本考案は核融合装置用ポートに係り、特に大形の真空容
器に内部観測用として取付けられる核融合装置用ポート
に関する。[Detailed Description of the Invention] The present invention relates to a port for a nuclear fusion device, and particularly to a port for a nuclear fusion device that is attached to a large vacuum vessel for internal observation.
一般に核融合装置の真空容器には、真空容器内部を観測
する目的で種々のポートが取付けられる。Generally, various ports are attached to the vacuum vessel of a nuclear fusion device for the purpose of observing the inside of the vacuum vessel.
従来のポートについて第１図を用いて説明する。A conventional port will be explained using FIG.
真空容器１の近傍のポート２、ベローズ３、および主ポ
ート４を組合せて形成されるポートは真空容器１と連通
して設けられ、主ポート４０反真空容器１側端より内部
を観測する。A port formed by combining the port 2, the bellows 3, and the main port 4 near the vacuum container 1 is provided in communication with the vacuum container 1, and the inside is observed from the end of the main port 40 on the side opposite to the vacuum container 1.
主ポート４の他端（観測側）は、例えば、フランジ５を
ボルト６にて架台７に固定され、フランジ５と主ポート
４は溶接などにより固定されている。At the other end (observation side) of the main port 4, for example, a flange 5 is fixed to a frame 7 with bolts 6, and the flange 5 and the main port 4 are fixed by welding or the like.
このようなポートにむいて、真空容器１が熱、および真
空力などにより変位（変位方向Ｐ）した場合に第２図に
示す様にベローズ３によってこの変位を吸収するように
している。For such a port, when the vacuum container 1 is displaced (in the displacement direction P) due to heat, vacuum force, etc., this displacement is absorbed by the bellows 3 as shown in FIG.
しかしながら、従来の構成では主ポート４（観測側）と
ポート２（真空容器側）とがずれるため、観測範囲は当
初第１図ｄ寸法であったものが第２図Ｂ寸法のととくせ
ばめられてし！い、充分な観測が出来ない欠点があった
。However, in the conventional configuration, main port 4 (observation side) and port 2 (vacuum vessel side) are misaligned, so the observation range, which was originally dimension d in Figure 1, is now intertwined with dimension B in Figure 2. Teshi! However, there was a drawback that sufficient observations could not be made.
そこで、上記のように、せばめられた観測範囲Ｂを、少
しでも拡げるために、ベローズ３、ポート２、および主
ポート４の内直径寸法ｄを、ｄ＋Ｋに拡大（Ｋは拡大寸
法）することが提案される。Therefore, as mentioned above, in order to expand the narrow observation range B even a little, it is possible to expand the inner diameter dimension d of the bellows 3, port 2, and main port 4 to d+K (K is the enlarged dimension). Suggested.
然るに、ポートは以下に述べるような設置条件を克服す
る必要がある。However, the ports must overcome installation conditions such as those described below.
即ち、ポートは第１２図に示すようにトロイダル磁場コ
イル２０、およびポロイダル磁場コイル２１〜２４等の
狭いスペースをくぐりぬけるようにして設ける必要があ
る。That is, the port needs to be provided so as to pass through a narrow space such as the toroidal magnetic field coil 20 and the poloidal magnetic field coils 21 to 24, as shown in FIG.
また、ポート自体が摂氏数百度に及ぶ高温に熱せられる
ため、トロイダル磁場コイル２０、ポロイダル磁場コイ
ル２１〜２４、その他の周囲部品に熱的な害を与えない
ようにするにポート２、主ポート４、及びベローズ３に
片側数拾耗もの断熱層２５を巻付けるため、ポート設置
スペースを広く確保する必要がある。In addition, since the ports themselves are heated to a high temperature of several hundred degrees Celsius, port 2 and main port 4 are required to prevent thermal damage to the toroidal magnetic field coil 20, poloidal magnetic field coils 21 to 24, and other surrounding parts. , and because the bellows 3 is wrapped with several wearable heat insulating layers 25 on one side, it is necessary to secure a wide space for installing the ports.
更に、ポートと周囲部品との間隔が狭いか、又は接触し
ている場合、その部分を通じて真空容器１、ポート周囲
部品からなる電気回路が出来、肝心のプラズマの形成に
乱れを生じるか、又はプラズマが形成されないことにな
ってし捷う。Furthermore, if the distance between the port and surrounding parts is narrow or there is contact, an electric circuit consisting of the vacuum vessel 1 and the port surrounding parts will be formed through that part, which may disturb the important plasma formation or cause plasma It ends up not being formed.
このため、周囲の部品とポートとの間隔を充分大きく採
る必要があり、一層広いポート設置スペースを確保しな
くてはならない。For this reason, it is necessary to provide a sufficiently large distance between the surrounding parts and the port, and it is necessary to secure an even wider space for installing the port.
以上述べたようなポート設置条件を克服するだけでも容
易でなく、１して、ポートの内径寸法を拡大する（前記
観測範囲の縮少を防ぐ）ことは大変難しいものとなって
し１う。It is not easy to overcome the above-mentioned port installation conditions, and it is also very difficult to enlarge the inner diameter of the port (to prevent the observation range from decreasing).
本考案は、上述の点に鑑み成されたもので、その目的と
するところは、ポートの設置条件を克服し観測範囲縮少
を防ぐことのできる核融合装置用ホードを提供するにあ
る。The present invention has been developed in view of the above points, and its purpose is to provide a hoard for a nuclear fusion device that can overcome the port installation conditions and prevent a reduction in the observation range.
