The V-seal is also a lip seal. The device consists of three parts: the support ring, the seal ring, and the pressure ring. The standard angle of the V-ring is 90°, and 60° for special occasions. The support ring is an important part for supporting the V-shaped seal ring. The section is thick and strong, the size is accurate, and the concave angle and the V-shaped seal ring are the same (90°) or slightly larger so that the seal ring is stable.
V-seal has small working resistance, stable operation, high pressure, vibration and impact resistance, can meet the characteristics of different media and use conditions, multiple overlapping use, and by adjusting the pressure to obtain the best sealing effect.However, its frictional resistance is large and the structure is complex. It is suitable for reciprocating movement as the dynamic seal of the piston or piston rod.
