According to the current international situation and the demand for energy development in China, it is more urgent to further promote the localization of cryogenic valves in the field of air separation and natural gas liquefaction. China General Machinery Industry Association plans to organize the localization of low temperature valves based on the design and manufacturing requirements of 100,000 cubic meters / hour air separation plant and 3 million tons / year of liquefied natural gas plant valves.


July 20, 2018, a seminar on localization of cryogenic valves was held in Beijing. The meeting was chaired by Zhang Zonglie, vice president of China General Machinery Industry Association. Huang Wei, president of China General Machinery Industry Association, and honorary president Yan Yongbin, deputy Secretary-General Song Yinli and Xu Jianping attended the meeting. The meeting invited Sinopec Beijing Design Institute Qiu Ping, Ke Songlin, Sinopec Guangzhou Design Institute Jiang Wanjun, Sinopec Ningbo Design Institute Wang Lanxi, China Ryukyu Engineering Company Jia Qiyue, Hangyang Group Design Institute Zhou Fenfang, Hefei General Machinery Research Institute Zhang Jiwei and other experts attended meeting. Dalian Dagao Valve Co., Ltd., China Nuclear Su Valve Technology Industrial Co., Ltd., Jiangsu Shentong Valve Co., Ltd., Chengfeng Valve Group Co., Ltd., Wuzhong Instrument Valve Co., Ltd., Datong Mutual Group Co., Ltd., St. Bole Valve Co., Ltd. Hangyang Pump & Valve Manufacturing Co., Ltd., Jiangsu Yi Valve Co., Ltd., Dongyi Valve Manufacturing (Nantong) Co., Ltd., Dalian Henry Measurement and Control Instrument Engineering Co., Ltd., Zhejiang Yongsheng Technology Co., Ltd., Wuxi Yadi Instrument Co., Ltd., Tianjin Baili Zhanfa Group Co., Ltd., Shanghai Kaigong Valve Co., Ltd., Lanzhou High Pressure Valve Co., Ltd., Shenjiang Valve Co., Ltd., Xi'an Pump and Valve General Factory Co., Ltd., Shanghai Kaiweixi Valve Co., Ltd., Bethel Valve Group Co., Ltd. The main technical leaders of Jiangsu Jiulong Valve Manufacturing Co., Ltd. and other companies participated in the discussion of technical specifications and test programs.


Huang Wei, president of China General Machinery Industry Association, gave a speech on the background, situation and significance of localization. She pointed out that since 2006, the National Energy Administration and the China Communications Association have been continuously promoting the localization of major equipment, and have achieved many achievements, but there are still some key valve technologies that need to continue to overcome. Many ministries have recognized the importance of localization, but the implementation of specific work still needs to be done by associations and enterprises. In the process of localization, enterprises need to make great efforts. Sometimes the localization of some products may encounter technical difficulties, but the real demand is not large, and it needs to be balanced in the interests of enterprises and social interests. At the same time, President Huang Wei proposed: Although there are many difficulties in promoting localization, we have the foundation and determination to do localization work. Through this meeting, we hope to select some enterprises, break through key technologies, and promote low-temperature valves. Work.
The meeting focused on the low temperature and high pressure regulating valve, high pressure oxygen regulating valve, low temperature ball valve, low temperature axial flow check valve, low temperature butterfly valve technical specifications and prototype test outline, the drafting unit's person in charge introduced the main terms, experts and participants The technical leaders of the company jointly discussed, some key enterprises in the valve industry have been tackling the problem, and the progress of the research and the experts of Sinopec Design Institute also exchanged the progress. After repeated discussions, the technical specifications of the above five categories of products were finally determined. And the test outline.
After the discussion, Zhai Yongbin, honorary president of China General Machinery Industry Association, made a concluding speech. He emphasized that the localization of valves such as LNG should adhere to the principle of combining production, learning, research and use, and it is possible to consider establishing an industrial alliance according to the situation. Qiu Ping, representative of the Beijing Design Institute of Sinopec, made a speech on behalf of the experts of the conference user. He expressed confidence in the localization of the valve. Under the leadership of the association, he will actively participate in the research of LNG cryogenic valves, and make efforts to realize the localization of low temperature valves. The meeting was a complete success.
