Three fine valves to speed up the rapid development of enterprises to do what?

At present, the gap between China's valve industry and foreign valve industry is relatively obvious, let us see their own deficiencies, in order to find the gap and the essence of the problem, so as to improve and improve. There are four major comprehensive gaps that the author has learned from the field in the industry and the relevant analysis materials. The first is the gap in technological innovation capability; the second is the gap in processing technology; the third is quality management and equipment. The gap is the gap in process management; it can be analyzed from the following aspects.

1. The gap in technological innovation capacity The lack of technological innovation capability is a stumbling block to the development of our valve industry. At present, the design level of China's valve industry is not high. Although China's backbone enterprises have certain research and development conditions, the majority of valve companies' R&D centers are limited by personnel and facilities, lack adequate investment in capital, and have relatively closed research and development and technical service capabilities. According to the company's needs and only for corporate services, according to sales orders for the design, process preparation, the function is also relatively simple; such as the valve production process of on-site technical processing, or engaged in a small amount of new product development. Compared with developed countries, there is a big gap between domestic valve design standards.

At present, many domestic valve companies have rarely made innovations after introducing advanced technologies. When overseas customers visited China's heavy industry projects, such as papermaking, petrochemicals, etc., it was found that the valve products of many projects only changed on the basis of Western design prototypes. The processing technology is also relatively backward, although some domestic valve manufacturing companies have modern equipment that can achieve automatic operation, and even make some Western companies dwarf. However, most companies are outdated equipment and working environment. At present, China's valve companies can cast valve products such as steel, iron, aluminum, copper, and composite materials. However, due to backward casting methods, raw materials such as cast steel and cast iron are wasted in the production process, and environmental protection is also poor.

For example, most manufacturers in China cannot independently perform effective seismic analysis of valves. These manufacturers must entrust design institutes to carry out seismic analysis. Only some manufacturers have mastered the stress calculation and seismic analysis of valves, and fatigue analysis of valves. As well as impact analysis, this has, to some extent, constrained the increase in the level of research and development capabilities of domestic manufacturers. Domestic cooperation in production, education, and research is also relatively low, and the technical content of self-developed products is also relatively low. While some institutions of higher learning and research and design institutes have professional, departmental, and chamber-based research on valve technology, they are only valves for the entire device. The role and required characteristics of the proposed technical requirements, and does not start the development of valve product design and manufacturing technology, even if there are design drawings, often lack of technology, and practical operation does not meet, and some of the key due to the lack of practical verification tools, This is the main reason leading to the low overall technical level of domestic valve products.

Valve companies with higher technological standards in foreign countries usually have special R&D centers. In contrast, they have abundant funds, various related research institutions, and professional and technical engineering personnel to support them. These R&D centers are often equipped with There are specialized laboratories and testing organizations, and the computer application software applied to valve products is quite complete: theoretical analysis and prediction of advanced performance of new products and new technologies can be performed through analytical means, and experimental methods can also be used to predict results. The verification is performed, and the correctness of the analysis method is verified based on the statistical data, and a series of effective valve performance and technical characteristics analysis methods are obtained. Such methods are applied to the development of follow-up valve technology, and even lower the research and development costs. Its research results are more effective.

A lot of corporate valve products have obtained many national patents, but many patents are only practical patents, and their technical content is not high. Many patents have only been partially improved in structure, and have not substantially improved the invention. Some still have copying and plagiarism. Since many valve users have stayed in the use of traditional products for many years, many internal and external structures of products have not substantially improved and improved for many years.

Another example is the current China's valve actuator actuator control level is also poor. Domestic production of valve supporting actuators, its performance and control level is only foreign in the 1990s level, its poor sensitivity to the action, the overall level of automation control and reliability lags behind. With this, a series of control capabilities such as signal acquisition, signal comparison, signal amplification, and signal return lag behind those of developed countries.

In fact, in terms of technical level, the design of conventional valves and the application of materials, we do not have much difference compared with well-known foreign companies, and there is no insurmountable gap in the manufacturing process. What is the difference? However, the actual situation is that in the serious word, there is such a product, originally a patent valve of a company in Germany, there are several different companies at the same time production, one is a foreign company, one is a Taiwan-funded enterprise, one Is a domestic company. The same product map, the actual valve produced is different. The first two companies have better internal quality and appearance than domestic ones. What is puzzling is that these companies are producing such products in China, and the castings are made from domestic factories, but the results are quite different. In a sense, our business philosophy, the pursuit of goals and foreign-funded enterprises have a big gap, especially in the rough processing technology, there are indeed some problems, but also our reflection.

The practice of foreign companies is different from that of Chinese enterprises. The Chinese enterprises first engage in infrastructure construction, expand production plants and add production equipment. The plant also expands and expands, pursues large-scale and modern style, and only wants to expand the scale of production and ignores it. Due to the R&D and investment in new products, the product's stamina is seriously insufficient, and most of the production products are imitations, only ordinary low-grade products are produced, too much effort is put into market operations, and improper competition is used to engage in product marketing competition, thus lacking core competition. force. A lot of domestic companies engaged in research and development, the more is to refer to the design of other manufacturers, thus ignoring the importance of the original experimental data, so that the product developed only has a shape and no real soul.

As a whole industry system, there are also certain problems. Our R&D system is quite weak, but it is weak in innovation. Now, some companies have many branches and associates, and some companies invest in R&D capabilities and build scientific teams. At the same time, there are also small investments in the establishment of research and development facilities. In fact, the investment in R&D is very large. Currently, the R&D team, R&D methods, R&D product testing measures, and type testing equipment of the entire industry are insufficient to support our valve industry. The implementation of scientific research and development and development of new products, not to mention the development of high-end products.

At the same time, we must soberly realize that as China has entered the WTO for several years, China’s economy has gradually integrated itself with the world’s economy, and strong foreign-funded enterprises have taken over China’s valve market. These overseas legions have strong capital and high technology. Rich business strategy, invisible to the Chinese valve market constitute a certain **, but also our main competitors in the valve industry. At present, they are acquiring valve companies in China, attracting high-tech technical talents in the valve industry, using well-known brands, and seizing the high-end valve market in China. Some have invested in building factories in China, some have relocated their headquarters to China, and some have set up R&D centers in China.
