The invention discloses a water-saving valve for a toilet tank. The water-saving valve comprises a water cup internally provided with a water tank, a buoy arranged in the water tank in an up-down floating mode, a lifting rod used for opening a water outlet of the water tank, a water inlet pipeline, a back pressure valve used for opening and closing the water inlet pipeline and a water inlet swing rod used for opening and closing a pressure relief hole, wherein a weep hole is formed in the bottom of the water cup, the back pressure valve comprises a water stop rubber mat and an upper cover, the water stop rubber mat is located above the water inlet pipeline, the upper cover is provided with the pressure relief hole, and the end of the water inlet swing rod is connected with the buoy. When the buoy falls down due to insufficient buoyancy, the water inlet swing rod is pulled to swing, so the water inlet swing rod opens the pressure relief hole, and meanwhile, the lifting rod falls down to close the water outlet of the water tank. Water inflow and water outflow are controlled by the same buoy, so the number of spare and accessory parts is reduced, and the valve has the advantage of being simple and compact in structure.
本发明公开了一种马桶水箱节水阀，马桶水箱节水阀，包括内部设置水槽的水杯、可上下浮动的置于所述水槽内的浮筒及用于打开水箱出水口的提拉杆，所述水杯底部设有漏水孔，还包括进水管道以及用于开闭所述进水管道的背压阀，所述背压阀包括止水胶垫和上盖，所述止水胶垫位于所述进水管道上方，所述上盖设有泄压孔，还包括用于开闭所述泄压孔的进水摆杆，所述进水摆杆端部与所述浮筒连接，当所述浮筒因浮力不足而落下时便拉动所述进水摆杆发生摆动，使所述进水摆杆打开所述泄压孔，同时所述提拉杆落下关闭水箱出水口。进水和排水由同一个浮筒进行控制，节省了零配件的数量，具有结构简单、紧凑的优点。
