[0050] The torsion outer ring 1 is ring-shaped, and the front end of the inner wall of the torsion outer ring 1 is provided with a first protruding ring 11 and a second protruding ring 12 in sequence from front to back, and an annular cavity 13 is also formed inside the torsion outer ring 1 , the annular chamber 13 is evenly distributed in the circumferential direction along the front and rear direction with a perforated baffle 13a, the perforated baffle 13a is provided with a baffle through hole, and the annular chamber 13 is evenly distributed circumferentially along the rear half There are radial insertion holes 14 corresponding to the baffle through holes of the perforated baffle 13a one by one, and an inner ring 14a of the insertion hole is formed at the connection between the radial insertion hole 14 and the annular chamber 13;
[0051] Further, the outer circumference of the torsion outer ring 1 is formed into a hexagonal shape.
[0052] Thanks to the improvement above,...

When pipeline gas enters the house of a user, a switch valve and a gas meter are generally installed, the gas inlet end of the switch valve is used for being connected with a main pipeline, and the gas meter is connected and communicated with the gas outlet end of the switch valve through a connecting pipe. At present, the connecting pipe generally comprises a bent pipe, the two ends of the bent pipe are rotationally connected with nuts, the two ends of the bent pipe can be screwed at the gas outlet end of the switch valve and the gas inlet end of the gas meter through the internal threads onthe nuts, and due to the fact that the common nut can be disassembled at will through a universal wrench, people can disassemble and assemble the gas meter privately, and the phenomena of illegal gasstealing, gas leakage and gas meter damage can be caused. According to the method for connecting the gas meter and the gas pipeline, a user can be effectively prevented from disassembling the gas meter and stealing gas at will, a gas meter disassembly prevention connector is used, and the connector comprises a torsion outer ring, an internal thread ring, a reversing device, a sealing rubber ring and a tower-shaped connector.
Description
technical field [0001] The invention relates to the technical field of gas meters, in particular to a method for connecting a gas meter and a gas pipeline. Background technique [0002] 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 per...
