Abstract
Description
本発明は、管およびチューブの接続用継手に関するものである。 The present invention relates to a joint for connecting pipes and tubes.
この種の接続用継手は、図8(a)(b)に示すように、一方の継手11にリング12を挟んで短パイプ13の一端を差し込み、ナット14締めしてから、該短パイプ13の他端を他方の継手11にリング12を挟んで差し込み、遊びナット14にて締め付けて接続して管路を形成するようにしてきている。
As shown in FIGS. 8 (a) and 8 (b), this type of connecting joint is inserted into one
このようにして継手間の接続に多くの部材を要すことは継手間の接続に多くの手間がかかり、接続した継手間に多くの部材があることで気密,水密洩れのおそれが生じ、また接続後の点検個所が多となって点検を容易でないものにしているという課題があった。 The fact that many members are required for connection between joints in this way takes a lot of trouble in connecting the joints, and there are many members between the connected joints, resulting in the risk of airtightness and watertight leakage. There was a problem that the number of inspection points after connection was too large, making inspection difficult.
本発明は、継手の一面に雄管を設け、他面に該雄管の外径を内径とする雌管を形成し、該継手の雄管を該雌管の内径を拡げながら圧入することにより2個の継手間を回転自在に接続し、且つ該雌管の外側からの押圧縮径により該雌管の内面を雄管の外面に圧接させ、さらに該雌雄管の接合面に凹凸の噛合環を1乃至数個づつ設けて噛合止めすることで、かかる課題を解決するようにしたのである。 The present invention provides a male pipe on one side of the joint, forms a female pipe having the outer diameter of the male pipe as an inner diameter on the other side, and press-fits the male pipe of the joint while expanding the inner diameter of the female pipe. Two joints are rotatably connected, and the inner surface of the female tube is pressed against the outer surface of the male tube by a pressing / compressing diameter from the outer side of the female tube. Such a problem is solved by providing one or several of each and engaging with each other.
本発明は、継手間を直接圧入により接続するので、短時間にて能率よく接続することができるという効果を生ずる。 According to the present invention, since the joints are directly connected by press-fitting, there is an effect that the connection can be efficiently made in a short time.
短パイプ,リング遊びナットなどの部材を一切不要にするので、気密漏れ,水洩れの個所がなくなり、その点検も容易になるという効果を生ずる。 Since members such as short pipes and ring play nuts are unnecessary, there is no effect of airtight leakage and water leakage, and the inspection can be facilitated.
また本発明の継手は雄管と雌管の間の流路を直線形とするほか、L字形などに曲げ、また中間に分岐部を設けて十字形などにすることができ、且つ回転自在の接続にて、管およびチューブを直線のほか、曲折と多岐の分岐管路を能率よく形成し得るという効果を生ずる。 In addition, the joint of the present invention has a flow path between the male pipe and the female pipe in a straight shape, can be bent into an L shape, and can be formed in a cross shape by providing a branch portion in the middle, and is rotatable. The connection produces an effect that the pipe and the tube can be formed in a straight line, and a bent and various branch pipes can be efficiently formed.
本発明は管およびチューブの接続用継手であって、該継手の一面に雄管を設け、他面に該雄管の外径を内径とする雌管を形成し、該継手の雄管を該雌管の内径を拡げながら圧入することにより2個の継手間を回転自在に接続し、且つ該雌管の外側からの押圧縮径により該雌管の内面を雄管の外面に圧接し、さらに該雌雄管の接合面に凹凸の噛合環を1乃至数個づつ設けて噛合止めするようにした管およびチューブの接続用継手にある。 The present invention is a joint for connecting pipes and tubes, wherein a male pipe is provided on one side of the joint, a female pipe having an outer diameter of the male pipe as an inner diameter is formed on the other side, and the male pipe of the joint is connected to the male pipe. By press-fitting while expanding the inner diameter of the female tube, the two joints are rotatably connected, and the inner surface of the female tube is pressed against the outer surface of the male tube by the pressing and compressing diameter from the outer side of the female tube. It is a joint for connecting tubes and tubes in which one or several uneven engagement rings are provided on the joint surface of the male and female pipes to be engaged with each other.
