    How to speed up the progress and development of the valve industry?

    Category:Industry News Publish:2013/1/8 15:55:10 Browse:1721 [Back]
    With China's rapid economic development, the valve industry as a national industry, after several years of trials, to the rapid development in all parts of the country, one of the major industries of the rapid development of the domestic machinery industry, the rapid pace of China's valve industry development, but more problems, the low level of development of the industry, low technological content of products, a lot of products, or low-end; due to the late start of the domestic valve industry is still in the development stage, the valve design, manufacture, production and testing capacity is lower than the foreign advanced level, a lot of key valve dependent on imports, many valve core technology, coupled with the restrictions on the level of automation and control, there is some discrepancy in the high-end valve technology developed with foreign, appear such issues What are the reasons? The following analysis and view only the personal views and ideas, can not help but correct, for reference only!
    Obvious gap between critical valve industry innovation and improvement

    Valve industry in China with foreign valve industry gap more obvious, and also allows us to see our own shortcomings, in order to find the gaps with the essence of the problem, thus improving and enhancing. I field from industry knowledge, and the general data about analysis, mainly four major gap: First, the technological innovation capability gap; gap on processing; Third, the quality of management and equipment gap; process management gap; concrete can be parsed from the following aspects.

    1, the gap on the technological innovation capability

    Lack of technological innovation, which is an obstacle to hinder the development of our valve industry. China's valve industry design standards are not high, the domestic backbone enterprises, although some conditions for research and development, while the majority of the valve business R & D centers by the limitations of the personnel, facilities, and lack of sufficient capital investment, research and development and technical service capabilities relatively closed primarily only based on business needs and corporate services, based on sales orders and design, process planning, simpler functions; such as on-site technical processing valve production process, or engage in a small amount of research and development of new products. The domestic valve design level, there is a big gap compared with developed countries.

    Many domestic valve enterprises to introduce advanced technology, very little innovation. When overseas customers to visit China's heavy industry projects, such as paper making, petrochemical, found many projects valve products just made a change in the Western prototype based on. Processing more backward, despite some domestic valve manufacturing companies have modern equipment, automatic operation can be achieved, even so some companies in the West are dwarfed. But most companies have outdated equipment and poor working conditions. At present, Chinese enterprises valve casting of steel, iron, aluminum, copper, composites of valve products, cast steel, cast iron and other raw materials in the production process, but because of the casting process backward means a great waste, environmental protection.

    For example: the majority of domestic manufacturers can not be independent seismic and other analysis of the valve, and these manufacturers to be commissioned to design institutions to conduct seismic analysis, only the individual manufacturers complete master valve stress calculation and seismic analysis, fatigue analysis of the valve, as well as impact analysis, which to some extent hampered the improvement of the level of R & D capabilities of domestic manufacturers. Also lower the degree of domestic research cooperation, self-development and lower technological content of products, although some institutions of higher learning and research and design institute with professional, at the room to carry out the study of the valve technology, but it is just the whole device valve the role of the properties required for the technical requirements, and does not expand on the the valves product design and manufacturing technology research and development, even if the design drawings, often lack the craft, and some are incompatible with the actual operation, some of which are critical due to the lack of effective means of authentication, This is the main reason for the overall low level of domestic valve products.

    Valve business is usually a higher level of foreign technology with specialized R & D Center In contrast, they have strong capital, excellent research institutions and professional technical engineering staff for support, and with these R & D centers are often needed predict the results of specialized laboratory and testing organizations, computer application software used in valve products is quite complete: either by analyzing the means of theoretical analysis and prediction of new products and new technology, advanced performance, but also can be used experimental methods validate, and to verify the correctness of the method of analysis based on statistical data, drawn from a range of effective valve performance and technical characteristics of the analytical methods, such methods applied to the the subsequent valve technology development, as well as in lower R & D costs, research more effective.

    Many enterprises valve products obtained many national patents, but a lot of patents only utility patents, technical content is not high, a lot of patent only in the structure of the paper improved, there is no substantive improvement invention. Some also exist imitation and plagiarism, because a lot of valves for many years remain in the traditional products, and thus a lot of products inside and outside the structure for many years no substantial improvement and enhancement.

    Another example is the current drive actuators to control the level of our valve products are also poor. Domestic production, supporting the valve actuator to its performance and the level of control only abroad 1990s levels, its action is poor sensitivity, automation and control capability and reliability of the overall level is lagging behind. Signal acquisition, signal comparison, signal amplification, signal return this series of ability to control the level of developed countries lagging behind.

    In fact, on the technical level, the conventional valve design and materials application, compared with the well-known foreign companies, and not much gap unbridgeable gap in the manufacturing process, and that the difference in where? But the actual situation is poor in earnest word, there is such a product, which was originally the valve of a German company patented product, there are several different companies at the same time production, one is a foreign company, a Taiwan-funded enterprises, a a domestic company. Same Figure, the the valve kind produced in different ways. The intrinsic quality of the former two companies appearance than domestic do. It is puzzling: several companies in China's domestic production of such products, and the rough castings from domestic factories, but the results are very different. In a sense, our business philosophy, the pursuit of goals and foreign-funded enterprises have a big gap, especially in the product on the rough machining process indeed there are certain problems, but also our reflection.

    Different practice of foreign enterprises and Chinese enterprises, Chinese enterprises first engage in infrastructure, the expansion of the production plant to add production equipment, the plant is also an expansion before expanding the pursuit of large, modern style, and just want to expansion of production scale, neglect R & D and investment in new products, product stamina is a serious shortage of production products are fabricated only to the production of ordinary low-end products, too much energy into the market operators, the use of improper means to engage in product marketing competition, and thus the lack of core competitiveness force. A lot of domestic enterprises engaged in R & D when more reference to the design of other vendors, thereby ignoring the importance of the original experimental data, only has the appearance of such products developed no real soul.

    As the entire industrial system, there are also some problems, our R & D system is quite weak, but weak innovation capability, some companies have a lot of plants and associates, some companies in R & D investment in capacity, the technology team building on, as well as the establishment of R & D means facilities investment is also small, In fact, R & D investment is great, the industry as a whole in the R & D team, R & D means research and development of detection measures, type test equipment, insufficient to support the valve industry implementation of science and technology R & D and development of new products, not to mention the development of high-end products.

    At the same time, we must clearly recognize that: With China's accession to the WTO for several years, China's economy gradually with the world economy, the strength of a strong foreign-funded enterprises in China have vied valve market offshore Legion has abundant capital and high-tech, there are rich business strategy, invisible, posing a threat to China's valve market, the main competitors of our valve industry. Acquisition of valve enterprises in China, high salaries to recruit the technical design of the valve industry talent, the use of a well-known brand, to seize the high-end valve market in China. Some invest and build factories in our country, some of the headquarters relocation, some set up R & D centers in China.
