The invention relates to a differential pressure integrated microflow metering compensation valve which is used in matching with a fluid metering device, can measure minute flow rate and improve the sensitivity of the metering device. The compensation valve is characterized in that a rubber differential pressure integrating sleeve is arranged on the inner wall of the entering end of the valve body; the rubber differential pressure integrating sleeve is provided with a front tooth ring and a rear tooth ring, the cross section of which is in tooth shape; the front tooth ring and the rear tooth ring are respectively matched with a valve plug which moves into the rubber differential pressure integrating sleeve to form elastic dynamic transition sealing. The compensation valve of the inventionmainly uses the elastic deformation of the rear tooth ring of the rubber differential pressure integrating sleeve to improve the differential pressure of the two cavities of the valve, thus magnifying surge phenomenon in the starting process of the valve, generating a transient pulsed water pressure to lead a metering mechanism to rotate and count. The compensation valve of the invention can be used in matching with any meter and improve the metering precision, has one-way non-return function, strong adaptability to water quality, favorable anti-creeping performance, compact and simple structure, good reliability and long service life.
