A drain valve for low-level water tank flushing includes a drain valve body, a low-level washing ring flushing device and a switch assembly. The switch assembly includes a switch element and a switch sheet. The switch element is connected to the switch sheet by using a lifting rod. When the switch element opens a sealing assembly of the drain valve body under the action of an external force, the switch sheet changes a channel between a water inlet and a water outlet from a small opening state to a big opening state.

An automatic protection device for an inlet valve or drain valve includes an inlet, an outlet, an on-off component, a control circuit, a control component, a water level inductor of the water tank and a water level inductor of the toilet. The water level inductor of the water tank and the water level inductor of the toilet are respectively connected to the control circuit, the control circuit drives the control component, the control component is connected to the on-off component to control the on-off component to open or close, thus connecting or disconnecting the inlet and the outlet. The automatic protection device will sound an alarm and automatically cut off the water supply when the drain valve fails to discharge, or when the toilet is plugged up and is unable to drain water.
