The valve industry plays an important role in the development of the national economy as an important part of preparing for manufacturing. As there is still a gap between China's domestic valve manufacturing industry and the international advanced level, many high-parameter, high-temperature, high-pressure, high-pound critical valves have always depended on imports. In order to promote the localization of valves, the State Council issued the "on the acceleration of the rejuvenation. After several opinions of the equipment manufacturing industry, the relevant national departments have successively made a series of major deployments according to the requirements of the country for major equipment localization, and are led by the National Development and Reform Commission. Together with China National Machinery Industry Association and the China General Machinery Industry Association, Deployed and formulated the valve localization program for major equipment in related fields, and coordinated with related departments several times, and now the localization of valves has formed a consensus in the domestic valve industry.
After 20 years of research, design, manufacture, and users' joint efforts in recent years, joint research has been fruitful. In the 'West-East Gas Transmission', 'South-to-North Water Diversion', 'Three Gorges Water Control Project', Million-kilowatt nuclear power unit, one-million-ton ethylene renovation project, supercritical and ultra-supercritical thermal power unit, oil and gas pipeline transportation, coal chemical industry, large-scale ships, and municipal wastewater In areas such as processing and major engineering equipment and nuclear power, petrochemicals, metallurgy, and power stations, in addition to a small number of high-parameter safety valves and regulating valves that need to be imported, localization of valves has been realized, which has changed the situation in which key valves of major equipment are permanently controlled by foreign countries. . And strive to achieve 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 China's valve manufacturing industry in the forefront of the world.
Starting from scratch, accelerating the pace of localization of valves The domesticization of Chinese valves has always been a long way to go. At the beginning, China advocated the localization of valves. It was not plain sailing and met with resistance at all levels. It was more controversial. After the experts of the older generation valve industry and some scientific research departments of the nuclear industry have tackled problems and coordinated efforts, domestically-made ones and resolutely domestically-made ones will try their best to wipe the ball in the localization to save foreign exchange for the country.
The localization of China’s valves was nothing at all, starting from scratch, and starting from localization in nuclear power plants and nuclear chemicals, as well as petrochemical equipment, in the 1980s, the first 600,000 nuclear power units related to engineering key projects were captured, and later When Qinshan Nuclear Power Station was engaged, Ningbo Valve Factory, as a pilot enterprise for the localization of valves for nuclear engineering fittings, contributed to the localization of valves. After the reform and opening up, China increased the localization of valves. With the continuous improvement of the manufacturing technology of the valve industry, many companies used the advanced resin sand molding line to produce casting blanks. The chemical composition of the castings was analyzed by a direct reading spectrometer. Cobalt 60 gamma ray is used to detect defects in castings; forging uses advanced technology such as tire die forging and multi-directional die forging. After entering the 21st century, the pace of localization of the valve has accelerated, and there have been achievements in the localization of major projects.
After issuing the "Several Opinions on Accelerating the Revitalization of the Equipment Manufacturing Industry", the State Council led the equipment manufacturing industry to revitalize in an all-round way. For this reason, the National Development and Reform Commission, the China National Machinery Industry Federation, and the China Association of National Associations and other national authorities have long proposed the plan to gradually realize the nationalization of major equipment and valves during the 'Tenth Five-Year' and 'Eleventh Five-Year' periods, which proposed the realization of millions of kilowatts. The key valves of nuclear power plants and the localization of valves for large-scale ethylene equipments of one million tons were introduced into key technologies and self-developed, and many concessions were given to regulations and policies. As a result, related valve companies seized the opportunity to take the initiative to make the country Localization of valves. Consensus was formed up and down, and localization of valves made gratifying progress.
Significant progress has been made in the localization of nuclear power valves. Key valves of nuclear power plants are important equipment for nuclear power plants. For a long time, they have mainly depended on imports. Foreign countries have always imposed a technical blockade on China in order to earn high profits, which has also become a bottleneck restricting the localization of nuclear power in China. one. The development of domestic nuclear valves started in the early 60s. After decades of efforts, China has formed a large-scale nuclear valve design, experiment, manufacturing, and testing capabilities, and provided a large number of nuclear-level valves for Qinshan Nuclear Power Station Phase I and Phase II construction. It has made important contributions.
