In China's current valve market, high pressure valves still need to rely on imports, except for low pressure valves that are acceptable to the international market. In the situation that the macro economy continues to be optimistic, most of the production and sales indicators of the valve industry have maintained rapid growth, but due to the price war, the industry's 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 valve products in China has also increased. However, due to the large gap in high-end technology compared with foreign manufacturers, product technology will become a constraint on the development of valve products in China in the future. bottleneck.

  From the product situation, China's valve industry has been able to produce more than a dozen major 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, Traps, emergency shut-off valves, etc., the maximum operating temperature is 570 ° C, **** is -196 ° C, **** pressure is 600 MPa, **** diameter is 5350 mm. In addition, according to the statistics of relevant departments, the annual turnover of the valve market in China is as high as 50 billion yuan, of which more than 10 billion yuan is occupied by foreign valve companies. The valves are petroleum, chemical, power station, long-distance pipeline, shipbuilding, nuclear industry, Various types of cryogenic engineering, aerospace and marine oil recovery and other indispensable fluid control equipment in various sectors of the national economy. After years of development, the number of valve enterprises in China ranks 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. At present, there are still some problems in China's valve industry. For example, China's valve enterprises mainly focus on low-level, small-scale, family-run enterprises. In the product, due to repeated investment, the introduction of technology is not enough, the leading products of China's valve enterprises are still low-quality mass products. At present, various valves produced by Chinese enterprises generally have shortcomings such as leakage, internal leakage, low 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 valves required for high temperature and high pressure and critical equipment are still dependent on imports. In addition, China's valve industry in the industrial structure, the industrial chain of the valve industry, and the degree of specialization of the industry have a large gap with foreign companies, resulting in low quality of domestic valve products: due to the rapid expansion of the market, the original state-owned valves Enterprises have shut down and turned. Although a number of township and village enterprises have developed rapidly, due to the low starting point of township and village enterprises, the technical strength is very weak, the equipment is simple, and most of the products are imitated, especially the low-pressure valves for water supply and drainage. The problem does 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 for the valve product market. In particular, the construction of several projects such as “West-East Gas Transmission”, “West-to-East Power Transmission” and “South-to-North Water Transfer” requires a large number of valve products. . In addition, China is facing the arrival of the industrialization era. 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 of the power industry, the total demand for valves for coal-fired power plants in large and medium-sized projects is: total valve demand is 153,000 tons, annual average demand is 30,600 tons; total valve demand is 3.96 billion yuan. The average annual demand is 792 million yuan. In addition, China is gradually becoming the processing factory in the world. The processing and production of valve products are facing more room for development. As long as enterprises can seize opportunities, strengthen research and development capabilities, and continuously improve the technological content and product quality of products. , can take the initiative in the fierce market competition.
