Ball Valve,Ball Valve Information

Valve industry in national economic development as an important part of preparing the manufacturing sector, play a very important role. As the level of our domestic and international ball valve manufacturing industry is still a certain gap between the advanced level, a lot of high parameters, high temperature and high pressure, high pound has been the key to the valve of the original imported, in order to urge the localization of the valve, the State Council issued ” equipment manufacturing industry to speed up the revitalization of a number of opinions “, the national authorities made in accordance with pressure washer requirements of major equipment, has made a series of major plans, led by the National Development and Reform Commission, China Machinery Industry Federation and the China General Machinery Industry Association along with the deployment of major equipment developed for the relevant areas of the valve domestic programs, and coordination with relevant departments several times, and now the valve domestic valve industry in China has formed a consensus.

After 20 years, especially in recent years, launch x431 research, design, manufacture and joint efforts of customers combined, joint research, has been fruitful. In the “Natural Gas”, “South”, “Three Gorges” million-kilowatt nuclear power plant, reconstruction million tons of ethylene, supercritical and ultra supercritical thermal power units, oil and gas pipeline, coal chemical industry, large vessels, the city sewage treatment projects and other major engineering equipment and nuclear power, petrochemical, metallurgical, power plants and other fields, in addition to a small amount of high-parameter safety valve and control valve to be imported, the achievement of the localization of the valve, thus changing the material and equipment subject to long-term key valve foreign situation. And try as much as possible in the short term major projects and key valves to achieve localization, or part of the realization of localization, so that the valve manufacturing in China to lead the world.

Valves made from scratch to accelerate the pace of China’s localization of the valve has always been an arduous task. Promote localization of the valve of the original, not easy, also encountered layers of resistance, more of a dispute. After the older generation valve industry experts and the nuclear industry sub-sector research and coordination of scientific research, can be used domestically, with domestic firm, in the localization of walking a fine line as far as possible for the roller bearing country to save foreign exchange.

Localization of the valve is nothing original, and start from scratch, and from nuclear power plants and nuclear chemical, and petrochemical equipment, based on the localization of the beginning, in the 80′s 60 million capture of the first nuclear power plant a key project on the project, and later engaged in Qingshan Nuclear Power Station, the Ningbo plant as a nuclear engineering valve pipe valve localization of pilot enterprises for the localization of the valve to make a contribution. China’s reform and opening up efforts to increase localization of the valve, the valve industry, with the rising level of manufacturing process, many companies using advanced resin sand casting off the production line blank box modeling, casting chemical composition using direct-reading spectrometer for wiper blade analysis by casting the rays of cobalt 60γ defect detection; forging die forging and using multiple fetal and other advanced technology to the forging. In the 21st century, accelerating the pace of localization of the valve, in the localization of major projects with performance.
