The invention discloses a pot-type pipe network differential pressure quantity compensation flow stabilization water supply device. The device is mainly composed of a flow control valve, a flow stabilization compensation tank, a negative pressure eliminator, a first water pump, a second water pump, an air compensation tank, a flow detecting device and a control cabinet. The flow stabilization compensation tank comprises a three-cavity horizontal structure composed of a flow stabilization cavity, a water storage cavity and an air-water energy storage cavity; the flow stabilization cavity and the air-water energy storage cavity are located at the two ends of the flow stabilization compensation tank respectively, and the water storage cavity is connected with a water distribution pipe through a connecting pipe with a first solenoid valve; and a differential pressure compensation pipe is further arranged between the first solenoid valve and a water storage opening so as to be connected with the water distribution pipe. The pot-type pipe network differential pressure quantity compensation flow stabilization water supply device has the beneficial effects of being compact in structure, small in occupied land, convenient to install and maintain, sanitary in water quality and the like; in addition, differential pressure compensation adjustment on the insufficient tap water inlet amount can be achieved through the water storage cavity, so that the adjusting volume is increased, and the water supply safety is improved; meanwhile, the flow-flow pump stopping pressure maintaining water supply energy saving can be achieved through the air-water energy storage cavity, so that energy-saving points are improved; and the service life is prolonged.
