The present application discloses a drain valve, comprising a valve body, a valve seat, and an overflow pipe. The valve seat includes a drainage channel. The overflow pipe includes a blocking element and a flow rate regulator. When the overflow pipe is in a raised state, the blocking element leaves a channel water inlet, the flow rate regulator is partially or completely located above the channel water inlet, and a water flow channel is formed between the flow rate regulator and the channel water inlet. An amount of water entering the drainage channel from the channel water inlet in unit time can be defined by the flow rate regulator, and thus a drainage flow rate can be controlled. If a user needs to change the drainage flow rate, the user only replaces different types of flow rate regulators, without replacing the whole drain valve to save costs.
