Qingdao Zhiyuan Valve Manufacturing Co., Ltd.

　　With the development of large sets of foreign technology, a series of new sets of equipment and stand-alone. With the characteristics of the valve on the development of new equipment is large, high parameterization, high-performance automation and complete sets of, complete sets of equipment with the control mode to adapt. For the past 20 years, the control mode of foreign valves has greatly developed.. In addition to the manual, mechanical, electric, gas, hydraulic transmission, the electric hydraulic linkage, gas-liquid linkage, automatic control valves varieties growing, and the trend of further development. Below Qingdao air pipe head of the small series to introduce you.

　　Such as oil refining equipment. The largest oil refinery 36400000 tons / year (the Caribbean Virgin Islands), 30000000 tons / year (Venezuela). At present, there are nearly 30 20 million tons / years of refinery; unit refining and vacuum distillation unit processing capacity to reach 24 million tons / year, the catalytic cracking unit to 824 million tons / year, the hydrocracking unit reached 320 million tons / year. Large scale device, forcing the valve is also growing, the control mode is also beginning to develop automation direction.

　　In recent years, long-distance pipeline development quickly, the main reason is low cost, only the equivalent of rail transport 1 / 3; second is buried in the ground, not easy to damage; the third is pipeline construction speed, low investment. Therefore, the valve in the valve for a long distance increased by the valve in recent years. The maximum capacity of the generator sets the capacity of the two axis fire motor group L30 million kW, the single shaft thermal power unit 1200000 kW, the maximum nuclear power unit 1300000 kW.

　　And the valve of the equipment supporting the largest plate gate valve diameter of 1620mm, 2000mm; maximum valve diameter 9750mm; maximum ball diameter 3050mm, the weight of the valve not drive to 184 tons; the maximum water valve through diameter 2750mm, the pressure to achieve 9Mpa.

　　The economic effect of large-scale equipment is summarized, one is to improve production efficiency, two is to reduce infrastructure investment, three is to reduce the consumption of raw materials. To deal with the capacity of 5000000 tons of oil refining equipment with 1000000 tons, compared to the annual investment of product production capacity of 50%. A 6 million tons / year refinery and two 300 million tons / year refinery, the investment is only a 69% of the latter, steel consumption was 53%, covers an area of 54%, production cost is 75%, and labor productivity has increased to 170%.
