1. Pressure-limiting valve:
If the pressure inside is up to a regular working range, the
pressure-limiting valve will release extra steam (“a” is pressure-limiting valve).
2. Open-preventing valve:
It will rise when the pressure is above 4KPa. The steam will
be released from here when the steam-releasing hole is blocked.
3. Snuffle valve:
When the pressure-limiting valve and the safety valve are invalid, the
steam will come out from the snuffle valve to ensure safely usage (“b” is snuffle valve).
4. Opening knob:
To open the lid you must turn the knob.
IV. Special Characters
On the pressure regulating valve there are three different marks, they corresponds to
the following functions:
Steam releasing position
Low working pressure (60KPa)
High working pressure (100KPa)
The pressure regulating valve is equipped with pressure indicator with three positions. When
the first line goes up, it means that the pressure inside reached the low setting (60KPa). When
the second line goes up, it means that the pressure inside reached the high setting (100KPa).
When the third line goes up, it means that the working pressure is not normal. There are two
possibilities:
A: The temperature is too high; please turn the hot-plate to a lower setting.
B: The pressure limiting valve is blocked, or it is not placed correctly, you should check
whether the pressure limiting valve is blocked or not).
