Novel cold-resistant and anti-freezing water meter

The utility model relates to the technical field of water meters, in particular to a novel cold-resistant and anti-freezing water meter which comprises a water meter shell, a first heat preservation layer is fixedly connected to the outer portion of the water meter shell, a heat insulation pad is fixedly connected to the bottom of a cover plate, and a rock wool board is fixedly connected to the outer portion of a dial plate. A graphene heating wire is laid in the second warm-keeping layer, and an anti-freezing solution is arranged in the liquid storage cavity groove. According to the novel cold-resistant and anti-freezing water meter, the whole water meter shell structure is protected through the first heat preservation layer, then the second heat preservation layers are arranged at the water inlet end and the water outlet end, the graphene heating wires are laid and wound in the second heat preservation layers, and the graphene heating wires heat the outer portions of the water inlet end and the water outlet
