Abstract:

The structural integrity of valves that are used to control cooling waters in the primary coolant loop that prevents boiling within the reactor in a nuclear power plant must be capable of withstanding earthquakes or other dangerous situations. In this study, numerical analyses using a finite element method, that is, static and dynamic analyses according to the rigid or flexible characteristics of the dynamic properties of a 200A butterfly valve, were performed according to the KEPIC MFA. An experimental vibration test was also carried out in order to verify the results from the modal analysis,

Abstract:

A concentric double-flange butterfly valve (DN-500, PN-10) was analyzed to examine its dynamic behavior and internal fluid flow across multiple opening angles. Finite Element Analysis (FEA) was employed to determine natural frequencies, mode shapes, and effective mass participation factors (EMPFs) for valve positions at 30°, 60°, and 90°. The valve geometry was discretized using a curvature-based mesh with linear elastic isotropic properties for 1023 carbon steel. Lower-order vibration modes produced global deformations primarily along the valve disk, while higher-order modes showed localized

Abstract Zero output technology is extensively used to expand heating capacity and electric peak shaving for low-pressure cylinders in thermal power plants. Problems of communicating pipe vibration under a small volume flow rate are common. In this paper, the optimal structure of the butterfly valve plate with diversion is proposed, and the numerical simulation under the condition of maximum vibration is carried out by CFD. The results show that after the structure optimization, the steam flowing from the butterfly valve plate along the flow direction is no longer attached to the valve disc, a

The link rod butterfly valve relies on the link mechanism inside the flow channel to realize opening. The flow within flow channel is complex and the flow state is uncertain, so that pressure load of the flow part can't be determined in the butterfly valve designing, and strength of the parts can’t be calculated accurately and the thrust of the hydraulic cylinder can't be determined accurately. Therefore, it is necessary to carry out flow field analysis.

Abstract:

Valves are important components in controlling the amount of fluid going to devices. One of these types is the butterfly valve (BFV) that adjusts the amount of flow by rotating the valve disk by means of its shafts which is usually located in the middle of the flow. Despite its common usage in various applications, the BFV is known to cause a high-pressure drop. Conversely, the pinch valve is another type of flow control device that uses a pinching mechanism to open and close the inner tube by pinching at different degrees.

Abstract:

A multistage pressure reducing valve is presented in this paper. The pressure reducing components are specially designed to not only control the flow rate but also effectively prevent the cavitation vibration. However, when the fluid flows through the pressure reducing components, the divergence and shedding of the vortices in the flow field seriously affect the stability of the valve and cause vortex-induced vibration. Especially, the main frequency of the vortex shedding is in the same frequency range as the modal frequency of the valve, the vortex-induced resonance of the valve occurs. It s

Abstract:

Flow-induced vibration widely exists in fluid power machinery, and there is a great relation between the vibration and engineering construction. In this paper, prototype valve experiment and three-dimensional simulation has been done on the pre-opening sleeve valve. High-frequency minute dynamic pressure sensors are adopted in the valve in experiment. Vibration data with dynamic pressure in different conditions are collected and measured to find out the pulsation characteristics of the valve disc during the experiment. Meanwhile, three-dimensional numerical simulation and analysis on the inter

Abstract:

In the present study, the flow characteristics of butterfly valves with different sizes DN 80 (nominal diameter: 76.2 mm), DN 262 (nominal diameter: 254 mm), DN 400 (nominal diameter: 406 mm) were numerically investigated under different valve opening percentages. Representative two-equation turbulence models of two-equation k-epsilon model of Launder and Sharma, two-equation k-omega model of Wilcox, and two-equation k-omega SST model of Menter were selected. Flow characteristics of butterfly valves were examined to determine turbulence model effects. It was determined that increasing turbulen

Abstract:

The wheel brake device is one of the most widely used landing deceleration devices in modern aircraft. For large aircraft, a multivalve parallel brake system is usually used. When a brake pressure servo valve of a certain type of aircraft is debugged, the output brake pressure of the system shows obvious periodic oscillation with constant amplitude. This paper focuses on the brake pressure servo valve, which is the key component of the system. There are a large number of feedback and adjustment segments in the brake pressure servo valve, which can not only improve the control accuracy but also

Abstract:

This paper investigates the failure of a regulating valve stem in a petrochemical plant, which was mainly caused by vibration fatigue under small opening conditions. The fractured valve stem was analyzed using macroscopic analysis, chemical composition analysis, mechanical property analysis, metallographic analysis, fracture surface observation, and energy spectrum analysis. Additionally, fluid-structure interaction (FSI) modal analysis was used to investigate the failure of the regulating valve. The results indicate that the valve opening had a direct impact on the vibration of the valve body

Abstract:

Based on the computational fluid dynamics(CFD) technique, the three-dimensional inner flow field of a large-sized throttle valve was built and the dynamics characteristics of the control valve were analyzed. The results indicate that the main reason for the spool and valve vibration was the cavitations at the spool and the whirlpool flow at the outlet of the valve, and the fluid velocity rises as the decreasing of the flow area at the same opening. The research f indings will provide the theory basis for the later throttle valves development and optimization with littler vibration and higher e

Abstract:

Variable stiffness f2mc are investigated for vibration isolation through analysis and experiments. The f2mc are novel structures that have been shown to achieve significant changes in stiffness through simple valve control. The objective of this research is to develop analysis tools to investigate the f2mc variable modulus system for semi-active vibration isolation and to validate the results through experiments. A non-linear analytical model of an isolation mount based on the f2mc tube with a proportional valve is developed. Analysis results indicate that the f2mc-based isolation mount is eff

Abstract:

We have performed a shape optimization of the disc in an industrial double-eccentric butterfly valve using the effect analysis of design variables to enhance the valve performance. For the optimization, we select three performance quantities such as pressure drop, maximum stress, and mass (weight) as the responses and three dimensions regarding the disc shape as the design variables. Subsequently, we compose a layout of orthogonal array (L16) by performing numerical simulations on the flow and structure using a commercial package, ANSYS v13.0, and then make an effect analysis of the design var
