China's valve industry valve industry with foreign gap is more obvious

The development of China's valve industry restriction factors, there are a lot of technical * * ability is insufficient. At present domestic water supply and drainage of low pressure valve is basically simple mechanical or electrical control, or even manual control, low level of intelligence. The change of the electric power industry, petrochemical industry, industrial policy, the control valve ( And regulating valves, including control valves, pneumatic control valve/pressure regulator, self-reliance self-reliance type control valve, electric ball valves/butterfly valves, pneumatic ball valve, butterfly valve, pneumatic Angle seat valve, electric brake valve/cut-off valve, pneumatic cut-off valve, gate valve, solenoid valve, etc. ) The influence of the market is enormous. Countries opening up after the big petrochemical group in China's investment abroad, many large group, such as basf, shell, such as increased investment in China, which stimulates the development of the control valve market. At present, China's valve industry valve industry with foreign gap is more obvious, also let us see one's own is not enough, to find the gap and the question, to improve and improve. Field know the author from the industry, as well as the relevant analysis data outlined in, there are four big comprehensive gap: one is the gap on technology * * ability; The second is processing technology gap; 3 it is the difference between quality management and equipment; Four is on the process management of gap; The concrete from the following several aspects to analyze. Technical * * ability is insufficient, it is a stumbling block to prevent us from the valve industry development. At present, China's valve industry design level is not high, although the domestic backbone enterprises has certain research and development conditions, whereas most of the research and development center by the valve business personnel, facilities, lack of enough capital investment, research and development and technical service ability is relatively closed, mainly according to the enterprise needed and only for the enterprise service, according to the sales order and design, process preparation, function is relatively simple; Such as the valve in the process of production on-site technical processing, or to engage in a small amount of new product development. Domestic valve design level compared with the developed countries, there is a big gap. The domestic many valve enterprise rarely again after the introduction of advanced technology for * *. When overseas clients to visit China's heavy industry projects, such as papermaking, petrochemical, etc. , found that many projects of valve products only in the west did change on the basis of the design of the prototype. Processing technology also is relatively backward, although some domestic valve manufacturing enterprises have modern equipment, can realize automatic operation, even make some western companies are in the shade. But most companies are obsolete equipment, poor working conditions. Enterprises at present, China valve can cast steel, iron, aluminum, copper, composite materials and other products, but as a result of casting process means backward, cast steel, cast iron and other raw materials in the production process of waste is very big, environmental protection is also poor. Most domestic manufacturers can not independently, for example, the valve and effective seismic analysis, and the manufacturer shall entrust the design seismic analysis, only the individual manufacturer is fully mastered the stress calculation and aseismatic analysis of valve, valve fatigue analysis, and the analysis of the impact, in the certain extent, restricted the domestic manufacturer to raising the level of research and development capabilities. Domestic production, cooperation degree is low, the independent development of products technology content is low, and some of the institutions of higher learning and research and design institute is equipped with professional, office, room in valve technology research, but it is only on the function of the device of the valve and the characteristics of the proposed technical requirements, do not open the valve product design and manufacturing technology research and development, even with the design drawings, often lack of manufacturability, some does not adapt with actual operation, some of the key because of a lack of actual verification method, which is lead to domestic valve products the main reason for the overall technical level is low.
