Abstract
The utility model provides a kind of adjustable comb tooth sealing structure, comprise labyrinth seal ring body, labyrinth seal ring body is provided with multiple segmental arc, the two ends place of each segmental arc is respectively equipped with the first little convex surface and the second little convex surface, described first little convex surface is formed with the adjustment convex of the radial clearance for adjusting sealing surface.The device that the utility model provides overcomes the deficiencies in the prior art, overhaul and the sealing of mounting broach sealing configuration time, can by adjustment convex is carried out accurate, simple and direct, process fast, thus make the radial clearance of sealing surface reach accurate usage requirement.
Description
Technical field
The utility model relates to a kind of labyrinth seal with adjustable function sealed for vapour (gas), belongs to turbomachinery technical field of sealing technology.
Background technique
Fig. 1 and Figure 2 shows that traditional comb tooth sealing structure schematic diagram, traditional comb tooth sealing structure comprises labyrinth seal ring body, and labyrinth seal ring body has multiple segmental arc, is respectively equipped with the first little convex surface 1 and the second little convex surface 3 at the two ends place of each segmental arc.In installation and maintenance process, as found, sealing surface 4 can not reach usage requirement, then need to process little convex surface, workload is large, if and process uneven, to finally cause sealing surface can not reach usage requirement accurately, thus cause the leakage loss of medium to increase and affect the Security used.
Model utility content
The technical problems to be solved in the utility model is to provide one can the comb tooth sealing structure that seals of accurate, simple and direct, rapid adjustment vapour (gas).
In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide a kind of adjustable comb-shaped sealing configuration, comprise labyrinth seal ring body, labyrinth seal ring body is provided with multiple segmental arc, the two ends place of each segmental arc is respectively equipped with the first little convex surface and the second little convex surface, it is characterized in that: the adjustment convex described first little convex surface and the second little convex surface being formed with the radial clearance for adjusting sealing surface.
The device that the utility model provides overcomes the deficiencies in the prior art, overhaul and the sealing of mounting broach sealing configuration time, can by adjustment convex is carried out accurate, simple and direct, process fast, thus make the radial clearance of sealing surface reach accurate usage requirement.
Accompanying drawing explanation
Fig. 1 is traditional comb tooth sealing structure schematic diagram;
Fig. 2 is A-A sectional view in Fig. 1;
The adjustable comb-shaped sealed structural representation that Fig. 3 provides for the utility model;
Fig. 4 is B-B sectional view in Fig. 3.
Embodiment
For making the utility model become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
As shown in Figure 3 and Figure 4, a kind of adjustable comb tooth sealing structure that the utility model provides comprises labyrinth seal ring body, labyrinth seal ring body has multiple segmental arc, be respectively equipped with the first little convex surface 1 and the second little convex surface 3 at the two ends place of each segmental arc, the first little convex surface 1 is formed with the adjustment convex 2 sealing radial clearance for adjusting vapour (gas).
Notice that the remaining thickness of little back of the body arc can not be too little, otherwise the original effect of little back of the body arc can be lost, reduce safety coefficient.Note the height of adjustment convex relative to little back of the body arc, highly whether the workload of suitable decision installation and repairing and Security when using.
When overhauling and install, can, by the process to adjustment convex, the radial clearance of sealing surface be made to reach accurate usage requirement.Adjust simple and direct, quick, workload is little, and adjustment result is accurate.
