Water conservancy proportion charge device

The utility model belongs to the technical field of the scaling mixing apparatus of liquid medicine and water, specifically a water conservancy proportion charge device. It adds the medicine inefficiency to have solved ordinary medicine machine, degree of control is low, sometimes, need advance the ratio to the liquid medicine, need great work load, and the ratio in -process is not good to proportional control, cause the extravagant problem of liquid medicine, including water conservancy proportion dosing pump, the solenoid valve, the water gauge, Y type filter, hand stop valve and pvc pipeline, the pvc pipeline is connected with the water source, the pvc pipeline is equipped with the hand stop valve with the junction that the water source is connected, the pvc pipeline other end is connected with water conservancy proportion dosing pump, the solenoid valve is located to set up with water conservancy proportion dosing pump hookup location by the pvc pipeline, still be provided with water gauge and Y type filt
