How to choose low-pressure gas transmission and distribution system on the valve

First, the natural gas panic considerable prospects, large demand for olefin gas valve Natural gas is a very clever prospect of clean high-quality energy. Natural gas almost no smoke and sulfur dioxide emissions in the combustion process, carbon dioxide thanks to the amount is also much smaller than the burning of coal oil. With the emphasis on the environment and the sustainable development of ecology in our country's urban areas and the improvement of people's living standards, it is estimated that the proportion of natural gas in China's urban gas will increase from the current 33% to 66% by 2010. There are three gas-bearing areas in Sichuan, Shaanxi-Gansu-Ningxia and Xinjiang in China. In addition, there are good oil and gas displays in the western South China Sea, the Yinggehai Basin and the East China Sea. Coupled with the introduction of Russian natural gas in the future, the import of liquefied natural gas in the Yangtze River and Pearl River Delta regions, the supply of natural gas in our country will be guaranteed. The construction and planning of the "West-East Gas Transmission" and "Russian Gas Supply" will enable the cities and towns along the pipeline to be gasified. Among them, there is a great demand for valves for gas pipelines. As a valve manufacturer, the "West-East Gas Pipeline" The project is to transport natural gas east of Tarim to South East. The pipeline will be exported by the first round of the battle in Southern Korla, passing through Baihe Town, which ends in eight provinces of Xinjiang, Gansu, Ningxia, Shaanxi, Shanxi, Henan, Anhui and Jiangsu provinces. Pipeline full-length 4200Km, pipe 1016mm, gas pressure 10MPa, is expected by the end of 2004 across the board. In addition to the demand of Sichuan Province, the Sichuan-Chongqing natural gas in Sichuan Basin is not completely transported by the East East from Zhongxian via Hubei to Wuhan City, then Xinyang and Tarim Natural Gas to the east of Henan Province converge to the east of Shanghai with a total length of 811km and is planned to be completed in 2003 . The Changqing gas field in Shaanxi, Gansu and Ningxia has completed construction to the surrounding area of ​​the gas field by the end of 1998 and has now completed four natural gas transmission pipelines: 1, Jing-service military personnel to Xi'an, Baoji and Tongchuan; 2, Jingbian to Ningxia and Yinchuan; 3 , Jingbian to Beijing's long-distance pipeline, plans to extend eastward from Beijing to Shandong; 4, Jingbian to Yulin, Qingyu County. The "Russian Gas Supply South" will be carried out in line with the feasibility study agreement signed by China, Russia and the ROK on November 2, 2000 and plans to be completed in 2007 in Beijing, Tianjin and Hebei in the three northeastern provinces and the Bohai Rim region Province, Shandong Province and other provinces and cities. Introduction to Gas Supply System - Gas Transmission System and Gas Distribution System Natural gas is generally supplied to users through pipelines. At present, natural gas pipelines in many countries are criss-crossing with perfect facilities and construction activities of trans-national gas pipelines are exceptionally active. As mentioned earlier, the construction of gas pipelines in our country has two kinds of flexible supply modes, such as LNG transportation and compressed natural gas vehicles. The supply of natural gas in cities and towns generally takes pipeline from the gas pipeline to the gate station and has the functions of metering, pressure regulation and odor addition (some of them are stored), and the pipeline and gas distribution system with different pressure levels in the urban area Usually by the pressure in the dry pipe branch to the user pressure regulating station (box) for low pressure or medium pressure B gas for civil or boiler room and industrial users, urban gas pipeline design pressure P is divided into seven: high pressure gas pipeline A2. 5 times the high pressure gas pipeline A0.8 medium pressure gas pipeline A0.2 low pressure gas pipeline P This article describes only the gas distribution system, gas design pressure 0.4MPa, selection of the valve pressure up to 1.6MPa. Third, the gas distribution system with the valve on the original requirements of the valve installation location and use of places: Gas pipeline in the pressure on the underground valve room, the pressure regulator in front of low-voltage or medium-pressure B-level entrance of each user set the main valve points Section of the valve, each household and then burning the total or cooker pipe upload control valve, the total pressure regulator, the gauge should be installed before and after the valve.
