The Development Of High

Two years ago, South Valve Independent research and development company

, and through hundreds of experiments 5 m large diameter vacuum butterfly came into operation, the first domestic Valve Into large-scale wind tunnel tests of national defense. For the test device to provide two-way vacuum seal valve and special valve, booster and "Change" Ben has made an important contribution to the month. In 2005 the company successfully developed the world's first zero-leak "-type metal seal butterfly valve regulating" alternative energy consumption, materials consumption and greater valve, globe valve, it successfully developed the closing time of 0.5 seconds is far below international standards The "fast close valve electro-hydraulic linkage," Localization of high-end valve.

Soviet nuclear valves and high pressure valves, Suzhou, China Lanzhou, high pressure valves for the nuclear chemical system provides a number of high-end localization of valves, including: nuclear Soviet Union in the 60-70 age of the original valve, independent research and development of the torpedo vacuum valves, vacuum valves rotor has as main products made of high-volume production, so that the relevant nuclear chemical system Key Valve vacuum valve-made torpedo technology. Shanghai Valve Factory in the past 40 years involved in major projects in many countries, such as the 1962 nuclear chemical enrichment projects to the state to provide stainless steel valves.

Recent localization of the key valve also yielded results: Paul Valve Group and Zhejiang University jointly developed the high-end ultra-low temperature valve, ultra-up valve for the Shenhua Group, Zhejiang assume "hydrogen from coal," Section of localization devices a number of research and development of high temperature resistant metal seal made of ball; Lanzhou High Pressure Valve Co., Ltd. Sinopec Puguang gas field for the independent research and development of anti-high-sulfur gas pressure plate gate valve made of a recent successful trial; Yangzhong City, Jiangsu Province Valve Factory R & D play a series of energy-saving environmental protection, special valves and other sulfur recovery unit, and applied more widely across the country to achieve these high-end localization of the valve. Beijing Aerospace Petrochemical Technology and Equipment Engineering Company developed "to meet the backup capacity of the safety valve discharge fast switching device" and "non-flow-type pilot relief valve to open conflict," two new localization.

Soviet nuclear valves, pressure valves, Lanzhou has become a large-scale ethylene megaton equipment and special valves made of the major suppliers of nuclear Su valve device company developed the hydrogenation of coke cleaning plate gate valve has been successfully Domestic chemical used in the East projects. Only in this field of nuclear Su valve special valve on supply nearly 100 million yuan to tackle problems specific technology research and development organization, so that large ethylene equipment made of special valve major breakthrough. Zhejiang, east China successfully developed the hydrogen valve valve valve and ethylene, through continuous effort to address the technical challenges, developed China's first hydrogen valve and the only new products such as ethylene valve, and into butterfly-free wear spherical only return valve, Chengdu Branch of China low-temperature test equipment, temperature test equipment; Staeger chemical development of "CO2 stripping urea special high-pressure regulator valve," the second in Zigong City, development and production of wear-resisting slagging pressure valve, Katz development and production of high temperature ball valve; River Power Smart Valve encryption security table before the valve, thus rewriting the country's historical dependence on imported valve hydrogenation. Hongseong valve successfully developed large diameter hydraulic turbine inlet valve, ring-jet flow control valve, 2.5 m 3 m turbine inlet valve and vacuum valve.
