Process valve is a widely used process control equipment, and its control function is mainly achieved by changing the flow area of the flow channel. The complex flow characteristics inside the valve that change with the control process are intrinsic factors that affect its safety and reliability. This book conducts research on process valves from the aspects of basic theory, numerical calculation and experimental research for single-phase and solid-containing two-phase working conditions. It establishes a calculation method for the fluid dynamics characteristics of the process valve control process under single-phase working conditions, and obtains the control characteristics and internal flow characteristics of process valves with different structures. It establishes a calculation method for the solid-containing two-phase fluid dynamics characteristics and flow-induced wear of process valves, and obtains the two-phase flow characteristics in the valve and the wear characteristics of the internal flow channels. Provides theoretical and technical support for the design and reliable operation of process valves. This book can be used as a reference book for process valve teaching personnel and scientific researchers. It also has important reference and reference value for engineering and technical personnel engaged in process valve product design and practical application.
Reader comments
This book is really practical! It is very common for us couriers to run around the city every day delivering various goods, such as valves. This book studies single-phase and solid-containing two-phase conditions, providing an important reference for practical applications. I think this book is very helpful for people who are engaged in related work. And I can learn a lot of knowledge from the book, which may come in handy in life in the future! However, I don't like the theoretical part very much, it's a bit boring. Experimental research is more interesting. Overall, this is a valuable book.
