Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment's mode of execution is clearly and completely described.
Figure 2 shows that the structural representation of the apex combustion seal that the utility model embodiment provides.As shown in Figure 2, this apex combustion seal comprises: rotating ring 11 and two stationary rings 12, two stationary rings 12 interlock, rotating ring 11 of therebetween, wherein rotating ring 11 seals Chi14 road number and stationary ring 12 and seals Chi13 road number and equate or differ together, and is at least (there is shown three roads) together, sealing wing 13 cross sections of the sealing wing 14 of rotating ring 11 and stationary ring 12 are taper, cross arrangement, to improve sealing wing axial rigidity, seals wing while preventing real machine operation and occurs the phenomenon of being completely cured.
Wherein, rotating ring 11 and stationary ring 12 are made up of nonmetal sealing material, and stationary ring 12 and sealing wing 13 can directly be processed on main frame body, can significantly reduce axial dimension, dwindle main frame bearing span distance, improve main frame rigidity.
Figure 3 shows that the structural representation of the apex combustion seal that the utility model one embodiment provides.As shown in Figure 3, this apex combustion seal further comprises on the basis of Fig. 2 shown device: rotating ring 15 and corrugated plate 16 float, the rotating ring 15 that floats is arranged on rotating ring 11, float and be connected with corrugated plate 16 between rotating ring 15 and rotating ring 11, rotating ring 11 is that rigidity coordinates installation with axle, axle is play vertically, becomes adaptive by the bullet of corrugated plate.
Figure 4 shows that the structural representation of the apex combustion seal that the utility model one embodiment provides.As shown in Figure 4, this radial device further comprises on the basis of Fig. 3: stuffing box packing 17, O shape circle 18, stuffing box packing 17 is bonded in bottom land, prevent stuffing box packing rotation slippage, rotating ring 11 seals wing 14 and stationary ring 12 and seals wing 13 and directly contact with stuffing box packing 17, forms micro-interference fit state, makes seal operation state in the critical contact sealing state between contact sealing and non-contact sealing.Rotating ring 11 is that rigidity coordinates installation with between centers, rotating ring 11 and O shape circle 18 sealings between centers.
Figure 5 shows that the structural representation of the apex combustion seal that the utility model one embodiment provides.As shown in Figure 5, sealing device further comprises on the basis of Fig. 2: stuffing box packing 17, O shape circle 18, stuffing box packing 17 is bonded in bottom land, prevent stuffing box packing rotation slippage, rotating ring 11 seals wing 14 and stationary ring 12 and seals wing 13 and directly contact with stuffing box packing 17, forms micro-interference fit state, makes seal operation state in the critical contact sealing state between contact sealing and non-contact sealing.Rotating ring 11 is Spielpassung with between centers, and the axial float of axle system can not drive rotating ring 11 play vertically, prevents from cutting off stuffing box packing 17, rotating ring 11 and between centers seal with O ring.
A kind of apex combustion seal that the utility model provides, by sealing the taper of wing cross section, has improved sealing wing axial stiffness, seals wing and occur the phenomenon of being completely cured while preventing real machine operation.
Above-described embodiment is only explanation technical conceive of the present utility model and feature; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement etc., within all should being included in protection domain of the present utility model.
