Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1 to 4, according to an embodiment of the present invention, a reducing pipe includes: the pipe body 1, the both ends of pipe body 1 are equipped with first link 2 and second link 3 respectively, the diameter of first link 2 is greater than the diameter of second link 3, and the diameter of pipe body 1 towards second link 3 from first link 2 is the tapered, the top of first link 2 extends and forms grafting portion 21 towards its extending direction, the top of grafting portion 21 extends outwards and forms joint portion 22, be equipped with on the grafting portion 21 and connect lantern ring 4, connect the inside wall joint of lantern ring 4 and joint portion 22.

The utility model discloses a reducing pipe, be equipped with grafting portion 21 on the first link end 2 of major part, be equipped with joint portion 22 on the top surface of grafting portion 21, wherein cup jointed the connection sleeve ring 4 on grafting portion 21, and the connection sleeve ring 4 can rotate on grafting portion 21, so that the flange connection hole on reducing pipe and the pipeline carries out better correspondence matching, thereby reach the effect of quick installation, time saving and labor saving, and connection process convenient and fast, furtherly, be equipped with on the connection sleeve ring 4 with joint portion 22 assorted sealed recess 41 and sealed protruding 42, and be equipped with sealing layer 211 in grafting portion 21 inside, so that reducing pipe can be higher with pipe connection's sealed ability, the life cycle of extension reducing pipe.

As shown in fig. 1 to 4, the arc-shaped connection surface 11 is disposed at the boundary between the insertion portion 21 and the pipe body 1, so as to improve the connection strength between the pipe body 1 and the insertion portion 21, facilitate the passage of the connection sleeve ring 4, and facilitate installation.
