“…These simulations revealed a rich variety of flow phenomena such as secondary patterns, hydrodynamic instabilities, turbulent pressure fluctuations due to vortex shedding, etc. Meanwhile, many researchers started to apply CFD method in the design and analyze other types of valves like hydraulic control valves and servo valves [17][18][19][20][21]. For instance, Lisowski and Rajda [20] investigated the pressure loss during flow by hydraulic directional control valve constructed from logic valves.…”

Abstract:In this study, a numerical model is developed to investigate the fluid and dynamic characteristics of a direct-operated safety relieve valve (SRV). The CFX code has been used to employ advanced Keywords:Direct-operated safety relief valve, pressure vessel, blowdown, CFD, moving mesh Highlights:A dynamic CFD analysis of a direct-operated safety relief valve with moving mesh is presented.Conventional inlet assumption is replaced by a pressure vessel to provide more realistic condition.The whole operation process of the valve from open to closure is monitored and investigated.The authors believe that this is the first time that a complete simulation of a SRV has been published providing detailed insight to the governing flow processes and the ability to accurately quantify valve dynamics and valve performance only previously available using experimental methods.Effects of factors such as vessel volume, adjusting ring position and spring stiffness are compared.

“…Using a sufficient number of logic valves, theoretically, we can build a directional control valve for these advanced control functions [7,10,15]. Their assembly as a functional unit, such as four-port hydraulic directional control valve, is a relatively complex task [16]. Proposals of ready-made solutions are rare and, furthermore, does not take into account the applicable standards [17].…”

“…The ANSYS/Fluent software allows researchers to choose from a variety of models available including: k-ε, k-ω, Reynolds etc. In the case of flow through the directional control valve, k-ε model works well enough due to the fact that in the valve there are no conditions for the formation of laminar flow [5,8]. Thus, the k-ε turbulence model was chosen for the simulation study.…”

The article presents the evaluation of possibility of pressure losses reduction at the flow through a WEH22 hydraulic directional control valve. For this purpose, 3D models of flow paths were built using the Creo Parametric software. Then the models were used in the ANSYS/Fluent software to calculate pressure losses. The results of the analysis have allowed for determination of possibilities of pressure losses reduction without changing overall dimensions of the valve body.Keywords: hydraulic directional valve, computational fluid dynamics Streszczenie W artykule przedstawiono ocenę możliwości obniżenia strat ciśnienia przy przepływie przez rozdzielacz hydrauliczny WEH22. W tym celu zbudowano modele 3D dróg przepływowych, które wygenerowano za pomocą programu CREO Parametric, a następnie te modele wykorzystano w programie ANSYS/Fluent do obliczenia strat ciśnienia. Uzyskane wyniki analiz pozwoliły na określenie możliwości obniżenia strat ciśnienia bez zmian wymiarów gabarytowych korpusu rozdzielacza.Słowa kluczowe: rozdzielacz hydrauliczny, obliczeniowa mechanika płynów 158
