Water supply stop valves are usually installed in underground steel pipes (manholes), so when replacing the water stop valve, do not use tools such as spanners to close the water stop valve in the narrow steel pipe. Conventionally, it is necessary to break the concrete or the like on which the stop valve is installed and dig up the earth and sand to a place where the tool can be used, since it is not rotated by a tightening nut provided on the upper part of the outer surface.
このため、従来は、止水弁の取替えが甚だ面倒
であるという問題があつた。 For this reason, conventionally there has been a problem that replacing the water stop valve is extremely troublesome.
そこで、この考案は、止水栓が設置されている
鉄筒内に挿し込み、止水弁の締付けナツトをつか
んで回転させることにより、容易に止水弁の取替
えができるレンチを提供しようとするものであ
る。 Therefore, this invention aims to provide a wrench that allows the water stop valve to be easily replaced by inserting it into the steel cylinder where the water stop valve is installed, grasping the water stop valve's tightening nut, and rotating it. It is something.
この考案は、上記の問題点を解決するために、
レンチを次のように構成したのである。
In order to solve the above problems, this idea
The wrench was constructed as follows.
