Research and Development of New Type of Sleeve Control Valve

Abstract: Control valve, also known as the control valve, is the final control of the pipeline in the process, in various industries have a wide range of applications. With the rapid development of the market, the demand for the valve is constantly increasing, while the requirements of the valve products are also getting higher and higher. The existing control valve in the application process there are many problems, such as leakage, easy to plug the card, the flow coefficient is small, the adjustment range is small, vibration, howling and so on. This is a great constraint on the development of the control valve. This paper analyzes the internal characteristics of the control valve from the overall structure of the control valve and finds the key factors that affect the dynamic characteristics of the control valve. This has important theoretical and practical value for the development of the control valve. This paper mainly designs a new type of sleeve type regulating valve, the hole on the sleeve is shaped hole.

KeyWords:Newcontrolvalve；characteristic；structure；Straight hole。
