The specific implementation process is as follows: in the gas flowed into branch pipe main part 210 of gas supply small pipe 2 from gas supply main pipe 1, flow into gas-supply pipe 8 through branch pipe 220 again, because the design has first air vent 9 and the second air vent 10 with the inside intercommunication of second casing 420 on the gas-supply pipe 8, and shutoff board 810 has blocked gas-supply pipe 8, consequently, the gas can not directly get into in the intake pipe 310 of gas table 3 through gas-supply pipe 8, but in the intake pipe 310 of gas table 3 flows into according to following mode: the gas pipe 8 → the first vent hole 9 → the second housing 420 → the second vent hole 10 → the gas pipe 8 → the gas inlet pipe 310 of the gas meter 3, thereby realizing the gas intake.

When faults such as pipeline falling at the gas stove or gas leakage damage of a gas pipe (a pipeline from an air outlet pipe 320 of a gas meter 3 to the middle of the gas stove) in a user home occur, the flow sensor monitors the gas flow in the air outlet pipe 320 of the gas meter 3 in real time, therefore, when the gas circulates in the air outlet pipe 320 all the time and the gas flow data is abnormal, the chip 5 acquires the abnormal data from the flow sensor, the chip 5 immediately controls the electric valve 7 to be electrified and operated, the electric valve 7 seals and seals the second air vent 10, the gas inlet is cut off, the gas inlet is automatically stopped in an unmanned environment, the gas continuous leakage is avoided, and safety accidents are avoided.

When the gas meter 3 needs to be replaced, the shell 4 is separated from the gas meter 3, so that the components in the shell 4 and the shell 4 can be reserved when the gas meter 3 is replaced, the shell 4 and the components in the shell 4 are prevented from being replaced together, the waste of resources is avoided, and the replacement cost of a gas company and a user is reduced.

In addition, in this embodiment, because the chip 5 is installed in the first housing 410, and the electric valve 7 is installed in the second housing 420, when the first housing 410 is opened to overhaul the chip 5, the second housing 420 is not affected, that is, the first housing 410 is opened to overhaul the components in the first housing 410 on the premise that the gas pipe 8 is not closed by the manual valve 13, which is convenient to operate. In the present embodiment, since the head 171 of the antitheft screw 17 has a special structure, a special tool is required to rotate the antitheft screw 17, so that the right side wall of the second housing 420 can be detached, thereby exposing the inner space of the second housing 420. Therefore, the non-operator cannot normally detach the right side wall of the second housing 420, thereby preventing the loss of the motor-operated valve 7 and preventing the theft of the motor-operated valve 7.

Finally, in this embodiment, two adjacent gas supply branch pipes 2 threaded connection form the gas supply pipe together, compare in using three-way pipe and straight tube to link together and form the gas supply pipe, this embodiment has reduced the communicating point between the pipeline, has not only reduced staff's installation step, has still reduced the communicating point of gas supply pipe to reduce the possibility that the gas leaked from pipeline communicating point, improved the security of gas air feed.
