FIELD: water valves.

SUBSTANCE: present invention provides an integrated water valve, a water supply system and a working machine, which include a hydraulic control water valve, a hydraulic control valve and an adapter block, and the adapter block is connected between the hydraulic control water valve and the hydraulic control valve, so that the hydraulic control water valve, adapter block and hydraulic control valve are connected as one unit. The hydraulic control water valve is equipped with a control oil hole. The hydraulic control valve is provided with a first oil inlet port, a first oil return port, a first service oil port, and a second service oil port. At least an oil inlet port, an oil return port, and a first operating port are located in the adapter block. The control oil hole communicates with the first working oil hole through the first working channel. The first oil inlet port communicates with an external control oil source through the oil inlet port, and the first oil return port communicates with the hydraulic oil tank through the oil return port. For the integrated water valve proposed in the present invention, an adapter block is used to replace the pipeline used to connect the hydraulic control valve and the hydraulic water control valve.

EFFECT: structure is more compact, the connection is simpler and faster, and installation space is saved.
