Abstract
The utility model provides a kind of adjustable composite teeth sealing configuration, comprise composite teeth seal ring body, composite teeth seal ring body adds axial tooth by the admission face of the straight-tooth at serrate-type steam seal and forms, composite teeth seal ring body is provided with multiple segmental arc, the two ends place of each segmental arc is provided with little back of the body arc, is provided with the adjustment convex for adjusting seal clearance below little back of the body arc.During use, can, by the process to adjustment convex, the radial clearance of sealing surface be made to reach accurate usage requirement.The device that the utility model provides overcomes the deficiencies in the prior art, easy to process, and cost is low, and adjust seal clearance value when being convenient to in-site installation and maintenance, adjust simple and direct, quick, workload is little, and adjustment result is accurate.
Description
Technical field
The utility model relates to a kind of adjustable composite teeth sealing configuration sealed for vapour (gas), belongs to turbomachinery technical field of sealing technology.
Background technique
The composite teeth sealing configuration that tradition vapour (gas) seals, as depicted in figs. 1 and 2, comprise composite teeth seal ring body, composite teeth seal ring body adds axial tooth by the admission face of the straight-tooth at serrate-type steam seal and forms, composite teeth seal ring body has multiple segmental arc, is respectively equipped with the first little convex surface 3 and the second little convex surface 4 at the two ends place of each segmental arc.In installation and maintenance process, as found, the sealing surface 5 of packing parent ring can not reach usage requirement, then by processing little convex surface, workload is large, and process uneven, finally cause sealing surface 5 accurately can not reach usage requirement, thus cause the leakage loss of medium to increase, and the Security that impact uses.
Model utility content
The technical problems to be solved in the utility model is to provide one can the adjustable composite teeth sealing configuration 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 composite teeth sealing configuration, comprise composite teeth seal ring body, composite teeth seal ring body adds axial tooth by the admission face of the straight-tooth at serrate-type steam seal and forms, composite teeth seal ring body is provided with multiple segmental arc, the two ends place of each segmental arc is provided with little back of the body arc, it is characterized in that: be provided with the adjustment convex for adjusting seal clearance below described little back of the body arc.
When the adjustable composite teeth sealing configuration that the utility model provides uses, can, by the process to adjustment convex, the radial clearance of sealing surface be made to reach accurate usage requirement.
The device that the utility model provides overcomes the deficiencies in the prior art, easy to process, and cost is low, and adjust seal clearance value when being convenient to in-site installation and maintenance, adjust simple and direct, quick, workload is little, and adjustment result is accurate.
Accompanying drawing explanation
Fig. 1 is traditional adjustable composite teeth sealed structural representation;
Fig. 2 is A-A sectional view in Fig. 1;
The adjustable composite teeth 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.
Composition graphs 3 and Fig. 4, the adjustable composite teeth sealing configuration that the utility model provides, comprise composite teeth seal ring body, composite teeth seal ring body adds axial tooth by the admission face of the straight-tooth at serrate-type steam seal and forms, composite teeth seal ring body is provided with multiple segmental arc, and the two ends place of each segmental arc is provided with little back of the body arc 1, processes little back of the body arc 1, change the thickness of little back of the body arc, form two and can be used for adjusting the adjustment convex 2 that vapour (gas) seals radial clearance.
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 2, the radial clearance of sealing surface 5 be made to reach accurate usage requirement.Adjust simple and direct, quick, workload is little, and adjustment result is accurate.
The adjustable composite teeth sealing configuration that the utility model provides is applicable to the composite teeth sealing that structure made a concession by seen various band at present, and design easy to process, cost is low, the gap width of adjustable composite teeth sealing when being convenient to in-site installation and overhauling, shorten the installation and repairing time, make adjustable composite teeth seal clearance value more accurate, to such an extent as to reach energy-saving and cost-reducing object.
