Abstract
The utility model discloses a split self compensating carbocycle, it is including ring sum extension spring in three minute, three divide ring end to end to constitute the ring, it is three all be provided with the extension spring groove on the excircle circumference of branch ring, the extension spring is installed the extension spring inslot, and it is fixed three divide the position between the ring, it is three divide the ring to fix the suit epaxial through upper cover and lower cover. The utility model relates to a split self compensating carbocycle makes the inseparable laminating of three branch ring together through the extension spring, the during operation because mediate coupling touches and leads to circle uniform wear in the carbocycle in the carbocycle, make the carbocycle under the effort of extension spring in the circle size remain unchanged always to play long -term sealed effect.
Description
Technical field
This utility model relates to a kind of carbocyclic ring, particularly relates to a kind of point of lobe self compensation carbocyclic ring.
Background technology
Development along with chemical industry, the application of aerator, compressor and turbine is more and more extensive, applying working condition is also all the more complicated, uses the requirement that aerator is sealed vent flow by producer also more and more higher simultaneously, and traditional carbon ring sealing structure form can not meet Part load requirement.Because, when in carbon ring seal, the operation principle of carbocyclic ring is to utilize axle (axle sleeve) high-speed cruising, the fluid dynamic of generation makes carbocyclic ring be in half suspended state, but can cause that carbocyclic ring produces abrasion with axle (axle sleeve) contact site after long-time use；And the carbocyclic ring in traditional structure does not have self-compensating performance upon wear, cause carbon ring seal leakage rate to be continuously increased, cause seal failure.
Utility model content
The purpose of this utility model is that provides a kind of point of lobe self compensation carbocyclic ring to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of point lobe self compensation carbocyclic ring, including three points of rings and extension spring, point end to end composition annulus of ring described in three, the cylindrical circumference of point ring described in three is provided with extension spring groove, described extension spring is arranged in described extension spring groove, and fix the position divided described in three between ring, described in three, a point ring is fixedly set on axle by upper cover and lower cover.
Specifically, it is provided with Anti-rotary block between described point of ring and described upper cover and described lower cover.
Preferably, the joint face place of point ring described in adjacent two is provided with pairing mark.
The beneficial effects of the utility model are in that:
This utility model one divides lobe self compensation carbocyclic ring to make three points of rings fit together closely by extension spring, during work, causing carbocyclic ring inner circle uniform wear owing to carbocyclic ring inner circle contacts with axle, making carbocyclic ring inner circle size be always maintained at constant under the active force of extension spring, thus playing long-term sealing effectiveness.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of a kind of point of lobe self compensation carbocyclic ring described in the utility model；
Fig. 2 is the structural representation of a kind of point of lobe self compensation carbocyclic ring described in the utility model；
Fig. 3 is the sectional view of a kind of point of lobe self compensation carbocyclic ring described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, Figure 2 and Figure 3, this utility model one divides lobe self compensation carbocyclic ring, including three points of rings 1 and extension spring 2, three points of end to end composition annulus of ring 1, the cylindrical circumference of three points of rings 1 is provided with extension spring groove 4, and extension spring 2 is arranged in extension spring groove 4, and fix the position between three points of rings 1, three points of rings 1 are fixedly set on axle by upper cover and lower cover, divide and are provided with Anti-rotary block 3 between ring 1 and upper cover and lower cover, and the joint face place of adjacent two points of rings 1 is provided with pairing mark 5.
The operation principle of a kind of point of lobe self compensation carbocyclic ring of this utility model is as follows:
Gradually fitted tightly by distinctive fit system by three points of rings 1, cooperation place (i.e. joint face place) of each point of ring 1 by peculiar technique to reach close-fitting effect, carbocyclic ring cylindrical circumference is installed extension spring 2, makes three points of rings 1 fit together closely.During work, causing carbocyclic ring inner circle uniform wear owing to carbocyclic ring inner circle contacts with axle sleeve, making carbocyclic ring inner circle size be always maintained at constant under the active force of extension spring 2, thus playing long-term sealing effectiveness.
Additionally, three points of rings 1 in this device are processed by an integrally-built carbocyclic ring, carry out a point lobe after the aperture position of each point of ring 1 performs pairing mark 5.Thus when mounted, carbocyclic ring can fit tightly, and the depth of parallelism of each plane can be guaranteed.Such carbocyclic ring structure because of end face unbalance stress, will not cause the situation that carbocyclic ring end face is bad with the laminating of gland end face, therefore the carbocyclic ring of this structure can reach the sealing effectiveness of original carbocyclic ring equally when carbon ring seal runs.
In use, organize carbocyclic ring by installing more, and the carbon ring seal of different structural arrangement form compositions, play different sealing effectiveness.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, every technology deformation made according to the technical solution of the utility model, each falls within protection domain of the present utility model.
