<P>PROBLEM TO BE SOLVED: To provide a piping member for discharging drainage preventing functional failure of a heat source machine due to clogging at a downstream side of a neutralizer without increasing a manufacturing cost. <P>SOLUTION: The piping member 1 for discharging drainage, has a side opening 37 for communicating the inside and outside of a cylindrical body, and an inner wall auxiliary wall 36 covering the side opening 37 from an inner wall side of the cylindrical body. A discharge auxiliary space 40 is defined between the side opening 37 and the inner wall auxiliary wall 36 in a state that the discharge auxiliary space 40 is closed at an upstream side of the cylindrical body and communicated with the side opening 37 at a downstream side. When the drainage accumulates near the inner wall auxiliary wall 36, the drainage can be discharged from the side opening 37. <P>COPYRIGHT: (C)2011,JPO&INPIT |
