Description
Technical field
The present invention relates to nuclear power plant's main cooling system technical field, more particularly to a kind of voltage-stablizer internal structure.
Background technology
Voltage-stablizer is used in nuclear reactor primary Ioops, is the important composition device of nuclear power plant's main cooling system, in primary Ioops
When generation accident causes pressure rise or reduces, automatically adjust pressure to primary Ioops, so as to ensure the normal work of primary Ioops
Make.
Environment residing for the nuclear power plant of sea base is harsher with respect to continental rise nuclear power plant, outside in wind, wave and ocean current etc.
Under the influence of condition, carry nuclear power plant maritime floating platform or ship can run-off the straight, the motion such as rise and fall, wave.Now,
The water surface in nuclear power plant's voltage-stablizer occurs nonlinear sloshing phenomenon, in this case, the water slug voltage stabilizing in voltage-stablizer
Device chamber wall, different degrees of surge is caused to voltage-stablizer inwall.When surge than it is larger when, sloshing phenomenon is possible to
Directly jeopardize the structural intergrity of voltage-stablizer.Meanwhile, rocking caused surge can produce to the level measuring in voltage-stablizer
Raw significantly influence, when occurring sloshing phenomenon in voltage-stablizer, the water level of measurement is higher or lower than actual water level, in this feelings
Under condition, water level control system frequent movement is caused, it could even be possible to causing the false triggering of safety signal.In addition, working as sloshing phenomenon
When comparing violent, it is likely to occur exposed at the top of the heating rod in voltage-stablizer, causes heating rod in time to cool down and burn.Such as
The sloshing phenomenon that fruit can not effectively suppress in voltage-stablizer, the security of nuclear power plant, reliability and economy will all drop significantly
It is low.
To improve the security of nuclear power plant, reliability and economy, it is necessary to which providing a kind of can suppress sloshing phenomenon

Compared with prior art, the new structure of sloshing phenomenon has advantages below in present invention suppression voltage-stablizer：
One, the separator of tubular by the space that cooling water is accommodated in voltage-stablizer divide within separator with separator outside
Two parts.The blade diameter length ratio of known vessel is smaller, liquid therein be just less susceptible to occur sloshing phenomenon, and by spacer, under
Original space not being spaced in the two-part blade diameter length ratio both less than voltage-stablizer that separator is isolated, therefore sent out in this two parts
The probability at the life scene of rocking is all lower, and the setting of separator effectively inhibits sloshing phenomenon.
Two, the presence of upper and lower separator limits the Peak Flow Rate that water in container radially flows, even if in severe ring
A certain degree of sloshing phenomenon is generated under the conditions of border, in voltage-stablizer, flow velocity radially is restricted, in such case
Under, the impulsive force suffered by chamber wall is hardly damaged the structure of voltage-stablizer also than relatively limited.
Three, spacer is the upper end small shape in lower end, this overall structure pair greatly with the entirety of under spacer composition
The water of bottom plays a part of " suppression " in voltage-stablizer, voltage-stablizer bottom is more difficult to sloshing phenomenon occur, it is ensured that even if in pole
Under the harsh conditions of end, the heating rod positioned at voltage-stablizer bottom prevents heating rod from burning out all without there is exposed situation.
Four, by suppressing sloshing phenomenon, it is ensured that the water level measuring point in voltage-stablizer is unaffected, so as to improve level measuring
Precision.
To sum up, the new structure of sloshing phenomenon can improve the security of nuclear power plant, reliability in present invention suppression voltage-stablizer
Property and economy.

Position measuring point 112, lower water level measuring point 114 will not be influenceed by the condition of rocking, and nuclear power plant is ensured by monitoring the water level of voltage-stablizer 1
In safe operation state.
3) primary Ioops water filling process.
When needing to carry out water-filling to primary Ioops system, water is entered into voltage-stablizer 1 from Surge line piping, in this process
Water level under spacer 22, spacer 21 is first begin to rise；When water level rises to 21 top of spacer, continue to fill
Water, water flows downwardly into the bottom of voltage-stablizer 1 along spacer 21, until water level rises to the top outside spacer 21；Hereafter
Continue water-filling, until water level reaches the water level of needs, stop water-filling.
Compared with prior art, the new structure of sloshing phenomenon has advantages below in present invention suppression voltage-stablizer 1：
One, the separator of tubular by the space that cooling water is accommodated in voltage-stablizer 1 divide within separator with separator it
Outer two parts.The blade diameter length ratio of known vessel is smaller, and liquid therein is just less susceptible to sloshing phenomenon, and by spacer
21st, original space not being spaced in the two-part blade diameter length ratio that under spacer 22 is isolated both less than voltage-stablizer 1, thus this two
The probability at the scene of being rocked in part is all lower, and the setting of separator effectively inhibits sloshing phenomenon.
Two, the presence of separator limits the Peak Flow Rate that water in container radially flows, even if in rugged environment bar
Under part, a certain degree of sloshing phenomenon is generated in voltage-stablizer 1, flow velocity radially is restricted, in this case, held
Impulsive force suffered by wall is hardly damaged the structure of voltage-stablizer 1 also than relatively limited.
Three, spacer 21 is the upper end small shape in lower end greatly with the entirety of the composition of under spacer 22, and this is integrally tied
Structure plays a part of " suppression " to the cooling water of bottom in voltage-stablizer 1, the bottom of voltage-stablizer 1 is more difficult to sloshing phenomenon occur, really
Even if protecting in the case of exceedingly odious, the heating rod 14 positioned at the bottom of voltage-stablizer 1 prevents heating all without there is exposed situation
Rod 14 burns out.
Four, by suppressing sloshing phenomenon, it is ensured that the water level measuring point in voltage-stablizer 1 is unaffected, surveyed so as to improve water level
The precision of amount.
Five, the new structure that the present invention suppresses sloshing phenomenon is arranged on the bottom of voltage-stablizer 1, will not be to the top of voltage-stablizer 1
Spray system is impacted, and does not also interfere with the heat exchange between shower water and steam.
The present invention suppresses the attended operation of the maintenance with reference to common voltage-stablizer of the new structure of sloshing phenomenon in voltage-stablizer, this
Also need to detect upper and lower separator outward, such as the integrality of burn into weld.
Above disclosed is only preferred embodiments of the invention, its effect be it is convenient it will be understood by those skilled in the art that
And implement according to this, the interest field of the present invention can not be limited with this certainly, therefore made according to scope of the present invention patent
Equivalent variations, still fall within the scope that the present invention is covered.
