It is understood that in the next 10 years, new valve products supporting the construction of major projects such as thermal power, nuclear power, hydropower, large-scale petrochemical, petroleum and natural gas gathering and transmission pipelines, coal liquefaction and metallurgy will become the focus of development, which is expected to lead the rapid growth of the entire valve market. Therefore, the valve industry should establish enterprise groups, increase investment in science and technology, and develop high, large, precise and sharp valve products; We will strengthen product standardization so that standards can keep pace with the development of the situation in terms of quantity and level.
According to experts from the Association, when developing new products of these valves, attention should be paid to the promotion and application of new technology. For example, the development of large diameter integral ball valves for long-distance pipelines should adopt integral welding technology; In order to improve the corrosion resistance and erosion resistance of the valve sealing surface, a few manufacturers have begun to use the supersonic flame spraying tungsten carbide process. At the same time, attention should be paid to the coating modification of the sealing surface with nano materials and the development of laser cladding technology.
In addition, the cobalt chromium tungsten plasma wire feeding automatic surfacing process applied in the valve industry for many years should continue to be promoted to replace manual welding to ensure the quality of the valve sealing surface; In order to realize the automatic control of the process flow of engineering devices, the development of intelligent electric and hydraulic actuator valves should be strengthened; Accelerate the development of new transmission methods such as magnetic transmission, develop new closed magnetic transmission valve series, eliminate the leakage between valve stem and packing, and make it suitable for flammable, explosive, toxic and corrosive media and pipelines requiring locking and avoiding misoperation
