Brief description
The schematic diagram of the passive exhaust apparatus of nuclear power plant that Fig. 1 provides for the present invention.
Fig. 2 is the schematic diagram of structure closed mode shown in Fig. 1.
Wherein：1- frame assembly 2- louver assembly 3- sealing strip 4- tension assembly 5- connecting rod.
Specific embodiment
Understandable for enabling the above objects, features and advantages of the present invention to become apparent from, below in conjunction with the accompanying drawings and specifically real
The present invention is further detailed explanation to apply mode.
As shown in Figure 1-2, the passive exhaust apparatus of nuclear power plant, it includes：Frame assembly；Louver assembly, it is movably
It is arranged in described frame structure, is configured for bearing fluid-load, separate both sides headroom；And tension assembly, its setting
On described louver assembly, and there is spring tension.Described tension assembly is configured using described spring tension, when described blinds
When the stress load of assembly reaches starting differential pressure predetermined described spring tension, described louver assembly is driven gradually to open, and
Reach traffic requirement eventually, thus balancing both sides pressure reduction, when described louver assembly stress load is less than predetermined described spring tension
When, drive described louver assembly to progressively close off, the final plant closure when both sides pressure reduction reaches closing pressure reduction.Described louver assembly has
Multiple blinds；The plurality of blinds passes through connection-rod linkage.On described frame assembly, configuration seal groove and sealing strip are to meet sealing
The requirement of leakage.
1. the structure of equipment and function
The exhaust apparatus of the present embodiment is mainly made up of frame assembly, louver assembly, tension assembly, sealing strip, connecting rod etc..
Frame assembly plays support and installs positioning action；Louver assembly is used for bearing fluid-load, separates both sides headroom, louver assembly
Totally 4 groups, pass through connecting rod between every group and be connected, keep it turned on the uniformity of closing motion；Tension assembly utilizes the work of spring tension
With when louver assembly stress load reaches the predetermined spring tension of starting differential pressure, blinds starts gradually to open, and is finally reached
Traffic requirement, thus balancing both sides pressure reduction, when louver assembly stress load is less than predetermined spring tension, blinds starts gradually
Close, the final plant closure when both sides pressure reduction reaches closing pressure reduction.On frame assembly along blinds surrounding circumferential arrangement seal groove with close
Strip of paper used for sealing is meeting the requirement of sealing leak.
2. the operation of equipment and use
The exhaust apparatus frame assembly of the present embodiment is fixed on IRWST steel module wall by welding manner, and both sides are divided
Not Wei IRWST and safe shell-space, louver assembly is closed.Pressure reduction between IRWST and containment reaches unlatching
During pressure reduction, louver assembly blade is acted on by water vapour pressure, and its opplied moment on blade is more than the bullet of tension assembly
During the moment that spring pulling force produces, blinds starts to rotarily open along rotating shaft, and eventually arrives at predetermined design discharge, reaches exhaust work(
Can require.When pressure reduction is reduced to predetermined closing pressure reduction twice, in the presence of spring tension, louver assembly begins to shut off, and
Finally remain off, be pressed on the sealing strip on frame assembly by the effect of spring tension, by the change in sealing strip
Shape, realizes sealing function.
The exhaust apparatus of the present embodiment is used for the row in nuclear power plant's passive cooling system between IRWST and safe shell-space
Gas.When both sides pressure reduction is more than predetermined starting differential pressure, the unlatching that exhaust apparatus can be passive, it is finally reached design discharge,
When both sides pressure reduction is less than predetermined closing pressure reduction, exhaust apparatus starts to progressively close off, and final plant closure, realizes the sealing requiring
Function.
Compared with prior art, the present embodiment has the advantages that：
1st, the passive exhaust apparatus of nuclear power plant that the present embodiment provides, using passive design, the opening and closing of device
Realized by Fluid pressure and spring tension；Tension assembly layout structure and position can make louver assembly be produced by spring tension
Moment be descending curve, improve the flow negotiability of device；Louver assembly adopts the compressing knot of thin-walled coating
Structure is big, rigidly good from heavy and light, intensity；Encrypt the sealing structure form of strip of paper used for sealing, good sealing effect, follow-up replacing using seal groove
Easy to maintenance.
In this specification, each embodiment is described by the way of going forward one by one, and what each embodiment stressed is and other
The difference of embodiment, between each embodiment identical similar portion mutually referring to.For system disclosed in embodiment
For, due to corresponding to the method disclosed in Example, so description is fairly simple, referring to method part illustration in place of correlation
?.
Those skilled in the art can use different methods to each specific application realize described function, but
It is this realization it is not considered that beyond the scope of this invention.
