Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As shown in Figure 1, this two flap-type carbon ring seal, comprises two groups of half carbocyclic rings 2 stacked gradually, halfwave plate spring 3 and half mounting plate 4; Half carbocyclic ring 2, halfwave plate spring 3 and half mounting plate 4 are semicircular configuration, and two and half carbocyclic ring 2, two halfwave plate springs 3 and two and half mounting plates 4 respectively split are a complete carbocyclic ring, a complete wave plate spring and a complete mounting plate.
Half carbocyclic ring 2 and half mounting plate 4 outer peripheral surface are provided with banding extension spring mounting groove 10, and banding extension spring 5 is arranged in banding extension spring mounting groove 10, the carbocyclic ring complete for banding and complete mounting plate.Banding extension spring 5 structure as shown in Figures 2 and 3.
Wherein one group of half carbocyclic ring 2 stacked together and half mounting plate 4 outer ledge are provided with positioning block slot 11, are provided with the positioning block 6 for preventing half carbocyclic ring 2 and half mounting plate 4 from rotating in positioning block slot 11.Positioning block 6 structure as shown in Figure 4.
Half mounting plate 4 is provided with the half carbocyclic ring mounting groove 4a for guiding half carbocyclic ring 2 in axial direction bidirectional-movement.
Upper cavity 7 and lower chamber 1 are provided with Sealing mounting groove 12, and complete carbocyclic ring, complete wave plate spring and complete mounting plate are installed in Sealing mounting groove 12.
Further, upper cavity 7 and lower chamber 1 are provided with two Sealing mounting grooves 12, two and overlap complete carbocyclic ring, complete wave plate spring and complete mounting plate and to put in order identical being arranged on respectively in two Sealing mounting grooves 12.
Upper cavity 7 and lower chamber 1 are mutually permanently connected by screw 8.
Upper cavity 7 is provided with the stop pin 9 preventing this two flap-type carbon ring seal from rotating.
Upper cavity 7 and lower chamber 1 outer side wall are provided with seal ring.
As shown in Figure 1, half carbocyclic ring 2 and halfwave plate spring 3, half mounting plate consist of parts when mounted, the left-half of the basic module of the carbon ring seal that two these parts are formed jointly and right half part.Halfwave plate spring 3 by half carbocyclic ring 2 pre-pressing on lower chamber 1, under the effect of pressure medium, both fit tightly, form sealing surface, prevent from forming gap between half carbocyclic ring and lower chamber, fit tightly under banding extension spring 5 contraction between two lobe half carbocyclic rings 2, the carbocyclic ring that two and half carbocyclic rings 2 are formed can shrink, and compensates carbocyclic ring wearing and tearing, ensures that medium can only by one, the gap between carbocyclic ring and machine spindle leakage way.There is micro-gap between carbocyclic ring and machine spindle, gap has reducing pressure by regulating flow effect.Due to reducing pressure by regulating flow effect, a small amount of medium is by gap, and pressure medium reduces.Medium after pressure reduces blows to bearing, prevents bearing oil from entering carbon ring seal.
