A kind of rotating ring flat-crushing type mechanical seal structure, including hollow shaft, housing, threeway end cap, bearing, rotary packing ring, quiet
Sealing ring, housing are bolted with threeway end cap and are integrated, and enclosure interior is stretched into the forepart of hollow shaft, inside housings
It is set in hollow shaft there are two bearing, bearing dottle pin is equipped between two bearings, two bearings are kept off by hole baffle ring and axis
Enclose /V.The close stationary seal ring of fitting and rotary packing ring, rotary packing ring relatively is equipped in the front end of hollow shaft by rotating ring to consolidate
Fixed set is connected with hollow shaft, and rotation stop pin is equipped between rotating ring fixing sleeve and hollow shaft, and rotating ring fixing sleeve is driven by rotation stop pin.
The rotating ring O-ring with sealing function is equipped between rotating ring fixing sleeve and hollow shaft.It, will by increasing a rotating ring fixing sleeve
The sealing station of rotating ring is transferred under sealing surface direction force, has thus reached a floating seal side for being similar to glue envelope
Formula, rotary packing ring can prevent from departing from rotating ring fixing sleeve under the pressure state of medium, using pressure difference, using rotation stop pin with
Rotating ring fixing sleeve rotation stop, while rotating ring fixing sleeve is driven by rotation stop pin, thus can not much utilize the shape of glue envelope
Under state, flat pressing structure is realized to large scale rotary packing ring, it is easy to process, it is at low cost, it is easy to maintenance.
Spring and elastic cylindrical pin are equipped between the rear end face of the stationary seal ring and threeway end cap, stationary seal ring passes through bullet
Spring compensates, and stationary seal ring passes through elastic cylindrical pin rotation stop.Tool is equipped between the joint face of stationary seal ring and threeway end cap
There is the stationary ring O-ring of sealing function.
The rotating ring fixing sleeve is cylindrical shape, is equipped with an annular projection in its inner surface, is equipped with before annular projection
Rotating ring embedded groove is equipped with rotation stop pin embedded groove behind annular projection.
The beneficial effects of the utility model are：Reasonable in design, good airproof performance, stability is high, can be much can not profit
In the state of being sealed with glue, flat pressing structure is realized to large scale rotary packing ring, it is easy to process, it is at low cost, it is easy to maintenance.
