Abstract
The utility model discloses a novel steam seal which comprises a steam seal body (1) and steam seal teeth (2), and is characterized in that the steam seal body (1) adopts a cylindrical structure; the steam seal teeth are uniformly arranged on the inner wall of the steam seal body (1); a strengthening structure is arranged at the joint of each of the steam seal teeth and the steam seal body (1); a layer of anti-corrosion material (3) is arranged on each of the surfaces of the steam seal teeth (2) and the inner wall of the steam seal body (1). The utility model provides a novel steam seal which is simple in structure, good in fracture resistance and rust prevention, and long in service through the combination and innovation of the steam seal body, the steam seal teeth and the anti-corrosion materials.
Description
Technical field
The utility model relates to a kind of packing, relates in particular a kind of Novel steam seal of long service life.
Background technique
Packing is to be installed between the dynamic and static part of steam turbine, reduces or prevents the device that steam leaks and inlet side air bleeds.Because gland seal structure is unreasonable, there is the problem that easily ruptures and get rusty easily, this all affects the working life of packing.And general gland seal structure of the prior art does not effectively address the above problem.Chinese patent notice of authorization CN 201991573 U for example, at on 09 28th, 2011 notice of authorization day, the name of innovation and creation is called how short tooth convergent-divergent type packing, this Patent Case discloses a kind of gland seal structure, by the structure innovation of packing segmental arc, spring and length tooth, this gland seal structure has been realized the feature that can regulate labyrinth clearance, but the crown thickness of this Patent Case length tooth is little, structure is thin, has the easily problem of fracture.For another example Chinese patent notice of authorization CN 203081512 U, at on 07 24th, 2013 notice of authorization day, the name of innovation and creation is called sealing gland after steam turbine, this patent discloses a kind of sealing gland, by the combined innovation of three seal rings, reduced the wearing and tearing of packing, extend the working life of packing, but the sealing gland of this Patent Case lacks rust preventing, exist get rusty easily problem.The utility model, by the combined innovation of packing main body, gland sealing gear and anticorrosive, provides a kind of simple in structure, and anti-fracture ability and antirust ability are good, the Novel steam seal of long service life.
Summary of the invention
The utility model solves general gland seal structure in prior art does not have effectively to solve the problem that gland sealing gear easily ruptures and gets rusty, a kind of Novel steam seal is provided, by the combined innovation of packing main body, gland sealing gear and anticorrosive, realizing this Novel steam seal has simple in structure, anti-fracture ability and antirust ability are good, the feature of long service life.
In order to solve the technical problem of above-mentioned existence, the utility model is taked following technical proposals: a kind of Novel steam seal, comprise packing main body and gland sealing gear, it is characterized in that, described packing main body is Cylindrical object structure, described gland sealing gear is evenly provided with the inwall in packing main body, and the joint of gland sealing gear and packing main body is provided with reinforcement structure, and the inwall of the surface of described gland sealing gear and packing main body is equipped with one deck anticorrosive.
The packing main body of Cylindrical object structure, simple in structure, easy to process; Strengthen structure, strengthen the join strength of packing main body and gland sealing gear, reduce the stress of packing main body and gland sealing gear joint and concentrate probability, prevent gland sealing gear fracture, extend the working life of this packing; Anticorrosive, prevents that the inwall of packing main body and gland sealing gear from getting rusty, and extends the working life of this packing.Gland seal structure of the present utility model is compared with two documents, and anti-fracture ability and antirust ability are better, the longer service life of packing.
Preferably, described reinforcement structure is arc angling structure.Arc angling, smooth surface, the joint of packing main body and gland sealing gear, without dead angle, is reduced the stress of packing main body and gland sealing gear joint and is concentrated probability, prevents gland sealing gear fracture.
Preferably, described reinforcement structure is triangular chamfered structure.Triangular chamfered, simple in structure, easy to process.
Preferably, the crown of described gland sealing gear is provided with rounding.Rounding, simple in structure, reduce the stress of gland sealing gear crown and concentrate probability, prevent crown fracture, extend the working life of gland sealing gear.
Preferably, described anticorrosive is ceramic composite film.Ceramic composite film, both corrosion protections, high temperature resistant again.
Preferably, the height of described gland sealing gear is 1.5 times of its thickness.Suitable height and thickness proportion, the intensity of increase gland sealing gear, the anti-fracture ability of raising gland sealing gear.
Owing to taking above-mentioned technological scheme, a kind of Novel steam seal that the utility model provides has such beneficial effect: by the combined innovation of packing main body, gland sealing gear and anticorrosive, provide a kind of simple in structure, anti-fracture ability and antirust ability are good, the Novel steam seal of long service life.
