Nonlinear sealing force of a seawater balance valve used in an 11000-meter manned submersible

Frontiers of Mechanical Engineering 2023, Volume 18, Issue 1, doi: 10.1007/s11465-022-0726-y

Abstract: Balance valve is a core component of the 11000-meter manned submersible “struggle,” and its sealing performanceThe increasing sealing force improves the sealing performance and increases the system’s energy consumptionA hybrid analytical–numerical–experimental (ANE) model is proposed to obtain the minimum sealing forceThe effects of roundness error, environmental pressure, and materials on the minimum sealing force areguiding significance for evaluating the sealing performance of ultrahigh pressure balance valves.
