The V-shaped combined seal can achieve the best state of sealing and friction by adjusting the axial size of the gasket. The initial wear after long-term operation can be extended by adjusting the axial size. It is recommended that the adjustable axial size of the sealing cavity be designed to be 1.025L, and the adjustment amount is 7.5%L.
