The utility model relates to flowmeter device technical field discloses a kind of swirl flowmeters, including measuring tube, the both ends of measuring tube are fixedly connected with flange, the outside of measuring tube is provided with steady flow component, the inside fixedly connected with racemizer in the one end of measuring tube far from steady flow component, the inside of measuring tube is provided with fairing, the inside of fairing is provided with bevel gear one, the outside of bevel gear one is all engaged with bevel gear two in four corners, the outside fixedly connected with connecting shaft of bevel gear two. In the utility model, by the cooperation of knob, connecting shaft, bevel gear two and bevel gear one, when measuring low flow gas, the flow condition of gas in pipeline can be adjusted by adjusting the force area of fan blade, to ensure the measurement accuracy of flowmeter, and the quick method of knob adjustment makes the device can be quickly adjusted when measuring different gas, improves the measurement accuracy.

The present invention relates to an apparatus for reducing greenhouse gas emission in a vessel cooperated with exhaust gas recirculation (EGR), and a vessel including the same, in which NOx generation is reduced, which is the original purpose of EGR, while maintaining existing EGR, SOx as well as CO2, which is the representative greenhouse gas, are absorbed and converted into materials that do not affect environments, and the materials are discharged or stored as useful materials, thereby preventing corrosion of an engine and improving combustion efficiency.

The invention belongs to the technical field of mechanical part testing, and provides a gearbox operating valve test bed. A gearbox operating valve test bed comprises a flow control oil way, a tested valve body and an oil supply way, the flow control oil way is provided with a first outlet end and a second outlet end, the first outlet end is the tested valve body, the second outlet end is the oil supply way, the flow control oil way comprises a first valve body and a control valve block, and flow meters are arranged at the two ends of the first valve body. The flow meters comprise the first flow meter and the second flow meter, the first flow meter is located on the side, close to the first valve body, of the tested valve body, and the second flow meter is located between the control valve block and the first valve body. The real-time output pressure of the oil supply path is monitored, so that an oil path element is protected, and the first valve body and the subsequent detected valve body are prevented from being damaged; and measuring the flow of the input end of the measured valve body by adopting a first flow meter to obtain the flow feedback information of the working condition of the measured valve body.

The present invention discloses a novel hinged sea ambush energy dissipation structure, which relates to the technical field of water conservancy engineering, including a crushed stone cushion layer, an energy dissipation strip, an articulated steel bar, a water diversion and return flow component, a supporting diversion column, a limiting fixed tooth, and a water venting hole. The surface of the crushed stone cushion layer is evenly and staggeredly arranged with multiple groups of mutually cooperating energy dissipation strips. The present invention improves the traditional sea ambush structure type, not only can realize the accurate elimination of residual energy, but also can solve the problem of the structural transition zone between the building and the riverbed that is rigid and flexible. The strip, wheel sequence and skip bin casting construction method saves costs compared with concrete blocks and meets the requirements of saving stone resources. By evenly and staggered splicing multiple groups of energy dissipation strips in a certain order, the upper surfaces of multiple groups of energy dissipation strips are all inclined, so that a drop-type micro-fall structure is formed between each group of energy dissipation strips, and the energy dissipation strips are separated in a way of breaking the whole into parts and hinged into an integral sea ambush through articulated steel bars.
