Cookware corresponding to pressure relief valve:

1. Domestic single and double cookers use low-pressure valves

2. Commercial energy-saving cookers and general single-head fierce stoves use medium-pressure valves

3. High-pressure valves for fierce stoves in restaurants

4. Multiple fierce stoves are equipped with liquefied gas pressure regulators after high-pressure valves

Performance of pressure relief valves:

1. It refers to the adjustable range of the output pressure P2 of the pressure reducing valve, within which the specified accuracy is required. The pressure regulating range is mainly related to the stiffness of the pressure regulating spring.

2. pressure characteristics. It refers to the characteristic of output pressure fluctuation caused by input pressure fluctuation when the flow rate g is constant. The smaller the fluctuation of output pressure, the better the characteristics of pressure reducing valve. The output pressure must be lower than the input pressure-the fixed value is basically unchanged with the change of input pressure.

3. Flow characteristics. It refers to the persistence of input pressure-timing and output pressure changing with the change of output flow g. When the flow rate g changes, the smaller the change of output pressure, the better. Generally, the lower the output pressure, the smaller its fluctuation with the change of output flow.

Precautions for the use of gas stoves:

(1) Always check whether there is any air leakage at the joint of the gas pipeline (gas tank) of the stove, and use soap foam to wipe the important parts. If there are bubbles, it means air leakage, so it should be repaired in time.

(2) ignite first, then deflate, and then sit in the pan: the room should be ventilated, and the kitchen doors and windows should not be closed for a long time.

(3) If the gas tank is used, it should be placed upright in a place where it is easy to move, and it is forbidden to put it flat or upside down. The place where the tank is put should be cool, dry and ventilated, and there should be a certain distance between the naked flame and the radiator.

(4) When using gas, people should not leave for a long time, so as to avoid accidents caused by the wind blowing out the flames or the soup overflowing and dousing them. If there is air leakage, it must not be ignited to avoid explosion. It can only be used after the window is ventilated and repaired.
