Latch is equipped in seal ring seat and sealing ring counterface, it is gearing to realize；It is added in sealing ring mating surface
Groove, to coordinate the latch in ring seat；In sealing ring and the built-in mating surface of ring seat plus step, to coordinate L-type circle.It realizes
When pumping idle running, will not be loosened between mechanical sealing linkage ring and rotating seat, stationary ring and stationary seat, mechanical seal will not be revealed.
Fit system between the technical program rotating ring and rotating seat, between stationary ring and stationary seat becomes L-type from gluing
Circle cooperation latch, leakage caused by preventing dynamic and static ring dry grinding fever, reaches good heat resistanceheat resistant leak preventing effect, it is ensured that entire machine envelope
Normal work, increase machine envelope maintenanceability, when seal wears generate leakage need to re-grind sealing ring when, to knot
Structure is more easily dismantled, workover rig envelope, is prolonged the service life and is improved reliability.
