At present, the valves commonly used in the production of various industries in our country are metal valves. The use of metal valves has a history of hundreds of years. Although the structure and materials have also been improved during this time, due to the limitations of metal materials, they are increasingly unable to adapt to high temperatures. The requirements of severe working conditions such as wear and strong corrosion are mainly reflected in short service life and serious leakage, which greatly affect the stability of system operation. Traditional metal valves urgently need to be completely reformed in terms of materials, design and manufacturing processes.

 

As a new material in the 21st century, advanced ceramic materials have been valued by more and more scientific workers. Applying it to industrial valves is a bold and beneficial innovation. Wenzhou Zhongli Valve Co., Ltd., as a leading enterprise specializing in the research, development, design and manufacture of ceramic valves, has always been at the forefront of the industry.

 

In recent years, in the fierce competition of the market economy, the company's new products have emerged. At present, more than a dozen new products have been developed, including wear-resistant slag discharge gate valves, ceramic globe valves, hard-sealed ball valves, ceramic gate valves, ceramic regulating valves, ceramic stop A number of products such as check valves and ceramic ball valves have obtained national patent certificates.

According to Zhang Zhongfang, chairman of Zhongli Valve Company, the new ceramic valve has four major advantages: First, the high-tech new ceramic structural material is used to make the sealing and vulnerable parts of the valve, which improves the wear resistance, corrosion resistance and The tightness greatly extends the service life of the valve. Second, the use of ceramic valves can greatly reduce the number of valve replacements, improve the safety and stability of supporting equipment operating systems, reduce the labor intensity of workers, and save equipment repair costs. Third, the use of ceramic valves can improve the tightness of industrial piping systems, and at the same time can prevent leaks to the maximum, which will play a positive role in promoting environmental protection. Fourth, the raw materials for manufacturing ceramics are extensive and the cost is low. Ceramics with excellent properties can be manufactured with common elements such as aluminum, carbon and silicon, which can save a lot of metal materials and rare mineral resources.

 

The new ceramic valve is mainly used in industrial fields such as electric power, petroleum, chemical industry, metallurgy, mining, sewage treatment, etc., especially in the face of severe working conditions such as high wear, strong corrosion, high temperature and high pressure, it shows its excellent performance. It can meet the high abrasion and strong corrosion environment, especially the outstanding feature is its long service life, and its performance-price ratio is far superior to similar metal valves. With the continuous development and progress of science and technology, ceramic material formulation, molding, processing and assembly technology and other aspects of technology have become more mature and complete, and ceramic valves have been more and more recognized by the industry for its excellent performance.

 

Zhang Zhongfang said that the ceramic valves produced by Zhongli Valve Company are currently mainly used in large projects at home and abroad. Market prospects. The new technology and projects developed by the company have continuously attracted the attention and cooperation of the industry and domestic and foreign research institutes.
