The surface of the manual cast steel hard-sealed ball valve body adopts advanced spraying technology, and the highest hardness can reach HRC78 after various treatments. The processing of the valve seat's sealing surface can make the trunnion ball valve's hardness reach HRC72. The ball and valve seat are paired and ground, and all sealing areas of the entire sealing surface of the ball valve are precision ground. The hard sealed manual trunnion ball valve is suitable for high-temperature and high-pressure water, steam, petroleum, coal, fibers, corrosive media, and media with particles. The metal sealed ball valve has two structures such as floating balls and fixed balls. The metal seat ring is in contact with the spherical surface, and the seat ring and the spherical surface are sealed by the uniform spring load acting on the seat ring.
In many current technical applications, safe and efficient starting devices have been better developed. For example, a valve can achieve repeated opening and closing of the valve based on pneumatic energy. The corresponding fluid control solutions in the chemical process are more abundant by using this hard-sealed manual trunnion ball valve. The application of the hard-sealed manual trunnion ball valve provides a better solution for the management and safety control of industrial fluids.
The advantages of the hard-sealed manual trunnion ball valve
(1) The hard-sealed manual trunnion ball valve can better improve the safety and reliability of the overall design of the pipeline.
During operation, pneumatic devices can convert kinetic energy into motion without the need for power and a source of ignition. In some chemical and petroleum fields, there are higher requirements for spark and combustion monitoring. This hard-sealed manual trunnion ball valve can be controlled by compressed gas movement. Therefore, in a flammable and explosive environment, the hard-sealed manual trunnion ball valve can have a better safe use effect, making the entire pipeline and the use effect of the flowing medium safer.
(2) Improve the durability and effectiveness of the valve.
Through the investigation of the current manufacturers of hard-sealed manual trunnion ball valves, it can be found that the device of this kind of ball valve is relatively simple and has good maintenance ability during use. At the same time, the system method can ensure its long service life due to its simple structure, much wear, and good repair and recovery capabilities of parts. In the case of long-term use of the equipment, hard sealed manual trunnion ball valves can also save the overall cost and are easily maintained and replaced. Therefore, this hard-sealed manual trunnion ball valve brings more high-quality and low-cost equipment to the cost control of its pipelines.
In a word, using a reliable valve manufactured by Xinhai Valve can not only maintain the safety of the valve, but also obtain a good experience in the use of pneumatic devices. Therefore, with the help of the working mechanism of the manual hard sealed trunnion ball valve, we can obtain high-quality products, and apply them to the modern industrial field according to the performance of these products so as to better improve the control accuracy and repeatability of modern industrial valves.
