Description

Water pipe cleaning system using high-speed water flow and pulsation and water pipe cleaning method using the same {WATER PIPE CLEANING SYSTEM AND WATER PIPE CLEANING METHOD USING THE SAME}

The present invention relates to a water pipe cleaning system using high-speed water flow and pulsation and a water pipe cleaning method using the same.

When water pipes are used for a long time after installation, various foreign substances accumulate on the inner walls of the water pipes, so it is necessary to clean the water pipes to remove and discharge them.

One of the conventional water pipe cleaning methods is a flushing method that injects high-pressure air or nitrogen.

However, when using high-pressure gas, there were problems such as noise caused by gas expansion and water pipes vibrating due to water impact. As high-pressure air or nitrogen moves along the water pipes, it expands rapidly and the pressure decreases. As a result, the cleaning power rapidly decreases, causing a problem in which the cleaning effect decreases toward the end of the water pipe.

In addition, when high-pressure gas is used in this way, the water valve on the upstream side of the water pipe is opened to a certain extent to allow tap water to flow to be used as washing water. If the gas pressure is higher than the pressure of the washing water on the upstream side of the water pipe, it flows back and removes foreign substances from the water pipe. There was a problem that accidents and resulting civil complaints often occurred among tap water users. Additionally, there was a problem that water usage increased when the cleaning operation using high-pressure gas was repeated several times.

For example, the opening rate of the water valve 410 may be controlled by the water valve control unit 420.

In this way, the flow speed of the washing water must be 0.9 m/sec or more, that is, a high-speed water flow must be formed to smoothly wash foreign substances in the water pipe 20.

Additionally, in the washing operation stage, the opening rate of the overflow valve 410 may be controlled so that the flow speed of the washing water is 0.9 m/sec or more and then controlled in a pulsation wave-type cycle. As a result, the washing water is supplied to the water pipe 20 in the form of a high-speed water flow and pulsation flow, so that the washing operation can be performed.

Next, in the washing end step, as shown in FIG. 5, the pump 310 is stopped, the first control valve 320 is closed, and the first water valve 21 and the discharge valve 610 are opened. The washing water filled in the water pipe 20 can be discharged to the discharge line 600.

Meanwhile, the washing water or residual water filling the supply line 300 is separated from the first connection part 110 with the first connection part 110 and the first control valve 320 closed, and then connected to the sewer pipe. , it can be discharged by connecting to a rainwater pipe, river, etc. and opening the first control valve 320.

However, it is not necessarily limited to this, and if the quality of the washing water is not sufficient to be used as tap water through filtering at the end of the washing operation, the washing water may be returned to the water pipe 20.

For example, with the first control valve 320 and the second water valve 22 open and the second control valve 520 closed, the pump 310 is operated to return the washing water to the water pipe 20. can send.

Next, in the system separation step, the first connection 110 and the second connection 120 are closed and the supply line 300 and the return line 500 are disconnected from the first connection 110 and the second connection 120. It can be separated, and the cleaning work can be completed by opening the first water valve 21 and the second water valve 22.
