In the face of a billion-dollar import market, our valve industry needs to develop high-tech products.

According to analysis by industry insiders, there is still a small gap between domestically manufactured valve products and imported products. The main manifestations are leakage, internal leakage, poor design, short life, inflexible operation, and the lack of valve electric devices and pneumatic devices. Reliable and other shortcomings, some products are only equivalent to the international level in the early 1980s. China currently has more than 100 billion yuan of valve market per year occupied by foreign valve companies. Therefore, during the “Eleventh Five-Year Plan†period, as an important part of major technical equipment, China’s valve industry will be on the one hand in petrochemical, power, environmental protection and urban construction. Other fields have achieved rapid development; at the same time, it is urgent to develop new products with high technological content and excellent performance.
Valves for petrochemical installations have attracted much attention in the industry. For example, the pipeline valves used in oil refining equipment account for 3% to 5% of the total investment of the equipment, among which the gate valves account for about 80% of the total number of valves; the acrylonitrile devices generally require the valves produced by API standards, among which the gate valves account for 75 of the total number of valves. About 50% of domestic ammonia synthesis devices currently use globe valves, which account for 53.4% ​​of total devices, 25.1% of gate valves, 7.7% of steam traps, 2.4% of safety valves, 11.4% of regulators and other valves, and valves of ethylene plants. A wide variety of gate valves are the most demanding. In addition, large-scale ethylene and low-density polyethylene devices also need ultra-high temperature, low temperature and ultra-high pressure valve products. With the development of offshore oil and gas exploration, the number of valves required for offshore platforms will gradually increase; urban gas accounts for 22% of the entire natural gas market, and the amount of valves used is large and varied; valves for long-distance pipelines for crude oil, refined oil and natural gas, and environmental protection The number of valves for the drainage system is also quite large.
With the development of a series of new petrochemical plants in the direction of large-scale, high-parameter, high-performance automation and complete sets, the development of the valve industry supporting them has been promoted. The number of valve products has continuously increased, and many new products have appeared. Such as high temperature, high pressure, forged pilot valve, metal seal, oil seal AVDCO valve, all welded full-diameter pipeline ball valve, lift rod ball valve, large diameter emergency cut butterfly valve, all-buried ball valve, high performance butterfly valve, pilot Safety valves, control valves, soft-seal plug valves for finished oils, gate valves and ball valves for deep-sea oil fields (under 3000 m seabed), high-pressure and large-caliber top-mounted ball valves, slurry valves for alumina high-pressure melting, and natural gas control Devices and so on.
According to statistics of foreign industrial countries, the output value of the valve is the sum of compressor, fan and pump, accounting for 5% of the total output value of the entire machinery industry. Currently, there are more than 6,000 valve manufacturing enterprises in China, and can provide more than 3,500 varieties and more than 40,000 specifications of valve products. The annual turnover of the valve market is as high as 50 billion yuan. About 900 of China's valve companies have an annual output value of more than 5 million yuan, of which China Nuclear Technology, Hongcheng, and Guangdong Pearl accounted for over 100 million yuan in revenue from their main operations last year. However, these companies are unable to achieve the same scale and quality of products. Compete with similar foreign companies.
Therefore, China's valve industry must achieve rapid development. Experts suggest that: First, the domestic valve industry should increase the research and development of new products, set up a new product research and development center, and focus on the development of new products for valves that are urgently needed in the domestic market and are technologically advanced. To achieve a full replacement of imports. In addition, we must also carry out forward-looking research and development to make technical reserves in the application of new materials and design of new sealing structures. Secondly, the valve industry should vigorously adopt international standards and foreign advanced standards and strictly implement the existing national standards so that valve products can reach the international level of the 1990s as soon as possible. At the same time, the technical transformation of the raw material selection, casting process, forging process, and heat treatment of castings and forgings should be carried out so that the blanks of castings and forgings can reach the international level in performance quality and appearance design. Third, it should continue to carry out internal and external leakage technology research, optimize the machining process, promote new types of sealing materials, improve the accuracy of key parts of the product processing, extend product life, so that the valve "a short two leakage" phenomenon has fundamentally improved.
The valve industry has a broad market space. China's valve companies can only expand their domestic and foreign markets in order to increase their research and development efforts, accelerate product structure adjustments, and upgrade their technology and upgrade their core competitiveness, in accordance with the goals of energy conservation, environmental protection, and safety.
