The pressure cooker doesn't show how to repair it.

1. Slowly deflate the pressure limiting valve. The main reason is that the pot is uneven, or the pressure limiting valve has been used for a long time, and the inside and the top are rusted. It is also related to the lack of riveting at the top. If there is scale in the pressure limiting valve, rinse it with alkaline water or washing powder water 1 time. The exhaust pipe is flat. 1 is caused by loose nut or rotten asbestos pad. If the nut is loose, it can be tightened in time; If the asbestos pad is rotten, it should be replaced with a new one. 3. What if the soluble tablet melts? You can cover the pot with a wet towel and put it down. After the pressure in the pot drops, open the pot and replace it with new soluble tablets. The gas in the pot is running out. This is because there are burrs on the edge of the pot, the apron is too wide and too thin, and the apron sealing line cutting is not up to standard, which will affect the sealing of the pot and cause the pot to leak. Sometimes this happens when the firepower is not strong.
