Technological bottleneck to be broken through and innovation to become the main melody of the valve industry

"in the fierce market competition, who has good technology, who has excellent product quality, who can continuously develop new products, who can win the first opportunity in the competition." Yejixuan, President of Zhejiang Yongjia pump and Valve Association, said at the fifth second general meeting of the valve branch of China General Machinery Industry Association held in Hangzhou on May 21

the overall level of the industry needs to be improved.

valves are indispensable fluid control equipment for various departments of the national economy, such as petroleum, chemical industry, power stations, long-distance pipelines, shipbuilding, nuclear industry, various low-temperature projects, aerospace and offshore oil production. After more than 20 years of development, there are more than 6000 valve enterprises of various sizes in China, and the number of enterprises ranks first in the world, of which 900 have an annual output value of more than 5million yuan

from the product situation, China's valve industry has been able to produce more than a dozen categories of products, such as gate valve, stop valve, ball valve, butterfly valve, safety valve, check valve, throttle valve, plug valve, pressure reducing valve, diaphragm valve, steam trap, emergency shut-off valve, etc., with the maximum service temperature of 570 ℃, the minimum of -196 ℃, the maximum pressure of 600MPa, and the maximum diameter of 5350 mm

in addition, according to the statistics of relevant departments, the annual turnover of China's valve market is up to about 50billion yuan, of which more than 10billion yuan is occupied by foreign valve enterprises. Although China's valve industry has made great progress through reform and opening up, there are still some problems: due to low-level repeated construction, the leading products of valve enterprises are still low-end mass products

in addition, at present, various valves produced by Chinese enterprises generally have shortcomings such as external leakage, internal leakage, low appearance quality, short service life, inflexible operation, and unreliable valve electric and pneumatic devices. Some products are only equivalent to the international level in the early 1980s. However, some high-temperature and high-pressure valves and valves required on key devices still rely on imports. In addition, it has become a new engine for the transformation of the city. Compared with foreign countries, China's valve industry has a large gap in the industrial structure, the industrial chain of the valve industry, and the degree of specialization of the industry

according to the analysis of experts in the industry, the main reason for the low quality of domestic valve products is that after the rapid expansion of the market, the original state-owned valve enterprises have been shut down one after another, and private enterprises have developed rapidly. However, private enterprises have a low starting point, very weak technical force, simple equipment, and most of their products are produced by imitation, especially the low-pressure valves for water supply and drainage, which have more serious problems

technological innovation drives product development

so how to break through this bottleneck and accelerate the development of the valve industry? Songyinli, Secretary General of the valve branch of China General Machinery Industry Association, believes that according to the changes in the valve market and the national development projects and relevant policies in the future, the technology and product development of valve enterprises in the future should focus on the following aspects:

in terms of product development, it is necessary to focus on large-scale projects, one is to develop complete sets of engineering valves, and the other is to focus on the production of multiple varieties and specifications of products. According to the current national key project development plan, which also determines the structure of the pulling machine, the demand of the valve industry during the "Eleventh Five Year Plan" period and the next few years is mainly in the fields of long-distance pipeline valves, "South-to-North Water Transfer Project", etc. Only for long-distance pipeline valves, it is estimated that 20000 kilometers of gas transmission pipelines will be built during the "Eleventh Five Year Plan" and in the next few years, so there is a great demand for large-scale pipeline ball valves. During the "Eleventh Five Year Plan" period, it is estimated that 5000 kilometers of high-pressure crude oil pipelines will be built, and more than 3000 high-pressure large-diameter valves will be required. The "South-to-North Water Transfer" project is a cross century project in China. The total investment of the East, central and West lines needs to exceed 450billion yuan. Among them, the east line water transfer project requires a large number of large-diameter gate valves, special square gate valves, special butterfly valves and supporting valves of the water pump station

in terms of technological innovation, we should pay attention to the adjustment of product structure, and it is crucial to research and develop products with high added value and international leading level. The failure of all domestic valve enterprises in the bidding for the main pipeline of West to east gas transmission is a painful lesson

learn from the bitter experience. To revitalize the valve industry, we must develop valve products with high technology content, high added value and international leading level

there are several ways for enterprises to carry out technological innovation and research and develop new products: first, they can cooperate with scientific research institutions of colleges and universities. For example, the main steam control valve of power plant boiler recently developed by Kaifeng high pressure valve factory and the "three dimensional" company subordinate to the Chinese Academy of Sciences is an internationally leading product. Its "pressure drop" is much lower than the international standard, which has a very broad prospect in the power plant industry; Second, in the form of cooperation with foreign countries or technology introduction, the cooperation between Zigong High Pressure Valve Co., Ltd. and Italy simbillon company has shortened the gap between us and foreign countries in ball valve products. Of course, enterprises with high precision conditions can also develop independently

in terms of market development, diversified sales strategies should be implemented, and necessary protective measures should be taken to open up the international market. To open up the international market, we should first pay attention to the cultivation of foreign trade talents; Secondly, we should learn to use Internet and information technology to capture business opportunities; Third, we can cooperate with some domestic foreign trade companies to expand exports through their channels; Fourth, qualified enterprises can set up sales outlets or set up factories abroad

industry experts believe that the most effective way to change the current situation of low-level repeated construction among industries as soon as possible is to realize the capital expansion of enterprises through the combination, merger and reorganization among enterprises, so as to further expand the market share, so as to remain invincible in the competition. This is a popular practice in the international economic field today, and it is also a directional issue for the development of the valve industry in the coming period. As long as there is the possibility of alliance among enterprises, they can boldly try to break the regional boundary, the ownership boundary and the traditional professional division of labor, and strive to create a number of enterprise groups with an output value of more than 500million yuan or even 1billion yuan in a short time
