot can be automatically exhausted and pressure relieved to ensure that the pot will not explode.

③ Pressure-limiting safety device: When the air pressure in the pot rises to the upper limit, the pressure-limiting safety valve automatically exhausts and limits the pressure.

④ Power-off memory protection device: it can automatically continue to set functions before power-off, when the power cord is disconnected, a new phone is connected or the power supply is turned on.

⑤ Temperature limiting safety device: When the temperature in the pot rises to the limit, the power supply will be cut off automatically.
