Problems solved by technology
[0002] There are many problems in the existing natural gas transmission and distribution schemes. First, the safety of gas supply needs to be considered. Usually, the sub-high pressure pipelines of gas supply facilities are generally installed in densely populated places. If there is a gas leak, it is easy to endanger people. ; What's more, the pressure of the pipeline network in natural gas is relatively small, and most of the pipeline network pressure is transmitted and distributed according to the calculated standard value, resulting in low pressure when the natural gas is transported to the low-pressure pipeline network, and cannot reach the user's stove; and the existing The pressure of the pipe network can not be adjusted by the user himself, which is very inconvenient to use

Embodiment Construction
[0013] Below in conjunction with specific embodiment, further illustrate the present invention, this embodiment implements under the premise of the technical scheme of the present invention, it should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention.
[0014] A sub-high pressure natural gas pipeline network transmission and distribution method, comprising the following steps:
[0015] (1) Calculate the total amount of natural gas in the pipeline network through data such as pipeline network speed and flow velocity, and calculate the total amount of natural gas required by users in the area to be distributed and the pipeline pressure required for natural gas to reach the required area;
[0016] (2) Set up sub-high voltage gate station and storage and distribution station, medium voltage gate station and storage and distribution station, and low pressure gate station and storage a...

The invention discloses a sub-high-pressure natural gas pipe network transportation and distribution method which comprises the following steps that the total amount of natural gas in pipe networks iscalculated through data such as the pipe network rate and the flow rate, and the total amount of the natural gas needed by users in regions where distributing needs to be conducted and the pipeline pressure needed by the natural gas for reaching into the regions are calculated. A sub-high-pressure pipeline can store the certain amount of natural gas, and the pressure of all levels of pipe networks is increased; the pipe network pressure value is increased through the gas coming pressure of the natural gas, thus, the using pressure of the users along the pipe networks is increased, and user requirements are easy to meet; and pressure adjusting devices of a transportation and distribution system are close to the users, thus, fluctuation of the pressure of the users in front of ovens is small, and the burning condition of the ovens of the users is improved.
Description
technical field [0001] The invention relates to the field of natural gas transmission and distribution, in particular to a method for transmission and distribution of a sub-high pressure natural gas pipeline network. Background technique [0002] There are many problems in the existing natural gas transmission and distribution scheme. First, the safety of gas supply needs to be considered. Usually, the sub-high pressure pipelines of gas supply facilities are generally installed in densely populated places. If there is a gas leak, etc., it is easy to endanger people ; What's more, the pressure of the pipeline network in natural gas is relatively small, and most of the pipeline network pressure is transmitted and distributed according to the calculated standard value, resulting in low pressure when the natural gas is transported to the low-pressure pipeline network, and cannot reach the location in front of the user's stove; and the existing The user cannot adjust the pipe net...
