Description
Claims (4)
- 管状熱交換器用の内部チューブシートの密閉構造であって、
ショルダ(51)とチューブシート(4)間に固定されたガスケット(21)を具え、前記ガスケット(21)は螺旋状巻回構造に構成されるがこれに如何なる金属リングも有さず、接合部材に位置決め溝がなく、
前記チューブシートの外側には、チャネルボックス(22)が、その内面が前記チューブシート(4)の外径に設けられたショルダ上にあるとともに、チャネルボックス(22)の外面は直径が減少して前記プッシュボルト(13)の中心線に整列するように構成され、前記チャネルボックスの外面は環状リング(12)に対向して置かれこれに取り付けられ、プッシュボルト(13)が内部フランジ(24)の外面に届くねじ穴に取り付けられており、
前記プッシュボルト(13)は締められたとき前記環状リング(12)をその外側から荷重し、これがチャネルボックス(22)とチューブシート(4)を通してガスケット付のジョイントを荷重し;この負荷への外側方向への反応が分割剪断リング(25)により曲げストレスではなく本質的に剪断ストレスの動作により受けられ、ガセット(23)がチャネルボックスの壁と環状リング(12)の間に設けられ、これによりプッシュボルト(17)を締めると、内部圧縮リング(18)、ダイヤフラム(19)、および内部スリーブ(20)を介して環状リング(12)を荷重し、前記環状リング(12)の負荷はガセット(23)を通ってチャネルボックス(22)へ、最終的にチューブシート(4)へ伝達されて前記ガスケット(21)が荷重され;小径(すなわち約25mmから250mm)用にチャネル(101)の内径は、円錐部分(102)が続くチューブシートと近接した隙間嵌め(running fit)を実現すべくクリアランスが低減されており、それ以外の部分は通常のクリアランスであることを特徴とする構造。 - 請求項1に記載の環状熱交換器用の内部チューブシートの密閉構造において、前記ガスケット(21)が、金属リングを有さない螺旋巻回型、空洞金属Oリング型、空洞金属Cリングまたはその類似物のような弾力特性を有することを特徴とする構造。
- 請求項1に記載の環状熱交換器用の内部チューブシートの密閉構造において、前記チャネルボックス(22)における2つの端面間の部分は様々な形状をとりうるが、製造の容易のため好適に円錐形であることを特徴とする構造。
- 請求項1に記載の環状熱交換器用の内部チューブシートの密閉構造において、添付の図面を参照して実質的に本書に記載された構造。
