High pressure valve technology has become the bottleneck of China's valve market

the focus of the operation of the accessories of our tensile testing machine is to find a way to obtain a large polishing rate as soon as possible. In the current valve market in France, in addition to the low-pressure valves reaching the level acceptable to the international market, high-pressure valves still need to rely on imports. Under the situation that the macro economy continues to be optimistic, the production and sales indicators of most enterprises in the valve industry have maintained rapid growth, but affected by the price war, the industry's sales revenue and profit have decreased significantly compared with the same period last year. With the recovery of the world economy, the import and export of China's valve products have also increased. However, due to the large gap between China and foreign manufacturers in high-end technology, product technology will become a bottleneck restricting the development of China's valve products for a period of time in the future

valves are indispensable fluid control equipment for petroleum, chemical industry, power stations, long-distance pipelines, shipbuilding, nuclear industry, all kinds of low-temperature engineering, aerospace, marine oil extraction and other departments of the national economy. 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 90 have an annual output value of more than 5million yuan. Considering that polyurethane is liquid, 0

from the perspective of products, China's valve industry has been able to produce more than a dozen categories of products, such as gate valves, globe valves, ball valves, butterfly valves, safety valves, check valves, throttle valves, plug valves, pressure reducing valves, diaphragm valves, steam traps, emergency shut-off valves, 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 as high as 50 billion yuan, of which more than 10 billion yuan of the market is occupied by foreign valve enterprises

at present, there are still some problems in China's valve industry. For example, China's valve enterprises are mainly low-level, small-scale, family workshop enterprises. In terms of products, due to repeated investment and insufficient technology introduction, the leading products of China's valve enterprises are still low-quality. 2. Classified mass products of material testing machines. At present, all kinds of 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, and some valves required for high temperature and high pressure and key devices still rely on imports. In addition, there is a big gap between China's valve industry and foreign enterprises in the industrial structure, the industrial chain of the valve industry, and the degree of specialization of the industry

the reason for the low quality of domestic valve products is that due to the rapid expansion of the market, the original state-owned valve enterprises have closed down and switched to avoid late quality defects. Although a number of township enterprises have developed rapidly, due to the low starting point of township enterprises, very weak technical force and simple equipment, most of the products are produced by imitation, especially the low-pressure valves for water supply and drainage

however, the above problems do not affect the broad prospects of China's valve industry in the future. This is mainly due to the support of national policies and the strong demand of the valve product market, especially the commencement of several century projects such as' West to East Gas Transmission ',' West to East power transmission 'and' South to North Water Diversion 'requires a large number of valve products. In addition, China is facing the arrival of the era of industrialization, petrochemical industry, power industry, metallurgical industry, chemical industry, urban construction and other large users of valves will increase the demand for valve products. For example, during the "Eleventh Five Year Plan" period of the power industry, the total forecast of valves required for large and medium-sized projects of coal-fired power units is: the total demand for valves is 153000 tons, with an average annual demand of 30600 tons; The total demand for valves is 3.96 billion yuan, with an average annual demand of 792 million yuan. In addition, China is gradually becoming the largest processing plant in the world, and the processing and manufacturing of valve products are facing greater development space

it can be seen that as long as enterprises can seize opportunities, strengthen R & D capabilities, and constantly improve the scientific and technological content and product quality of products, they can occupy an active position in the fierce market competition
