Correspondence between gas burner and pressure reducing valve

Corresponding to the range of pressure reducing valve:

1, domestic single and double stoves use low-pressure valves.

2. Commercial, energy-saving stoves and general single-ended stoves are medium-pressure valves.

3. The high-pressure valve is used for the kitchen stove in the restaurant.

4. LPG regulators are installed behind the high pressure valves of several fierce furnaces.

Pressure reducing valve performance:

1, voltage adjustment range. The adjustable range of the output pressure P2 of the pressure reducing valve requires the specified accuracy within this range. The pressure adjustment range is mainly related to the stiffness of the pressure adjustment spring.

2. Pressure characteristics. It refers to the characteristic that the fluctuation of input pressure causes the fluctuation of output pressure 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 basically does not change with the change of input pressure.

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

Extended data:

Matters needing attention in the use of gas stoves:

(1) Always check the gas pipeline (gas tank) joint of the cooker for air leakage. Soap foam can be used to wipe important parts. If there is air bubble, it means air leakage, and it should be repaired in time.

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

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

(4) When using gas, people should not leave for a long time, so as to avoid the wind blowing out the flame or the soup overflowing and dousing the flame, causing an accident. If there is air leakage, it must not be ignited to avoid explosion. Windows can only be used after ventilation and maintenance.
