A kind of shock resistance whirl compensator, comprise inner tube, outer sleeve, connecting tube, filler flange, outer sleeve suit on inner pipe, insert in connecting tube through outer sleeve one end of inner tube, connecting tube is reducer pipe and is connected with outer sleeve, filler flange suit on inner pipe, its one end is stretched in outer sleeve, the internal surface of outer sleeve is provided with annular inner convex platform, at this annular inner convex platform and filler flange, stretch between one end of outer sleeve and be provided with stuffing box packing, between stuffing box packing and annular inner convex platform, be provided with impact-resistant panels.
For the ease of the relative rotation between inner tube and outer sleeve, in inner tube, stretch on the outer surface of one end of connecting tube and be provided with an annular outer platform, in the cavity forming between annular outer platform and annular inner convex platform, be provided with ball or slip ring is set.
For the ease of further improving sealability of the present utility model, in the cavity that can form, edge face sealing member is set between aforementioned annular outer platform and annular inner convex platform.
For fear of stuffing box packing in long-term use because normal wear produces space, thereby affect the sealability of whole whirl compensator, also filling device can be set on outer sleeve.
For prevent product in project installation process, produce the ball displacement that arranges between dislocation in the other direction and inside and outside annular boss, come off or inside and outside annular boss between the slip ring, the displacement of edge face sealing member that arrange, in connecting tube, be provided with limiting stopper.
In order to ensure the shock resistance of impact-resistant panels, the internal diameter size of impact-resistant panels is greater than inner tube external diameter 1-0.5mm, and external diameter is less than outer sleeve internal diameter 1-0.5mm.
The utility model, by the setting of impact-resistant panels, can effectively be resisted the impact of medium to stuffing box packing, thereby reduces the loss of sealing material, has improved the sealing of whole whirl compensator.
