DSD

There are 6 safety sets on this  model: 
⭐1. Pressure limited valve: it has 2 levels of working pressure,low level is 60 kpa and high level is 110 kpa,

you can use different level by different foods ,moreover it can limit the working pressure to 90 kpa.
⭐2.Safety valve:  The function of the safety valve is to automatically replace the exhaust function of the

pressure limiting valve when the pressure limiting valve fails and the pressure in the pot exceeds the

safe range, reducing the pressure in the pot to the safe range, and the safety valve has an additional

stop valve function, when the pressure in the pot, the safety valve will automatically rise to prevent the

user from opening the pot in the dangerous environment of pressure.
⭐3.Stop rod:It can automatically detect the pressure in the pot. When the pressure in the pot is lower than

the safe opening pressure (4kpa), the valve stem will fall and the lid can be opened.
⭐4.Snuffle valve: This is a safety device to replace the old safety window, when the other valve fails and the pressure in the pan reaches 150kpa,

it automatically springs up and drains all the pressure to ensure the safety of the user
⭐5.Clamp:fix the lid and pot body to prevent the lid and body from looseing the connection.
⭐6.Rotary knob：it cant be close when clamp hasnt puted on right place yet .
