Anti-backflow joint for double-riser-pipe drainage system and double-riser-pipe drainage system
The invention provides an anti-backflow joint for a double-riser-pipe drainage system and the double-riser-pipe drainage system. The anti-backflow joint comprises a first connecting pipe, a second connecting pipe, a third connecting pipe and an anti-backflow part, wherein the first connecting pipe is suitable for being in communication with a drainage pipe; a first through hole is formed in the first connecting pipe; the second connecting pipe is suitable for being in communication with a vent pipe; a second through hole is formed in the first connecting pipe; one end of the third connecting pipe is in communication with the first through hole; the second end of the first connecting pipe is in communication with the second through hole; the anti-backflow part is arranged at the first through hole and/or the second through hole; and the anti-backflow part is used for shielding a part of the first through hole and/or the second through hole to prevent water in the drainage pipe from flowing into the vent pipe. Through arrangement of the anti-backflow part, the drainage pipe is prevented from entering the vent pipe during drainage, so that the water discharge of the double-riser-pipedrainage system is ensured.
本发明提供了一种双立管排水系统用防返流接头以及双立管排水系统。防返流接头包括：第一连接管，第一连接管适于与排水管相连通，第一连接管上设有第一通孔；第二连接管，第二连接管适于与通气管相连通，第一连接管上设有第二通孔；第三连接管，第三连接管的一端与第一通孔相连通，第一连接管的第二端与第二通孔相连通；防返流件，防返流件设置于第一通孔和/或第二通孔处，防返流件用于遮挡部分第一通孔和/或第二通孔以阻挡排水管内的水流入通气管。通过设置防返流件，以避免排水管在排水时会进入通气管内，从而保证双立管排水系统的排水量。
