V-type fluororubber cloth oil seal

The V-shaped sealing ring has a V-shaped section and is also a lip-shaped sealing ring. The V-shaped sealing device consists of three parts: support ring, sealing ring and pressure ring. The standard angle of the V-shaped seal is 90°, and 60° is also used in special occasions. The support ring is an important part to support the V-shaped sealing ring. Its section is thick and strong, the size is accurate, and the concave angle is the same (90°) or slightly larger than that of the V-shaped sealing ring, so that the sealing ring can be placed stably. The function of the pressure ring is to create an initial compression amount for the V-shaped sealing ring to make it fully contact with the sealed surface, and to adjust the compression amount of the V-shaped sealing ring. EUB Industrial Design. China In the free state, the outer diameter of the lip of the V-ring is larger than the inner diameter of the packing cavity, and the inner diameter of the lip is smaller than the outer diameter of the piston rod. In this way, there will be some deformation after assembly. Due to the action of the support ring, this deformation occurs only at the tip of the lip and at its junction...)
