China's valve industry before 1998 industry-wide number of enterprises in 1308, Guangzhou Kaiheng Valve Co., Ltd., of which 11 joint ventures, research centers all a research institute a class: Hefei General Machinery Research; Institute for a second category: Shenyang Valve Research; Institute of factories, 12. Industry-wide number of employees 18.5 million, of which the number of engineering technology 9200 people; 10 billion total industrial output value, industrial added value of 3.2 billion, with fixed assets of 6.22 billion, Shanghai and Shanghai Valve Manufacturing Co., net 4.05 billion on sales of 9.11 billion , Shanghai Guanlong Valve Machinery Co., Ltd., total profits and taxes 740 million, of which a total profit of 230 million; overall labor productivity of 17,297 yuan / person; the main export delivery value of 150 million. The original system Valve Society of Mechanical Department of the number of 139 member companies, including joint ventures 5, the number of research institutes 7, valves, number of employees 85,000 people, including 5,500 engineers and technicians. 98 According to the 1998 Association of factory statistics, the industrial output value of 3.06 billion, industrial added value of 970 million, fixed assets of 3.17 billion, net 2.09 billion on sales of 2.87 billion, profits and taxes 150 million, of which a total profit of 19.58 million; labor productivity 15,186 yuan / person, the main product output 119,000 tons. Imports of low-temperature valve four technical requirements of the importing cryogenic valves, refers to the use of low temperature steel as body material, control valve stem extensions for low temperature liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, temperature is -40 ℃ ~ -196 ℃ of the valve. Granville Shield VTON use a variety of US imports of cryogenic valves according to the requirements of different roles. 1, the valve switching action for cryogenic liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum media, mainly choose to import low temperature cut-off valve, cryogenic valve. 2, the valve for regulating the low pressure liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum medium, temperature, flow, imported cryogenic valve. 3, to prevent cold liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum choose to import the media back cryogenic valve. 4, used to secure cryogenic liquid storage and transportation equipment, when the pressure reaches a certain value safe discharge, to use low import safety valve.
