Abstract
A lip-mouth type filling seal is a strip made from polymer composites. The strip can be circled into a seal ring. The filling seal consists of a strip undersurface and a plurality of strip-shaped lip mouths extruding towards the upper left and upper right arranged on the undersurface. The utility model has simple structure, low cost, good seal performance and long service life. When in use, the lip mouth closely clings to the shaft and is coiled around the shaft. The head and tail ends are felted together and form a seal ring.
Description
Technical field
The utility model belongs to the shaft sealing technical field.
Background technique
Known to the claimant, the present machinery diameter of axle is more than 1 meter, or the running shaft of axle two ends connected element inconvenience dismounting, and its Sealing all adopts packing type, as wool felt, and graphite packing etc.Nonelastic because of above-mentioned filler, only depend on its volume to fill sealing, the seepage phenomenon often appears in actual use, can not reach seal request, strengthened maintenance cost.
Summary of the invention
The purpose of this utility model to provide exactly a kind of rational in infrastructure, can solve leakage problems effectively, can improve working life the lip type packing seal element that cost is low again.
The utility model is design like this: a kind of lip type packing seal element, be characterized in: it is a kind of rectangular thing that circularizes seal ring that encloses of being made by polymer composite, by the long strip bottom surface and be located at a plurality of long strip lips that stretch out to upper left side, upper right on the bottom surface and constitute.During use lip is close to axial plane and is around on the axle, and make its head and the tail end face bond together the use of formation seal ring.
Because the utility model is the temperature according to sealing medium, pressure and characteristics, a kind of rectangular thing that circularizes seal ring that encloses that adopts corresponding polymer composite to make, so simple and reasonable, cost is low; Because the utility model is around on the axle when using, and make the head and the tail bonding, form seal ring, be provided with a plurality of long strip lips, thus good airproof performance, long service life.

Fig. 2 is an External view of the present utility model.
The bottom surface of 8. 9. left lip 10. bearings 11. Sealings of 1. bearing housings, 2. left spring 3. lip type packing seal elements, 4. right spring 5. Glands, 6. right lip 7. draught fan impellers among the figure
Embodiment
From Fig. 2 as seen, the utility model is strip, it by the cuboid bottom surface 11 of long strip and be located at long strip above it left, the left and right lip 9,6 of Υ shape that stretches out of right constitutes, it can be an inner ring circle seal ring circlewise with two lips.
From Fig. 1 as seen, during use lip of the present utility model is close to axial plane around 8 one weeks of axle, 96% intercepting by the axle girth, both ends of the surface are coated Bond, slightly execute pulling force, make both bonding formation seal rings, again at the left and right spring 2,4 of the scrobicular ring place of left and right lip 9,6 suit, will lip and axial compression push in the packing cavity after tight, load onto Gland 5 and compress.
During work, when axle 8 rotations, oil flows out to the right along axle 8 from bearing 10, is tightly sealed by a left side, first road of lip type packing seal element 3 lip 9.When under high pressure sealing, a left side, first road of lip type packing seal element 3 lip 9 is slightly to internal strain, and the cavity pressure between the right lip 6 in first road left side lip 9 and second road strengthens, and the lip inside and outside differential pressure diminishes, thereby has improved the lip seal effect.When being negative pressure in the equipment, the right lip 6 in second road at first seals, and its principle is identical.
The end surface shape of long strip of the present utility model bottom surface also can be ellipse, and the lip number also can be more than two.
Medium in the equipment can be selected the lip type packing seal element of making of different materials for use according to the physico-chemical property of medium not simultaneously.
Claims (4)
1, a kind of lip type packing seal element is characterized in that: it is a kind of rectangular thing that circularizes seal ring that encloses of being made by polymer composite, by the long strip bottom surface and be located at a plurality of long strip lips that stretch out to upper left side, upper right on the bottom surface and constitute.
2, a kind of lip type packing seal element according to claim 1, it is characterized in that: the end surface shape of described long strip bottom surface is a rectangular.
3, a kind of lip type packing seal element according to claim 1 is characterized in that: the end surface shape of described long strip bottom surface is for oval.
4, a kind of lip type packing seal element according to claim 1 is characterized in that: described a plurality of long strip lips are two Υ shape lips.
