Les vannes industrielles sont une partie importante des équipements industriels. Les vannes industrielles font principalement référence aux dispositifs qui contrôlent le débit de fluide, pression, and flow direction by changing the size of their flow channel area.
They are control components in fluid conveying systems. Their functions include opening and closing, regulating, throttling, etc.. Industrial control valves are mid-to-high-end products among industrial valve products.
Control valves are control components in fluid conveying systems, with functions such as cutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion, or overflow pressure relief.
Industrial control valves are mainly used for process control in industrial equipment and belong to the instrumentation, metering, and automation industries. Control valves are similar to robot arms in the process of realizing industrial automation.
They are the final control elements for changing process parameters such as medium flow, pression, température, and liquid level. Because they are terminal actuators in industrial automation process control systems, control valves are also called “actionneurs” and are one of the core components of intelligent manufacturing.
Control valves are composed of two main assemblies: valve body assemblies and actuator assemblies (or actuator systems), which are divided into four major series: single-seat series control valves, double-seat series control valves, sleeve series control valves, and self-actuated series control valves.
Unlike manual valves, control valves are general fluid mechanical equipment and are industrial automation instruments that achieve automatic control and precise flow regulation under complex and harsh working conditions. Control valve technology involves related cross-disciplinary technologies such as material engineering, mechanical design and manufacturing, fluid mechanics, control science and engineering, measurement technology and instrumentation, and is widely used in industrial fields such as petroleum, gaz naturel, industrie chimique, métallurgie, pouvoir électrique, nuclear industry, aérospatial, military industry, construction navale, marine engineering, protection environnementale, et produits pharmaceutiques.
Development history of industrial control valve industry
The development of industrial control valves is closely related to the development of industrial production processes. Maintenant, in order to adapt to the special requirements of new industrial sectors or processes, modern industry has put forward higher requirements for control valves, such as more stable quality, safer operation, and stricter environmental protection standards. Some specific industries even put forward bubble-level requirements for the hard seal and emergency cut-off leakage rate of valves.
With the continuous advancement of science and technology, the market demand for product functions is increasing, the technical level of China’s control valve industry is constantly improving, and intelligent control valve products with automatic control technology are gradually emerging, continuously realizing the technical iteration from low-end products to mid-to-high-end products. As the world’s largest manufacturing country, China’s diversified industrial sectors such as oil and gas, produits chimiques, électricité, food and beverages all have a large demand for control valves. En outre, the Chinese government’s infrastructure investment and industrial modernization plans, comme le “new infrastructure”, have also provided further growth momentum for the control valve market.
China has made significant progress in science and technology, especially in automation, control systems and sensor technology. These technological advances have provided Chinese manufacturers with more opportunities and conditions to develop and produce industrial control valves with high performance. The demand for industrial control valves in the Chinese market continues to grow, especially with the renewal and replacement of some old equipment. Faced with huge market demand, Chinese companies have greater motivation and motivation to increase the localization rate.
With the continuous improvement of the innovation capabilities of Chinese companies, more and more Chinese companies have begun to conduct research and development and innovation in the field of industrial control valves. Innovation helps to improve product quality and performance and enhance the advantages of Chinese control valves in market competition.
Industry technical level and characteristics
The control valve industry is a typical technology-intensive industry and a high-tech industry in the traditional manufacturing industry. The technical characteristics of the control valve industry are: high technical content of products, relatively complex production processes, and a wide range of technologies. It integrates electronics, machinery, capteurs, matériaux, software, cybernetics, communications, physics, fluid dynamics, fluid simulation and other technical fields. It is an industry with a high concentration of new technologies in traditional manufacturing. The industry has high requirements for technological innovation capabilities, and the innovation and application of new materials and new processes are fast.
Technological innovation puts forward requirements for the management innovation capabilities of control valve industry enterprises. Management concepts such as MES advanced manufacturing system and CRM customer relationship management system have been introduced and applied in the industry. En même temps, with the continuous development of modern design technology, such as the widespread application of embedded design such as three-dimensional design and CAD/CAM system, the design efficiency of new products of enterprises has been greatly improved, and the product development cycle has been shortened.
Main downstream operation of the control valve industry
Control valves can be divided into two categories: gas control and liquid control according to the different control media, and can be further subdivided into several professional fields such as water control, refrigerant control, fuel control, air control, and gas control according to the media. Due to their professional characteristics, control valve products are of various types and have many applications.
Donc, the development of the terminal products they support directly affects the technical development trend and market development of control valves. The main application industries of control valves are petrochemicals, industrie légère, la production d'énergie, pétrole et gaz, and steel and metallurgy. With the upgrading of industrial control technology in recent years, the application scope of control valves has been continuously broadened, and the application development speed in papermaking, protection environnementale, nourriture, médicaments, and other fields has also gradually increased.
