Description
Technical field
The utility model relates to a kind of link, particularly relates to a kind of steam turbine cover piece nut.
Background technique
Steam turbine is the rotary power machinery transformation of energy of steam being become mechanical work.Also known as steam turbine.Main prime mover being used as generating, also can the various pump of Direct driver, blower fan, compressor and propeller for vessels etc.The steam discharge of steam turbine or intermediate extraction can also be utilized to meet and to produce and heat supply needs in life.Steam turbine is the external combustion rotary machine that steam thermal energy can be converted into mechanical work, after entering steam turbine, successively through nozzle and the movable vane of series of annular configuration, is the mechanical energy that turbine rotor rotates by the thermal energy of steam from the steam of boiler.Steam, in steam turbine, carries out transformation of energy by different way, just constitutes the steam turbine of different operating principle.Steam turbine works usually under High Temperature High Pressure and high-revolving condition, it is a kind of comparatively accurate heavy machinery, generally must form complete sets of equipment, cooperation work together with boiler (or other steam generators), generator (or other are by driving device) and vapour condenser, heater, pump etc.But steam turbine cover piece is not easy locking when assembling, affects steam turbine follow-up work, so there is deficiency.
In sum, for the defect of prior art, need steam turbine cover piece nut especially, to solve the deficiencies in the prior art.
Model utility content
For in prior art to the deficiency that steam turbine nut in use exists, and bring very large inconvenience in the work of reality, the utility model proposes steam turbine cover piece nut, structure is simple, modern design, is convenient to lock steam turbine cover piece, addresses the deficiencies of the prior art.
To achieve these goals, the utility model realizes by the following technical solutions:
Steam turbine cover piece nut, comprise nut, the material that nut adopts is alloyed steel, the internal surface of nut offers internal thread, the outer surface of nut is provided with stiffening rib, and the surrounding of stiffening rib is provided with groove, and the below of nut is provided with balanced support plate, one end of balanced support plate is provided with outside thread, and the other end of balanced support plate is provided with draw ring.
Further, detachable connection is adopted between described balanced support plate and nut.
Further, the diameter of described nut is 30mm, and the length of internal thread is identical with nut length.
The beneficial effects of the utility model are: this product structure is simple, easy to make, conveniently nut is used above steam turbine cover piece, not only facilitate the fastening of case, and fixed performance is excellent, contraposition is accurate, the field used is wide, and practicability is excellent, novel in design, be a kind of well innovation scheme, have very much marketing prospect.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the utility model steam turbine cover piece nut structure schematic diagram.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
See Fig. 1, steam turbine cover piece nut, comprise nut 100, the material that nut 100 adopts is alloyed steel, the internal surface of nut 100 offers internal thread 110, the outer surface of nut 100 is provided with stiffening rib 120, and the surrounding of stiffening rib 120 is provided with groove 130, and the below of nut 100 is provided with balanced support plate 140, one end of balanced support plate 140 is provided with outside thread, and the other end of balanced support plate 140 is provided with draw ring 150.
Further, detachable connection is adopted between described balanced support plate 140 and nut 100.The diameter of nut 100 is 30mm, and the length of internal thread 110 is identical with nut 100 length.
The utility model is effective is: structure is simple, easy to make, conveniently nut is used above steam turbine cover piece, not only facilitate the fastening of case, and fixed performance is excellent, contraposition is accurate, the field used is wide, and practicability is excellent, novel in design, be a kind of well innovation scheme, have very much marketing prospect.
