How to use the pressure limiting valve of the pressure cooker, and what are the precautions when using the pressure cooker?

How to use the pressure limiting valve;

1. When the electric pressure cooker starts to work, the pressure limiting valve must be set in the sealing position;

2. The pressure limiting valve cannot be weighted or replaced by other items;

3. If the juice food (porridge, sticky food) in the pot boils, you can't immediately dial the pressure limiting valve to exhaust, otherwise the soup will be ejected from the exhaust pipe;

4. When pulling the pressure limiting valve to deflate, please don't put your hands and face near the exhaust pipe of the pressure limiting valve to avoid being burned by the discharged steam; ?

5. Pay attention to timely cleaning the pressure limiting valve, and check whether it is blocked before use to avoid explosion.

Matters needing attention in the use of pressure cooker:

1. Check the pressure limiting valve and float valve, check whether the pressure cooker can be buckled in place and whether the gasket on the cover is yellow. If you find a blockage, please clean it immediately. If you find your mouth tight, don't use it for the time being. If the buckle is not tight, it will leak. Take it for maintenance or stop using it. The yellow washer should be replaced.

2. Remember not to pack too much food, and leave a proper gap between the food and the pot. Before closing the lid, please make sure that the throttle valve is not blocked, and fasten the pressure cooker before ignition.

Don't turn on the pressure cooker in a hurry. Only after the high-pressure gas is completely released, that is, after the pressure cooker is cooled, can the lower limit pressure valve be taken and the cover be opened.

If the rice in the pot is hard, don't take it away by force, soak it in water, and then brush it with cloth or sponge to protect the protective film inside the pot. You can't brush it with steel balls. Once the protective film is brushed off, it is easy to stick to the pot and reduce the service life of the pressure cooker.

5. Air leakage, rust and pressure cooker deformation lead to poor sealing, and the pressure limiting valve is not ventilated. When the above situation occurs, the pressure cooker cannot be used.

6. The service time of pressure cooker is generally not more than 5 years, with 5 years as the upper limit. If the pressure cooker is used for too long, it will age and be unsafe to use. Remember not to use it over age.
