Electromagnetic valve manufacturing level of construction engineering education needs to keep up with the needs of the development of the situation time finishing second division data, more secondary constructor examination counseling review guide information, please visit the construction engineering education network associate constructor column solenoid valve industry should set up enterprise groups, increasing investment in science and technology, development of high and large, refined, sharp valve products. Strengthen product standardization, make standard on the number and level of keep up with the needs of the development of the situation. In addition, the valve industry for many years in the application of tungsten cobalt chromium plasma wire automatic welding technology should inherit the promotion to replace manual welding, ensure the quality of the valve sealing surface; Automatic control device for project implementation process, should strengthen the development of the intelligent electric and hydraulic actuator valves; To speed up the development of new methods such as magnetic transmission, transmission develop new closed magnetic force drive valve series, eliminate funnelled between stem and packing, to make it applicable to flammable, explosive, toxic, corrosive medium and request a line lock, to avoid the mistake. Now understands from China general machinery industry association valve branch, in future years, thermal power, nuclear power, hydropower, large petrochemical, oil, natural gas gathering pipeline, coal liquefaction and metallurgical construction of major projects such as new product of form a complete set of valve, will become the development emphasis, is expected to lead the rapid growth of the whole valve market. Also after the 'west-east gas, and construction in China more than kilometers multinational gas transmission pipeline and feeder. Expert introduction, according to the association in the development of the electromagnetic valve product, should face up to the popularization and application of new process technology, such as the overall development of large diameter long distance pipeline ball valve overall welding technology should be adopted; For progress of valve sealing surface corrosion and erosion resistance, and a few manufacturers have begun to use supersonic flame spraying tungsten carbide process, at the same time should work with nanoscale materials of sealing surface coating modification, and the development of the laser cladding process technology. According to introducing, in future years, China will have thousands of kilometers of pipeline to construction, including Russia, kazakhstan and other multinational oil pipeline. The project is about more than just large diameter pipeline ball valve and small caliber valve, flat valve; ~ a thousands of large-scale refineries will construction, construction and reconstruction of a large group of m ~ - ethylene plant, has ~ ten thousand tons/year of batch and pending large also has more than ten sets of PTA plant, which will provide a huge market for the valve industry. Large fertilizer and the construction of the ammonia plant of the same will provide opportunities for the valve manufacturing; Other coal direct liquefaction is likely to form a new industry, because of the high coal direct liquefaction process medium temperature, high pressure, high solids content, has high demands to the solenoid valve, will form a new market.
