Description
れ、かつスリットの底に当たるスペース部分27にて隣りの一端部分同士が完全に離れており、パッキング本体20の圧縮じわの発生を防止し、管体11の位置変動に対する追従性能を向上するように意図されている。
は、予め管体11に継手リング15を嵌め合わせ、次いでパッキング本体20を管体11に同様に嵌め合わせる。その際、係止端部29が管体11の端部を確実に覆うように注意し、パッキング本体20の一端部分22が継手リング15の内側斜面19と管体外面との間に入り込むようにする。さらに、パッキング本体20の外側を覆うよう継手管12に嵌め合わせ、そのフランジ部14と前記継手リング15のボルト孔にボルト16を差し込
み、かつナット17を螺合して締結作業を行う。

Claims (1)
- 建物の排水管などの管体を接続する管継手に使用するもので、管体の外面と継手部の内面との間に介装するため、弾性材によって形成されたパッキングであって、管体の外面に嵌合可能な環状部と、環状部の一端から管軸方向へ延びる一端部分と、環状部の他端から管軸方向へ延びる他端部分とを有するパッキング本体を具備し、パッキング本体の一端部分が独立的に動き得るようにスリットによって複数部分に分割されており、ボルトによる継手部の締結時に、継手部に設けられている内側斜面と管体外面との間に介在する剛体球を、上記分割各部分に1個又は2個以上設けた構成を有する可撓管継手用パッキング。
