The invention relates to a multifunctional water pump valve which comprises an exhaust valve and a safety valve, wherein the exhaust valve is provided with a water inlet pipe, a water outlet pipe and an air exhaust pipe; the safety valve is provided with a water inlet end, a pressure relief end and a water outlet end; the exhaust valve and the safety valve are connected into a whole; the water outlet pipe of the exhaust pipe is connected with the water inlet end of the safety valve; and the interior of the water outlet pipe or the water inlet end is provided with a one-way valve. When the exhaust valve and the safety valve are combined and connected between a water pump and a boiler of a steam electric ironer and the like, the air in a pump casing or a pipeline can be automatically exhausted in the water pumping process of the water pump, and the high-pressure water flow can be generated in short time to supply water to the boiler. The exhaust valve and the safety valve are provided with one one-way valve. When a certain pressure is generated during water pumping, the one-way valve is opened to inject water into the boiler. When the boiler is changed into a cold state from a heat state, and the negative pressure is generated, the one-way valve can prevent the boiler from absorbing water from the water pump and the pipeline, thereby ensuring that the water quantity in the boiler is stable. When the pressure in the boiler exceeds the specified requirement, the pressure can be safely relieved through the self safety valve.
