Zusammenfassung: | PROBLEM TO BE SOLVED: To enable a liquid spray rod having a spray pipe connection part made of a pipe joint including a union nut to maintain a nozzle direction in a set direction with an unexpected rotation of a spray pipe reliably blocked.SOLUTION: A liquid spray rod that draws a flange 3a on the rear end outer periphery of a spray pipe 3 toward the pipe on the connection partner side by means of a pipe joint 5 that is a combination of a union nut 5a, a nipple 5b, and a seal packing 5c to connect the spray pipe 3 with connection partner pipe is configured that the spray pipe 3 and the nipple 5b have a tapered socket 5d and a tapered annular plug 5e inserted into the socket 5d at corresponding positions to keep the seal packing 5c compressed by the tightening of the union nut 5a, and simultaneously the annular plug 5e press-fitted into the socket 5d.SELECTED DRAWING: Figure 4
【課題】ユニオンナットの含まれた管継手による噴管接続部を有する液体噴霧杆を、噴管の予期せぬ回転が確実に阻止されてノズルの向きが設定方向に維持されるものにすることを課題としている。【解決手段】ユニオンナット5a、ニップル5b、シールパッキン5cを組み合わせた管継手5で噴管3の後端外周の鍔3aを接続相手側の管側に引き寄せて前記噴管3を接続相手の管に接続する液体噴霧杆を、前記噴管3と前記ニップル5bがテーパのソケット5dとそのソケット5dに挿入されるテーパの環状プラグ5eを対応した位置に具備し、前記ユニオンナット5aの締めつけにより、前記シールパッキン5cが圧縮され、同時に前記環状プラグ5eが前記ソケット5dに圧入されるものにした。【選択図】図4 |
