First, the status quo of the valve industry
During the “10·5†period, the valve industry developed a key core equipment for the petrochemical large-scale adsorption molecular device – 24-way rotary valve; it is a key supporting equipment in petrochemical, food and pharmaceutical pneumatic conveying systems – solid material strength The valve for transportation (rotary feeder, conveying reversing valve, slide valve), and the production capacity, has achieved good results in the country, and developed a new generation of high performance single bidirectional for power generation, metallurgy, chemical water supply and drainage. Sealed three-eccentric composite ring metal sealing butterfly valve with a nominal diameter of 2000mm.
1200 °C high temperature butterfly valve used as control valve for sulfuric acid, pyrite-based acid, flue gas acid and colored smelting, black smelting, petrochemical, electric power system, blast furnace air distribution, boiler outlet and other high temperature pipelines; For the development of the nuclear industry, the development of the top-loading nuclear power ball valve, soft and hard seal high vacuum electromagnetic and manual pressure valve for nuclear fuel extraction; for the long-distance pipeline development and production of GK-type pipeline ball valve.
In order to improve the service life of the valve, it is suitable for the gate valve, ball valve and regulating valve of the wear-resistant ceramic sealing ring of the power station. In addition, it has developed and produced high temperature and high pressure Y-type bellows shut-off valves, low-temperature bellows chlorine valves, subcritical and supercritical high-temperature high-pressure shut-off valves, biological antibacterial diaphragm valves, etc. These new products fill the gap in domestic valve products.
In the market, after years of development, the valve industry manufacturers have increased rapidly, the valve production level has been greatly improved, and the valve output has increased significantly. The main products of the valve can basically meet the needs of the domestic market, and the complete set rate, complete set level and complete set capacity of the valve market are greatly improved.
At present, the valve industry can provide supporting valves for large-scale domestic complete sets of equipment, which have basically met 450,000 tons of synthetic ammonia, 520,000 tons of urea, 5 million tons of refineries, 60,000 tons of high pressure polyethylene, 450,000 tons of ethylene, 1.2 million tons of alumina. And large-scale projects such as 600,000 kW generator sets, and special valves for the nuclear industry and other defense industries.
Second, the "11th Five-Year" demand forecast
(1) Electricity market forecast During the “11th Five-Year Plan†period, the total valve demand for coal-fired power plant large and medium-sized start-up projects and coal power station maintenance projects is: the total valve demand is 153,000 tons, and the average annual demand is 3.06. The total demand for valves is 3.96 billion yuan, and the average annual demand is 792 million yuan.
During the “11th Five-Year Plan†period, the demand for valves of nuclear power plants will be 3 billion yuan, and the average annual demand will be about 600 million yuan. In addition, the maintenance cost of nuclear power plants spent on valves should account for more than 50% of the total maintenance.
(2) The high-temperature valve for ethylene cracking gas in the petrochemical industry is an essential valve for the 800,000 t ethylene plant cracking furnace outlet pipeline. It is necessary to develop a cracking gas valve as soon as possible. Large-diameter high-pressure ball valves, large-diameter oil pipeline ball valves, and cryogenic valves for liquefied natural gas have a large demand.
(3) Key equipment for large-scale coal liquefaction project The coal liquefaction plant involves a large number of special valve products with high requirements. To ensure the national energy security, the start-up and construction of the coal liquefaction project is undoubtedly an urgent matter. High temperature and high pressure wear resistant valves to meet the needs of coal liquefaction development.
(4) Metallurgical equipment required for metallurgical equipment: blast furnace bellless top equipment, gas special valve, hot air valve, gas shut-off valve, oxygen valve, hot blast stove complete valve, gas TRT complete valve, blind plate valve, flapper valve Butterfly valve (wear resistant), ball valve (wear resistant), etc.
(5) The “South-to-North Water Transfer†project “South-to-North Water Transfer†requires a large number of large-diameter gate valves, special square gate valves, special butterfly valves and pumping station supporting valves.
(6) Environmental protection engineering urban sewage treatment equipment, gas desulfurization equipment, harmless urban garbage, resource equipment and other valves will be hot spots for domestic supply and demand in the future.
Third, development goals and development priorities
(1) Development target It is predicted that by 2010, the total demand for domestic valves will be 34.5 billion yuan.
(2) Development focus According to the needs of China's national economic development, we should focus on supporting the development of new valve products for major projects such as thermal power, nuclear power, hydropower, large petrochemicals, oil and gas gathering and transportation pipelines, coal liquefaction and metallurgy.
In the development of the above new products, we should pay attention to the promotion and application of new process technologies, such as the application of vacuum electron beam welding new technology and shear extrusion technology when developing high temperature and high pressure power stations and nuclear power plant valves using forged welded structures; Ball valves use integral welding technology.
