Abstract
The utility model provides an adjustable brush-shaped honeycomb type seal structure comprising a segmental arc. Two ends of segmental arc are respectively provided with a small convex surface . A sealing surface is arranged on two sides of the bottom of the segmental arc; and the lower part of the small convex surface is provided with adjusting bosses. The adjustable brush-shaped honeycomb type seal structure overcomes deficiencies of the prior art and can accurately, fast and simply process the adjusting bosses, so that a precise operating requirement for radial clearance of the sealing surface can be met, thereby improving use safety.
Description
Technical field
The utility model relates to a kind of brush honeycomb type sealing structure with adjustable function, is mainly used in vapour (gas) sealing, belongs to the turbomachinery technical field of sealing technology.
Background technique
At present, the brush honeycomb type sealing structure of existing vapour (gas) sealing, adjust workload large in maintenance and installation process, and it is very low to adjust precision.As depicted in figs. 1 and 2, in installation and maintenance process, as found, sealing surface 3 can not reach usage requirement, by the little convex surface 2 to segmental arc 1 two ends, processed, workload is large, and processes inhomogeneously, finally causes sealing surface 3 can not accurately reach usage requirement, thereby cause the leakage loss of medium to increase, and the Security of impact use.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of brush honeycomb type sealing structure that can adjust accurate, simple and direct, rapidly vapour (gas) sealing.
In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide a kind of brush honeycomb type sealing structure with adjustable function, comprise segmental arc, the segmental arc two ends are provided with little convex surface, sealing surface is located at the segmental arc two bottom sides, it is characterized in that: described little convex surface bottom is provided with the adjustment convex.
The utility model provides a kind of brush honeycomb type sealing structure with adjustable function is in maintenance with while installing, can carry out accurate, simple and direct, processing fast to adjusting convex, thereby the radial clearance that makes sealing surface reaches accurate usage requirement, guarantee the Security of using.
The device that the utility model provides has overcome the deficiencies in the prior art, can be accurate, simple and direct, to adjusting convex, processed rapidly, thus make the radial clearance of sealing surface reach accurate usage requirement, guarantee the Security of using.
The accompanying drawing explanation
Fig. 1 is former common brush honeycomb type sealing structure schematic diagram;
The A-A sectional view that Fig. 2 is Fig. 1;
A kind of brush honeycomb type sealing structure schematic diagram with adjustable function that Fig. 3 provides for the utility model;
The B-B sectional view that Fig. 4 is Fig. 2.
Embodiment
For the utility model is become apparent, hereby with a preferred embodiment, and coordinate accompanying drawing to be described in detail below.
A kind of brush honeycomb type sealing structure schematic diagram with adjustable function that Fig. 3 provides for the utility model, described a kind of brush honeycomb type sealing structure with adjustable function is that little convex surface 2 bottoms to former common brush honeycomb type sealing structure segmental arc 1 two ends are processed, change the thickness of little convex surface 2, as shown in Figure 2, form two adjustment convexes 4 that can be used for adjusting vapour (gas) sealing radial clearance.
Add man-hour, note the reservation thickness of little convex surface, can not be too little, otherwise can lose the original effect of little convex surface, reduce safety coefficient.Note adjusting the height of convex with respect to little convex surface, the Security when workload highly whether suitable decision is installed, overhauled and use.
The utility model provides a kind of brush honeycomb type sealing structure with adjustable function is in maintenance with while installing, can carry out accurate, simple and direct, processing fast to adjusting convex 4, thereby the radial clearance that makes sealing surface 3 reaches accurate usage requirement, guarantee the Security of using.
