What if the old Supor pressure cooker doesn't open?

The solution is as follows:

1. Turn the lid clockwise. If the lid moves, it means there is no air pressure in the pot. The main reason why the pot can't be opened is that it can't be stopped, which leads to the pot cover not being opened. Solution: you can find a hard object, press the check valve, push the check valve back and open the cover;

2. If the lid is rotated clockwise, it may be that there is air pressure in the pot and it must be cooled and released. Pressure relief methods: natural cooling, air cooling and boosting are generally adopted. If you have to use this method, you should pay attention to cutting the gas ejected from the top air outlet, so as not to let the hot air hurt people.

3. The main reason why the lid can't be opened is that the lid is not cleaned in time and there are too many foreign bodies attached to the lid. The residue in the pot cover should be cleaned in time and often to ensure that the pot cover is clean.
