Abstract

PURPOSE: To obtain mechanical seal of effective seal by providing an opposite end of the sealed end of seal ring with flexible sheet of graphite, and if necessary, with O-ring around seal ring.
CONSTITUTION: For instance, a seal ring 3 is incorporated within a seal cover 1, and a sheet 7 which is made in shape of a plate from flexible graphite, is inserted between the seal cover 1 and an opposite end of a sealed end 10 of the seal ring 3. Also, as an auxiliary, O-ring 5 is provided between upper face of seal ring 3 and the seal cover 1, to consist a mechanical seal. This construction reduce deformation the seal, provides the seal with absorption against sxial vibration, eliminates fluid leakage, sealed ends and lessen temperature increase at sealed end, because of good heat radiation.
