The invention provides differential pressure amplified check valve equipment, which comprises a container, wherein openings are formed in the two ends of the container; an upper cover plate and a lower cover plate which are provided with water flow holes are arranged at the upper end and the lower end of the container respectively; an upper inverted filter is formed below the upper cover plate; a lower inverted filter is formed above the lower cover plate; a water rotator member and a differential pressure amplifier are arranged on the middle part of the container; side edge drainage channels positioned on both sides of the differential pressure amplifier, and a central drainage channel which is positioned on the upper part of the differential pressure amplifier and is communicated with the side-edge drainage channels are formed inside the water rotator member; the differential pressure amplifier is matched with the water rotator member to intensively draining water current in the side-edge drainage channels into the central drainage channel to perform opening-closing control. The differential pressure amplified check valve equipment has the advantages of no leakage under the actions of a large water faucet and a small water faucet, capability of meeting the requirement of high drainage flow, long running service life, easiness in installing and constructing, simple structure and capability of realizing scale production.
