Background

The eccentric large and small head refers to a large and small head with the circle center not on the same straight line, and is mainly used for pasting a wall or setting a pipeline in a pasting mode so as not to occupy space, and connecting two pipelines with different calibers simultaneously to change the flow. Because the openings at the two ends of the eccentric reducing pipe body are arranged non-concentrically, when liquid reaches the other end from one end, the flow velocity at each position in the eccentric reducing pipe body is different, so that the phenomenon of turbulence is generated, the generation of the turbulence can cause the vibration of a pipeline, and the service life of the eccentric reducing pipe body is further influenced; due to most of the large and small heads in the prior art, the thickness of the pipe wall is almost the same at all positions; in conventional use, the smaller end of the pipe diameter is relatively higher than the larger end of the pipe diameter in the large and small heads, so that after long-term use, the damage degree of each part in the large and small heads is different, and the service life of the large and small heads is easily shortened.

The eccentric reducer disclosed in the chinese granted utility model patent application publication CN201820804532U can prolong the service life of the eccentric reducer due to the eccentric reducer inner tube, but actually the eccentric reducer is connected to the water pipe through the flange plate to work, but is easily damaged under the long-time work of the flange plate, and the current eccentric reducer is not convenient for replacing the flange plate.
