Stagnation container and gas meter detection device

The stagnation container comprises a container barrel, a steady flow piston plate and a power mechanism, a cavity is formed in the steady flow piston plate, a plurality of through holes communicated with the cavity are evenly distributed in one side of the steady flow piston plate, a movable blind plate capable of covering an opening of the inner cavity is arranged on the other side of the steady flow piston plate, and the power mechanism is connected with the steady flow piston plate. An air inlet pipe is arranged on the movable blind plate, and the hole diameter of the through hole is gradually increased from the center to the outside. The through holes are uniformly formed in the flow stabilizing piston plate, and the hole diameters of the through holes are gradually increased from the center to the outside, so that uniform passing of gas is realized, the stability of gas flow is improved, and the detection accuracy of the detection device is improved. 本发明涉及一种滞止容器以及燃气表检测装置，包括容器筒体、稳流活塞板和动力机构，所述稳流活塞板内具有空腔，稳流
