Description

【考案の詳細な説明】
【０００１】
【産業上の利用分野】
本考案は、合成樹脂管または金属管との接続が簡単、かつ確実に行える管継手 に関する。
【０００２】
【従来の技術】
この種の管継手として、例えば特開昭６２ー２５５６９２号公報には、合成樹 脂製継手本体の両端部内面に電熱線を所定間隔で螺旋状に埋設し、該継手本体の 両端部に合成樹脂管の端部を嵌挿してから電熱線に通電して発熱した電熱線で継 手本体の内面と合成樹脂管の端部外面とを同時に溶融させて融着接合する管継手 が提案されている。
【０００３】
【考案が解決しようとする課題】
しかしながら、この管継手は継手本体の両端部に合成樹脂管を嵌挿して融着接 合できるようになっているため、金属管をそのまま接続できないという問題があ った。従って、この管継手に金属管を接続する場合には、予め金属管との継手部 を有する合成樹脂製継手を準備しておいて、この合成樹脂製継手を継手本体に融 着接合してから金属管を接続しなければならないという煩しさがあった。 本考案は，かかる課題を解決したものであって、合成樹脂管または金属管との 接続が簡単、かつ確実に行える管継手を提供するものである。
【０００４】
【課題を解決するための手段】
本考案の管継手は、合成樹脂製継手本体の内面に電熱線を所定間隔で螺旋状に 埋設すると共に、該電熱線の両端部を合成樹脂製継手本体の外面に設けたコネク ターのピンに接続し、また合成樹脂製継手本体の一端部に金属製継手を一体的に 固着して該金属製継手の内面にねじを設けたことを特徴とするものである。
【０００５】
【作用】 合成樹脂製継手本体の内面に電熱線を埋設したので、該継手本体内に合成樹脂 管の端部を嵌挿してから電熱線に通電して発熱させると、継手本体と合成樹脂管 とが強固に融着接合する。一方、継手本体の一端部にねじを有する金属製継手を 固着したので、該金属製継手に金属管を螺合接続できる。また、金属製継手のね じに押えナットを螺合することによって、管端外面に鍔を有する合成樹脂管を接 続できる。
【０００６】
【実施例】
以下、本考案を図面にて詳細に説明する。 図１は本考案の一実施例を示す管継手の半断面図、図２は本考案の他の実施例を 示す管継手の半断面図、図３は図２に示した管継手に合成樹脂管を接続した状態 を示す半断面図である。図中１はポリエチレン等の合成樹脂からなる継手本体、 ４は鋳鉄、砲金等の金属からなる継手であって、合成樹脂製継手本体１の一端部 に金属製継手４が一体的に固着されている。即ち、本考案の管継手は射出成形に よって継手本体１を成形する際に、継手本体１の一端部に金属製継手４を一体的 に固着したものである。
【０００７】 合成樹脂製継手本体１の内面にはポリエチレン等の合成樹脂で外面被覆された 電熱線２が所定間隔で螺旋状に埋設されており、該電熱線２の両端部は継手本体 １の外面に設けたコネクター３のピン３１と接続している。
【０００８】 一方、合成樹脂製継手本体１の一端部に固着した金属製継手４の内面には、ね じ４１が設けられている。図１に示した管継手は、金属製継手４の内径を継手本 体１の内径とほぼ同径に形成してその内面にねじ４１を設けたものであって、該 ねじ４１に金属管の端部に設けた雄ねじを螺合できるようにしたものである。
【０００９】 また、図２に示した管継手は、金属製継手４の内面にねじ４１を設けると共に 内筒体４２を設けたものであって、ねじ４１と内筒体４２との間に形成された隙 間４３の奥部にパッキング５が装着されている。また、金属製継手４のねじ４１ に押えナット６が螺合しており、該ナット６で前記隙間に嵌挿した合成樹脂管の 端部外面に設けた鍔を押圧できるようになっている。
【００１０】 この図２に示した管継手に合成樹脂管を接続する場合、図３に示した如く継手 本体１内に合成樹脂管ａの端部を嵌挿し、コネクター３に配線を接続してから電 熱線２に通電して発熱させる。このとき、合成樹脂管ａのサイズに応じて予め定 められた電流を電熱線２に所定時間通電すると、継手本体１の内面と合成樹脂管 ａの端部外面が過不足なく同時に溶融し、両者が強固に融着接合する。 一方、継手本体１の一端部に固着した金属製継手４の隙間４３に合成樹脂管ｂの 端部を嵌挿してからねじ４１にナット６を螺合すると、合成樹脂管ｂの端部外面 に設けた鍔がナット６に押圧されて管端面がパッキング５と圧接し、水密的に接 続される。
【００１１】
【考案の効果】
以上詳述した如く、本考案の管継手は合成樹脂製継手本体の内面に電熱線を埋 設したので、該継手本体内に合成樹脂管の端部を嵌挿してから電熱線に通電する だけで継手本体に合成樹脂管を強固に融着接合できる。また、この継手本体の一 端部にねじを有する金属製継手を一体的に固着したので、該金属製継手に金属管 を螺合接続することができる。また、金属製継手の内面に設けたねじに押えナッ トを螺合することによって、管端外面に鍔を有する合成樹脂管を接続することが できる。
