The purpose of the present invention is to provide an apparatus for preventing boiler scale from being generated in a water pipe, wherein the apparatus has a closing valve to decrease the water passing cross-sectional area of the water pipe and has a bypass in the water pipe, and then allows the pressure difference between an inlet side and an outlet side of the bypass to be repeatedly generated and the swirl to be generated in the water pipe, thereby suppressing that boiler scales and foreign materials generated inside a water pipe are generated by swirl generated in the water pipe. In particular, other purpose of the present invention is to provide an apparatus for preventing boiler scale from being generated in a water pipe capable of simplifying the entire configuration of a removing apparatus by substantially using drinking water passing through the water pipe to remove boiler scales or foreign materials; and capable of reducing production costs. To achieve the purpose, according to the present invention, the apparatus for preventing boiler scale from being generated in a water pipe includes a closing valve (100) closing part of a first cross-section (A) in a water pipe (10); bypasses (200) connected to the water pipe (10) to be located on both sides of the closing valve (100); and a generation valve (210) generating swirl by being mounted on the bypass (200) and being periodically opened and closed. A first cross-section (A) of the water pipe (10) is the same as the sum of a second cross-section (A′) of the water pipe (10) which is decreased by the closing valve (100) and a third cross-section (A′′) of the bypass (200). |
