Flow-straightening nozzle for rainwater tank

Abstract

To provide a flow-straightening nozzle capable of preventing foaming and scattering of a water surface in a rainwater tank caused by discharge of city water, and preventing cross-connection, in a rainwater tank that is replenished with city water by using a ball tap, without requiring a conduit or a cistern.SOLUTION: A flow-straightening nozzle is attached to a water discharge port of a faucet that replenishes city water by using a ball tap. The flow-straightening nozzle has a structure in which a plurality of tabular flow-straightening plates are radially arranged from an outer side toward an inner side at a mounting part of the water discharge port, and further, it is preferable that the tabular flow-straightening plates have a structure in which a central part is inclined downward relative to an outer side.SELECTED DRAWING: Figure 4
