Abstract
Description
一態様において、本開示のフィッティングは、鉄管サイズ(IPS)からダクタイル鋳鉄(DI)およびそれ以上の範囲のサイズを含む広範囲のパイプサイズにわたって、密封と拘束の両方を達成できる。一例において、フィッティングは中空体の内部に拘束され、ガスケットシールにより裏打ちされる。分割された拘束要素が、中空体の円錐形状面の内側に配置された周方向エラストマガスケットに結合される。導引機構により拘束要素が円錐に下方導引されると、ガスケットとともにパイプまで縮小されて、パイプ上での密封と拘束の両方を達成する。フィッティングが設置された後でパイプ内の内圧が上昇すると、ガスケットと拘束要素とがさらに付勢されてパイプを密封し拘束する。
図3を参照すると、バレルスリーブ12は各端部に環状面または肩部32を有する。肩部32は、エンドリング20の類似形状環状部分34のための当接箇所となる。このようにして、エンドリング20がバレルスリーブ12に対して回転可能であるように、エンドリング20の環状部分がバレルスリーブの対応環状面32と摺動接触状態で当接する。この例は環状面または肩部を含むが、本開示の全体を検討すると当業者にはすぐに明白となるように、本開示は、エンドリングをスリーブ12に対して回転させる他の取付構造も内含する。
図6を参照すると、エンドリング20は複数の傾斜面30またはランプ区分を有する。各傾斜面は、パイプの周りにガスケットアセンブリ18を締結するカム面として機能する。
これから、図7〜10を参照してガスケットアセンブリ18についてさらに説明する。図7を参照すると、ガスケットアセンブリ18は環状ゴムガスケット部材44を含む。ガスケット部材44(または「ガスケット」)は、弛緩または「非締結」条件にある時の断面が図4に図示されている。複数の把持部材46が、ガスケット44の上面48に当接している。やはりガスケット44の周囲に分散された導引リンク機構50により、把持部材46はガスケット44の周囲に環状構成で保持されている。
図4および5は、上で説明された様々な部品がどのように協働してパイプ端部をフィッティング10にクランプするかを図示している。最初に図4を参照すると、パイプ70の最内端部がバレルスリーブ12の内側のどこかを終端とする状態(図3参照)で、継手本体10の開放端部(68で概略指示)へパイプ66が挿入される。他の例では、フィッティングのタイプに応じて、パイプ70の最内端部がフィッティングの端部に延在してこれよりも突出しうる。バレル部分12は内側テーパ面72を有する。この例では、テーパ面72は継手の開口端部に向かって対称的に収束している。言い換えると、テーパ面72は、継手の内側から外側へ向かう方向に中心軸線を中心として対称的に収束するのである。この例では、ガスケット44の外面74と(前に説明された)把持部材46の平滑外面60とは、テーパ面72の傾斜と適合する類似の傾斜を有する。
上記の設計の他の実施形態は、図6に18で図示されたガスケットアセンブリの構成の変更に関するものである。図16を参照すると、例えば、「拘束部」を含まずに、つまり把持部材46を使用せずに、上に説明された導引機構を実行すること(「垂直」力を軸方向「導引」に変換)が可能でありうる。同様に、導引フックのすべてではなくいくつかに把持部材を使用することも可能である。例えば、図20はフィッティングを図示しており、この例でフィッティングは、突起50よりも少ない把持部材46を含むパイプ継手10aである。
上に説明された部品を製造する多様な方法が存在するが、上記の部品の多くは、バレルスリーブ12およびエンドリング20と同様に、例えば鋳造されうる。ガスケット44は従来のゴム材料で製作されるであろう。把持部材46および導引フック50は、例えば鋼、ステンレス鋼、またはダクタイル鋳鉄など、様々な材料から製造されうるだろう。バレルスリーブ12は、継手の使用を容易にするハンドル84を含みうる。上記のように、フィッティング10はここでは端部間継手として説明されているが、用途に応じて、「T」継手または単一端継手など他の手法で構成されうる。
