[0004] With the improvement of people's living standards, many families use piped gas. When the piped gas enters the user's home, it is generally necessary to install an on-off valve and a gas meter. The inlet end of the on-off valve is used to connect with the main pipeline. The meter is connected to the gas outlet of the switch valve through a connecting pipe. At present, the connecting pipe generally includes an elbow, and both ends of the elbow are rotatable and connected with nuts. Through the internal thread on the nut, the two ends of the elbow can be connected Tighten them on the gas outlet of the on-off valve and the gas inlet of the gas meter respectively. Since the usual nuts can be disassembled at will with a universal wrench, people will disassemble and install the gas meter without permission, which will cause Illegal gas theft, gas leakage and damage to the gas meter, or turning the gas meter without permission to make the gas meter tilt, when the gas meter tilts at a certain angle, it will stop rotating to achieve the purpose of stealing gas

A gas meter and pipeline locking device comprises a switch valve and a connecting pipe. The intake end of the switch valve is connected with a main pipeline. The connecting pipe comprises a bend. Two ends of the bend are both rotatably connected with nus. The nuts at two ends of the bend are used for being tightened to an external thread of the exhaust end of the switch valve and an external thread of an intake hole of a gas meter. One end, connected with the exhaust end of the switch valve, of the bend is provided with a plum-flower pipe orifice. The bore wall of the exhaust end of the switch valve is provided with a plum-flower socket matching with the plum-flower pipe orifice. The nuts are anti-removal nuts. The gas meter and pipeline locking device has the advantage that the problem that gas stealing, gas leakage and gas meter damage caused by people mounting and demounting gas meters without permission and moving the gas meters without permission can be effectively avoided.
