Gas supply method for high-rise civil building with adjustable gas supply pressure

Abstract

The invention relates to a gas supply method for a high-rise civil building with adjustable gas supply pressure. The gas supply method comprises the following steps that a pressure curve P(t) matchedwith the gas consumption law of each time period is obtained; the pressure regulating equipment automatically adjusts the outlet pressure according to the pressure curve P(t), the pressure curve is set to 2150 Pa-2200 Pa in a gas consumption peak period, the pressure curve is 1700 Pa-2200 Pa in other time periods. The fuel gas is regulated by the pressure regulating equipment and then is conveyedto all the user stoves through a fuel gas pipeline; the pressure regulating equipment automatically adjusts the outlet pressure according to the pressure curve during use, so that the pre-cooking pressures of each user in each time period are within the running range value, a low-use-low-voltage regulator is not required, users of all floors in each time period can normally use the fuel gas can also guarantee, the safety of gas supply in a high-rise civil building is improved, and the operation cost is reduced.

Description

technical field [0001] The invention relates to the field of indoor gas supply, in particular to a gas supply method for high-rise civil buildings with adjustable gas supply pressure. Background technique [0002] In the indoor gas supply system, the "Code for Design of Urban Gas" GB50028-2006 stipulates in Article 10.2.1 that the rated pressure of the natural gas gas burner of civil low-pressure gas equipment is 2000Pa, and the allowable working pressure range of the stove is 1500Pa~3000Pa. For high-rise civil buildings, with the increase of floors, the greater the additional pressure, the outlet pressure of civil pressure regulating equipment is usually set to a certain fixed value, such as 2000Pa. Therefore, it is difficult for the outlet pressure of the pressure regulating equipment to meet the needs of users on the lowest floor whose pre-stove pressure is higher than the lowest pre-stove working pressure, and at the same time meet the needs of users on the highest floor...

AI Technical Summary

Problems solved by technology

However, in order to ensure the safety of gas use, it is necessary to carry out regular maintenance on each low-low pressure regulator at home, which has problems such as inconvenient maintenance and high maintenance costs.

If regular maintenance is not carried out, there may be a risk of equipment failure, bringing safety hazards to users
