Through the technical research, six homes 11 to capture the key technology of alumina extraction process system of fly ash with high temperature valve etc.. The successful development of the valve will lay a solid foundation for solving the demand of control valves and industrial production of all kinds of specifications and uses for the industrial system of alumina extraction from fly ash.
CAP1400 ADS automatic step-down system valve, low pressure differential open check valve, large diameter electric gate valve
In March 12, 2017, the joint development of Sufa technology industry Limited by Share Ltd and the Shanghai nuclear engineering research and Design Institute of CAP1400 ADS automatic depressurization valves, low opening check valve, large diameter valve electric valve "three successfully passed the acceptance.
The three valve is first developed in China, reaching the international advanced level. It can be applied to CAP1400/CAP1000 and other nuclear power projects, and has good social and economic benefits.
Main steam isolating valve
In April 13, 2017, the main steam isolation valve of Fuqing No. 5 generating unit of Hualong No.1 successfully completed the factory acceptance. This indicates that "made in China" has achieved zero breakthroughs in the main steam isolation valve, the most important nuclear power valve manufacturing and application field.
The main steam isolation valve is one of the key equipment of the nuclear power plant. For the world's first "Hualong No. 1" the smooth construction, to create "Hualong No. 1" beautiful card, laid a solid foundation.
Deep water high pressure solenoid valve
In 2017 June, by the North China Aerospace Science and technology group of deep-sea expedition 11 from six hospitals bear BOP with high pressure solenoid valve successfully completed the test, product delivery.
Deep water solenoid valve in deepwater drilling operations in the direct control of deepwater BOP group started at the same time, long-term work in the 3000 meters underwater for a long time under low temperature and deep water, seawater corrosion, is a key equipment to ensure the safety and reliability of deepwater drilling, after the product is only the United States and Germany, few companies can produce. The Institute adheres to technological innovation and solves the problem of corrosion resistance of seawater solenoid valve in seawater medium. The solenoid valve product is successfully developed, and the production cost of products is greatly reduced, and the reliability of products is improved.
High voltage flexible DC transmission valve
In July 6, 2017, China XD Group belongs to electric power enterprises independently developed system - 800 thousand volt /5000 trillion Watt high pressure flexible HVDC converter valve smoothly through the insulation test and operation test, which marks the UHV HVDC flexible world's highest voltage level, the maximum capacity of the converter valve successfully developed.
The advent of this product has promoted the progress of China's flexible DC transmission technology and further consolidated our country's international leading position in this field.
LZ943WF-900LB-24 "adjustable flat gate valve, 24" FLJ941H900LB high pressure throttle cut-off valve and dark rod type flat gate valve for wellhead
In December 2, 2017, development of Jiangsu salt Valve Machinery Co. Ltd. LZ943WF-900LB-24 "adjustable plate gate valve, 24 FLJ941H900LB high-pressure throttle stop venting valve and wellhead with the hidden rod type plate valve three prototype of the new product through the valve localization of national new product identification.
The three new products have filled the gap in China and have reached the advanced level at home and abroad. They can be put into production in bulk by unanimously identifying new products, and will have broad market prospects in the future.
