Abstract
The utility model discloses a quake-proof strip for a novel nuclear power station steam generator. The quake-proof strip comprises a quake-proof strip body and end caps, wherein the quake-proof strip body has a U-shaped included angle, and each end cap penetrates through two ends of the quake-proof strip body to be pressed and fixed on the quake-proof strip body. Each end cap is fixed on the quake-proof strip body through a central press point, and first press points capable of preventing the end caps from sliding up and down are symmetrically arranged on the left side and the right side of each end of the quake-proof strip body. The quake-proof strip has the advantages of being simple to manufacture, high in safety and capable of effectively having the quake-proof effects and avoiding large economical loss.
Description
Technical field
The utility model relates to a kind of nucleus power station steam generator anti-vibration strip.
Background technology
AP1000 is the third generation million kilowatt advanced pressurized water reactor nuclear power generating sets of US Westinghouse company's exploitation.AP1000 is different from the security system that the main feature that two generations added CPR1000 compressed water reactor nuclear power unit is exactly " non-active "." non-active " design concept is exactly to utilize intrinsic hot-working hydraulic characteristic, simplify the design of security system, make nuclear power station guarantee that the measure of safety no longer relies on the operation of the active equipment such as pump, blower fan, thereby reduced significantly valve, pump, cable and the antidetonation factory building of safe level; Cancelled 1E level emergency diesel dynamo system; Reduced the active equipment of most of safe level; Reduced large material usage; System simplification makes design simplification, technology arrangement simplification, construction volume minimizing, operation and also corresponding minimizing of maintenance capacity.
Steam generator is the nuclear power station key equipment, also be one of the maximum equipment that breaks down in the nuclear power station device, its effect is that handle is passed to secondary circuit water by the heat of the cooling agent of reactor, and makes it to become steam, passes into the cylinder work done of steam turbine generator again.
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 arrange several steam generators, include ten hundreds of heat-transfer pipes, heat-transfer pipe is U-shaped pipe, it is the critical piece of nuclear power station steam generator, the high-temperature setting-out flows in tube bank, flow with vertical direction along pipe for feedwater, be heated simultaneously, then be vaporized, steam enters the steam turbine generating, the fluid that contacts with these pipes can cause vibrations, break because vibrations can cause damaged tubular, directly cause steam generator and damage, change a steam generator and need 200,000,000 dollars expenses, need the shutdown some months, cause great economic loss.
Break in order to prevent that effectively pipe from shaking, the configuration anti-vibration strip comes support tube between the adjacent row of pipe, anti-vibration strip is set the nuclear plant safety reliability service is played key effect.
The utility model content
A kind of nucleus power station steam generator anti-vibration strip that provides of the present utility model is made simple, reasonable in design and production cost is low, and more effectively the heat-transfer pipe of supported steam generator reaches shockproof purpose.
The utility model is achieved through the following technical solutions: a kind of nucleus power station steam generator anti-vibration strip, comprise anti-vibration strip and end cap, wherein said anti-vibration strip has U-shaped angle, and each described end cap passes from the two ends of described anti-vibration strip respectively and pressing is fixed on the described anti-vibration strip.
Wherein each described end cap be fixed on the described anti-vibration strip by the center pressure point and the left and right sides of the every end of described anti-vibration strip on all be symmetrically arranged with the first pressure point that prevents that end cap from sliding up and down.
The U-shaped angle of described anti-vibration strip be 10 ° 53 '.
The beneficial effects of the utility model are: make simple, the safe shockproof effect of more effectively opening, avoid causing huge economic loss.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Wherein 1-anti-vibration strip, 2-end cap, 3-center pressure point, 4-the first pressure point.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1: a kind of nucleus power station steam generator anti-vibration strip of the present embodiment, comprise that anti-vibration strip 1, end cap 2, wherein said anti-vibration strip 1 have U-shaped angle, described U-shaped angle be 10 ° 53 ', each described end cap 2 passes from the two ends of described anti-vibration strip 1 respectively and is fixed on the described anti-vibration strip 1 by center pressure point 3.
All be symmetrically arranged with the first pressure point 4 that prevents that end cap 2 from sliding up and down on the left and right sides of described anti-vibration strip 1 every end.
The beneficial effect of the present embodiment is: easily be shaped, safe and make simply, anti seismic efficiency is more remarkable.
