Share  |

Client Profile

The Client
Gate Valve Manufacturer, Europe

The Objective
To perform structural analysis of the gate valve at room temperature and predict stress concentration at concerned regions.

The Solution
The accurate CAD model created by Hi-Tech’s engineering team was utilized to perform structural analysis, to investigate stress concentration across the valve assembly as well as individual components and its impact on the deformation values.

Software Used:
ANSYS Professional NLS 14.5

Structural Analysis of Gate Valve Assembly

Gate valves are often designed for cases where the motive fluid is supposed to possess high temperature. These High temperature fluids impact the structural strength of the valves, due to excessive stress generation and concentration in restrictive regions.

There is a possibility of the valve components to deform under such high thermal stresses and develop cracks in the assembly, leading the valve to fail prematurely. One of the expert valve manufacturing firms in Europe reached Hi-Tech to receive simulation solutions for their gate valve, designed to carry high temperature fluid.

Challenges

Engineering Solution

To ensure meaningful simulation results, the first priority was to develop an accurate CAD model and later use the model for simulation purposes. An important aspect of the simulation was to ensure that the boundary conditions matched with that of the real world situations, which was accomplished by expert analysts at Hi-Tech.

The structural analysis performed on the valve assembly as well as individual components, provided useful insights on stress generation and deformation values. A detailed evaluation was done to figure out stress concentration on concerned areas of the valve assembly, and the design was found to be within the safe stress limits.
