Abstract
The utility model relates to a shaft sealing device which belongs to a sealing device. In the utility model, one end of a spiral spring is sheathed on an annular spring seat, and the other end of the spiral spring is sheathed on the lower end of a sleeve ring; a movable sealing ring is arranged in the sleeve ring in a sitting way, an upper opening of the movable sealing ring is embedded and provided with a movable sealing pad in a tight matching way; a lower opening of a stationary sealing ring is embedded and provided with a stationary sealing pad in a tight matching way, and the ring surfaces of the movable sealing pad and the stationary sealing pad contact each other in a fitting way. An outer shoulder of an upper opening of the stationary sealing ring is sheathed with an elastic sealing ring, and an elastic sealing ring is embedded in a ring gap between an inner shoulder of the movable sealing ring and an inner shoulder of the sleeve ring. With the adoption of the utility model, the frictional resistance of shaft seal is reduced and the sealing effect is improved. The utility model has the advantages of energy saving, consumption reduction, overhaul period extension, movable equipment efficiency improvement, etc.
Description
Technical field
The utility model belongs to seal arrangement, particularly a kind of shaft sealer.
Background technique
Existing shaft sealer all adopts packing compression type sealing, is that its shortcoming is: frictional resistance is big, energy loss is high with the ring Zhou Zuowei static and dynamic sealing face of axle, and packing working life is short, maintenance is frequent, waste material, equipment operation cost height.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of shaft sealer is provided, and is anchor ring static seal, the cross-section radial motive sealing that the anchor ring static and dynamic sealing mode of axle is become axle, and the rotation frictional resistance of axle is significantly reduced.
The technical solution adopted in the utility model is: a helical spring end is placed on the annular elastomeric spring abutment, and the helical spring the other end is placed in the lower end of the collar.The motive sealing ring seat is in the collar, at the drive fit setting-in motive sealing pad suitable for reading of rotary packing ring; At the end opening drive fit setting-in static seal pad of stationary seal ring, the motive sealing pad matches with the anchor ring of static seal pad and contacts.At stationary seal ring outer shoulder place suit elastic sealing ring suitable for reading, embedded the shooting property seal ring of annular space between the inner shoulder table of the inner shoulder table of rotary packing ring and the collar.
Further change as of the present utility model, the lower wall of annular elastomeric spring abutment has the radial penetration spiral pin, in the upper edge of stationary seal ring bayonet socket is arranged, and on the outer wall of the collar and the sidewall of corresponding rotary packing ring the draw-in groove that agrees with is mutually arranged.
The technical solution of the utility model is with the annular dynamic and static sealing means between axle and housing, has constituted annular static seal by two seal rings.And the section of motive sealing with axle sealed and replace.The seal arrangement of this structure has reduced the frictional resistance of shaft sealing, has significantly improved sealing effect, have energy-saving and cost-reducing, prolong the repair cycle, improve advantage such as moving device efficiency.
Description of drawings
Figure of description is the structural representation of shaft sealer of the present utility model.
Embodiment
As seen from the figure, of the present utility model is that an end of helical spring 1 is placed on the annular elastomeric spring abutment 2, and the other end of helical spring 1 is placed in the lower end of the collar 3.4 of rotary packing rings are in the collar 3, at the drive fit setting-in motive sealing pad 5 suitable for reading of rotary packing ring 4; End opening drive fit setting-in static seal pad 7 at stationary seal ring 6.Motive sealing pad 5 matches with the anchor ring of static seal pad 7 and contacts.At stationary seal ring 6 outer shoulder place suit elastic sealing ring 8 suitable for reading, embedded the shooting property seal ring 11 of annular space between the inner shoulder table 10 of the inner shoulder table 9 of rotary packing ring 4 and the collar 3, wherein, the lower wall of annular elastomeric spring abutment 2 has radial penetration spiral pin 12, in the upper edge of stationary seal ring 6 bayonet socket 13 is arranged, on the sidewall of the outer wall of the collar 3 and corresponding rotary packing ring 4 draw-in groove 14 that agrees with is mutually arranged.
