Valve technology to be a breakthrough bottleneck
"In the fierce market competition, who have good technology, who have excellent product quality, who can continue to develop new products, who will be able to win the first chance in the competition." Zhejiang Yongjia Valve Association President Ye Jixuan May 21, held in Hangzhou, China General Machinery Industry Association Valve branch fifth session of the General Assembly said. The overall level of the industry to be improved Valve is an indispensable fluid control equipment for various sectors of the national economy such as petroleum, Chemical, power plants, long-distance pipeline, shipbuilding, nuclear industry, a variety of cryogenic engineering, aerospace and marine oil production. After more than 20 years of development, there are about 6,000 enterprises of all sizes and sizes in our country, and the number of enterprises ranks first in the world. Among them, there are 900 enterprises with an annual output value exceeding 5 million yuan. From the product situation, China's valve industry has been able to produce more than 10 major categories of products, such as gate valve, globe valve, ball valve, butterfly valve, safety valve, check valve, throttle valve, plug valve, pressure reducing valve, diaphragm valve, Traps, emergency shut-off valve, the highest temperature reached 570 ℃, the lowest -196 ℃, the maximum pressure of 600MPa, the largest diameter of 5350 mm. In addition, according to the relevant department statistics, China's annual turnover of the valve market up to 50 billion yuan, of which more than 100 billion market was occupied by foreign valve companies. Although China's valve industry has made great progress after the reform and opening up, but there are still some problems: Due to the low level of repeated construction, resulting in the leading valve products are still low-end mass-based products. In addition, at present, all kinds of valves produced by our country enterprises generally have the defects of leakage, internal leakage, poor appearance quality, short life, inflexible operation and unreliable valve electric devices and pneumatic devices. Some products are only equivalent to The early 1980s at the international level. Some high temperature and pressure and the key valve on the device is still dependent on imports. In addition, China's valve industry in the industrial structure, the valve industry chain, as well as the degree of specialization in the industry and so on, compared with foreign countries there is a big gap. Analysis of industry experts, resulting in the domestic valve product quality is mainly due to low: the rapid expansion of the market, the original State-owned valve enterprises have shut down and turn, the rapid development of private enterprises up. The low starting point of private enterprises, technical strength is very weak, poorly equipped, mostly imitation of products, especially for low pressure valves for drainage, the problems are more serious. Driven by technological innovation product development so how to break through this bottleneck to speed up the development of the valve industry? China General Machinery Industry Association Valve branch secretary-general Songyin Li believes that, according to changes in the valve market and the country's development projects and related policies for some time to come, the future of valve technology and product development should focus on the following aspects: In product development, To deal with large-scale projects, first, the development of complete sets of valves, and second, focus on product variety and multi-specification production. According to the current national key project development plan, the valve industry, "Eleventh Five-Year" period and the following several years of demand is mainly in the long-term pipeline valves, "South-North Water Diversion Project" and other fields. Only long-term pipeline valves, "Eleventh Five-Year" and the coming years is expected to build 20000 km of gas pipelines, large-scale pipeline ball valve has great demand. During the "Eleventh Five-year" period, it is estimated that a new high-pressure crude oil pipeline will be 5,000 kilometers long, which will require more than 3,000 high-pressure large-diameter valves. "South-to-North Water Diversion Project" is a cross-century project in our country. The total investment in the three eastern, central and western regions needs to exceed 450 billion yuan. Among them, the East Line Water Project requires a large number of large-caliber gate valve, special square gate valve, special butterfly valve and pump station supporting valve. In technological innovation, we must pay attention to the adjustment of product structure, and research and development of products with high added value and world-leading level are crucial. West-East Gas Pipeline bidding, all domestic enterprises failed to defeat is a painful lesson. Bitter experience, the valve industry to revitalize it must be developed to develop high technology, high added value, with the leading international level of the valve products. Implementation of technological innovation, research and development of new products, enterprises have a few ways to go: First, and institutions of scientific research institutions, such as the recent Kaifeng High Pressure Valve Factory and the Chinese Academy of Sciences under the "three-dimensional" company to develop the main boiler steam valve is With the leading international level of products, the "pressure drop" is much lower than the international standards, the power plant industry has a very broad prospects; the second is to cooperate with foreign countries or take the form of technology imports, Zigong High Pressure Valve Co., Ltd. and Italy Si Bililong The cooperation has shortened the difference between our ball valve products and foreign countries. Of course, qualified enterprises can also be independently developed. In the market development, should implement a diversified sales strategy, and strive to open up the international market. Thirdly, we can cooperate with some foreign trade companies in our country to expand their exports through their channels. Fourthly, qualified enterprises can set up factories in foreign countries Point of sale or start a factory. Industry experts believe that as soon as possible to change the status quo of low-level redundant construction industry, the most effective way is through joint, merger, reorganization of enterprises to achieve the expansion of capital of enterprises, thereby further expanding the market share, so as to be able to compete in the neutral Unbeaten. This is a more popular practice in today's international economy and is also a direction issue for the development of the valve industry in the coming period. As long as there is a united possibility between enterprises, they can boldly try to break the regional boundaries, break the boundaries of ownership and break the traditional professional division of labor. They will strive to create a number of enterprise groups with a production value of over 500 million yuan and even one billion yuan in a short period of time.
