Drain valve base and water-saving drain valve
The invention discloses a drain valve base comprising a base body. A vertically-through drain hole is formed in the base body, and a water through hole used for communicating a toilet water tank withthe drain hole is formed in the upper portion of the side wall of the base body. An isolation base used for distributing water flowing through the drain hole is arranged on the lower portion in the drain hole, a first drainage channel penetrating up and down is formed in the isolation base, and a second drainage channel is defined between the outer wall of the isolation base and the inner wall ofthe drain hole. The invention further discloses a water-saving drain valve comprising the valve body and the drain valve base. According to the drain valve base, the isolation base used for shunting is arranged in the drain hole, the area ratio of the flowing water cross section of the first drainage channel to the flowing water cross section of the second drainage channel is controlled, so that water can be reasonably distributed into a spraying pipeline and a flushing pipeline of a closestool; and the optimal flushing effect is achieved while water is not wasted.
本发明公开了一种排水阀底座，包括底座本体，所述底座本体的内部设置有上下贯通的排水孔，底座本体的侧壁上部开设有用于连通马桶水箱和排水孔的通水孔。所述排水孔的内部下方设有一个用于对流经排水孔的水进行分流的隔离底座，隔离底座内部设置有上下贯通的第一排水通道，隔离底座外壁与排水孔内壁之间合围形成第二排水通道。本发明还公开了一种包括阀本体和上述排水阀底座的节水排水阀。本发明的排水阀底座在排水孔内设有用于分流的隔离底座，通过控制第一排水通道流水截面和第二排水通道流水截面的面积比，能够合理地把水量分派到马桶的喷射管道和冲洗管道内，在不浪费水的同时达到最佳冲洗效果。
