Pneumatic control valve development present situation and restricting factors < / div >

the pneumatic control valve pneumatic valve industry in our country the development of the restriction factors, there are a lot of technical innovation ability is insufficient. At present domestic water supply and drainage of low pressure pneumatic 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 influence of the pneumatic valve to control the market is very huge. 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 pneumatic control valve market.
at present, the pneumatic control valve pneumatic valve pneumatic valve industry and foreign industry disparity is 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 the technology innovation 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.
technology innovation ability is insufficient, which is a stumbling block to prevent us from pneumatic valve industry development. At present, the pneumatic control valve of pneumatic 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 control pneumatic valve enterprise limited by 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 pneumatic control valve in the process of production on-site technical processing, or to engage in a small amount of new product development. Domestic control pneumatic valve design level compared with the developed countries, there is a big gap. At present, the domestic many control pneumatic valve companies rarely make again after the introduction of advanced technology innovation. When overseas clients to visit China's heavy industry projects, such as papermaking, petrochemical, etc. , and found a lot of project control pneumatic 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 control pneumatic 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. At present, China control pneumatic valve enterprise can cast steel, iron, aluminum, copper, composite materials such as pneumatic valve 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.
for example, most domestic manufacturers can not independently to analyze the seismic effective of pneumatic valves, the manufacturer shall entrust the design seismic analysis, only the individual manufacturer is fully mastered the stress calculation and aseismatic analysis of pneumatic valve, pneumatic valve fatigue analysis, and impact analysis, 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 to carry out the control of pneumatic valve technology research, but it is only on the function of the pneumatic valve in the device and the characteristics of the proposed technical requirements, not a pneumatic valve to control the 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 control pneumatic valve products the main reason for the overall technical level is low.
in Shanghai yellow cross industrial park, belongs to Shanghai pneumatic valve industry group; Has four production base, the factory covers an area of 82800 meters, the party a staff of 380 people, including senior technical staff 52: has a complete testing facilities, through the IS09001 international quality system certification, 2008, the national license for the manufacture of pressure pipeline safety TS certification, CE certification, API certification, Germany Rhine fire certification, etc. , effectively the quality of product is always in internal and external supervision and control, to ensure the quality of the company constantly updated management system, guarantee to maintain and improve the company's high standards will endure.
not only provide customers with reliable product performance, more focused on providing efficient, fast service, to this end, we set up the customer care center ( 4008 - 200 - 182).
