The invention discloses a residual pressure recovery device provided with integral rotary flow distribution plates. Symmetrically-arranged round fluid ducts, a symmetrically-arranged cylinder, and symmetrically-arranged flow distribution plates are adopted, so that eccentric shaking of the flow distribution plates and a central shaft is reduced, operation is stable, and the service life of the device is prolonged; the cylinder and flow distribution sleeves form a whole, so that the airtightness of the device is remarkably improved; labyrinth seals are arranged between the flow distribution plates and the flow distribution sleeves, so that mixing of high-pressure fluid and low-pressure fluid is effectively prevented; the outer rings of the flow distribution plates make contact with the flow distribution sleeves, so that radial fixing of the flow distribution plates is achieved, and the situation that the flow distribution plates shake when rotating, extra friction is generated, and consequentially the residual pressure recovery efficiency is affected is avoided; the labyrinth seals are arranged between the flow distribution plates and sealing covers, so that good airtightness is achieved, and fluid leakage is prevented; and the residual pressure recovery device provided with the integral rotary flow distribution plates has the advantages of being high in recovery efficiency, good in airtightness, stable in operation, simple in structure, convenient to install, low in cost and maintenance cost and the like.
