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 cryogenics, aerospace, and marine oil extraction. After years of development, the number of valve companies in China ranks first in the world. There are about 6,000 valve companies of all sizes, of which 900 have an annual output value of more than 5 million yuan.
From the product point of view, China's valve industry has now been able to produce more than 10 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 of 570 °C, the lowest -196 °C, the maximum pressure of 600Mpa, the maximum diameter of 5350 mm. In addition, according to relevant department statistics, China's annual valve market turnover as high as 50 billion yuan, of which more than 100 billion yuan of the market was occupied by foreign valve companies.
At present, China's valve industry still has some problems, such as the current China's valve companies mainly in low-level, small-scale, family-oriented enterprises. In terms of products, due to repeated investment and inadequate technology introduction, the leading products of China's valve companies are still low-quality mass products. At present, various types of valves produced by enterprises in China have the disadvantages of external leakage, internal leakage, low appearance quality, short life span, inflexible operation, and unreliable valve electric devices and pneumatic devices. Some products are only equivalent to the early 1980s. The international level. Some valves required for high temperature and high pressure and key equipment are still dependent on imports. In addition, China's valve industry in the industrial structure, the industrial chain of the valve industry, as well as the industry's degree of specialization have a large gap with foreign companies.
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 companies have been shut down and turned around. Although a number of township and village enterprises have developed rapidly, due to the low starting point of the township enterprises, the technical strength is very weak, and the equipment is simple. Most of them are imitating production, especially low pressure valves for water supply and drainage. The problem is serious.
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 for the valve product market. In particular, the start-up of several projects of the “West-East Gas Transmissionâ€, “West-to-East Electricity Transmission†and “South-to-North Water Transfer†projects require a large number of valve products; In addition, China is facing the arrival of the era of industrialization. The petrochemical industry, the power industry, the metallurgical industry, the chemical industry, and the construction of cities and other large-scale valve users will increase the demand for valve products. For example, in the electric power industry, during the “11th Five-Year Plan†period, the total valve demand forecast for large- and medium-sized projects in coal-fired power plants is: total demand for valves is 153,000 tons, average annual demand is 30,600 tons, and total valve demand is 3.96 billion yuan. The average annual demand is 792 million yuan. In addition, China is gradually becoming the largest processing plant in the world, and the processing and manufacturing of valve products face greater room for development.
This shows that as long as the company can seize the opportunity to strengthen its research and development capabilities and continuously improve the technological content of products and product quality, it will be able to take the initiative in the fierce market competition.

The heating effect of the air heater is not good. Where do you use it? Relatively speaking, the heating effect of the air heater is very good compared with other heating equipment. The air heater is also called industrial air heater, which has a wide range of applications,
Factory workshop: because the workshop space of many large factories is relatively large, it is basically impossible to use ordinary heating methods in such a large space, and it will also cause a lot of waste of infrastructure construction costs and later operation costs. At this time, you need to install industrial air heaters in your workshop. They are specially designed for tall spaces.
Material warehouse: many material warehouses have poor ventilation, and some are directly underground warehouses. They are easy to be wet without sunshine, especially in winter. At this time, it is only necessary to equip an industrial air heater in the material warehouse, which can not only keep warm, but also moisture-proof and dry. The key is to move easily and facilitate the oil mine: for some workers working under the mine, the underground working environment is very bad. Only by improving the working environment can work efficiency be improved, so the heating project is launched, In order to bring greater economic benefits to business owners. At the same time, for some energy mines, it is more related to heating safety, but the industrial heating function is very good and competent for this work
In China's current valve market, high-pressure valves still need to rely on imports, except for low-pressure valves that are acceptable in the international market. Under the continuous optimistic view of the macro-economy, most of the valve industry's production and sales indicators have maintained rapid growth. However, affected by the price war, the industry's sales revenue and profits have dropped significantly from the same period of last year. With the recovery of the world economy, China's valve products have also experienced an increase in imports and exports. However, due to the large gap between high-end technology and foreign manufacturers, the product technology will become a constraint on the development of China's valve products in the future. bottleneck.
