Why localization of high-end valves is difficult

"2012-2016 China's valve and cock manufacturing development prospects and investment forecast analysis report" shows that: from 2012, the road to localization of high-end valves has become very difficult. The current basic components have become a shortcoming that restricts the development of domestic manufacturing to high-end development. China's efforts to localize high-end equipment components need to be further increased.

Localization of high-end valves "difficulty in production" China's valve market (valve market analysis) has been able to provide a variety of products: such as heating valves, valves for environmental protection, construction valves and so on. Although in recent years through the efforts of domestic enterprises, some high-end pump products have been realized in the domestic, but there are still some products in the import state. According to the data provided by the China General Machinery Industry Association, the pump products imported by China this year include: hydraulic reciprocating piston pumps, other hydraulic reciprocating discharge pumps, and rotary axial piston pumps, with a rotational speed of 10,000 rpm. / Other centrifugal pumps, liquid pump parts, vacuum pumps, etc. Valve products mainly include: pressure reducing valve, hydraulic transmission valve, pneumatic transmission valve, safety valve or relief valve, valve parts and so on. In the field of high pressure valves still rely on imports, which is the future of China's valves need to make breakthroughs in the field. The industrial orientation of the high-end valve industrial park is to build a high-end, complete, international, and headquarters-based high-end valve city in China. It will introduce 200 high-end valve companies in 3-5 years, attract investment of over 20 billion yuan, and achieve an annual sales income of 500 yuan. Over 100 million yuan, the ultimate goal is to achieve an annual sales income of more than 100 billion yuan.

At present, whether it is in the domestic market policy support, or the current level of the existing technology, are not conducive to the development of high-end valves. In general, as the country's policy of accelerating the revitalization of the equipment manufacturing industry is gradually advanced, the development of the general basic manufacturing industry will receive further support. Large valve users in the petrochemical industry, power sector, metallurgy sector, chemical industry, and urban construction will increase their demand for valve products. However, the feasibility of valve import substitution in various sub-sectors in China varies greatly. High-end valves require more policy guidance. And research support.

Localization of high-end valves “What is it?” Difficult to produce According to the analysis of the person in charge of China General Machinery Industry Association, there are four main reasons for this phenomenon.

Long-term investment in R&D is insufficient. Domestic companies have a clear gap with some foreign developed companies in the concept of product technology development. The lack of investment in research funds and research and development funds has become an important factor restricting the independent research and development of valve companies. According to the incomplete statistics of the pump industry, R&D capital investment accounts for less than 2% of the company's main operating revenue. Compared with foreign well-known companies, R&D capital investment in the entire industry is low. Relevant statistics show that the annual research and development expenses of China's pump industry are not as good as that of a foreign company.

The ability of independent innovation is weak. It is understood that China's machinery manufacturing industry, the introduction of technology digestion and absorption is slow, most of the company's technological innovation capability is not strong, the main mechanical products, 57% of the core technology sources rely on the introduction. Although most of the products in China's water pump manufacturing industry have basically achieved independent production and manufacturing, domestic companies are mostly responsible for low-end processing of products, and the breadth and depth of autonomy need to be improved. For example, nuclear-grade pump products in domestically-produced nuclear power plant equipment and high-pressure boiler feed water pump core packages in million-kilowatt supercritical and ultra-supercritical thermal power plant equipment still require most of the key core technologies. Depends on imports.

Customers are less willing to purchase domestic products. Although domestic products have reached the same level as foreign countries in terms of performance indicators, some customers are still willing to purchase foreign technology equipment, making it more difficult for China's first pump with major technology (valve technology, pump technology) equipment to enter the market. Although many domestic high-end pump products have considerable technical levels, some use departments still refuse to use them due to lack of operating performance.

The lack of industry common technology research. Due to restructuring, some research institutes facing industry services have become companies that are fighting for each other. The nature of the structure and the focus of their work have changed greatly. The technical support of the industry is weakening day by day, the development of new technologies and new processes is slow, and it is difficult for the standards such as design, technology, materials and manufacturing to interface with foreign countries. In response, the person concerned put forward three suggestions:

First, establish a new mechanism to encourage independent innovation by enterprises. According to the comprehensive planning and regional layout planning of the national pump and valve manufacturing industry, a group of regional leading technologies and product development laboratories, test bases and product development centers will be established. Relying on scientific and educational institutions with strong innovation capabilities, establish a diffusion site for scientific and technological achievements. Encourage and support the establishment of a pump and valve manufacturing technology research and development center.

Second, improve the technology promotion system. Rationally set up grass-roots manufacturing technology promotion organizations, and gradually establish a diversified manufacturing technology promotion system that is led by the national manufacturing technology promotion organization, with division of labor and cooperation, and service in place.

In addition, we must improve the technology training system and improve the protection system for intellectual property rights. Establish and improve the connection between the training service functions of universities, research institutes, and secondary vocational schools and basic education, and give full play to the strength of institutions at all levels. Further improve the market environment for new product innovation and actively promote the development of new products. Enterprises and research institutes have established and improved rules and regulations for the management of new products developed independently.
