Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a pipe joint which can surely prevent the leakage of fluid even if rubbish and garbage adhere on a plug tip, is easy in the operation of an outer cylinder body, and can be reduced in diameter when achieving a compact size by diameter reduction while simplifying a seal member.SOLUTION: This pipe joint comprises a plug 1 and a socket 4. The plug 1 has a groove part 11. The socket 4 has: a main cylinder body 5 formed with a penetration hole 52; an inner cylinder body 6 arranged at an internal peripheral side of the main cylinder body 5; an outer cylinder body 7 arranged at an external peripheral side of the main cylinder body 5; and a lock member 8 arranged in the penetration hole 52. In the pipe joint, there is formed a seal part which performs secondary seal in two points between an internal peripheral face of a tip side rather than the penetration hole 52 in the main cylinder body 5 and an external peripheral face of the plug 1, and between the lock member 8 and an internal peripheral end of the penetration hole 52 in a state that the plug 1 and the socket 4 are connected to each other.
【課題】プラグ先端部にゴミやチリなどが付着したとしても確実に流体の漏れを防ぐことができ、外筒体が操作しやすく、シール部材の簡略化を図りつつ、小径化によりコンパクト化を図ろうとした場合であっても小径化を可能とした管継手を提供する。【解決手段】本発明の管継手は、プラグ1とソケット4とを備えている。プラグ1は溝部11を有している。ソケット4は、貫通孔52が設けられた主筒体5と、この主筒体5の内周側に設けられた内筒体6と、前記主筒体5の外周側に設けられた外筒体7と、前記貫通孔52内に配置されたロック用部材8とを有する。この管継手は、プラグ1とソケット4とが接続された状態で、主筒体5における貫通孔52よりも先端側の内周面とプラグ1の外周面との間、及び、ロック用部材8と貫通孔52の内周端との間の2箇所で二次シールを行うシール部が形成されている。【選択図】図1 |