本考案はベローズを含む真空容器付根側のポートの内径
を、他の部分のポート内径より太きくすることにより、
所期の目的を遠戚するように威したものである。This invention makes the inner diameter of the port on the base side of the vacuum container, including the bellows, larger than the inner diameter of the port in other parts.
It was meant to be a distant relative of the intended purpose.
以下、図示した実施例に基づいて本考案を説明する。Hereinafter, the present invention will be explained based on the illustrated embodiments.
尚、符号は従来と同一のものは同符号を使用する。Note that the same reference numerals are used for the same parts as in the past.
第３図、及び第４図に本考案の一実施例を示す。An embodiment of the present invention is shown in FIGS. 3 and 4.
線図に示す本実施例でも主ポート４の周囲に近接してポ
ロイダル磁場コイル、およびトロイダル磁場コイルの部
品が在るがここでは省略している。In this embodiment shown in the diagram, there are parts of a poloidal magnetic field coil and a toroidal magnetic field coil near the main port 4, but they are omitted here.
本実施例では主ポート４は、その内径をその１寸とし、
周囲に近接して部品がない真空容器側のポート、および
ベローズを主ポート４より大きい内径寸法にしたポート
８、ベローズ９で形成し、レデューサ−１０を介して主
ポート４と接続している。In this embodiment, the main port 4 has an inner diameter of 1 dimension,
It is formed of a port on the side of the vacuum vessel that has no parts nearby, and a port 8 and a bellows 9 whose inner diameter is larger than that of the main port 4, and is connected to the main port 4 via a reducer 10.
ここで、真空容器側のポート８の内径寸法をＤ、主ポー
ト４の内径寸法をｄ、観測側と真空容器１との相対移動
量をδ、移動後の観測範囲をＢ、そして観測範囲減少量
をｅとすると次のような関係となる。Here, the inner diameter of port 8 on the vacuum vessel side is D, the inner diameter of main port 4 is d, the amount of relative movement between the observation side and vacuum vessel 1 is δ, the observation range after movement is B, and the observation range decreases. If the quantity is e, the following relationship is obtained.
Ｂ＝ｄ−ｅ＝（ｄ／２ ）−δ＋（Ｄ／２ ）依って、
ｅ＝δ−（（Ｄ−ｄ）／２）
つ捷り、この式より相対移動量δを一定とすれば、ポー
ト８と主ポート４との内径寸法（Ｄ−ｄ）を太きく採る
程観測範囲減少量ｅが小さくなることがわかる。B=de=(d/2)−δ+(D/2) Therefore,
e=δ-((D-d)/2) From this formula, if the relative movement amount δ is constant, the larger the inner diameter dimension (D-d) of port 8 and main port 4, the larger the It can be seen that the observation range reduction amount e becomes smaller.
即ち、主ポート４の内径寸法ｄに対し、真空容器側のポ
ート８の内径寸法りを出来るだけ大きく採れば観測範囲
の減少量が小さくなる。That is, if the inner diameter dimension of the port 8 on the vacuum vessel side is made as large as possible with respect to the inner diameter dimension d of the main port 4, the amount of decrease in the observation range will be reduced.
更に、内径寸法差の半分（Ｄ−ｄ）／２を、前記相対移
動量δより大きく採れば、つオリ（Ｄｄ）〉２δとすれ
ば、第５図、及び第６図の如く、当初要求された観測可
能範囲Ｂは、主ポート４の内直径ｄを保障され、むしろ
、その差（（Ｄ−ｄ）／２−δ）だけ相対移動の余裕代
ｅ′を得ることが出来る。Furthermore, if half of the inner diameter dimensional difference (D-d)/2 is taken to be larger than the relative movement amount δ, then if (Dd)>2δ, the initial requirement is obtained as shown in Figs. 5 and 6. In the observable range B, the inner diameter d of the main port 4 is guaranteed, and rather, an allowance e' for relative movement can be obtained by the difference ((D-d)/2-δ).
このように相互の内径寸法差（Ｄ−ｄ）は、相対移動量
δの２倍（２δ）より大きいことが最も望ましい。As described above, it is most desirable that the mutual inner diameter size difference (D-d) is larger than twice the relative movement amount δ (2δ).

も上述した実施例と同様の効果が得られる。7 shows an example in which a flat plate 11 is used instead of the reducer 10 in FIG. 3, and FIG. 8 shows an example in which flanges 12, 13 and bolts 1
4 is used to connect the next side, Figure 9 is the flat plate 1 in Figure 7.
1. An example in which a tapered bellows 17 is used instead of the bellows 9, FIG. 10 omits the port 8 shown in FIG. Example where the inner diameter dimension d is larger than that of No. 4, No. 11
The figure shows an example in which a tapered bellows 17 is used in place of the reducer 10 and bellows 9 shown in FIG. 10, and in both cases the same effects as in the above embodiment can be obtained.
以上説明した本考案の核融合装置用ポートによれば、真
空容器と観測側との間の相対移動により観測範囲が極度
に狭められることなく、常に一定範囲以上の観測が可能
なポートを提供出来るため核融合装置に採用する場合に
は非常に有効である。According to the fusion device port of the present invention described above, the observation range is not extremely narrowed due to relative movement between the vacuum vessel and the observation side, and a port that can always observe a certain range or more can be provided. Therefore, it is very effective when used in nuclear fusion devices.
