First, the prospect of substantial natural gas, ene gas valve in great demand
Natural gas is a very clean high-quality prospects energy. Natural gas in the combustion process is not even the emission of soot and sulfur dioxide, carbon dioxide is far less than the amount offueled with coal oil. As China's cities and towns focus on the environment and ensure ecological sustainable development, to adapt to people's improved quality of life, estimated that by 2010, natural gas in China's cities and towns in the proportion of gas from the current 33% to 66%.
China has been in Sichuan, Shaanxi-Gansu-Ningxia, Xinjiang, such as the three major gas-bearing area, while the western South China Sea, Yinggehai Basin, the East China Sea waters, such as oil and gas shows have been good. Coupled with the introduction of Russian natural gas in future, the Yangtze River, the Pearl River Delta region, such as liquefied natural gas imports, China's natural gas supply will be ensured.
Under construction and planning of the "West-East Gas Transmission" and "South of Russia for gas," the cities and towns along the route will be gasification, gas pipeline valve which in great demand, as the valve manufacturer is promising "West Gas East lose "project is to the east of Tarim Lunnan gas transmission pipeline from the first round of the South Kuerle output, through Xinjiang, Gansu, Ningxia, Shaanxi, Shanxi, Henan, Anhui, Jiangsu Province, the end of eight of the crane to the town of Shanghai. Pipeline length of 4200Km, tube 1016mm, gas pressure of 10MPa, across the board is expected to run through the end of 2004.
Sichuan Basin province of Sichuan, Chongqing, in addition to the demand for natural gas, the end to lose by Zhongxian from the east by Hubei and Wuhan, and then north to the Xinyang Henan Province, the convergence of East and transmission of natural gas in Tarim to Shanghai, a total length of pipeline 811km, plan completed in 2003 .
Changqing gas field in Shaanxi-Gansu-Ningxia was completed by the end of 1998 to the field projects around the region, has now completed four natural gas pipelines:
1, Jing change the military to Xi'an, Baoji, Tongchuan;
2, Jingbian to Ningxia Hui Autonomous Region, Yinchuan;
3, Jingbian to Beijing's long-distance pipeline is planned to extend east from Beijing, Shandong;
4, Jingbian to Yulin, Yu Qing County.
"Russian gas for the South" will be China, Russia and South Korea in November 2, 2000 feasibility study on the signing of the agreement, pay close attention to the implementation plan completed in 2007 for three provinces in Northeast China and Bohai Sea region, Beijing Municipality, Tianjin Municipality, Hebei provinces, seven provinces and cities in Shandong Province.
Second, natural gas supply profile - gas systems and gas distribution systems
The general adoption of natural gas supply pipeline to the user, in many countries criss-cross the natural gas pipe network, facilities, planning cross-border gas pipeline are extremely active in the building activities. Have already referred in our country the construction of gas pipelines, in addition to natural gas supply pipeline, liquefied natural gas, and automotive vehicle compressed natural gas are two modes of supply more flexible.
Urban gas supply, the general received from the pipeline gas pipeline to the door station, with the measurement, voltage regulator, odorization functions (some are stored), in different cities and towns located within the pressure-level review of the gas pipeline system, gas distribution systems generally stem from pressure to control user access regulator Extension Station (me) during the low-voltage or medium voltage class B or gas boiler room for civilian and industrial users, urban gas pipeline design pressure P is divided into 7:
A2.5 times of high pressure gas pipeline High Pressure Gas Pipeline Gas Pipeline A0.8 in A0.2 low pressure gas pipeline P <0.01MPa
This article introduced the gas distribution system, gas design pressure 0.4MPa, the pressure valve selection of up to 1.6MPa.
Third, gas distribution system to the original requirements of the valve
The installation of the valve location and use of places: in the pressure gas pipeline located in the ground floor of the indoor valve, low-pressure regulator devices or pressure in front of B-class for each user set up the introduction of the total valve population, sub-valves, household and Then the total burning stove pipe, or load control valves, pressure regulator the General Logistics Department, the meter must be installed before and after the valve.
