A water meter with a check valve is provided to operate the check valve stably without an additional spring element, and to reduce noise, dust generated during return-flow prevention operation. A water meter with a check valve comprises a check valve sliding according to supply or blocking of water from a valve seed(1-2) provided inside an outlet of a valve body(1-1). The check valve includes a valve body formed of a head(21) blocking the valve seed and a guide rod(22), a water flow path(23a) provided at the outlet of the valve body, a slider(23) provided with a projection(23b) and a through-hole(23c). A projection(21a) is formed on one surface of the head and inserted to the valve seed. A plurality of grooves with cross type partition walls are formed on the other surface of the head. The guide rod is extended from the partition walls in a cross type. A pair of guide pieces are formed to face each other in the valve body to guide the head horizontally. |
