| titleOfInvention | Water-saving water supply and drainage device for rice |
| abstract | The utility model discloses a water-saving water supply and drainage device for rice, which comprises a water supply and drainage pipeline, a connecting piece main body, a first fixed end, a second fixed end and a cushioning component, wherein the first fixed end and the second fixed end are respectively arranged at the two ends of the connecting piece main body; the hydraulic piston is used at the joint of the water supply and drainage pipeline for buffering and damping, impact on the pipeline caused by a water hammer is eliminated through floating of the piston, a good protection effect is achieved while inconvenience in installation and low economic benefit of the traditional air pressure damper are solved, and the applicability and convenience are remarkably improved. |
