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。
