According to reports, in recent years, China's boiler main engine technology is developing in the direction of supercritical and super-supercritical. The main domestic boiler manufacturers have realized the introduction of supercritical and ultra-supercritical boilers, but the valves as supporting products have not been able to take Trains with high-speed development of Power Station boiler technology. High import prices limit the development of ultra-supercritical coal-fired units. At present, the domestic supercritical and ultra-supercritical unit supporting valves have long relied mainly on imports, and thus have become one of the bottlenecks restricting the localization of supercritical power station units in China. The successful manufacture of supercritical critical valves has solved the situation that many high-end supercritical valves rely on imports for many years.
In the face of the blockade of valve technology by foreign companies, Haguo Valve has undertaken the task of “Development of Localization of Supercritical Unit Valves†issued by the National Development and Reform Commission through the Machinery Industry Federation, and in 2004 developed the first supercritical plugging valve in China. In 2005, it successfully developed and tested the shut-off valves, check valves, full-size safety valves and large-diameter gate valves for the Yuhuan million-kilowatt ultra-supercritical unit. At present, the No.1 unit of Huaneng Yuhuan Power Plant supporting high-end valves has been successfully connected to the grid. This indicates that China has mastered the most advanced thermal power generation technology in the world--super-supercritical thermal power generation technology, and also enables China's power generation equipment manufacturing capability and technology. The level has reached a new level.
At present, Haguo Valve Company has equipped more than 500 supercritical steam and water supply shut-off valves, check valves and hydraulic test plugs for 28 supercritical unit boilers of 21 power plants such as Hegang, Wangqu, Yuhuan and Xiangyang. valve. The operation of the unit shows that the performance of this series of products is stable, and all the parameters of the indicators have met the design requirements, which has been fully recognized by users.
Haguo supercritical high-end valve design and manufacturing leap to a new level
High-end valves, such as steam and water supply shut-off valves, check valves, hydraulic test plugging valves and supercritical units, which are independently developed by Harbin Haguo Valve Co., Ltd., are equipped with full-size safety valves and large-diameter gate valves. Appraisal by the Expert Appraisal Committee of China Machinery Industry Federation. The experts at the meeting agreed that the Haguo Supercritical Series valves have reached the advanced level of international similar products. The products have reliable performance, novel and reasonable structure, and suitable materials. They are domestic leading products and can completely replace imported products. It marks that China's high-end valve design and manufacturing level has leapt to a new level.
