POSITIVE/NEGATIVE PRESSURE RELAXATION DEVICE
To provide the positive/negative pressure relaxation device that can save space in installation and can be installed in a vertical direction or a horizontal direction.SOLUTION: The positive/negative pressure relaxation device that is attached to a drain pipe to relieve a positive/negative pressure of the drain pipe comprises: a rubber cylinder 11 that is a cylindrical member of a hollow elastic body long in an axial direction, and an outer cylinder 10 of a casing member covering the rubber cylinder 11, wherein the rubber cylinder 11 contracts in a lateral direction to relieve a positive pressure when a pressure inside the drain pipe is positive, and the rubber cylinder 11 widens in the lateral direction to relieve a negative pressure when the pressure in the drain pipe is negative.SELECTED DRAWING: Figure 3
【課題】 設置にあたって省スペース化を図ることができ、垂直方向または水平方向への設置も可能な正負圧緩和装置を提供する。【解決手段】 排水配管に取り付けられて、排水配管の正圧および負圧を緩和する正負圧緩和装置であって、軸方向に長い中空の弾性体の筒状部材であるゴム筒１１と、ゴム筒１１を被覆するケーシング部材の外筒１０とを備え、排水配管内が正圧時にはゴム筒１１が側方向に収縮して正圧を緩和し、排水配管内が負圧時にはゴム筒１１が側方向に拡幅して負圧を緩和することを特徴とする。【選択図】図３
