Water-gas unit with pressure dividing function

The invention relates to a water-gas unit with a pressure-dividing function, which comprises an electric cabinet, a gas path system, a water inlet path and a water return path which are arranged on a base, the gas path system comprises a gas source triple piece and is also provided with a pressure-dividing loop, and the pressure-dividing loop is communicated with the water inlet path and the water return path through a water inlet path pressure-dividing ball valve; a water inlet three-way joint, a water inlet path Y-shaped internal thread filter and a water fluid valve in the water inlet path are mounted and communicated together through a water inlet path water pipe; a return water three-way joint, a water flow sensor, a return water path water horizontal check valve and a return water path Y-shaped internal thread filter in the return water path are mounted and communicated together from right to left through a return water path water pipe; and the partial pressure loop is formed by communicating a water in
