Available in PDF, EPUB and Kindle. Book excerpt: In this work, the dynamics of a poppet-type relief valve are studied for the purposes of generating an accurate linear model and stability criterion that may be used in design and simulation of hydraulic systems. This study begins by developing a flow rate model for the fluid flow through the valve. Next, a nonlinear model of the valve system, including the steady and transient flow forces that act on the poppet, is developed. From here, a linearized third order model is produced from which a stability criterion for the system is deduced using the Routh-Hurwitz method. The nonlinear and linearized models are compared using simulation studies. The simulation studies show the accuracy of the linear model. Design sensitivity analysis is performed, and recommendations are made that lead to improved stability characteristics of future valve designs. The linear model is shown to be valid for sufficiently stable systems. The stability criterion is shown to be valid for the system under consideration.

Download or read book A Quick Guide to Pressure Relief Valves PRVs written by Clifford Matthews and published by John Wiley & Sons. This book was released on 2005-07-22 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: This indispensable book systematically guides you through Pressure Relief Valves and how they work. It shows how protective devices perform an important function in preventing the accumulation of overpressure that can result in failure and the uncontrolled release of stored energy. They are therefore categorised as safety critical items of engineering equipment. The book goes on to show that their design and testing is heavily controlled by published technical standards because many countries are covered by statutory legislation. The content of the book shows that service damage and degradation mechanisms are outlined for various applications – PRVs and bursting discs are used in a wide variety of process conditions, ranging from clean service to heavily corrosive process fluids. This results in a correspondingly large number of damage mechanisms that can prevent them from working if they are not inspected and tested correctly. Risk based inspection procedures are introduced in this book as a method of minimising the chances of failure, and therefore maintaining high levels of safety. This Quick Guide to Pressure Relief Valves is intended to provide easily accessible technical information for engineers and technicians involved in the operation, testing and maintenance of pressure systems. It also covers other types of protective devises such as bursting discs.
