Disc springs are conical discs used as sealing aids. They can be used individually or in series or parallel.
They bear static or dynamic loads along the axial direction at the upper inner edge and lower outer edge. When compressed, they deform until they are flattened, storing energy as a live load. When necessary, they automatically convert into additional compressive loads required for sealing, reducing the continuous tightening requirements of gaskets and packings, and minimizing unnecessary downtime and leakage losses.
