Liaoning Valve Valve is produced with the production of fluid pipelines. Humans have used valves for nearly 4,000 years. In ancient China, when brine was used to make salt from salt wells, wooden plug valves were used in bamboo pipelines. In 1800 BC, when the ancient Egyptians built large-scale water conservancy to prevent the Nile from flooding, they used similar wooden cock to control the distribution of water flow. These are the prototypes of the valve. The large number of applications of industrial valves began after Watt invented the steam engine. In the early twentieth century, valves made of cast iron, cast steel, forged steel, stainless steel, chromium molybdenum steel, brass and other materials appeared. Used in various industries and various working conditions. There are not many companies that first introduced foreign valve production technology in China. Later, the introduction of foreign production technology has made breakthroughs in domestic valve production technology, improved quality, and extended life.

 

According to the "Bottlenecks in the Competitive Development of China's Valve Industry in 2013", as the pace of restructuring of the valve industry accelerates, the future industry will be a competition between valve product quality and safety and product brands, and the products will become high-tech, high-parameters, and strong corrosion resistance. , Development in the direction of long life, only through continuous technological innovation, development of new products, and technological transformation, can we gradually improve the technical level of products, meet the needs of domestic equipment, and fully realize the localization of valves. Under the huge demand environment of my country's valve manufacturing industry, it is bound to show better development prospects.

 

At present, the turnover of my country's valve market is as high as 50 billion yuan, which fully demonstrates the scale and momentum of the development of my country's valve industry. However, in the context of a good industrial situation, there are also some problems worthy of our worry, especially the valve companies in my country are mainly low-level, small-scale, family-based enterprises. This is a big limitation and bottleneck for the future development of my country's valve industry.

 

At present, domestic key valve manufacturers have been able to design and manufacture various valves in accordance with international standards such as ISO international standards, DIN German standards, AWWA American standards, and some manufacturers' products have reached the international advanced level. Although the overall level of the valve industry in the New Year has been greatly improved, the quality is not stable enough, such as running, leaking, dripping, and leakage often appear in domestic valves.
