Abstract
The utility model discloses a shockproof strip fixing annular clamp for a steam generator in a nuclear power plant, which comprises a middle section, a first connecting piece and a second connecting piece, wherein two ends of the middle section are connected with the first connecting piece and a circular arc transition section respectively, the round angle radius R is less than or equal to 15mm, the middle section is mutually vertical to the first connecting piece and the second connecting piece, and electroplated chromium layers are coated on the middle section and the circular arc transition section. The thickness of each electroplated chromium layer is 25 mu m-50 mu m. The shockproof strip fixing annular clamp for the steam generator in the nuclear power plant has the advantages of being easy to form, simple in structure, low in cost, and the like, and can be used for replacing imported products.
Description
Technical field
The utility model relates to a kind of retainer ring card, or rather, is that a kind of nuclear power station steam generator that is applied in is with shockproof retainer ring card.
Background technology
Energy industry is the basis of national economy, be the important step of restriction national economy sustained and rapid development, along with development and national economy, people are more and more higher to living standard and environmental protection requirement, therefore, greatly develop the dominant direction that the nuclear power cause has become current energy development.It is conspicuous that nuclear power is compared its advantage with thermal power generation and other new forms of energy.Steam generator is the hinge of pressurized-water reactor nuclear power plant one loop and secondary circuit, it is the barrier of cutting apart the medium of a loop and secondary circuit, it is one of nuclear power station key equipment, also be one of the maximum equipment that breaks down in the nuclear power station device, the service behaviour of steam generator and security reliability are vital for the safe and stable operation of whole yarn system.A nuclear power station need be provided with several steam generators, includes ten hundreds of heat-transfer pipes, and the high-temperature setting-out flows in tube bank, supplying with water flows with vertical direction along pipe, be heated simultaneously, be vaporized then, steam enters the steam turbine generating, can cause vibrations with these pipe fluid in contact, break because of vibrations can cause damaged tubular, directly cause steam generator and damage, change a steam generator and need 200,000,000 dollars of left and right sides expenses, need the shutdown some months, cause great economic loss.For effectively preventing the pipe vibrations, shockproof retainer ring card is set the nuclear plant safety reliability service is played key effect.
Heat-transfer pipe is a U type pipe, it is the critical piece of nuclear power station steam generator, the tube bank of steam generator comprises many heat-transfer pipes in a row, shockproof of configuration comes support tube between the adjacent row of pipe, reach shockproof effect, for fixing shockproof, also need to be provided with the retainer ring card between shockproof and shockproof.
Summary of the invention
The utility model mainly is to solve the existing in prior technology problem, thereby a kind of easy-formation is provided, and is simple in structure, the retainer ring card that cost is low.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: one
Plant nuclear power station steam generator with shockproof retainer ring card, comprise interlude, first connector and second connector, described interlude and arc transition section are coated with electrodeposited chromium layers.
The thickness of described electrodeposited chromium layers is between 25 μ m-50 μ m.
The thickness of described electrodeposited chromium layers is 30 μ m.
The two ends of described interlude are connected with described arc transition section respectively with second connector with described first connector, and radius of corner R is smaller or equal to 15 ㎜, and as preferably, described radius of corner R equals 13 ㎜.
The described interlude and first connector and second connector are orthogonal.
The described interlude and first connector and second connector are structure as a whole.
The utility model has the advantages that easy-formation, simple in structure, characteristics such as cost is low.
Description of drawings
Fig. 1 is a perspective view of the present utility model.
Fig. 2 is a front view of the present utility model.
Among the figure: 1, interlude 2, first connector 3, second connector.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail, thereby protection scope of the present invention are made more explicit defining so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that.
The purpose of this utility model provides a kind of easy-formation, and is simple in structure, and the low nuclear power station steam generator of cost is with shockproof retainer ring card.
As shown in Figure 1 and Figure 2, a kind of nuclear power station steam generator is with shockproof retainer ring card, described nuclear power station steam generator is refined to the regulation finished size with shockproof retainer ring card material process, utilize the particular manufacturing craft precise punch forming, the electrodeposited chromium processing is carried out to interlude 1 and arc transition section in treated polishing back, surface, the thickness of chromium coating is 30 μ m, the two ends of described interlude are connected with described arc transition section respectively with second connector with described first connector, and radius of corner R is 13 ㎜.The described interlude 1 and first connecting portion 2, second connecting portion 3 are orthogonal.
The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in technical scope disclosed in the utility model; any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.
