随着城市燃气工业的迅速发展,燃气工程设计在各地都必不可少。本文就以西南石油大学教工区的燃气工程设计为例,对小区天然气管道进行布置、计算和研究。
从大范围来讲,庭院、小区燃气管网工程设计,首先要依据燃气设计规范、施工规范、消防规范、以及相应规范和手册进行;然后要结合地区地理、气候特点及各地天然气公司的运行规程等实际情况,从技术可行性、经济合理性出发,综合考虑进行设计。
本工程严格按照国家燃气规范,通过现场踏勘,依次进行庭院管网、引入管、立管、户内管线的设计;用AutoCAD2008软件绘制出小区天然气管道平面布置图、室内燃气管道平面布置图和楼栋燃气管道系统图。本文采用试算法进行了庭院和室内管网水力计算,确定出中、低压管道的管径,合理选用出调压器型号。还对小区然气工程施工技术要求进行了编写,统计出了设计所需的相应设备和材料数量。
为保证设计的合理性,文章还对城镇燃气的质量要求、小区燃气工程管线和设备的布置原则、设备的选型及管材的选择进行了说明。特别是对当前燃气工程设计中存在的问题进行了详细的分析并提出了解决方法。本设计出能反映出当前民用燃气的发展方向,对燃气设计的改进有着非常重要的意义。

Abstract
With the rapid development of city gas industry,the design of natural gas project is an indispensable part in the modern city. This paper based on the natural gas project of Southwest Petroleum University Staff Area to layout,calculation and research the natural gas pipeline in residential.
From a wide range of speaking, the design of garden, residential work, at first , based on design specifications, construction specifications, Fire Code, and the corresponding norms and manual; and bine the design with local geography, climate characteristics and the rules of the local panies. Taking the technical feasibility, economic reasonableness into account.
The graduation project is based on the national norms and standards of the city gas distribution. Through on-site spot survey, we designed the yard work, introduction of pipes, risers, the pipeline of the indoor; We used the AutoCAD software to draw the maps of area natural gas pipeline, indoor gas pipeline and gas pipeline system of the buildings; Through calculating the indoor garden and water work, the diameter of the mid-pressure and low pipeline can be designed; According to residents gas quantity to determine the models of voltage regulator, pleted the technical requirements of residential natural gas engineering description, statistic the corresponding equipment and the amount of material.
To ensure the design is reasonable, This article also describes the quality requirement
