PROJECTION MEMBER, PIPING MEMBER AND PIPING SYSTEM
To provide a projection member, a piping member, and a piping system that can improve a flow rate while enabling miniaturization.SOLUTION: A projection member 6-1 is disposed in a straight pipe (a vertical pipe 3) which is disposed downstream of a bent pipe 5-1 that changes a direction of a flow path and partially reduces a flow path cross-sectional area of the straight pipe (the vertical pipe 3). The projection member 6-1 includes: a main surface 61 which extends from a first end 6a directed to the upstream side toward a second end 6b directed to the downstream side, and is directed to the center side of the straight pipe (the vertical pipe 3) as viewed from a direction of a central axis C3 of the straight pipe (the vertical pipe 3); a first side surface 62 and a second side surface 63 which are located on both sides of the main surface 61 as viewed from the direction of the central axis C3 of the straight pipe (the vertical pipe 3); a first separation wall 64 which is located between the main surface 61 and the first side surface 62 to promote separation of a flow F1 along the main surface 61 and a flow F2 along the first side surface 62; and a second separation wall 65 which is located between the main surface 61 and the second side surface 63 to promote separation of the flow F1 along the main surface 61 and a flow F3 along the second side surface 63.SELECTED DRAWING: Figure 5
【課題】小型化を可能にしながら流量を向上できる、突起部材、配管部材及び配管システムを提供する。【解決手段】突起部材６－１は、流路の向きを変える屈曲管５－１の下流側に配置される直管（竪管３）内に配置されて直管（竪管３）の流路断面積を部分的に減少させる。突起部材６－１は、上流側に向けられる第１端６ａから下流側に向けられる第２端６ｂに向かって延び、直管（竪管３）の中心軸Ｃ３の方向から見て直管（竪管３）の中心側を向く主面６１と、直管（竪管３）の中心軸Ｃ３の方向から見て主面６１の両側にある第１側面６２及び第２側面６３と、主面６１と第１側面６２との間にあって主面６１に沿った流れＦ１と第１側面６２に沿った流れＦ２との分離を促進する第１分離壁６４と、主面６１と第２側面６３との間にあって主面６１に沿った流れＦ１と第２側面６３に沿った流れＦ３との分離を促進する第２分離壁６５と、を備える。【選択図】図５
