[Prior Art] Conventionally, when repairing gas piping plugs, there are many cases in which the plug cannot be rotated to open and close due to grease sticking. It was like that. After closing the valve on the piping upstream of the Kotsuk to stop the gas supply, disassemble the Kotsuk, take out the Kotsuk's stopper, clean the Kotsuk's stopper and the sliding surfaces between it and the stopper's main body, and apply new grease again. They were applying it and reassembling the stopper.

Furthermore, if there is no valve on the upstream side of the gas pipe, it is very difficult to prevent instantaneous leakage of gas outside the pipe when repairing the gas pipe.

[Problems to be solved by the invention] Conventionally, when repairing a gas pipe, there was a problem in which the gas supply had to be stopped by closing the valve on the piping upstream of the pipe. If there is no shutoff valve, there is a problem in that the gas pipe cannot be repaired without gas leaking out of the gas pipe.

The purpose of the present invention is to provide a bag for repairing gas pipes that can be easily installed on gas pipes and with gas flowing through the gas pipe without gas leakage. be.
