Valves are indispensable fluid control equipment in various sectors of the national economy such as petroleum, chemical industry, power stations, long-distance pipelines, shipbuilding, nuclear industry, various cryogenic engineering, aerospace, and marine oil extraction. After years of development, the number of valve companies in my country ranks first in the world, with more than 6,000 valve companies of various sizes, of which 900 have an annual output value of more than 5 million yuan. In my country's current valve market, in addition to low-pressure valves that have reached a 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, most companies in the valve industry have maintained rapid growth in production and sales indicators, but due to the impact of price wars, industry sales revenue and profits have fallen sharply compared with the same period last year. With the recovery of the world economy, the import and export of my country's valve products has also increased. However, due to the large gap between high-end technology and foreign manufacturers, product technology will become a constraint on the development of my country's valve products in the future. bottleneck. From the product situation, China’s valve industry has been able to produce more than a dozen categories of products, such as gate valves, globe valves, check valve
s, ball valves, safety valves, pressure reducing valves, needle valves, regulating valves, diaphragm valves, butterfly valves, Solenoid valve, trap, plunger valve, plug valve, forged steel valve, needle valve, instrument valve, level gauge, flow meter, exhaust valve, flame arrestor, knife gate valve, slurry valve, copper valve, balance Valves, stainless steel valves, fluorine-lined rubber valves, pipe clamp valves, American standard valves, power station valves, breathing valves, hydraulic control valves, vacuum valves, discharge valves, pneumatic angle seat valves, insulation valves, filters, bottom valves, For balance valves, drain valves, etc., the maximum operating temperature is 570℃, the minimum is -196℃, the maximum pressure is 600MPa, and the maximum diameter is 5350 mm. In addition, according to statistics from relevant departments, my country's annual valve market turnover is as high as 50 billion yuan, of which more than 10 billion yuan of the market is occupied by foreign valve companies. At present, there are still some problems in my country's valve industry. For example, my country's valve companies are mainly low-level, small-scale, family-based enterprises. In terms of products, due to repeated investment and insufficient technology introduction, the leading products of my country's valve companies are still low-quality mass products. At present, all kinds of valves produced by Chinese enterprises generally have shortcomings such as external leakage, internal leakage, poor appearance quality, short life, inflexible operation, and unreliable valve electric and pneumatic devices. Some products are only equivalent to the early 1980s. At the international level, some valves required for high temperature and high pressure and key installations still rely on imports. In addition, my country's valve industry has a large gap with foreign companies in terms of the industrial structure, the industrial chain of the valve industry, and the degree of industry specialization. The reason for the low quality of domestic valve products is: due to the rapid expansion of the market, the original state-owned valve enterprises have closed down and transferred. Although a group of township enterprises have developed rapidly, they have a low starting point, very weak technical force, poor equipment and products. Most of them are imitated production, especially the low pressure valve for water supply and drainage has serious problems. However, the above problems do not affect the broad prospects of my country's valve industry in the future. This is mainly due to the support of national policies and the strong demand in the valve product market, especially the start of several century projects such as 'West-East Gas Transmission. In addition, my country is facing the advent of the age of industrialization. The petrochemical industry, power industry, metallurgical industry, chemical industry and urban construction will increase the demand for valve products. For example, during the 'Eleventh Five-Year Plan' period in the electric power industry, the total valve forecast required for large and medium-sized coal-fired power generation projects is: total valve demand 153,000 tons, average annual demand 30,600 tons; total valve demand 3.96 billion yuan, The average annual demand is 792 million yuan. In addition, China is gradually becoming the world's largest processing plant, and the processing and production of valve products is facing greater room for development. It can be seen that as long as companies can seize opportunities, strengthen research and development capabilities, and continuously improve product technology content and product quality, they can occupy an active position in the fierce market competition.