図1は本発明の1実施例であって、四角立方体形をした継手1を複数個形成する。該各継手1はその一面に雄管2を設け、他面に雄管2の外形を内径とする雌管3を設ける。図1(b)に示すように継手1の雄管2を隣りあわせした継手1の雌管3の内径を拡径しながら雌管3内に圧入して継手1,1間を回転自在において接続させる。図1(c)に示すように雄管2の外形と雌管3の内径との間には雌管3の拡径分において間隙Kが生ずるが、外側から雌管3を押し縮径して該間隙Kを解消して雌雄管2,3間の接合面を回転自在にて気密,水密裡に接面させる。
FIG. 1 shows an embodiment of the present invention, in which a plurality of
各継手1はポリテトラフルオロエチレン(4フッ化)樹脂(PolyTetraFlouroEthylene、以下PTFEと称す)またはテトラフルオロエチレン−パーフルオロアスコキシエチレン共重合体(以下PFAと称す)にて形成する。PTFEまたはPFAはフッ素系の熱可塑性樹脂で炭素の周りをフッ素が取り囲んでいる構造により化学的に非常に安定していて、全原子中もっとも電気陰性度が高いフッ素は炭素原子と硬く結合する結合力の高さにより化学的に分離することがなく、よって雌管3の内径を拡径し、縮径してもその過程で脆弱化して裂損したりすることはなく、一旦拡径しても押し縮径により完全に元形に復帰して且つその状態にて再び安定することとなる。歪んだり戻り開きすることがないのである。
Each
さらにPTFEまたはPFAはフッ素の表面エネルギーが非常に小さいため合成樹脂の中で最も低い摩擦係数を持ち、自己潤滑性があり、耐摩耗性にも優れているため、接続した継手1,1間、すなわち雄管2と雌管3間は長期に亘ってスムーズに回転することが可能であり、また耐熱性、耐薬品性にもすぐれていて管路としてあらゆる状況の気体,液体の流通にも適するものである。
Furthermore, PTFE or PFA has the lowest friction coefficient among the synthetic resins because the surface energy of fluorine is very small, self-lubricating, and excellent wear resistance. In other words, the
また接合面を挟んで雄管2と雌管3に1乃至数個づつの噛合環4,5を設けて噛合止めして雌管3の抜出を防止する。
噛合環4,5は図2(a)に示すように垂直面4aのほか、図2(b)に示すように抜けない方向の斜面4bを設けることもある。噛合環4,5の噛合止めによって抜出は確実に防止され、従来の継手に較べて著しく高い耐圧性能を有すものとなる。噛合環4,5は間隔を置いて2個,3個において設けることもある。なお、6は溝嵌めした封止リングである。封止リング6は、噛合環4,5のいずれか一側に設けるほか、図3(b)に示すように噛合環4,5を挟んだ両側に設けることもある。
Further, one or
In addition to the

FIG. 4 and subsequent figures show connection examples of the
管7a,チューブ7bの接続用の接続部は、図5(a)(b)(c)に示すように雄ネジ形2a,2b、雌ネジ形3aなど各形状の組合わせにて形成することもある。
As shown in FIGS. 5 (a), 5 (b), and 5 (c), the connecting portion for connecting the
図6(a)(b)は、継手1a内にL字通路1bを設けてL字曲折形,S字曲折形の管路9a,9bを形成した例を示し、図6(c)は継手1cにクロス十字の通路1dを設けて十字分岐形の管路9cを形成した例、図6(d)(e)は継手1eにT字形の通路1f,1gを設けて分岐した管路9d,9eを形成した例を示している。
6 (a) and 6 (b) show an example in which an L-
なお、継手1内の通路を変化させることで図示以外の管路も形成し得るものである。さらに継手を円筒形,球形等に形成して多数の放射形の分岐通路を設けた管路を形成することもできる。継手は管7a,チューブ7bの内径1mm乃至50mmあるいはそれ以上の大きい径に合わせて大小の大きさにて形成する。
Note that pipes other than those shown in the figure can be formed by changing the passage in the
図7は継手1を複数個接続して各継手に管7aまたはチューブ7bを接続して分岐するようにした例を示すもので、図示するように継手1の1個に1本の管7a,チューブ7bを接続するほか、前記した十字分岐形にして複数本の管,チューブを接続するようにすることもある。また接続した各継手1,1間は回転自在によって自由な方向に向けることができる。

本発明の接続用継手は、短時間にて能率よく接続することができ、気密漏れ,水洩れのおそれがなく、点検も容易で、回転自在において直線のほか曲折と多岐の分岐管路形成用の継手として広範に利用することができる。
