The present application belongs to the technical field of turbine flowmeter, and discloses a double turbine flowmeter, which comprises a flowmeter, a detection flow channel is arranged in the flowmeter; a first sealing step and a second sealing step are arranged in the detection flow channel, and a backflow channel is communicated between the first sealing step and the second sealing step; a quick connecting assembly is used for mounting the flowmeter to a pipeline; the quick connecting assembly comprises a fixing assembly and a sealing ring which is sealed between the outer wall of the pipeline and the inner wall of the detection flow channel, the fixing assembly is configured to make the pipeline and the sealing ring abut to the first sealing step and the second sealing step respectively; the sealing ring comprises a first sealing ring and a second sealing ring which are mutually abutted along the axial direction through guide inclined surfaces, when fluid impacts the sealing ring axially through the backflow channel, part of the axial impact force is decomposed into a radial inner component force acting on the first sealing ring and a radial outer component force acting on the second sealing ring through the guide inclined surfaces.

This utility model relates to the field of hydraulic transmission equipment technology, specifically to a composite dual-turbine hydraulic torque converter, comprising a dual-turbine hydraulic torque converter body, an input shaft disposed at the input end of the dual-turbine hydraulic torque converter body, and an output shaft disposed at the output end of the dual-turbine hydraulic torque converter body. Both the input and output shafts are fitted with sealing sleeves, which are detachably mounted on the dual-turbine hydraulic torque converter body. A rigid clamping ring is disposed inside the sealing sleeve and fitted onto the corresponding shaft. An inner sealing ring is disposed between the rigid clamping ring and the front cylindrical body of the sealing sleeve. An inner bushing is disposed on the rear side of the rigid clamping ring. Inner fitting gaskets are disposed on both the inner and outer end faces of the inner bushing. The inner fitting gasket on the inner side fits onto the corresponding shaft, and the inner fitting gasket on the outer end face abuts against the rear side of the rigid clamping ring. This utility model has good sealing performance, achieving the effect of improving sealing reliability and ensuring stable equipment operation.
