[0006] As a preferred implementation scheme of a wet ball valve water meter, specifically, the number of the first sealing rings is 2, so that a double seal is formed between the valve stem and the pipe section, and the sealing effect is greatly enhanced.

[0007] As a preferred embodiment of a wet ball valve water meter, specifically, the housing is provided with an assembly column, the assembly column is hollow for the output rod to extend out, and the bottom of the assembly column is provided with an assembly groove for assembly with the top of the assembly seat, so that the housing can be tightly assembled with the pipe section.

[0008] As a preferred implementation scheme of a wet ball valve water meter, specifically, the portion of the output rod corresponding to the inner wall of the assembly column is equipped with a second sealing ring to prevent debris from entering the control valve through the gap between the assembly column and the output rod.

[0009] As a preferred implementation scheme of a wet ball valve water meter, specifically, the number of the second sealing rings is 2, so that a double seal is formed between the output rod and the assembly column, and the sealing effect is greatly enhanced.

[0010] As a preferred implementation scheme of a wet ball valve water meter, specifically, the meter body is equipped with an NB-IOT remote transmission module to achieve long-distance communication and facilitate timely reporting of flow data.

[0011] As a preferred implementation scheme of a wet ball valve water meter, specifically, the control valve is a wireless valve, which facilitates remote switching of the control valve.

[0012] As a preferred implementation scheme of a wet ball valve water meter, specifically, the meter body adopts non-magnetic sampling, which is beneficial to enhancing the magnetic anti-interference ability and has high sampling accuracy.
