“…By analyzing the force characteristic, both displacement and final position of the valve spool were predicted successfully. Song et al [19,20] proposed a method that can simulate the complete transient-flow process of a safety relief valve, from opening to closing. The group also found that the volume of the container, the spring stiffness, and the position of the adjustment ring affects both release volume and release time.…”

In high-pressure hydrogen systems, the check valve is one of the most easy-to-damage components. Generally, the high-pressure hydrogen flow can generate a strong impact on the check valve, which can cause damage and failure. Therefore, it is useful to study the transient flow characteristics of the high-pressure hydrogen flow in check valves. Using dynamic mesh generation and the National Institute of Standards and Technology (NIST) real hydrogen gas model, a transient-flow model of the high-pressure hydrogen for the check valve is established. First, the flow properties of high-pressure hydrogen during the opening process is investigated, and velocity changes and pressure distribution of hydrogen gas flow are studied. In addition, the fluid force, acceleration, and velocity of the valve spool are analyzed quantitatively. Subsequently, the effect of the hydrogen inlet-pressure on the movement characteristic of the valve spool is investigated. The results of this study can improve both the design and applications of check valves in high-pressure hydrogen systems.

This article presents detailed experimental results of the influencing factors of flow rate, set pressure, and inlet pipe length of a pressure relief valve. In order to analyze the influence of different flow rates on the instability characteristics of pressure relief valve, the multi-stage output of pump flow is realized. In terms of modeling, we investigated the theory concerning instability in the system: the 3% rule boundary. Data analyses on typical stable, cycling, and chatter instability conditions are conducted. The stable boundaries of the 3% rule and the quarter-wave model are drawn, which are consistent with the experimental results.

“…Results of the tested range of conditions indicate that the flow and force characteristics of the safety valve are significantly influenced by the flow rate. Modelling and analysis of safety valves using computational fluid dynamics (CFD) and fluidstructure interaction (FSI) techniques related to a spring-loaded pressure valve was the subject of Song's article (Song et al, 2015). Similarly, Scuro (Scuro et al, 2018) provided CFD analysis of a directly-operated safety relief valve, while Beune (Beune et al, 2012) analyzed opening of a high-pressure safety valves by the means of both CFD and FSI.…”

This article presents results of numerical modelling, simulation and test bench experiments of a hydraulic direct-acting relief valve was used as a safety valve. The analyzed safety valve was placed in a system consisting of a fixed-speed pump, a control valve, a hydraulic cylinder as an actuator and a second pressure valve in the load line used as a payload generator for the cylinder. In the first step mathematical model of the system was formulated in the form of a system of ordinary differential equations. Next, simulation model was created in Matlab/Simulink. Simulations were carried out for different values of the actuator payload. The obtained results include time series of pressure, flow rate and displacement of the actuator piston. In order to confirm simulation results, a test bench was built and series of experiments were carried out. High compliance of simulation and laboratory results was obtained. It was confirmed that the proposed solution with the relief valve used as a safety valve fulfills its task of protecting the hydraulic system from excessive pressure increase.
