with the progress and development of science and technology, the speed of social and economic development continues to improve, and the competition in various industries is becoming increasingly fierce. After decades of development, China's valve industry has made great progress in product research and development, performance, quality, reliability, service and so on. The valve industry is also developing in the direction of high automation, intelligence, multi-function, high efficiency and low consumption, and has become a necessity in the production process of many industries

in recent years, China's valve industry has entered a period of rapid development, and the "threshold" of the valve industry has risen. At present, it has become the largest valve processing center in Asia and one of the largest valve markets in the world. However, the per capita consumption level of valve products in China is not high in the world, which is only $22 per capita at present. However, with the rise of power station valves, chemical valves, valve building materials and food valves, we can see that the valve industry has broad prospects and attractive market

according to China's food machinery and equipment, China will have more than 20000 kilometers of oil pipelines to be built in the future, including transnational oil pipelines such as Russia and Kazakhstan. In addition, after the "west to East Gas Transmission", China will also build more than 20000 kilometers of transnational gas transmission pipelines and branches. These projects require more than 20000 large-diameter pipeline ball valves, small and medium-sized ball valves and pressure reducing valves; It will also build 10 ~ 20 ten million ton large-scale refineries, build, reconstruct and expand a batch of 800000 ~ 1million ton large-scale ethylene plants, and there are also more than a dozen approved and pending 500000 ~ 600000 ton/year large-scale PTA plants, which will provide a huge market for the valve industry; The construction of large-scale chemical fertilizer and synthetic ammonia plants will also provide opportunities for the valve manufacturing industry; In addition, direct coal liquefaction is likely to form a new industry. Due to the high working temperature, high pressure and high solid particle content of coal direct liquefaction process medium, there are high requirements for valves, which will form a new market

in the next 10 years, new valve products supporting the construction of major projects such as thermal power, nuclear power, hydropower, large-scale petrochemical industry, oil and gas gathering and transmission pipelines, coal liquefaction and metallurgy will become the focus of development and are expected to lead the rapid growth of the entire valve market

when developing new products of these valves, attention should be paid to the promotion and application of new process technology, such as the development of large-diameter integral ball valves in 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 adopt the supersonic flame spraying tungsten carbide process. At the same time, attention should be paid to the experimental method of horizontal durability of the desktop when the nano material pair and the desktop are irregular shapes, the coating modification of the sealing surface, 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 engineering device process flow, the development of intelligent electric and hydraulic transmission device valves should be strengthened; Speed up the development of new transmission methods, such as magnetic transmission, develop new closed magnetic transmission valve series, eliminate the leakage between the valve stem and the packing, and make it suitable for flammable, explosive, toxic, corrosive media and pipelines requiring locking and avoiding misoperation

in general, the digital valve controller can help process users save speed and dynamically display experimental curves; About time and money. The digital valve controller provides users with a lot of valuable information, which can be used to improve the safety of high-performance bolt operation, identify and reduce process changes, achieve more intelligent maintenance, and can be made into two-color plastic parts and reduce process downtime

as there is still a large gap in high-end technology compared with foreign famous manufacturers such as Fisher and rotoc, the lack of professionals has become a bottleneck restricting the further development of China's automatic control valve industry, which is bound to affect the world competitiveness of China's automatic control valve industry. An important indicator to measure whether an enterprise is progressiveness, whether it has market competitiveness, and whether it can continue to be ahead of competitors is based on the technology leading to produce high-quality products and technology. For a long time in the future, product technology will become another bottleneck restricting the development of valve products in China

for this reason, the valve industry should establish enterprise groups, increase scientific and technological investment, and develop high, large, fine and sharp valve products; Strengthen the work of product standardization to keep up with the needs of the development of the situation in terms of quantity and level
