Comparative analysis of leakage calculations for metallic seals of ball-seat valves using the multi-asperity model and the magnification-based model

The leakage characteristics of metallic seals have a significant influence on valve performance. The contact status along the sealing zone greatly affects sealing properties, but is still not fully understood in current studies. There are mainly two different models for the seal’s contact mechanics:...

The contact status along the sealing zone greatly affects sealing properties, but is still not fully understood in current studies. There are mainly two different models for the seal’s contact mechanics: the multi-asperity model and the magnification-based model. This paper conducted a comparative analysis of leakage calculations for metallic seals of ball-seat valves based on the above two contact models. The test rig for measuring leakage values at different pressures has been constructed. The simulation with/without considering plastic effects is presented and verified by the experiment. The results indicate that the magnification-based model, with the consideration of plastic effects, can provide a better coincidence with experimental results.

The contact status along the sealing zone greatly affects sealing properties, but is still not fully understood in current studies. There are mainly two different models for the seal’s contact mechanics: the multi-asperity model and the magnification-based model. This paper conducted a comparative analysis of leakage calculations for metallic seals of ball-seat valves based on the above two contact models. The test rig for measuring leakage values at different pressures has been constructed. The simulation with/without considering plastic effects is presented and verified by the experiment. The results indicate that the magnification-based model, with the consideration of plastic effects, can provide a better coincidence with experimental results.

abstract	The leakage characteristics of metallic seals have a significant influence on valve performance. The contact status along the sealing zone greatly affects sealing properties, but is still not fully understood in current studies. There are mainly two different models for the seal’s contact mechanics: the multi-asperity model and the magnification-based model. This paper conducted a comparative analysis of leakage calculations for metallic seals of ball-seat valves based on the above two contact models. The test rig for measuring leakage values at different pressures has been constructed. The simulation with/without considering plastic effects is presented and verified by the experiment. The results indicate that the magnification-based model, with the consideration of plastic effects, can provide a better coincidence with experimental results.
