Currently, the domestic valve industry research and development capabilities are still weak, the basic method to stay on experience in design, product development can only be digested and absorbed some foreign reference design information and samples of new products in the true sense of self-development work rarely. The reason is the lack of design guidance and involvement of high-paying technology means new theory, but also a lack of investment in high-performance parameters, temperature parameters of dynamic simulation tools and test equipment Shandong valves, basic research is also small. Elastic Ball Ball: The ball valve is elastic. Ball and seat ring are made of metal materials V-ball manufacturers, sealing pressure than large, rely on the media itself has reached less pressure sealing requirements, must apply force. This valve is suitable for high temperature and high pressure medium. Elastic sphere is the sphere of the inner wall at the lower end of a resilient open slot, and access flexibility. Valve Co., Ltd. Shandong China Everbright production of such types of valves wide range of applications, reliable quality, no internal leakage, leakage phenomenon, frequent switching is not stuck, rust, the majority of chemical plants, thermal power plants, steel mills, printing and dyeing, the best choice of food plants.
