Abstract

The invention discloses a double-ring structure for a ring-splicing type graphite seal. The double-ring structure comprises two single ring structures and a clamping plate. Each single ring structure is formed by splicing and enclosing a plurality of carbon ring sections, the splicing positions of two adjacent carbon ring sections are spliced through matched wedge blocks, and end gaps are reserved at the splicing positions. The outer diameter of each single ring is further sleeved with a spring. The two single ring structures are respectively provided with a clamping groove, and the clamping plate is arranged in the clamping grooves and fixedly connects the two single ring structures side by side. By means of the double-ring structure for the ring-splicing type graphite seal, a reasonable matching gap between the inner diameter of a carbon ring and a shaft or a shaft sleeve still can be maintained after the carbon ring is abraded, it is further ensured that a carbon ring connector is not easily damaged in the conveying and installing process, and a good seal effect is kept.

Description

A kind of twin nuclei of spelling ring type graphite grazing
Technical field
The invention belongs to sealing configuration technical field, be specifically related to a kind of twin nuclei of spelling ring type graphite grazing.
Background technique
For integrated type carbon ring seal, in the time of real-world operation, transmission shaft or axle sleeve contact with carbocyclic ring, and after work a period of time, carbocyclic ring internal diameter certainly will have certain wearing and tearing.Once there is this situation, the matching gap of carbocyclic ring and axle or axle sleeve can increase gradually, affects sealing effect.
The distinguish carbocyclic ring of tradition carbon ring seal has straight degree of lip-rounding formula and angular cut form, and seal ring is cut into multi-clove type, is mainly for easy for installation.Straight mouthful of traditional carbocyclic ring is after wearing and tearing, under acting force of the spring, although can move inward, but because otch is right angle, and do not leave end gap, move past in journey interior, adjacent carbocyclic ring right angle mutually top touches, and cannot keep suitable, unified gap with axle or axle sleeve, thereby affect sealing effect; Although angular cut carbocyclic ring can address the above problem, if carbocyclic ring radial thickness size is little, the as easy as rolling off a log damage in transport and installation process of the angular cut end of carbocyclic ring, has increased maintenance cost.
Summary of the invention
For the defect existing in prior art and technical problem, the invention provides a kind of twin nuclei of spelling ring type graphite grazing, it both can still can keep the reasonable coordination gap between carbocyclic ring internal diameter and axle or axle sleeve after carbocyclic ring wearing and tearing, can ensure that again carbocyclic ring joint is not easy to damage in transport and installation process, keep good sealing effect.
For solving the problems of the technologies described above, the present invention has adopted following technological scheme: a kind of twin nuclei of spelling ring type graphite grazing, comprise two single ring architectures and clamp, described single ring architecture is surrounded by the splicing of multistage carbocyclic ring lobe, the stitching portion of adjacent two sections of carbocyclic ring lobes is the voussoir splicing of coupling, and end gap is left in stitching portion; The external diameter of described monocycle also overlaps spring; Two single ring architectures are respectively equipped with draw-in groove, and described clamp is located in draw-in groove and two single ring architectures are connected and fixed side by side.
As preferably, the two ends of described carbocyclic ring lobe are arc-shaped joint.
Further, the end gap on described two single ring architectures is for shifting to install.
Beneficial effect: with respect to prior art, the present invention is by whole carbocyclic ring is cut into multistage, and the joint of every section of carbocyclic ring lobe is arc-shaped joint, between two sections of carbocyclic ring lobes, closely, and joint is not fragile in transportation process in contact.Install simple, cost-saving, seal ring is installed rear every two sections of joints and is left certain end gap, make carbocyclic ring after wearing and tearing, each section of adjacent carbocyclic ring do not interfere with each other and radially inwardly slippage press close to axle or axle sleeve, keep rational matching gap between carbocyclic ring and axle or axle sleeve, the twice monocycle joint end gap of last twin nuclei, not on same straight line, makes sealing effect better.In the time of seal failure, only need to change seal ring, it is convenient to change.
Brief description of the drawings
Fig. 1 is the structural representation of twin nuclei of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the fractionation structural representation of single ring architecture of the present invention.
In figure: 1-carbocyclic ring lobe, 2-clamp, 3-spring, 4-joint end gap, 5-arc-shaped joint, 6-curve bath, 7-draw-in groove.
Embodiment
Below in conjunction with accompanying drawing and with specific embodiment, further illustrate the present invention.Should understand these embodiments and only be not used in and limit the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the amendment of the various equivalent form of values of the present invention.
As shown in Figures 1 to 3, a kind of twin nuclei of spelling ring type graphite grazing, this twin nuclei is made up of twice single ring architecture and clamp 3, and twice single ring architecture is made up of the spring 5 of four sections of carbocyclic ring lobes 1 and excircle respectively.Every section of carbocyclic ring lobe two ends are respectively equipped with arc-shaped joint 5 and curve bath 6, and when splicing, arc-shaped joint is deeply adjacent in curve bath.On these four sections of carbocyclic ring lobes 1, there is one section with draw-in groove 7, the difference of twice single ring architecture is the position difference of draw-in groove 7, adjust the joint end gap 4 between every two sections of carbocyclic ring lobes, and ensure that the joint end gap 4 of twice single ring architecture is not on same straight line, twice single ring architecture is all radially pressed close to through the tightening force effect of spring 3.Finally by clamp 2, twice single ring architecture is fixed, formed a twin nuclei of spelling ring type graphite grazing.
Whole carbocyclic ring is divided into four sections by four sections of carbocyclic ring lobes, in actual design process, also can be divided into three sections or more according to the whole carbocyclic ring of large young pathbreaker of axle or axle sleeve diameter.
In actual working procedure, once carbocyclic ring internal diameter circumference and axle or axle sleeve wear and tear, rely on the tightening force of carbocyclic ring outer peripheral surface upper spring 3, carbocyclic ring lobe 1 is radially tightened up, owing to all leaving certain joint end gap 4 in the middle of every two sections of carbocyclic ring lobes, thereby the carbocyclic ring after making to tighten up still matches with axle or axle sleeve, and basic identical with former carbocyclic ring internal diameter, keep original matching gap, reached good sealing effect.In the time that joint end gap 4 is reduced to a certain degree, just must change a whole set of single ring architecture.
