PURPOSE: A device for cleaning a pipe is provided to reduce a failure rate and a defect rate because an electronic control unit for controlling is not required and to maximize cleaning efficiency through medium air bubbles, vibration, and a cleaning solution. CONSTITUTION: A device for cleaning a pipe comprises a cleaning solution storage tank(10), a cleaning solution transfer pump(20), a compressor(50), a check valve(70), and a bubble shot valve(60). The bubble shot valve is installed between the compressor and the check valve. The bubble shot valve automatically opens and closes based on a predetermined pressure and discharges compressed air which is generated from the compressor to the check valve.
