初始状态下，排水阀110的止水组件111与第一入水口131密封配合，水箱100中的水处于全满水位。排水时，通过操作排水阀110，使止水组件111与第一入水口131分离配合，水箱100中的水通过该第一入水口131进入排水通道130，并分别在第一出水口132和第二出水口133产生分流，使一部分水从排水通道130的导流壁135上的第一出水口132进入边缘通道210，另一部分水从第二出水口133进入喷射通道。
需要说明的是，排水通道130的具体结构可根据实际需要进行设计为不同的形状，第一出水口132的开设位置主要与座体200的边缘通道210的结构和位置相匹配。
如图1、图5和图6所示的实施例四以及图1、图7和图8所示的实施例五，实施例四和五提供一种双套管式马桶排水装置，包括水箱100及座体200，本实施例的水箱100装接在座体200上方，水箱 100内设有排水阀110。座体200内设有用于洗刷马桶便池内壁的边缘通道210和用于对马桶便池底部喷射的喷射通道(未图示)，排水阀110的安装座120固定设置在水箱100的底壁上。该安装座120具有一排水通道130，该排水通道130由外套管125和内套管124相互套接形成。该排水通道130从上至下依次设有相互连通的第一入水口131、第一出水口132、第二出水口133。外套管125设有的第一出水口132，内套管124设有的第二出水口133。第一入水口131与水箱内腔相连通并与排水阀110的止水组件111密封配合或者分离配合。第一出水口132与喷射通道和边缘通道210的二者之一相连通，第二出水口133与喷射通道和边缘通道210的二者之另一相连通。本实施例中，优选为第一出水口132与边缘通道210相连通，第二出水口133与喷射通道相连通。
