How to adjust the pressure of liquefied gas pressure reducing valve

The adjustment of the liquefied gas pressure reducing valve is carried out by a spring bolt extending from the pressure reducing valve:

1, first unscrew the plastic cover on the pressure reducing valve, and you can see that there is a plastic bolt with a small groove on it, which can be turned with a screwdriver.

2. Then tighten or loosen the bolts as required.

When tightening clockwise (1), the output of the pressure-reducing valve is small, the gas pressure after ignition is low, and the flame is small.

(2) Unscrew the bolt counterclockwise, the output of the pressure reducing valve will be large, and the gas pressure will be high and the flame will be large after ignition.

Extended data:

superiority

(1) less pollution.

Liquefied petroleum gas is a kind of hydrocarbon, which is composed of C3 (C3) and C4 (C4). It can be completely burned without dust. The application in modern cities can greatly reduce the pollution caused by using coal and firewood as fuel in the past.

(2) High calorific value

The calorific value of liquefied petroleum gas with the same weight is twice that of coal, and the liquid calorific value is 45 65 438+0 85 ~ 45 980 kJ/kg.

(3) Convenient transportation

Liquefied petroleum gas is a gas at normal temperature and pressure, which can be liquefied into liquid or frozen to a certain temperature under certain pressure, and can be transported on land and water by train (or car) tanker and liquefied petroleum gas ship.

(4) Pressure stability

The pressure in front of the user's furnace of liquefied petroleum gas pipeline is unchanged, which is convenient for users to use.

(5) Simple storage and flexible supply.

Compared with the production, storage and supply of city gas, the storage equipment of liquefied petroleum gas is relatively simple. Filling stations can be stored in liquefied petroleum gas storage tanks, put in gas cylinders for users to use, or supply gas through pipelines through gas distribution stations and supply pipe networks. Small bottles can even contain butane gas, which can be used as hot pot fuel on the table.
