The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: a large-diameter 45-degree elbow comprises an elbow body, a water inlet joint and a water outlet joint, wherein two ends of the elbow body are respectively and fixedly connected with a first flange plate, the two ends of the elbow body are respectively and fixedly connected with the water inlet joint and the water outlet joint through the first flange plate, the water inlet joint comprises a second flange plate, a first connecting pipe and a slow flow ring, the second flange plate is fixedly connected below the first flange plate at the lower end of the elbow body through bolts, the first connecting pipe is fixedly connected at the lower end of the second flange plate, the slow flow ring is fixedly connected at the upper end of the second flange plate, and the slow flow ring is connected in the lower port of the elbow body in an inserting manner; the water outlet joint comprises a third flange plate and a second connecting pipe, the third flange plate is fixedly connected to the first flange plate at the upper end of the elbow body through bolts, and the upper end of the third flange plate is fixedly connected with the second connecting pipe.
The outside lateral wall fixedly connected with of return bend body is along the strengthening rib of body axis setting.
The slow flow ring comprises a plurality of slow flow sheets which are arranged in a circular ring shape, and the slow flow ring is of a gradually reducing tubular structure.
A ring flange with between No. two ring flanges, a ring flange with the homogeneous phase is equipped with the seal groove ring from opposite directions between No. three ring flanges, just seal the intra-annular gomphosis of seal groove respectively and install the sealing rubber ring.
The inner pipe diameters of the water inlet joint and the water outlet joint are the same and are both smaller than the inner pipe diameter of the elbow body.
The utility model has the advantages that: this device can block partial rivers through the slow stream ring that sets up in the water supply connector to get into to rivers and play the first slow stream, because the interior pipe diameter of water supply connector and water outlet connector is less than the interior pipe diameter of return bend body, consequently rivers get into this internal back rivers of return bend and further obtain the buffering, thereby reach fine slow stream effect.
