た補修金具に関する。[Detailed description of the invention] [Industrial application field] This invention relates to a repair fitting that is attached to a leakage point of a fluid pipe and used to seal the leakage. Regarding the repair fittings used.
なお、本考案は主として圧力下にある液状流体
に適用される。 Note that the present invention is mainly applied to liquid fluids under pressure.
[従来の技術]
この種の補修金具をして、実公昭37−24256号
公報、実公昭44−9874号公報が提案されている。[Prior Art] This type of repair fitting has been proposed in Japanese Utility Model Publication No. 37-24256 and Japanese Utility Model Publication No. 44-9874.

ケーシングの内面と流体管の外面との隙間空間に
封じ込め止水を行うことになる。 In both known techniques, a fluid pipe surrounding a water leakage point is surrounded by a casing made of a multi-split body, and a packing fitted into a mounting groove on the inner surface of the casing is pressed against the outer surface of the fluid pipe to close the casing. It is designed to be fitted in a fluid pipe in a watertight manner. Thereby, water leakage flowing into the casing from the water leakage point is contained in the gap space between the inner surface of the casing and the outer surface of the fluid pipe, and the water is stopped.

り易く、公知技術における問題点となつている。 However, in both of these known techniques, no matter how the packing is fitted into the mounting groove on the inner surface of the casing, in the process of tightening the casing to the fluid pipe, the leakage pressure between the casing and the fluid pipe gradually increases. The height will increase, and the packing will eventually come out of the mounting groove. Of course, this tendency is more likely to occur the higher the fluid pressure is, but if the surface of the fluid pipe is wet with water and a so-called water supply occurs, it is likely to occur even at a small pressure, which is a problem in known technology. It is a dot.
