At present, there are 3 kinds of natural gas regulating and supplying methods commonly used in gas supply enterprises, such as building voltage regulation, regional voltage regulation and household pressure regulation.
Through the above technical and economic comparison, the following factors should be considered in the design of gas supply network in the courtyard gas supply network.
1) high rise single building, if through the calculation of additional pressure head can not satisfy all the burning equipment near the rated working condition near the rated working condition, we should choose middle pressure to enter the household and divide the household pressure mode. If the other 2 ways are selected, all of the burning appliances can not meet the working state of the rated Ding condition and the technical is poor.
2) multi-storey single building, the building can be used to regulate the air supply mode, so compared with the other 2 ways, it can greatly reduce the total cost in the life period, and at the same time, it can keep the pressure stable under the rated flow, and the technical property is better.
In a word, the above 3 kinds of air supply modes have their advantages in both technology and economy. They are suitable for different places, and we should try to give consideration to both technology and economy when choosing the mode of regulating music supply. Otherwise, priority should be given to technical factors. With the continuous improvement of the technical quality of the indoor voltage regulator and the continuous reduction of the cost, in the high rise single building, the partial pressure regulating mode is the most ideal gas supply mode, and it will become the mainstream of the future development of the pressure regulating mode of the urban gas community.
