城市小区燃气工程设计毕业(设计)名师资料合集（完整版）资料(可以直接使用，可编辑优秀版资料，欢迎下载）摘要城镇燃气化是城市现代化的重要标志之一。城镇燃气在发展生产、提高人民生活水平、节约能源、减轻污染、改善环境等方面起着重要作用。本设计主要是针对开发区进行燃气管网的规划，该设计采用天然气为气源，燃气管道主要采用钢管。首先根据城市的面积及人口情况对开发区的燃气需用量进行确定，然后根据用气量及规划要求进行管网设计。在设计燃气管网时，应全面考虑经济、技术等方面因素，选择经济合理的最佳方案。因此本设计选用了中压一级管网系统。根据管网的布置和流量，经过水力计算的一系列步骤确定管径；再将管径作为已知条件，再选取调压设施以及用户燃具后满足供应的压力要求，设计具有一定的技术性和经济性。关键词：天然气管网用气量管径AbstractUniversalityofGasincityisanimportantsignofthemodernizationofcity.Inthedevelopmentandproductionofcity,improvinglivingstandards,energyconservation,reducingpollutionandimprovingtheenvironment,gasplaysasanimportantrole.Thethemeofthispaperistodesignthegasnetworkinthedevelopmentzone,takingthenaturalgasasthegassource,thesteelpipeasthemaingaspipeline.Firstly,accordingtothecityareaandthedemographicsituationofthedevelopmentzonetodeterminetheamountofgasneeded;andsecondlytodesignthenetworkaccordingtothegasconsumptionandtherequirementsoftheplan.Inthedesignofgaspipelinenetwork,theeconomic,technologicalandotherfactorsshouldbeconsideredComprehensively;finally,choosethebesteconomicalsolution.thereforethisdesignhasselectedcenterpresseslevelofpipenetworkssystems.Intheabovepipenetworksystem,usedtheregiontoadjustthepressuretostandtotheregionairfeedway.Accordingtopipenetworkarrangementandcurrentcapacity,processwaterpowercomputationaseriesofstepsdefinitecaliber;Againthecalibertookthedatum,afterselectstheaccenttopressthefacilityaswellastheuseragainburnshassatisfiesthesupplythepressurerequest.Thedesignhastheverygoodtechnicalnatureandtheefficiency.Keywords:TheNaturalgasThepipenetworkGasconsumptionDiameter目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc294028129"第一章绪论PAGEREF_Toc294028129\h1HYPERLINK\l"_Toc294028130"1.1概述PAGEREF_Toc294028130\h1HYPERLINK\l"_Toc294028131"1.2自然地理环境概况PAGEREF_Toc294028131\h1HYPERLINK\l"_Toc294028132"地理位置PAGEREF_Toc294028132\h1HYPERLINK\l"_Toc294028133"气候条件PAGEREF_Toc294028133\h2HYPERLINK\l"_Toc294028134"1.3设计原始资料PAGEREF_Toc2
