Harbin Electric Power Group Valve Co., Ltd. (hereinafter referred to as the H-valve) on behalf of China's 350MW supercritical unit valve, a few days ago in Jiangxi Ruijin power plant water supply pipe valve outlet project won the bid at one stroke, marking China's valve manufacturing industry has been among the advanced ranks of the world . According to the main person in charge of HEC, 350MW supercritical units such as the advent of five series of valves, not only to achieve an important breakthrough made the first set, but also ended our long-term dependence on imported high pressure valve in the history of the project. Not long ago, Harbin Electric Valves developed boiler supercritical unit supporting supercritical steam and water cut-off valve, check valve, large-diameter gate valve, hydraulic test plug valve, full-size safety valve and other five series of valves passed the China Machinery Industry Federation Organization of product identification and technical appraisal, appraisal, Hwasuo supercritical series of valve design and manufacture of advanced technology, design parameters to meet the requirements of the use of supercritical thermal power units, the data is complete and complete, reliable data, to fill the gap, to the international similar products Advanced level, marking the level of China's valve design and manufacturing leapt to a new level. Ha electrical valve construction in 1954, has been in the valve industry through a long road of more than 50 years of development. In 1985, HEC introduced Japan's Okano valve technology to design and manufacture a full range of safety valves and other high quality products through digestion, absorption, perfection and improvement. In 1990, HITO began mass production with the initial production of 50 Taiwan, the development of 450 units in 2007; valve production from 1990 annual output of 300 tons to 3,000 tons in 2007; production value from 10 million yuan in 1990, reaching 350 million yuan now. In 2003, when I blocked the technology in foreign countries, HECP took the initiative to carry out research and development work on the valves of the supercritical thermal power units of the State Development and Reform Commission and took out the first supercritical plugging valve in China in 2004 and the Yuhuan Millions of kilowatts ultra-supercritical unit coupled with the globe valve, check valve. Subsequently, the full amount of safety valves, large-diameter gate valve have also been successfully tested. HEC's growth and development have been highly valued by HEC Group. In order to make itself bigger and stronger and make new contributions to the country's electric power business, HEC Group reorganized HEC in 2007, Reform and reform, making it a self-employed, self-financing, directly facing the market of corporate enterprises. After the reform of Ha-valve even more powerful, and constantly climb the commanding heights of the valve industry, have developed a full-scale supercritical safety valve, gate valve, check valve, check valve, plug valve, of which the first two series passed the national technical appraisal, Three series passed the national product appraisal. At present, Haadian Power Group Valve Company has supplied more than 3,000 sets of supercritical steam and water supply stop valves, check valves and hydraulic test plug valves to more than 40 supercritical unit boilers of more than 20 domestic power plants. Unit operation shows that the performance of this series of products is stable, the parameters of the indicators have reached the design requirements, fully recognized by the user. In addition to being recognized by many domestic customers, the company's products are also favored by foreign customers and are now exported to India, Myanmar, Vietnam, Pakistan and other countries.
