Detailed Description

In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1-5, a water supply copper insert elbow with a round pipe bend comprises a plastic shell 1 and a copper insert 2, wherein the copper insert 2 is embedded on the inner wall of one end of the plastic shell 1, and the inner wall of the other end of the plastic shell 1 is in a round pipe bend shape.

Specifically, the round tube bending shape is arranged according to the water flowing direction, so that when water flows through the round tube bending direction, all the sections are completely consistent and smooth, the effect of reducing the water flow resistance is achieved, the flow is increased, and the energy consumption is reduced in the power water conveying process.

As shown in fig. 4, an annular anti-leakage block 4 is arranged on the outer wall of the copper insert 2 propped against one end of the plastic shell 1, an annular anti-leakage groove 5 corresponding to the annular anti-leakage block 4 is arranged at one end of the plastic shell 1, an internal thread 6 is arranged on the inner wall of the copper insert 2, and an anti-rotation clamping block 3 is arranged at the right end of the copper insert 2.

Specifically, annular antiseep piece 4 and annular antiseep groove 5 closely interlock reach sealed leak-stopping's effect, and copper inserts 2 right-hand member is equipped with prevents changeing fixture block 3, prevents copper inserts 2 to screw up the screw thread in the installation and produce rotatory not hard up, finally firmly combines plastics and metal inserts, prevents changeing again leak-stopping.
