Domestic Valve Industry Lending on Market Science and Technology Continuation
The valve market competition is becoming more and more fierce. The current situation of the valve industry in China is that some ordinary valve products have saturated the market and the supply exceeds the demand. This makes the development of small and medium-sized enterprises more and more difficult. Even the products with high technology content compete very fiercely in the international market.
Since last year, the localization of high-end valves has been extremely bumpy. At present, the basic components have become the short board that restricts the development of manufacturing industry to high-end. Facing the challenge, the domestic valve industry is also developing towards the direction of high technology content, high parameters, strong corrosion resistance and long life with the continuous development of science and technology in the market. At present, China's valve market, has been able to provide heating valves, environmental protection valves, construction valves, etc., a variety of. But in the field of high-pressure valves still rely on imports, which is also the future of China's valves need to break through the field, in order to truly promote the development of China's valve industry.
During the 12th Five-Year Plan period, the government will continue to intensify the localization of high-end equipment components. Here we select several representative valves of key development industries mentioned in the Implementation Plan for feasibility analysis of import substitution (such as petroleum, power station, metallurgy, machinery, electronics, mining, chemical industry, building materials, electricity, energy, sewage treatment, etc.). From the analysis, we can see that the feasibility of valve import substitution varies greatly among sub-industries, and high-end valves need more policy guidance and scientific research support.
On the one hand, the external market is continually weak, on the other hand, the comparative advantage is weakened under the influence of rising comprehensive costs. The domestic valve equipment manufacturing industry is facing a "painful period" of industrial restructuring. Valves are products with low profit margin, and the market competition is very fierce. At present, China's valve industry is labor-intensive industry, China's valve industry is still dominated by volume expansion. Although more and more valve products originating in China are flowing in the international valve market, the voice of the international valve market is not in the hands of Chinese enterprises.
In order to have a long-term development, China's valve industry must adjust and optimize its industrial structure. It should not only continue to give full play to the advantages of traditional valve industry, but also vigorously develop knowledge-intensive and technology-intensive industries and emerging industries to promote the upgrading of pressure relief valve, cock valve and regulating valve industries. Only in this way can the gap between China's valve industry and developed countries be shortened as soon as possible.
Relevant personages in the industry said that in the industrial process, valves are mostly used to control the movement and flow of various fluids, such as water, oil, chemical liquids, etc., based on parameters such as temperature, pressure and flow rate. The control valves commonly used in factories are pressure reducing valves, pneumatic temperature control valves, solenoid valve temperature control system, proportional control valve temperature control system, temperature control valves and other types. When choosing all kinds of automatic valves, we should consider the types of heat engines, the required accuracy, the quality of control valves, pressure drop, flow rate and structure, failure rate, manufacturer's credit and after-sales service and other factors in order to achieve economic and practical purposes.
As far as the product itself is concerned, electric valves have the advantages of easy assembly, low failure rate and meeting the automation needs of the industry, which is a more cost-effective choice for the industry. Because the use of conventional pneumatic valves, it is inevitable to have piping, solenoid valves and compressors, and electric valves are driven by motors, easy to install and easy to install, and the installation of electric valves with the factory's original automatic control circuit can save other costs. In addition, the motor-driven mode of opening and closing is relatively smooth, without the shortcomings of excessive momentum, the failure rate can be greatly reduced.
In recent years, with the development of mechatronics, electric valve, an important mechanical product, has entered an unprecedented market. The huge market demand for electric valves has become increasingly demanding.
In terms of operation efficiency and energy saving, the use of automatic control valves is an indispensable part. The manual valves and pneumatic valves commonly used in traditional industry are inferior to electric valves in installation cost and efficiency. Some media say that electric valves have become the mainstream products in the valve market.
The market prospects of electric valves for refrigeration accessories in China are promising. After years of development, the number of valve enterprises in China ranks first in the world. There are more than 6000 valve enterprises of various sizes, of which 900 have an annual output value of more than 5 million yuan.
