REPAIR MATERIAL INJECTION TOOL
PROBLEM TO BE SOLVED: To provide a repair material injection tool capable of inexpensively and surely regulating a moving quantity of a ball of a check valve with a simple structure.SOLUTION: A repair material injection tool 1 comprises a check valve 11 in a cylindrical part 2 integrally formed of a single material. The check valve 11 comprises a valve seat 12 on the inner periphery 2c of the cylindrical part 2, a ball 13 and a stopper 14 for regulating a moving quantity of the ball 13. The stopper 14 comprises a ball receiving part 18, a plurality of fitting parts 19 fitted to the inner periphery 2c of the cylindrical part 2 and a plurality of inclined-shaped arm parts 20 for connecting the respective fitting parts 19 to the ball receiving part 18. The respective arm parts 20 convert force F for pressing the ball receiving part 18 through the ball 13, into force G for diametrically expanding the respective fitting parts 19.SELECTED DRAWING: Figure 6
【課題】構造が簡単で、コスト安価に逆止弁のボールの移動量を確実に規制できる補修材注入用治具を提供する。【解決手段】補修材注入用治具１は、単一の材料で一体に形成された筒状部２内に逆止弁１１を有する。逆止弁１１は、筒状部２の内周２ｃの弁座１２と、ボール１３と、ボール１３の移動量を規制するストッパ１４を有する。ストッパ１４は、ボール受け部１８と、筒状部２の内周２ｃに嵌合された複数の嵌合部１９と、各嵌合部１９をボール受け部１８に連結する複数の傾斜状の腕部２０とを有する。各腕部２０が、ボール１３によってボール受け部１８が押圧される力Ｆを、各嵌合部１９を拡径する力Ｇに変換する。【選択図】図６
