Abstract
The utility model provides an adjustable ferrite brush type honeycomb sealing structure which comprises a ferrite brush type honeycomb sealing ring body, wherein the ferrite brush type honeycomb sealing ring body is provided with a plurality of arc sections; and a first small back arc surface and a second small back arc surface are respectively arranged at the two ends of each arc section. The adjustable ferrite brush type honeycomb sealing structure is characterized in that an adjusting bulge is formed on each first small back arc surface. With the adoption of the utility model, when the sealing for the steam (gas) ferrite brush type honeycomb sealing structure is overhauled and installed, the adjusting bulge can be accurately, simply and quickly processed, so that the radial gap of a sealing surface can meet the accurate use requirements.
Description
Technical field
The utility model relates to the brush honeycomb seal structure of ferrite that is used for vapour (gas) sealing in a kind of turbomachinery.
Background technique
As shown in Figure 1, be existing ferrite brush seal structure, comprise the brush honeycomb seal ring body of ferrite, the brush honeycomb seal ring body of ferrite has a plurality of segmental arcs, is provided with the first little convex surface 1 and the second little convex surface 3 respectively at the place, two ends of each segmental arc.In installation and maintenance process; As find that sealing surface can not reach usage requirement; Then need handle little convex surface, workload is big, and if handle inhomogeneous; To finally cause sealing surface can not reach usage requirement accurately, thereby cause the Security that leakage loss increases and influence is used of medium.
Summary of the invention
The purpose of the utility model provide a kind of can be accurate, simple and direct, the brush honeycomb seal structure of ferrite of rapid adjustment vapour (gas) sealing.
In order to achieve the above object; The technological scheme of the utility model has provided a kind of brush honeycomb seal structure of ferrite of adjusting; Comprise the brush honeycomb seal ring body of ferrite; The brush honeycomb seal ring body of ferrite has a plurality of segmental arcs, is provided with the first little convex surface and the second little convex surface respectively at the place, two ends of each segmental arc, it is characterized in that: on the first little convex surface, be formed with the adjustment convex.
After adopting the utility model, when maintenance and installation are used for the sealing of the brush honeycomb seal structure of vapour (gas) ferrite, can to the adjustment convex carry out accurate, simple and direct, handle fast, thereby make the radial clearance of sealing surface, reach accurate usage requirement.
Description of drawings
Fig. 1 is former ferrite brush seal structural representation;
A kind of structural representation of adjusting the brush honeycomb seal structure of ferrite that Fig. 2 provides for the utility model.
Embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 2; A kind of brush honeycomb seal structure of ferrite of adjusting that the utility model provides; Comprise the brush honeycomb seal ring body of ferrite; The brush honeycomb seal ring body of ferrite has a plurality of segmental arcs, is provided with the first little convex surface 1 and the second little convex surface 3 respectively at the place, two ends of each segmental arc, on the first little convex surface 1, is formed with adjustment convex 2.
Note the reservation thickness of little back of the body arc, can not be too little, otherwise can lose the original effect of little back of the body arc, reduce safety coefficient.Highly whether suitable attention adjustment at the height of convex 2 with respect to little back of the body arc, the Security the when workload of decision installation maintenance and use.
Claims (1)
1. can adjust the brush honeycomb seal structure of ferrite for one kind; Comprise the brush honeycomb seal ring body of ferrite; The brush honeycomb seal ring body of ferrite has a plurality of segmental arcs; Place, two ends in each segmental arc is provided with the first little convex surface (1) and the second little convex surface (3) respectively, it is characterized in that: on the first little convex surface (1), be formed with adjustment convex (2).
