<p>PROBLEM TO BE SOLVED: To easily rinse a pipeline in a short time. SOLUTION: One end 1a of the pipeline 1 to be rinsed is connected to a sucking pump 2 by interposing a transparent pipe 3 and a gas-liquid separation device 6 and the other end 1b is connected to a rinsing water supply hose 13 and an air supply valve 15. The inside of the pipeline 1 is made into highly negative pressure by operating the pump 2 and the rinsing water and the air are little by little supplied into the pipeline 1 while keeping the highly negative pressure. The inside of the pipeline 1 becomes such an atmosphere as if it is a rainstorm so that the rinsing water collides violently with the inside wall of the pipeline 1 to rinse the pipeline.</p> |
