The prospect of development of power station control pneumatic valve < / div >

China's electric power development in the national economic development has always occupied the first place, especially from 1987 to 1995 in this period of time, and last year was the biggest achievements of China's electric power development history, the fastest growing golden era. Power industry output value accounts for the proportion of the total industrial output value in 1987 from 3. 12% to 6%. Now new annual production capacity of more than 50000 mw power generation equipment, construction and the order of 300 ~ 600 mw unit greatly more than more than 80 sets. On the basis of 300 mw, 600 mw turbine, develop more powerful ( 1000 mw class) Supercritical pressure steam turbine unit of the project has been implemented. Toshiba has been put into operation 700 mw supercritical secondary middle reheat unit. In order to make the coal rich water poverty areas of rapid economic development, our country decided to focus on the development of 300 ~ 600 mw air cooling generating unit. In order to improve the thermoelectric efficiency, large 200 ~ 300 mw thermal power turbine are also being developed. Nuclear power industry is in rapid development. In several nuclear power station is introduced on the basis of the original level of 1000 mw nuclear power unit. So, large sets of development is the inevitable trend in our country electric power industry, which requires a large number of adoption of various kinds of pneumatic control valve, and from more than 100 mw, 300 mw unit in our country almost a lot and all adopt imported pneumatic control valve products, which raises many famous foreign pneumatic valves to China market. Predict the future 15 years of electric power development in our country, in the development of the future, with a focus on the development of supercritical 600 mw and larger capacity unit, improve and optimize the 300 ~ 600 mw subcritical unit, development of large thermal power units, the development of the steam Gas combined cycle and appropriate to speed up the nuclear power industry. In the long run, the development of nuclear power industry has a broad prospect, currently used in 300 mw nuclear power standard circuit, so that the development of 600 mw, 900 mw, 1200 mw. So in the next 15 years, China's domestic power generation equipment market demand quantity is quite big, is one of the most potential market in the world, entrepreneurs should have the vision aimed at the market. Adhere to is given priority to with domestic equipment, imported equipment is complementary is the principles of development of Chinese electric power industry. To this end, the Chinese government is formulating a series of policies in introducing foreign capital, including fair bidding with foreign firms. Under 300 mw unit, in principle no longer import, import of domestic production is not only large, more than 600 mw supercritical unit unit encourages chinese-foreign joint venture plant using domestic equipment and so on our country's policy to control the power station of home-made pneumatic valve is clearly support and favor. Look from the technical renovation of old unit power plant control pneumatic valve broad market. Our country of large unit has reached more than 591 units, the longest history for more than 20 years, all need technical reformation, many control pneumatic valve needs to be updated. Has a long history of manufacturing plants, as a result of the operation of old unit, task, as the main content of the current production task. A large number of power plants to run unit annual repairs, overhaul 2 ~ 3 years, need to change a certain amount of control in the maintenance of pneumatic valves and accessories, pneumatic control valve manufacturers should be sufficient enough to attach importance to the market. If each big unit according to the average 50 control pneumatic valve calculation, a total of pneumatic control valve as 50 * 591 = 29550, transform the repair rate is calculated at 10% a year, the need to control pneumatic valve replacement 2955 PCS per year, each control pneumatic valve average price is 80000 yuan, is 2955 * 80000 = 2. 3. 6 billion RMB, can see from the data control pneumatic valve in the repair of large market every year. Manufacturers should organize maintenance strength, to provide power plant a large number of products and accessories.
