The viewing hole and maintenance hole are sealed by a sealing cover.

[0009] As described above, an electric valve is installed between the valve before the meter and the gas meter; a gas alarm is installed indoors; the gas alarm is electrically connected to the electric valve; if a gas leak occurs indoors, the gas alarm will emit an audible and visual alarm and simultaneously close the electric valve to prevent the gas leak.

[0010] As described above, a controller is installed near the gas stove, and the controller is electrically connected to the gas alarm; the controller sends a switch command to the gas alarm, and the gas alarm controls the opening and closing of the electric valve.

[0011] As described above, a controller is installed near the gas stove, and the controller is electrically connected to the electric valve; the controller sends switching commands to the electric valve to control the opening and closing of the electric valve.

[0012] As described above, a controller is installed near the gas stove, and an electric shut-off valve is installed between the gas meter and the valve in front of the stove. The controller is electrically connected to the electric shut-off valve; the controller sends a switch command to the electric shut-off valve to control the opening and closing of the electric shut-off valve.

[0013] As mentioned earlier, the controller is integrated with the control panel of the gas stove, so that the stove valve on the gas stove is synchronized with the controlled electric valve or electric shut-off valve; when the stove valve is opened, the electric valve or electric shut-off valve is also opened synchronously; when the stove valve is closed, the electric valve or electric shut-off valve is also opened and closed synchronously.

[0014] As described above, a gas alarm I is installed in the chamber, and the gas alarm I is electrically connected to the electric valve; if a gas leak occurs inside the chamber, the gas alarm I will emit an audible and visual alarm and automatically close the electric valve.

[0015] The beneficial effects of this invention are: its compact design saves indoor space and reduces material consumption. At the same time, it facilitates gas leak prevention and aesthetic installation, resulting in a more beautiful and harmonious indoor environment and safer gas usage. Attached Figure Description

Detailed Implementation

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0021] like Figure 1 As shown in this embodiment, a gas meter valve and pipe assembly system is provided. The gas meter 2 is fixed on the indoor main pipe 1. The gas meter 2 is equipped with a pre-meter valve 3 at its gas inlet, and the pre-meter valve 3 is connected to the main pipe 1. The gas meter 2 is connected to the stove valve 5 through a branch pipe 4, and the stove valve 5 is connected to the gas stove 6 through the branch pipe 4.

[0022] In this embodiment, the gas meter 2, the valve before the meter 3, the valve before the stove 5, and the branch pipe 4 are assembled with the main pipe 1, which saves indoor space and also saves consumables; it is also more conducive to the assembly of gas pipeline leak prevention process.

[0023] like Figure 2 As shown in the figure, this embodiment of the gas meter valve and auxiliary pipe assembly system anti-leakage process assembly implementation method includes a main pipe 1, a gas meter 2, a branch pipe 4, and a sealing decorative profile 7 on the outside of the valve. The sealing decorative profile 7 and the wall 9 form a cavity 8. A guide pipe 10 is installed through the wall 9 at the top of the cavity 8 and is connected to the outside. The branch pipe 4 passes through the sealing decorative profile 7 and exits the cavity 8 to connect with the gas stove 6. A protective sleeve 11 is installed on the exiting branch pipe 4. One end of the protective sleeve 11 is connected to the gas stove 6 and the end of the branch pipe 4 for sealing, and the other end is connected to the cavity 8.

[0024] In this embodiment, after being treated with leak-proof technology, the main pipeline 1, branch pipeline 4, gas meter 2, meter valve 3, stove valve 5, and various valves are all shielded from the indoor environment. Even if the gas pipeline and valves leak, the overflowing gas will not enter the room, but will only be discharged outdoors through the guide pipe 10 and dispersed into the atmosphere. Outdoor air circulation is fast, and the gas will generally not reach the range of deflagration ratio. Furthermore, there is no open flame outdoors, so it will not cause deflagration.

[0025] In this embodiment, the sealing decorative profile 7 is provided with a viewing hole 12 and a maintenance hole 13. The viewing hole 12 allows observation of the operation of the gas meter 2 and valves; the maintenance hole 13 allows maintenance and inspection of the gas pipeline, gas meter 2, and valves in the chamber; the viewing hole 12 and the maintenance hole 13 are sealed by the sealing cover plate 14.

[0026] like Figure 1 , 2 As shown in this embodiment, in a gas meter valve and pipe assembly system, an electric valve 15 is installed between the pre-meter valve 3 and the gas meter 2; a gas alarm 16 is installed indoors; the gas alarm 16 is electrically connected to the electric valve 15; if a gas leak occurs indoors, the gas alarm 16 will issue an audible and visual alarm and simultaneously close the electric valve 15 to prevent gas leakage.

[0027] As shown in the above embodiment, if the gas stove 6 leaks gas, the leaked gas will be detected by the gas alarm 16, which will issue an audible and visual alarm and simultaneously close the electric valve 15 in the chamber 8. After the electric valve 15 is closed, the gas supply is cut off at the source, thus preventing gas leaks caused by the gas stove 6.

[0028] In this embodiment, a controller 17 is installed near the gas stove 6, and the controller 17 is electrically connected to the gas alarm 16; the controller 17 sends a switch command to the gas alarm 16, and the gas alarm 16 controls the opening and closing of the electric valve 15.

[0029] In this embodiment, a controller 17 is installed near the gas stove 6. The controller 17 is electrically connected to the electric valve 15. The controller 17 sends a switch command to the electric valve 15 to control the opening and closing of the electric valve 15.

[0030] In this embodiment, a controller 17 is installed near the gas stove 6, and an electric shut-off valve 18 is installed between the gas meter 2 and the valve 5 in front of the stove. The controller 17 is electrically connected to the electric shut-off valve 18. The controller 17 sends a switch command to the electric shut-off valve 18 to control the opening and closing of the electric shut-off valve 18.

[0031] As shown in the three embodiments above, after the gas stove 6 is used up, the stove valve 20 is closed, and the electric valve 15 or electric shut-off valve 18 in the chamber 8 is closed by the controller 17. In this way, the two valves simultaneously cut off the gas pipeline, making the use of gas safer.

[0032] In this embodiment, the controller 17 is combined with the control panel 19 of the gas stove 6, so that the stove valve 20 on the gas stove 6 is synchronized with the controlled electric valve 15 or electric shut-off valve 18; when the stove valve 20 is opened, the electric valve 15 or electric shut-off valve 18 is also opened synchronously; when the stove valve 20 is closed, the electric valve 15 or electric shut-off valve 18 is also opened and closed synchronously.

[0033] As shown in the above embodiment, the combination of the control panel 19 and the controller 17 of the gas stove 6 makes the system more advanced. After using the gas stove 6, simply close the stove valve 20. The stove valve 20 will then activate the electric valve 15 or the electric shut-off valve 18 in the chamber 8, achieving the purpose of simultaneously shutting off the gas pipeline with both valves. When using the gas stove 6, simply open the stove valve 20, and the stove valve 20 will activate the electric valve 15 or the electric shut-off valve 18 to open simultaneously.

[0034] In this embodiment, a gas alarm I21 is installed in the chamber 8, and the gas alarm I21 is electrically connected to the electric valve 15. If a gas leak occurs inside the chamber 8, the gas alarm I21 will emit an audible and visual alarm and actively close the electric valve 15.

[0035] As shown in the above embodiment, the gas alarm I21 can detect gas leaks in chamber 8. If an alarm is issued indicating a gas leak in chamber 8, the gas user is prompted to report the leak to the gas company.
