Abstract
It the utility model is related to classification pressure-bearing containment peculiar to vessel, including containment, interior pressure-control valve and external pressure force control valve, it is characterized in that the top of containment, bottom and surrounding are the double-decker of inner panel and outside plate composition, containment is divided into inner cavity and hollow layer by inner panel and outside plate, hollow layer is closed cavity, interior pressure-control valve is installed on inner panel, the entrance and exit of interior pressure-control valve is connected with inner cavity and hollow layer respectively, external pressure force control valve is installed on outside plate, and the entrance and exit of external pressure force control valve is connected with containment external aqueous environment and hollow layer respectively.Using the utility model, change containment and bear internal pressure and the mode of external pressure so that external load function power is rationally allocated between containment inner panel and outside plate, so as to effectively enhance containment pressure-bearing mechanical property on the premise of containment weight is not increased.The utility model is simple in structure.
Description
Technical field
Nuclear safety safeguard structure is the utility model is related to, classification pressure-bearing containment specifically peculiar to vessel.
Background technology
One defence line of the containment as nuclear safety, occurs loss of-coolant accident (LOCA) and when generation shipwreck event safety in nuclear equipment
When shell falls into the water with nuclear equipment, ensure that core radio gas is not leaked and water cannot be in contact to avoid right with nuclear equipment
Environment, which produces, to be played the role of vital in pollution, thus needed containment to have and enough born internal pressure, external pressure and steady
Sexuality.Common containment structure design is to use strong frame scheme, in order to ensure enough mechanical properties, can only constantly be increased
Add the weight of structure, and this measure often brings adverse effect to the overall performance of ship.Therefore, design a kind of simple in structure
And the classification pressure-bearing containment peculiar to vessel of containment pressure-bearing mechanical property can be strengthened on the premise of containment weight is not increased very
It is necessary.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure and can strengthen on the premise of containment weight is not increased
The classification pressure-bearing containment peculiar to vessel of containment pressure-bearing mechanical property.
To achieve the above object, the utility model adopts the following technical solution：Classification pressure-bearing containment peculiar to vessel, including safety
Shell, interior pressure-control valve and external pressure force control valve, form it is characterized in that the top of containment, bottom and surrounding are inner panel with outside plate
Containment is divided into inner cavity and hollow layer by double-decker, inner panel and outside plate, and hollow layer is closed cavity, interior pressure-control valve installation
On inner panel, the entrance and exit of interior pressure-control valve is connected with inner cavity and hollow layer respectively, and external pressure force control valve is installed on outer
On plate, the entrance and exit of external pressure force control valve is connected with containment external aqueous environment and hollow layer respectively.
Using the utility model, change containment and bear internal pressure and the mode of external pressure so that external load function power is being pacified
Rationally it is allocated between shell inner panel and outside plate, is held so as to effectively enhance containment on the premise of containment weight is not increased entirely
Press mechanical property.The utility model is simple in structure.
Brief description of the drawings
Fig. 1 is the utility model isometric structure diagram；
Fig. 2 is the utility model front view；
Fig. 3 is the sectional view along A-A of Fig. 2.
In figure：1- containments；1.1- inner panel；1.2- outside plate；1.3- inner cavity；1.4- hollow layer；Pressure-control valve in 2-；3-
External pressure force control valve.
Embodiment
The utility model is further described with reference to the accompanying drawings and embodiments, but the embodiment should not be construed as pair
The limitation of the utility model.
Classification pressure-bearing containment peculiar to vessel as depicted, including containment 1, interior pressure-control valve 2 and external pressure force control valve
3, top, bottom and the surrounding of containment 1 are the double-decker that inner panel 1.1 is formed with outside plate 1.2, and inner panel 1.1 and outside plate 1.2 will pacify
It is closed cavity that full shell 1, which divides for inner cavity 1.3 and hollow layer 1.4, hollow layer 1.4, and interior pressure-control valve 2 is installed on inner panel 1.1,
The entrance and exit of interior pressure-control valve 2 is connected with inner cavity 1.3 and hollow layer 1.4 respectively, and external pressure force control valve 3 is installed on outside plate
On 1.2, the entrance and exit of external pressure force control valve 3 is connected with 1 external aqueous environment of containment and hollow layer 1.4 respectively.
When loss of-coolant accident (LOCA), which occurs, for the nuclear equipment in containment 1 causes containment to be subjected to interior air pressure, containment inner panel 1.1
On interior pressure-control valve 2 automatically open up so that a part of gas is entered in the hollow layer 1.4 of containment, works as hollow layer
1.4 air pressure reaches a timing internal pressure force control valve 2 and is automatically closed and hollow layer 1.4 is sealed.In this case, pacify
The active force that full shell inner panel 1.1 is born will reduce, and the active force that containment outside plate 1.2 is born then increases.
When ship because when accident causes 1 submerged of containment, containment outside plate 1.2 is in external aqueous environment, outside
Pressure-control valve 3 automatically opens up, so that water is entered in hollow layer 1.4, the external pressure force control valve when hollow layer 1.4 is filled up by water
3 are automatically closed, and realize the sealing to hollow layer 1.4.In this case, when pressure of the containment outside plate 1.2 because bearing water
And when being deformed, due to the Incoercibility of water, external load function power can be passed by the water in outside plate 1.2 and hollow layer 1.4
It is delivered on containment inner panel 1.1.
The content not being described in detail in this specification, belongs to the prior art known to those skilled in the art.
